Figures that is what I was afraid of. Why does the 240 rotors cost so much more than the 280z? thanks for the info

Hello everyone, I am searching for a simple answer and after 20 min on the FAQ I cant seem to find a clear answer to my question. I am running a 72 datsun 240z with standard brake rotors up front and calipers. My Rotors are warped bad and need to be replaced. Looking at several websites, blackdragonauto.com, motorsportauto.com. etc. There seems to be a differeance between the front rotors on a 240z and a 74 260z. What is the differance besides the 260 being slightly thicker? Are the hubs the same?? Can you bolt on a 260 rotor on a 240??? I do want to go ahead and bolt on the toyota calipers when I replace the rotors but I am not sure which ones to use. I am trying to keep this on the cheap, my car is just a daily driver and occasualy horseplay, thats about it. If anyone has any insight I would greatly appreciate it. thanks

Might need some more information like make; model type of rear end, and transmission?? Before we can help you.

NewZed, You are correct I forgot to post the year, I have a 72 240z, thanks for the links. Between the original wiring diagram and nullbounds link I should be able to figure it out. I just didnt want to start spark chasing If I didn't have to. Thanks again!!

Hello all, I seem to run into an issue with my turn signal lever and headlights. For some odd reason the wiring got hot and nothing works. All the wires on the boad on the lever is black and some are burnt through. Obvisuly I had a short or a fuse that didnt pop when it should have. Here is my million dollar question. I would like to rewire my entire car using a painless wiring kit, I would even use GM flashers and fuse box. My question is, does anyone have a wiring diagram or color codes of the wires on the turn signal switch and what they go to. Hot, Ground, etc.I searched the Archives but cant find anything. Its not like I want to hook up power to my car and start testing every connection, something else might fry. I would like to solder the new wires to the old switch to keep the nestaligic look. any thoughts or Ideas?? I seem to be a t a loss at this point. I just figured 30 + years of harsh climate and mice that all my wiring should be replaced. Any Help would be appreciated or a link would be gratefull. thanks again. DatsunZman04,

I bought a 240z that had a lost title that was abandoned on farm in MO. I went through all the steps and paid $200 for the car but all I can get is a salvage title since I filed for a abandoned vehicle title. 3 weeks of Paperwork through the HWY patrol. GRR but I didnt want to see the car get crushed. Does this bring my car value down yes!! But I have the satisfaction of knowing that it was never in an accident and didnt need frame work done. Value is only in the mindset of the person who owns the car. If your not planning on selling it in the future, then go for it if thats what you want.

I had one break off into the head/block and had to weld a nut onto what was left to try and back it out. Before it was all said and done I messed up the threads so bad I had to re -drill and use Heli -coils just like mentioned above! It seems you have these problems more frequently when matting a alumminum head to a cast block or vice versa. A good torqable anti sieze will save you some headaches down the road. Thats my only advice.

http://www.xenons30.com/cams.html Heres all the info you will ever need to know.

Heres a Pic of something similar on what I was trying to achieve.

We can always change the needles and adjust, but on the Datsun inline 4cylinders they can run 2 SU roundtop carbs on the motor, so whats the differance by adding one more carb per 2 cylinders?

I had a crazy thought rolling around in my head and was wanting to get all of your opinions on the subject. Why hasn't anyone built a custom intake and linkage to run 3 SU carbs? I know its easier to buy a set of triple mukinis or solerex for around $1,500 to $1,000. So my question is what would be the downfall of running 3 round top su carbs?? I can make a template and plasma cam a flat flange and custom make a intake to bolt on 3 SU's. Now I know that the linkage would have to be redone but it's doable. . The Benifit 1. Everyone has a set or two of Su carbs laying around. 2. It's a different look. 3. performance might possible be the same. 4. I can make a intake for less than a couple hundred at my shop, plus I can do my own powdercoating. Downfalls???? I leave this all open for your guys suggestions, you wont hurt my feelings any just let me hear what you have to say!! DatsunZman04

Yeah, I kept the radio but already deleated my center vents and switches, All I have is fan on/off for defrost if I need it. I was just trying to see what make and model everyone was using to modify pillar pods to make them work. Cheap as they are I guess I can buy one and start molding it to the shape I want. Thanks for the info.

I think I need to clear the air out there on my posting and the comments made by Tony D. I messed up when I said the E31 Head had the Highest Compression Ratio of the Z series engines. I never Included the off the wall ( rare) heads like the E30 or the 05L. My bad for assuming he was from the US, where finding a old SKYLINE, LAUREL, Leopard, or a Gloria head would be a task in itself. All heads for these cars are becoming rare due to their age Inclunding the basic ones. As far as my absolute statement? All I did was give more information on the heads thats Tony provided that I left off. I did not give out bad information about the E31 head, I just told him the basics. I believe Tony, is one of the most experanced Z ethusiast out their and I would take his advice anyday, but I think his comments on Bad Information where a little bit unecessary In my opinion.

L20ET = O5L Head L20ET engine in an C210 and R30 Skyline The L20ET is a turbo engine developed by the Nissan Motor Company. It is a 12-valve, 6-cylinder, fuel-injected engine with a single chain driven cam, turbo (non intercooled), and a non crossflow head. It produces 144 hp (107 kW). It was released in the early 1980s[citation needed] and fitted to the Skyline, Laurel, Leopard, Gloria, and Fairlady Z lines of automobiles. The E30 Is also a rare head to find in a Datsun z. I was basically giving him the basics of what came stock here in the US.

The E31 head had the Highest compression ratio of the Z series heads, they came off the 70-71 z. BUT!!! they also had the smaller valves. Most people install the bigger valves in that head to make them breath in the 70's to have a budget racer motor to run on High Octane fuel. How to modify your Z engine book would tell you everything about interchanging the parts and the cc's of each head. I hope this is somewhat helpful. http://www.amazon.com/Modify-Your-Nissan-Datsun-Engine/dp/1931128049/ref=sr_1_2?ie=UTF8&qid=1378242751&sr=8-2&keywords=datsun+z+how+to+modify

You can always use plasti dip a chrome set black and it will never hurt the chrome finish. You can get the best of both worlds that way and see what looks best. One can is $15 at wal mart or autozone. It's just an option.

PMC, Do you have a number I can reach you guys? or a website I can take a look at?? Thanks

I unfortunately have more sense than money. We were just spit balling some combinations if money was no option. Obviously for that kind of money you could put just about any combination in a old Z. I like hearing other peoples wild builds and how they achieved it. When someone has extra parts laying around they always want to know their options on what to do with them and achieve the best result. I appreciate evryones thoughts on the subject, I am just going to locate a L28 block and bore it out and get a new set of pistons DatsunZman04

Lets say I have a Vo7 inline 6 block (Diesel) and a decent reworked gas Head, All I would have to do Is locate a rb30 crank and have it machined down?? What rods would you use? Obvisouly you would sleeve the block to have a 89mm or 90mm bore. Maybe I need to do some researching on this setup because I know where theres a complete 81 maxima ( diesel) that is just sitting in a driveway. Just trying to put together a build list in my head. Thanks XNKE

xnke, Your suggesting a VO7 block, (which is a 80' maxima diesel block) add sleeves and then bore it out?. RB30 crank from a rb30det? Sorry Ia'm a little confused on the parts list here. Clue me in ohh wise one.

This is a different concept, DESTROKING a L28 with a l24 crank. Keeping a higher cubic inch/ bore diameter block with a shorter throw crank. Is this like compairing a stock 350 sbc vr a 400 block sbc destroked using a 350 crank to get a 377?? Kind of compairing apples to oranges here sorry. What would be all the benifits of doing this vr using the longer stroke l28 crak or the vo7 diesel crank?? in a 280 block??

I say its a fuel issue somewhere. What do your plugs look like after it does the hesitation, are they fouled?? Or they white? Vaccum leaks, bad fuel or fuel pump would be where I would start. Can you hear the pump kick on when your keys are on acc? to let it build up pressure before you start it? A 25$ fuel pressure gauge would tell you a lot, get a fluid filled one it will be more accurate. Just tips where I would start, I hope that helps.

In Missouri 90% off all junk yards have crushed anything older than a 1985 model car due to the price of steel going up. Like I said my options seem to be stuck with the lawn ornaments or just by luck come across one. I wish I could find a set of triples on a car. I doubt there's a mechanic around here smart enough to rebuild or tune a set. Diesel wet liners?

CTC you are correct, The HOW TO MODIFY DATSUN ENGINES book called it a 3100 AKA (E31) High compression head with lilttle valves I take it. Do you need any l24 blocks I would be willing to trade? My problem is I live in Missouri and everyone wants to sell you a rotted out 280 car for 1500 when all I want is a block/ rotating assembly. Everyone thinks their lawn orniments are worth thousands.

Thanks for the help, Maybe I just need to have the machine shop check and see what the max is on my best looking block. I just figured someone had to try this just because the abundance of L24 blocks vr L28. I just wanted the 89mm because I can get my hands on a set of pistons cheaply.
