http://www.atlanticz.ca/zclub/techtips/EFI&fuel.htm Find the EFI bible. Read it and run all the tests it recommends. have fun and rejoice in your newfound Scripture (with apologies for minimal blasphemy:))

First off, go get some NGK plugs. Seriously, before anything else. New NGK plugs (replacing not INCREDIBLY old NGK plugs) have repaired a not entirely dissimilar problem for me on my 87 subaru. yah, apples to kumquats, BUT autolite == crap. Secondly, go back and check your TPS a second time. If it check out, then try to find the associated pins on the ECU plug and test the TPS operation at the ECU plug; this will ensure that the wiring to the TPS isnt janky in any way. (this sounds like a TPS problem to me, but thats just a SWAG) Thirdly, gasoline and carbon build up can look ALOT like oil on the plugs. What do you mean by "The smoke smells a little like gas, but a lot like fuel."?? And finally, when you say the engine wont "turn over" do you mean that when you crank it it doesn't even TRY to start? Most people consider "turning over" to be the rotation of the engine caused by the starter; if. by "turn over" you mean "try to fire" then some clarification is needed... if you mean, literally, that the engine wont turn over (IE immobilized, starter motor does nothing) then I am going to start asking questions about battery connections and grounds, etc. hope this helps

http://en.wikipedia.org/wiki/Desmodromic_valve I figured rather than ask what a desmodromic valve was, I would find ot for myself and answer the question for anyone else. GROSSLY oversimplified (I am fishing for corrections if I am wrong) it uses a second cam lobe (plus some other valvetrain hardware) to close the valve rather than springs, right?

no offense, but you are begging to be flamed on this. We are a very technical board here (I say we because the grownups are kind enough to let me play) and i suggest you read the stickies in the FAQ section, (expecially hyperlinked table of contents) the L6 section, and maybe even the Turbo and the Fuel Delivery sections further down in the forum. This "s30 model specific" forum is relatively new, and isnt going to get much technical traffic anyhow.

People have covered the "ZX->Z" fairly well, but as far as "Inter-S30" 240-260-280 body parts interchange, pretty well anything that isnt taillights, turn signals, grill, or bumper related is essentially the same.. NOTE!!! the doors from 1970-1976 all interchange with each other, although there ARE slight differences. HOWEVER the 1977-78 doors are a completely different beast. 260 stuff, early 260 bumpers, turn signals, grill etc were 240, later were 280.. (unsure about the "later 260Z" bumpers?) The 77-78 280Zs had different bumpers from the 75-76, but they should interchange. Tail lights can be swapped with some effort, front turn signals can be swapped with some effort (I know this because we used to have a 280 that had been re titled as a 240 and the turn signals and tail lights were the only things he did to it superficially to make it look like a 240; the interior was straight 77 280Z, down to the typeface on the gauges.) In short, the S30, regardless of model year or engine size, can be treated as one single model that underewent several minimal changes throughout the decade of the seventies. An 85 IROC and a 92 RS don't have the same tail lights (do they? i was reaching for an example and I'm 99% sure about that statement) BUT they should interchange right? Treat anything (exterior at least) with that kind of mentality, and inspect it if you can before installation.

I'm sorry.. but is that a Geo Storm Hatchback I see in the back of the pack there?? red car, white diamond on the hood... the grey and silver car in front of the Z almost looks like a subaru XT, but from that angle lots of cars look like each other (prelude, XT, heck it could me an MR2 or something totally else) Just had to ask.

Wow. Wow wow wow is all I can say. Somehow, they rewrote the cartoon that we all watched as eight year olds.... ..and they made a movie that simultaneously entertained a roomful of twentysomethings.. yet was still the same thing that made the eight year old within jump and bounce of the walls making that silly noise.. oh, and the dialogue between Prime and Megatron coming straight from the original movie.. CLASSIC. They have GOTTA put smokescreen in any putative sequel.. bugatti, heck, make him a 350Z. The whole chevy:autobot::ford:decepticon thing was kinda funny too.

Jiminy Crickets, when I think of how many parts collections ha just been pwned!!! My uncle has several bays fulla crap, and when we include the entire extended family its absurd how many Zs and roadsters, and an incredible amount of datsun and outboard motor stuff.. i am amazed. Or, I WAS amazed, until I saw this. on a side note.. what is this console with the gauges and what looks like a place for a stereo, bottom left of the picture, out of.. any clues? It looks like it might be made to go into a 240Z to provide additional gauges at the price of the ventilation controls? I dunno, the shape (and sheer number of instiruments contained therein) seemed to grab the junk collector in me, and I wanted to try to find one of those.

that post almost brought a tear to my eye. thank you, BRAAP. That's always been my word to describe it, and you echoed my thoughts (at least regarding the six) verbatim.

I will reply in the form of an epilogue: Analog multimeters are always best for testing devices such as the AFM on the early Z FI.. sometimes digital meters (even the best ones) can miss a bad spot in the potentiometer, that will always flicker a cheap analog needle.

Yes, I recall TonyD's posts regarding this fact.. I was trying to make sure I was recalling properly. Just to make it clear, this *is* only an issue under boost, and at zero boost naturally, there is no pressure in this line and no pressurized enrichment needed.. (I am just trying to fully analogize it with an FI forced induction system, which is all I know about.) Your needle valve system sounds interesting; as far as I can tell (like that's worth much) it sounds about right. This is a really neat project, cant wait to see this built. Regarding the placement of the thing, I was just playing the devil's advocate. There is no "right" way, I might've argued for AC compressor side if you had planned it on the other side.

sorry, it was a long and boring day. I obviously wasn't paying attention; I knew this but remembered it wrong. These things happen when I have a whole day with nothing to do but internet; its a price I pay for owning and driving a subaru (which needs constant attention) while i dream, plan, and research for my Z. Now that I think on it, it is the main TB for my subaru SPFI thats 38mm (yes thats right it is THAT small) I plead temporary retardation, your honor.

Hey man. You are an upright guy; good principles. The personality you have shown in this thread speaks volumes, and I hope you read all the grains of salt shown to you here and do your best to see where everyone is coming from. I think that overall, you've hear about the gamut of decent advice there is to give; however, I do agree that it has gone as far as it needs to (by that I mean, relative to boundaries regarding use of the forum) Apologies if any of my comments pushed the envelope a bit closer to that edge. In short, we are all trying to say that planning for your life is good; but in the end you cannot always count on reality to match your plans.

couldn't you obtain some of the hardware for mounting a power steering pump and adapt that to your purpose? I mean, with a supercharger (rather than turbo) you have the option of placing it on the less busy, less heat soaked side of the engine bay. I am not trying to nitpick, just making sure you have thought of everything I like this idea; what sort of compression ratio were you planning on running? also, refresh my memory.. the line going to the float bowls for the carbs from the SC; that is to add pressure to the fuel supply to held enrich the fuel mixture under boost, correct? am I at least essentially right?

is that secondary air filter for use when not using the supercharger? just making sure im understanding this right.. you are building a setup for "boost on-demand?" with NA for "normal" running? interesting....

Hey dude, do not take the quoted post in the wrong way!! His point was that you don't know jack about the man you are gonna be. You have plans, thats great, but what you do in the next five years is going to influence your life more than anything you have yet experienced... (true in 99.99% of 20th/21st century male american situations) Your relationship with this girl will alter you, your geometry teacher will alter you, high school football games will alter you.. and you have no idea what thats gonna be like yet. Thats all he is trying to say. I have been a hopeless romantic my whole life; when I was 9 my crush switched churches to start attending with me.. which entailed her family converting to catholicism, NOT exactly a simple decision, more of a process. A Hybridization, if you will (catholic jokes are the best.. but they come with a limited audience, sigh.) I had similar concepts in mind then; BUT even then, I knew somewhere in my head that to say anything like that was foolish. We moved out of rural north carolina and back down to south florida when I was 12; never saw her again, BFD. The single best piece of advice I have ever heard, bar none: Do Not Get Married Until You Are 25 (or close.) Quite frankly, women do not finish their full maturation process until sometime in their mid 20s.. some earlier, some later, but 25 is a good rule of thumb. Boys don't mature as fast as girls, right? that holds true until high school graduation, then things start shifting. Generally speaking, by the time a man is 21 he has made enough stupid mistakes that he is about 90% of the man he is gonna be.. but a woman at the same age (NOWADAYS, at least) still has FAR more mistakes to make before she really learns what is going on in this whole "society" place.. THIS is why so many marriages will break up. So don't just get defensive; we know your feeling. thats "THE feeling," and I hope you get to experience it more than once in your life. LOL, grabbed my first pair at a church lock in when I was 15. (Actually, it was a game of truth or dare.. so there were a COUPLE of pairs grabbed that night.. ahh, the memories.... The funny thing was seeing 2 of those pairs at another pairs wedding last 11/11. The times, they are a chaaang-ing....) Daeron == late bloomer, romantics aside. Anyhow, regarding your situation.. Give it some time. in a few weeks, maybe try to talk to her parents, or one of them (just speaking to one might make it easier on you) and do your best to approach them as an adult, and address any particular concerns that they might have with you. Make sure that they realize that YOU know certain boundaries need to be respected, and that you aren't just burning to get into her pants. The fact that you are here asking for advice leads me to believe that you are a respectable type guy, and that you AREN'T burning to get into her pants.. yet. In time, if that comes up, well so be it, maybe the parents don't really need to know yet (keep it wrapped ferchrissakes) BUT ONLY LET THAT HAPPEN IN TIME. one of my stock phrases is somewhat appropriate here.. "Patience is a virgin." I substitute virgin for virtue for comical purposes normally.. but here its doubly appropriate. Haste makes waste, and you have nothing to gain and everything to lose by being in a hurry. The most admirable high school relationships are the ones that start early, last a few years, then end before your graduation so that you gain the experience to move on while you are still in an environment where it is easy to bounce back. (ie surrounded by lots of pretty girls that you can talk to and "get to know" Trust me, once you get out of school if you should HAPPEN to go back to your high school in the next couple of years you will be AMAZED at the amount of tail walking around you.) Its like the old man in the ads said: Life is a Journey!! Enjoy the Ride!!

Thanks for the clarification, but my intent in pointing towards "larger injectors" was merely as attempt to point towards another step to complement the manifold. I guess YOUR point is that, a mild cam is more complementary than non stock injectors. Honestly, I just wanted to sound off in saying that IMO this manifold (or a similar one) is probably an IDEAL first step in modding an engine.. and I am curious to see what difference it makes by itself, unless a cam change is really needed to take full advantage of it. Really, i was just trying to find a way to scale down the pipe-dream of dyno testing the difference made by any combination of ignition, fuel supply, and air supply that can be made with this type of free-flowing intake.. but of course if I REALLY wanted that data, I suppose I would need to do it myself. Eagerly awaiting dyno results. thanks for pointing out the shortcomings of my previous post.

http://forums.hybridz.org/showthread.php?t=123301 that should answer some of the sending unit questions

hows about a shot of the front with the hood closed?

can we say bionic Z???? major impressive work, my man...

That was my friend Phizinza.. hes actually from Oz, not NZ.. (we are subaru buddies, but old gen soobs.. so I cant give any positive answers on the soob rear end questions.) His thought was to try to get datsun guys and subaru guys together on a potential buy-in, if i am not mistaken.

look in the ignition/electrical forum.. someone just had a new sticky post added there and it goes over the entire turn signal/hazard system. the 240 is not QUITE the same, it uses different pieces, but the design of the circuit is the same.

Not in this sub forum.. My point was that with a little effort, all the users can submit bits here that could be integrated into the initial post... and that the S30 forum is the ideal place for such a sticky. The more stickies we have, and the better indexed they are, the easier it is to point people towards all of the abundantly overposted information on the forum. In essence, I am proposing that we as users each make a tiny effort to help build this putative sticky into another place to point people who ask the inane questions rather than search for answers. The easier and more exhaustive we can make the search for their answers, the fewer we will have to deal with the posts (and the more SAVAGE we get to be when we yell at them to SEARCH!!!
