Sperglord Firecock posted:It's not a factory turbo. Then I think it is likely a 86 model year. OK, so since you seem to have a big stiffy for a Z31, here is what I would do: Either: 1: Sell the car as is (or, running decently), take money and buy and keep a look out for an unfucked Turbo Z31. They are out there and tons were sold. 2: This was touched on earlier, but maybe get a hold of the previous owner and ask him if he lowered the compression or did any internal engine modifications. Just fire him an email if nothing else. If not, bring it back to a stock NA. Do the clutch, sell the Turbo and assorted doo-dads to some sucker on ebay or something. This will also benefit you by learning to wrench by un-loving it (which you will need to do if you plan on having a mid 80s car as your DD). Bank the money and keep eyes open for a Turbo. 3: Keep car as-is and live with it. I know you are really looking at #3, but seriously give 1 & 2 thought. It's just a car and you will have another that you love even more. Trust me.

Sperglord Firecock posted:It's not a factory turbo. I didn't read that before and that changes everything, in that you paid too much and you should definitely sell it. But I'll never say that again, and I'l stop being negative from now on. I know where you're coming from because when I was 19 I bought an RX3 for $1400, had no tools and knew nothing about cars as well. And that's a car I was diving into the deep end with because I knew no one who knew about rotaries, or even cars in general, and no internet existed for me back then. Similar to the above suggestion I bought a 1300cc 808 for $300 for learning on, spare panels etc, and drove that around mainly, while figuring out the RX3 and panel work (the RX3 was a beat up stock standard 12A automatic, fair bit of rust and couple of dents. Long term plan was 13B extend port and weber, with 5sp manual.) The 1300cc 808 was a piece of crap all over, mechanically and bodywise too, and I found a mint 808 1600cc for $900. Learnt to rebuild a motor on that 1600, heads, chucked on a 32/36 weber, tuning and all that crap. Stripped the 1300cc 808 of panels, interior and glass for spares and dumped the shell. Drove the 1600cc 808 while doing the 13B and 5spd on the RX3, and getting it painted in 2pac and the rest is history, (another 808 for more spares, a $1300 RX4 coupe, and a $700 929 coupe for spares, bridgeports, extend port turbos, etc) So been there, done that, started off with no tools and knowledge as well (no gurus or helpful dad or whatever), but doing it that way was an expensive education, lots of work paid to rotomotion. I'd do it all again because these cars are worth stupid money now, but wouldn't do it with a car that's not worth much and had PO problems.

I just finished reading all the posts in this thread, and the massive amounts of schadenfreude of everything in this thread, from wanting to convert power windows to manual, to the show-off nature, to the lack of knowledge is just what I needed to un-bummer my holiday season.

If you haven't thought of this already, you will need different exhaust bits in order to remove the turbo, generally at least the manifolds and downpipe(s?). Make sure you do your research and have appropriate parts on hand, preferably at junkyard prices. E: I should ask, is this car a twin-turbo setup or just a single?

Yes, I'm sure the experts you are consulting will be able to nail down exactly how likely a motor of unknown age and mileage which may or may not have been rebuilt and if it was how well or with what parts that is running an unknown CR with an unknown turbo controlled by unknown parts is to blow up.

Specific car forums are a great place to find out some minor bit of trivia for your car or to find a nicely spelled out how-to with pictures and such, but the people are terrible and when it comes to general automotive know how, I would trust the people in AI far more. Except the nerds saying to sell it. Yank the turbo off, drive it like a madman and have fun with it.

It will cost way more in parts to remove the turbo and return it to stock. Either keep the drat thing and start doing some actual research on the EFI system, or just cut your loving losses. Everyone, stop crying about "compression ratio is going to danger to manifold your engine." Times have changed, and with it, new technology and tuning theories. Stock 80s turbo cars with their low comp engines were that way because we didn't know any better. Nowadays, a high comp turbo setup is fairly common, and if done right, a beautiful thing. I tuned a 10.2:1 CR Volvo to run 24psi. I've worked on and tuned a 10.5:1 b16 Honda running 10psi. High comp turbos are awesome when it comes to off throttle response, transient response, and make great street cars. That's why I keep saying you need to check what you are running. Is it the stock efi? Turbo efi? Chipped box? Nistune? What injectors?

Adiabatic posted:Quoting for posterity. Well, I mean, how DO I check it? I've got the service manual, and it states about the E.C.C.S. and the Electronic Control System in the Engine Fuel/Emission Control part, and it mentions an EFI Relay. Do I need to check on the ECCS? Do I need to check the ECS? Do I need to check the relay? What part am I going to likely have to replace? Edit: While reviewing the manual, I found what MIGHT be the issue with it idling, since I'd imagine solenoid valves, if they are anything like they are in the Navy, are finicky sons of bitches, and there's a specific solenoid that "stabilizes idle speed when engine load is heavy". fishception fucked around with this message at 20:17 on Dec 25, 2014 |

Yeah, that's pretty normal. Increases RPM when the ac is on or you're wrenching on power steering (which loads up the engine and may cause stalling otherwise). It's the emissions control solenoids and any vacuum lines that can cause problems however.

So the solenoids your speaking of. Like the one I told you about at the back of your engine with a loose wire going to it im up for helping you out. but don't expect your turbo to become a non turbo in a few beers and a mig welder. I am willing to guide you in an appropriate direction and see if anything else obvious is hosed.

Motronic posted:I haven't seen anyone saying that. There has been a bunch of posts about how he should return it to stock (remove the turbo bits). I'm pretty sure the part numbers on the ecu are different between turbo and non-turbo models. Similarly the injectors should have parts numbers cast into the plastic upper part with part numbers as well. Googling that will tell you make and model they're from, or flow rates if they're aftermarket. If it has a nistune, it'll either have a connection to tune it, or if you remove the top cover, you'll see a daughter board. The reason it has idle issues is likely from the bov venting metered air, or being slightly open at idle.

I love the car. It's not a turbo, and was mostly unfucked by the two PO's that had it before me. I have done all the work on it myself and consider myself a pretty experienced shadetree mechanic. All that being said, you have no tools or previous working knowledge, run far away. Let me explain:  This is a stack of recepts for about $3-4000 dollars in parts that i've had to replace in the last 6 years to keep the car running. All done by me, no labor cost factored into that. This does not include the wrecked parts car that i also bought to pull parts from if needed. I'd advise you to sell it, buy a junker car that you don't care about, and ruin that by learning to work on cars. Don't ruin a Z trying to learn to work on cars, please.
