Hey guys, so I have the story of the morning. I almost never drive my 240z these days. It lives in the garage as a storage shelf sadly. It just turned 40 earlier this year. So I decided it was time to take it out and run to the gas station this morning for a monster energy drink and gas. On my way home I got to my long driveway that goes up hill and decided that the old tires were a bit slippery from sitting. So if Im honest I will tell you I am not nice at all with my Datsuns. In fact Im a little rough. So I did a burn out all the way up the hill in my driveway. I get to the top and thud. It free revs out and I start to roll back. WTF? I turn the car off and get out to inspect. I dont see anything. I really expected to find a half shaft hanging in the breeze. Nope. Nothing seems wrong. I put the car in gear and let it roll back it just starts to roll freely. So I pull the shift boot back and let it roll some more while in gear and the driveshaft isnt turning. So I know what has happened. Something in my 40 year(94.5K miles) old diffy has given up the ghost. I sit there and contemplate the circumstances and I cant think of a better way to go than a phat roast season up a hill. I almost made it into the garage. Another 20 feet and I would have made it into the garage. One of the mustache bar bushings has been out since long before Ive owned the car. Its always had a thud shifting hard into gears and on takeoff. So Ive been looking into getting an R180 from a 200sx for a little bit, but now I guess its time to jump on it. I believe I may end up purchasing a stock 240Z r180 for now just to keep it on the road, but its time to replace the whole unit and go with better gears. The funny thing is though, that I have had an R180 in my stock 260Z (up until its 35th b-day and 140K miles) and It went 3500 miles with no gear oil in the pumpkin without any problems. So I was under the impression that these were pretty bullet-proof internally. Well at least for stock conditions. Like I said I was expecting to see a half shaft hanging in the breeze. I cannot wait to pull it out and pull it apart for my trophy! I have my choice of R200 3.9 gears or R180 4.11 gears. So other than my little story I have a question. In my 260Z now I am running 3.7 gears and before that it was 3.9 gears and before that was the 3.54 R180. Personally for that particular car with an engine swap now I preferred the 3.9 even though I now have 3.7 gears in it. In the 240Z Im running a ZX 5spd and I was hoping I could get some feedback on the 3.9 vs the 4.11 gears if anyone is running them in a mostly stock 240Z with a ZX 5spd. Is there a preference? Im trying to stay with the R180 as I dont want to convert the half shafts and mustache bar, but so be it if its the only way to go. What is your preference for gears in this type of setup and why? Its a weekend worrier/garage queen and when Im done will have a good amount of torque from a 2.7L L24. Thanks for your opinions guys

Oil consumption can be very bad for your tune esp at high load and cruise. Besides why would you build a "320-350rwhp range at 16psi boost" L series and not make sure it was perfect to ensure longevity of your build? I actually built an L28et with around 320rwhp @ 18psi boost on a modified T3 turbo so I can attest to how critical everything must be for longevity. Slapping stuff back together without taking the time to ensure every little thing is right can and will be the failing point in any build. Now if you were a stocker and could deal with the oil consumption you'd still run into the same issue, but it wouldn't be as critical for longevity.

Found it, That is what I was looking for. I bet the booster I have bolted right into the stock 240Z. 240Z with 280Z booster install

My thread about pedal boxes Hopefully that helps you a little. I seem to remember all the early stuff being interchangeable. That is to say all the individual parts not just assemblies. For example the big single auto brake pedal can come out and the std brake pedal will bolt in its place into the box and there is a provision for the clutch pedal on the auto pedal box so all you need is the pedal and hardware and you can bolt it in. I think the bulkhead may be tapped for the clutch cylinder, but there is a block off plate over it, but that could be wrong. Its been 10 years or so since I last messed with an autobox S30 just so you have an idea and my memory has failed me often lately. GL!

Im not going for easy. This MC eliminates the distribution valve and other inline devices as well as provides more volume than the ZX MC. I believe its a 1" bore MC. Its not dissimilar to the MC's on 300zx or Q45 models. So I am re-doing all the brake lines and the meter valve in the back for the old drum system. Besides I have a working 260Z master cylinder and booster unit that is coming out of the car. That system isnt good enough to stop the RB powered Z in my opinion. A Request: Anyone with a std 240Z Brake Booster or Pedal box, would you please take 4 measurements for me? From center to Center of the holes/studs along all four sides that lineup with/go through the bulk head? I believe its a rectangle, but it could be a trapezoid. Thanks!

Im sure this has been covered in the distant past about swapping 260Z and 280Z brake boosters onto a 240Z, but I cant seem to find anything now. I have an upgraded brake booster and MC that was pulled from my 71 240Z and I went to install it on my 260Z. So Im trying to do the opposite by putting 240Z parts on a 260Z. Its a significant upgrade. What I have found out is that the holes in the pedal box and bulkhead appear to be in a different pattern. Has anyone else noticed this? Im curious because the 240Z I had was modified and though the parts are all Nissan the booster and MC are from something much newer(circa 94ish) and the PO may have modified the bulkhead and pedal box without my noticing it. I do not have the old 240Z pedal box or car for reference anymore so now I just have the booster and MC to go off of. The fix is fairly simple, drill 4 new holes to mount it, but the holes interfere with the stock 260Z pedal box gussets so it a pain and might be easier just to change the box over to one that works and only drill the bulkhead.

Gotta love how that system works... Anyway the current info regarding cost limits and compliance are all in the "CAP" or Consumer Assistance Program papers. They are available at any local Smog shop(or should be) as well as local BAR office, and maybe DMV. You should be able to find those papers online as well. I dont believe they allow a maximum spendature and then cut you loose anyway anymore. Here is some basic info: Consumer Assistance Program basic info and IF you click HERE you will get the CAP Application with some info on it as well about the options available. You will have to do the rest of the research on your own(and its out there).

Damn sorry to hear that. That is how the law is written though. Most of the time things like this dont happen here in Cali. It all comes down to the individuals that enforce these laws and YOU the driver/owner. Cross your fingers/kiss they arse and hope they dont view you as the 'A-hole' on the road and find THAT reason to toss you into the system. OR drive right and show no obvious signs of modification to your car. I have a LARGE 3" ID GReddy muffler with like a 4" chromed exhaust tip on it. That tip stays as black and nasty as I can possibly get it... The rest of the car still gets a car wash though. Whats really sad is that the RB25DET with no CAT is cleaner than the L-gata(esp @ idle). So a swapped RB into a certain old Z is actually achieving better tail pipe emissions than the original option L. My last emissions run with the RB25det showed high HC's, but I already know about the leaky 100K mile valve stem seals that are in that motor. Most of the CHP around here give me the thumbs up when they see me drive by. Since I discovered that the cars speedo has given up the ghost Im always thinking Im speeding when Im actually not. It gets tricky though, the speedo is only 5mph at the bottom and by 70 mph the speedo reads something like 95mph. GPS backup has been nice in the past few months since this discovery. As far as the old skyline which model do you have? Hopefully not a real GTR. Did they go after the safety criteria as well or just the engine?

Ill PM it to you Like I said they may or may not ask for a certificate of compliance/non-compliance. My bad it looks like they may have nailed them as annual reporters not biannual."Government Fleet: Smog Check inspection requirements apply to government fleet vehicles. To help verify compliance, government fleets are required to submit an annual inspection report (Annual Reporting Transmittal - Form 79-21) to the BAR Fleet Operations Unit."

Did you know that the state "ca exempt" plated vehicles are STILL REQUIRED to attend biannually the enhanced smog program. I have actually never done one, but there are some special instructions for them that you have to know in order to be able to answer questions on you smog license test and to do them if you ever do end up with one. The exact information is hidden in that "Smog Check Reference Guide", which can be found on ARBs website that I listed on PG 2. Its location is Pg 1-35 under Section I, 1.11.3, Fleet Vehicles, Government Fleet. And they may or may not require the Certification of Compliance or Non-Compliance. There is another "catch" for legislators and for ARB's members when it comes to adding those pre-76 vehicles back into the program. CAP, that is the Consumer Assistance Program. The state knows that they would end up having to pay to keep those cars on the road as well as pay to take them off. Just like Tony Says, "they just don't want to TEST EVERYONE when it's diminishing returns".

My wording was a little bad, I was not implying you were an 'idiot'. I should have said it was incomplete. Your example was/is very good. It is my understanding that emissions standards for trucks and for the same model year passenger cars were different and that is the main idea behind not allowing the swaps(not sure about light trucks). I have never looked up the specifics behind that though. The swaps are 'promoted' as long as the passenger vehicle retains the same emissions standards or better(newer model years). Those light trucks ie Ford Rangers, Toyotas, etc. had the same power plant, but you can betin most cases they did not have the same internal specs as the passenger vehicle counterpart. Stuff like compression ratio and cam specs were different and I would think(just guessing without looking) that the emissions standards for those 'commercial' vehicles would be a little lighter than the passenger vehicles. Just a guess and I could be wrong.

Fidanza just called me back again. They are saying that I have the right cam gear, but its not suppose to have round cut gears. I bought them third party, but since I have all the original packaging and parts they said they would take them back and re-send me out the corrected parts OR if they do not have them in stock find me and send me no charge replacements. Talk about customer service... definitely going to buy other Fidanza parts if this is how they treat(pun intended) customers!

Not quite, You cannot use a truck motor in a car, or an older than your current chassis model year swap. You can put a car engine in a truck though. You can make a motor swapped vehicle compliant if you retain all of the original smog equipment from the donor vehicle. So, for example, to be compliant with a 1972 v8 swap in a 1972 Z, you'd need All of the emissions related devices listed on the Emissions label under the hood(aka ECS label) of the donor vehicle or as that donor vehicle is listed in the ECS manual that almost all smog shops have. Ensure that you have California ARB compliant aftermarket parts or "O.E." replacement parts. Check out that link I posted on pg 2 for the "Smog Check Reference guide Appendix E I think it is. All about motor swaps. In the past 10 or 11 years that I have owned my 260z I have only been 'harassed' once. It was 4 months after I bought the car and the muffler fell off the stock exhaust and I shook the CHP's car windows as I passed him down a 2 lane HWY. 6 months later the car was swapped and I have not been pulled over in that car once since then. I have had CHP, Sherrifs, and city Police all wave and give me thumbs up for my ugly little blue turd that has a huge GReddy fart can on the back is obviously lowered and at one point slammed, and has a bunch of gauges where the stereo should be. My car is exactly what they are looking for in modified cars on the street, but I guess the paint is so bad they dont give it a thought or something. Maybe I need a wing just to tempt fate. Ill probably jinx myself by posting this.

I gave Google a whirl. Pretty much everyone has been saying that the "belt is making noise because its breaking into the new gear". Im not sure I trust any of that. Fidanza stands by the product saying they have not received any complaints about it in the 2 or 3 years(I cant remember for sure) they have made it. The car was driven around a little bit today and the noise is lessening and not constant anymore so there might actually be truth in what the other website ppl are saying. Its gonna get pulled back apart though to be sure nothing weird is happening and Im seriously considering putting the stock cam gear back on for now. Ill get some pictures up later if I have a chance.

Basically if you want to do an engine swap on any vehicle you can use "Appendix E" of the "Smog Check Reference Guide" which can be brought up at ARB SMOG CHECK REFERENCE GUIDE to get your car setup the Legal way. I think most of us fall into the other category... including myself, but they dont check unless like I said, you piss off the wrong person. MS2 would not be legal. Im pretty sure it says Off Highway Use in Ca somewhere on their website or something to that effect. AB2683 Another great quote in its entirety: Like I said my copy of the laws are for a Smog Station and it has sections of Laws, Codes, and Regulations that a smog shop would need, but its really not complete. The above quote has the exact letter of the law as my 44011 section should read above. Its spelled out nice and clear how its exception from inspection and nothing else.

And this is why the situation is so miss-leading to others. Cops typically are not concerned with these older cars and why should they be focused on such a small percentage on the road when they are mainly after the newer non-compliant vehicles if at all. If you piss in the wrong CHP's Cherrio's sort to speak you might find yourself in a really bad situation for sure. Its the CHP's job to keep the roads safe so they are a bit more focused on the regulations. Like I said above Ive seen cops do it though. The Police will call in a CHP and in the worst cases the car will be subjected to a ref check if its suspected that it is purposely NOT in compliance with emissions regulations despite model year. I was not witness to any of the ref inspections that followed so I cannot provide that feedback, but Im sure you could ask the local ref what they would do in that situation.

And this is where the ref and the rest of the state will get ya. If your car irrespective of model year was mandated to have any kind of 'emissions' equipment under "( No person shall operate or leave standing upon a highway a motor vehicle that is required to be equipped with a motor vehicle pollution control device under Part 5 (commencing with Section 43000) of Division 26 of the Health and Safety Code or any other certified motor vehicle pollution control device required by any other state law or any rule or regulation adopted pursuant to that law, or required to be equipped with a motor vehicle pollution control device pursuant to the National Emission Standards Act (42 U.S.C. 7521 to 7550, inclusive) and the standards and regulations adopted pursuant to that federal act, unless the motor vehicle is equipped with the required motor vehicle pollution control device that is correctly installed and in operating condition. No person shall disconnect, modify, or alter any such required device. " and others then you are breaking the law by using the vehicle on the road if it has been 'tampered' with. The first emissions mandates came out in 1966. There is no exception from these mandates. In fact over the years laws have been amended so that the mandates were more stringent in some cases than when the vehicle was made(such as tail pipe emissions tested). So you will find NOTHING to state that your car isnt required to retain its original emissions equipment anywhere in the law. The laws I posted only talk about the Enhance Smog Program stating that you are no longer required to adhere to the bi-annual inspection(You are exempt from the inspection only not smog regulations). You will have to dig through another law book to find this and I dont even remember which one at this point. The older copy of the CVC I have was MUCH more clear on the subject before the last revision by Arnold. John C states and is absolutely correct here: "None of this has anything to do with the biannual or sale smog inspection program that I mentioned above. Its completely outside the program and is a law enforcement action." In fact the test stations cannot deal with a vehicle older than 1976 in their system. When the tech trys to smog an older pre-1976 vehicle it wont give the tech the option to run it. The state ref is the only one who can determine if the car is compliant, which is why you get sent there by an officer. Its not in the abbreviated law books I have for the smog station because I dont deal with 75 and older, but those 1975 and older vehicles still have mandated emissions equipment that has to be maintained in order to be legal. BAR is seriously talking about all commercial(no passenger vehicles) 1966 and newer(so ALL pickup trucks without the 1AAA111 style plates) be brought back into the biannual program because they are the worst offenders in these roadside tests. If you want to get to the bottom of this call the state Ref and see if he can give you the code you need to prove or dis-prove this. As a Smog tech the law gives you authority to 'repair' or 'replace' emissions equipment. You must be a Ca State Licensed Smog Tech to make repairs to any emissions equipment though. This IS enforced and there are a bunch of related Laws Codes, and Regulations on the subject, in fact more so than who is and is not suppose to participate in the Enhanced Smog Program. In fact I had my dates off. I keep thinking 1966 is the year it started. It was just the first year for tail pipe emissions. In fact it appears it was 1961 for the first emissions mandate(Im a youngin so I was there to be sure), but in fact ARB lists: 1963 Positive Crankscase Ventilation requirement of 1961 went into effect on domestic passenger vehicles for sale in California. First Federal Clean Air Act of 1963 was enacted. Empowered the Secretary of the federal Health, Education, and Welfare to define air quality criteria based on scientific studies. Provided grants to state and local air pollution control districts. 1964 Chrysler exhaust control system was approved by the Motor Vehicle Pollution Control Board. Four other independent companies also received approvals. 1965 Reliable measurements of ozone concentrations began to be recorded. The maximum one-hour ozone concentration for the year in the South Coast Air Basin was 0.58 ppm. Federal Clean Air Act of 1963 was amended by the Motor Vehicle Air Pollution Control Act of 1965. Direct regulation of air pollution by the federal government is provided for, and the Department of Health, Education, and Welfare was directed to establish auto emission standards. 1966 Auto tailpipe emission standards for HC and CO were adopted by the California Motor Vehicle Pollution Control Board. First of their kind in the nation. More Here: http://www.arb.ca.gov/html/brochure/history.htm You have to find the mandates for these vehicles and you will see that these regulations are put on these cars, but there isnt an amendment that says they are no longer required to adhere to the regulation, or that there is an expiration on the regulations, only that they must be on there and that a state licensed tech(smog license) is the only person that is legally allowed to repair, or replace emissions related equipment.

When I did mine 2.5 years ago I built the cross member to accept the stock R33 transmission mount as its the same as a lot of other newer Nissan models. My main goal was to get the engine and transmission level with the ground/frame rails and centered in the car for mostly oil reading purposes. I then installed the whole engine/trans into the car with about 2" of height off the center flange of the differential. So its installed so that the output shaft on the trans and the diffy pinion angles are as close to parallel as possible 2" apart. So I ended up with the same u-joint angles on both sides. I knew straight was bad not because of loading but because the U'joint bearings needed to spin to load them evenly without abnormal/excessive wear. So placing the driveshaft at any minor angle would achieve the bearing rotation I needed. I believe and I could be wrong that my 260Z(one that isnt totally dissimilar to a 73 model) stock actually had the stock transmission offset to one side and almost/but not quite level with the pinion angle. Take it for what its worth, but I have no vibration issues at all. Maybe its a case of dumb luck that mine worked out or maybe its because I have a soft transmission mount that doesnt transfer all the vibration into the car IDK?

All I see in there is stuff concerning compliance testing and specifically exemptions from testing not exemptions from the original smog requirements imposed upon older vehicles. Smog devises were implemented back in about 1966 with the first PCV systems becoming mandatory(Im not going to even look for that law). I have CVC, CCR, partial Penal, partial Civil, partial PR, and H&S on CD in PDF as related to the Laws and Regulations Pertaining to California Automotive Repair Centers, Licensed Smog Check Stations, and Licensed Official Lamp, and Brake Adjusting Stations. BTW short story here, CHP and Local Law Enforcement knows the students attending Universal Technical Institute of Sacramento Ca have all sorts of vehicles and that they are likely illegally modified being the wrenching types. The school tells students from day one and reminds them every 2 weeks or so that they should abide by all laws when leaving campus and even in the greater Sacramento area because Law Enforcement tends to be more harsh on the UTI crowd as they should 'know better'. Most cars that were pulled over at that campus received speeding tickets or exhibition of speed tickets as you might have expected. A lucky few had their cars towed for illegal modifications. And to get to the point there is a very small percentage of the student population that drive older than 1976 but newer than 1965 that were pulled over and yes FORCED to pop their hood for a compliance check. At that point the officer was well within the law to send the student off to the referee for a real compliance check and a few had to go(they esp sting the outta state non-compliance vehicles despite model year there as they are technically reside and are being driven in Ca during school). Ive seen it happen and while I attended school made it a point to be a safe driver(because my car isnt compliant in many ways though it actually passes the emissions test).

If you have your truck registered to a PO box out of state you better live out of state with proof like valid DL with a real physical addressed on the DL! Or your going to have problems with the CHP. As far as an Oregon plated vehicle on Ca roads, yes they can be pulled and checked. Any CHP officer can decide to check ANY vehicle on the road for compliance. Since the purpose of those roadside tests were to 'sample' what is really on the road, I seriously doubt a real ORE driver would actually be cited or made to comply with the laws during a passing through. My father-in-law lives up in Cove Ore and visits us here in Ca often. As long as he is in compliance with ORE law he can be pulled over here in Ca but not forced to comply... and we actually have a letter of apology from the CHP from such an event involving trailer registration(in ORE small trailers dont get license plates!). That actually falls here: V C Section 4000.2 Out of State Vehicles Certificate Out-of-State Vehicles: Certificate 4000.2.

Alright guys, My head hasnt been the straightest in the past month as Ive been on pain meds so please excuse any stupidness I may blot out or if the answer is apparent as the nose on my face. So what has happened is I installed a Fidanza Adjustable cam gear before I needed meds. So Im fairly sure of my work. I had my buddy come over and button the covers up last night. Everything is set straight up until I get to dyno it in. So after fitting the covers we started getting a oscillating humming noise. It was apparent it was near the top of the engine after a minute of running. I was hoping it was the alt belt. Anyway, so I had him pull the top timing belt cover off again. We re-installed the CAS with some washer spacer to prevent it from rubbing the cam bolts on the timing gear. After re-starting the engine I could see the belt 'shifting' with the noise across the new timing gear. I applied a little bit of pressure with the round end of a hard screw driver to add tension and the noise quieted down. So we thought about it for a bit and decided we had to pull the bottom front cover off and adjust the tension on the timing belt up a bit. So an hour later we are ready to start again and I have tightened up the tensioner a bit this time after a couple revolutions of the engine to be sure the slack was accounted for. The engine still starts and the oscillating humming noise is still there. So here is where I go 'what is different'. I grab the fidanza adjustable cam gear I still have in the box, because I got a pair of them for a good deal and check out the extra gear I did not install. I grabbed my stock exhaust cam gear at this point an hold them next to each other. The stock cam gear is squared the same as the belt shape. The Fidanza gear has the same general square shape but is cut in a semi-circle instead of the square shape. The belt fits the semi-circle but there is a gap at the bottom of the belt teeth to the cam gear. At this point I am speculating my belt is tight enough and that the shape of the Fidanza gear is causing the noise much like knobby tires on a road surface because of the air gaps from tire siping. The part number on the Fidanza parts are for RB and I confirmed it via phone with Fidanza even before I installed it. So its not like the gear was cut for a belt with semi-circle teeth instead. Should I be affraid of the supercharger like noise it is making at this point and continue to look for something that was incorrectly installed or does my conclusion sound valid? Thanks for the extra brains on the matter guys.

Very cool to see this old car making good progress. I wish I had pictures of the car from 8+ years ago to post up. The original owner, whom I have lost contact with would probably cry in joy in seeing her old Datsun looking this good and being cared for. Keep up the great work!

Dont clean the EGR unless you think you can prevent the carbon chunks from going down stream and into the combustion chamber. If it trys to stall that is a good sign that its flowing okay. Try and apply vacuum to the EGR on your other ZXT and compare? The FSM should have a specific reading for vacuum applied to the EGR. My 82 maxima FSM has all that. Keep looking. You should be able to test and verify. As far as timing goes follow whats on the hood label. Thats what their checking for. If its not specified how many degrees out that you can get away with, 3 degrees either way of spec. is acceptable. Thats about all I can tell you off hand. "Why is it so high at 15 then so low at 25? is it because of the EGR valve, or cat warming up, or both?" Both was my guess and still is from my first post in this topic "Hard to tell without putting my hands on it, but I suspect you passed the faster test cause you have a working EGR and the cat was getting nice and hot." The alcohol trick works on certain types of failures. Ive never done it personally, but have had friends try it. Im actually a Smog Tech, but I dont want to risk my license in this market Id be more specific on timing and alcohol if I thought I could give a clear answer. Maybe someone else will tackle the ins and outs of those. I just got out of the ICU burn ward so my head a little fuzzy on some things on account of them pumping me full of pain meds for 13 days.

Nathan, look at his O2 and CO numbers and rethink your vacuum leak theory... I still stand by my initial leave the AFM alone. It looks like he did a good job at finding any vacuum leaks. Good info just probably not relevant to this situation. IF there is no timing spec "range" specified the tech's official position is that if its within 3degrees + or - of the spec its good. Most techs wont rev the engine up and down when they cheat. "Most" cars will heat the cat up by free reving around 2500-3000 rpm. For TSI tests this is why there is a "cool down" period if the tech fails to stay in range. The long the tech is out of range the longer the timer will be for the cool down period. Im honestly unsure how the machine determines what numbers to printout, maybe average or? Its kind of a big secret even to the techs. They do have the capability to preform continuous sampling with these old machines. If the machine "sees" what it likes it fast passes to the next test. If its seeing numbers that are close to fail or what ever criteria it has it holds it to the end of the test and its still a toss up whether it was a pass or fail. BTW Personally I have made a cat go Nuclear. Took a whopping 15 seconds. All I had to do was unplug the AFS and hold the rpms at 2500... cat was at 1422*F before I realized what happened. Luckily it was a training vehicle. Here is something for you guys to check out. Lambda. Lambda calculators are a cool thing. Take your 5 gas readings and plug them in and you can calculate your AFR before it was burnt! 15mph reveals a lambda of 1.013 which is 14.9AFR 25mph reveals a lambda of 1.006 which is 14.79AFR Id say his air fuel ratio is ABSOLUTELY DEAD NUTS.
