My suggestion has a backwards motor, slightly slanted. Mated to the trans easier, you see.. even if replacing the belts confuses the gently caress out of anyone not privvy.

Also, if he gets old enough, it is an oil (only) cooled turbo..

Okay, so it's quite a nice looking car. Way more powerful than I expected.








Hood pins!










Custom hood prop









It's got a couple of problems from what I saw:
- One of the belts/pulleys squeals sometimes
- Problems idling. The engine will sometimes stop running when you take your foot off the clutch. Idle RPMs bounce up and down a little bit.
- Weak clutch. In third, I was able to make the clutch slip pretty dramatically.
- Dash switch that controls the radiator fan. We definitely need to get a thermal switch wired up.

Fortunately for winter driving, it has massive turbo lag. It's really easy to drive sedately. We went to Autozone and picked up a set of battery terminals like kastein recommended (I picked up a pair for myself). I'm going to order some crimp-on ring terminals, then I'll head over with a crimper and we'll get his battery buttoned up.

I haven't uploaded the video of Mr. Firecock driving yet because there's a cat sleeping on my arm and a wife sleeping on my leg. I'll try to take care of that later tonight. My critique is that he's afraid of the friction zone, so he revs the car really high and then jerks his foot off the clutch. We did a small reverse burnout in the Autozone parking lot. I explained to him how clutches work, and suggested he find a big parking lot and practice making the car roll without using the gas.

yeah that was exactly what it was like when I drove it. my big rear end boots accidentaly held the gas pedal and I thought that was the cause of the squeaking belt. But this was also before the mechanic "Replaced it" so it could be the belt they didn't replace for you is now squeaking. If you can drive that thing to by my house at a location I will PM you. I can look at it sometime tomorrow during the day??? just pm me

Edit: after further review of the pictures and me not being outside in the freezing wind I realize your missing a mechanical fan. And im guessing the PO removed it in order to have that hella sick turbo pipe run across the front of the engine. WE NEED TO GO JUNKYARDING!!!!!

If I dint suck at Photoshop I could circle things but Ill just try to explain. SO first the belt in the rear of this picture looks old the one on the front looks new due to the paint not being poo poo. Also those four bolts on the pulley should be holding a mechanical fan to that water pump. And the little relay that is ziptied has the wires all twisted like some P.O. Fuckery so if your fans are electric that may help control them.

That fan setup looks better than I thought it would but I would still it for an OEM fan/clutch unless there was a thermoswitch on it.

However, I am not sure what the clearance is going to be like with that pipe there. Where is it going? The turbo and all the plumbing should be on the drivers side. Does it have an intercooler?

Safety Dance posted:

That should be easy enough to track down. The PS pump is the thing driven with the belt closest to the rad. These cars were infamous for bad racks which, gone unchecked, could eventually cause issues with the pump.

I'd make sure the belts are sized properly (not just length, width too).

Alternatively, the thing is almost 30 years old and the belt sheaves/pulleys could certainly be worn, or you know, bearings.

Did it stumble or run rough like a vacuum leak? OP really needs to get the manual and learn how to run codes on the old ECU though. It's not difficult.

quote:

That's not terribly difficult but beyond the OPs reach based on what he's saying. OP will want to be careful on the clutch so you don't start hurting the flywheel with it slipping all the time.

I am glad that there doesn't seem to be an actual overheating issue other than the fan.

I would be curious to know if this car started life as a Turbo or was converted. The "3000" on the intake plenum cover is actually the cover they used on the non-turbo models, although it's possible he just swapped it for some reason.

Yeah looks like even if he did put a mech fan back in it wouldn't work with that piping in the way.

Or just re route the piping....That's what I'd do or get a better E fan if that one isn't sufficient.

It does have an intercooler.

Honestly, I can't diagnose the idling issue very well. My first thought was "idle air control valve", but I don't know enough about Z cars to know if this one would have one.

That is a sharp looking car.

Quite a few issues from what I can see.

First, the car is still running the factory efi. There is a few issues with this, the open to atmosphere bov would cause running issues, especially on a clutch in. Second, the AFM is just passed a bend, which can cause turbulence and as such, poor running. Also the filter is right behind the fans, further causing turbulence. Look up z32 flower pot mod. The z32 had a huge issue with turbulent flow at the maf when cone filters are added, causing all sorts of weird running issues.

There is also an alarming amount of chinesium parts on it. The "nitrous" brand gauges are harbor freight/eBay, the fuel pressure regulator is also an eBay unit.

Stock z31 turbos are not very fast, I'm pretty sure this is an NA-T car, since all the gauges have been replaced and the top plate on the engine isn't the right one. The turbo clutches can also hold a pretty decent amount of power, this is probably running the stock NA clutch. These cars done right are very quick.

The biggest issues I have with this car is the fueling. If it is not running the turbo efi and upgraded injectors, the motor is not long for this world. Hell, I would hope it has been chipped or nistuned for reliabilities sake, but the cost to do that easily eclipses the cost of all those Chinese parts.

In all honesty OP, sell the car. You are multiple levels outside your capabilities. If that's not an option, it is time for a beater and a lot of time doing research and unfucking the cheap PO's doing.

That weird thing on the core support with the cheap looking metal bracket is a thermostatic relay. It is sold at parts stores but shouldn't be used for directly powering OEM fans due to crap current capacity. It has probably burnt out which is why you have to use the switch to control it. I prefer the Hayden 3647 ( I think that's the number) as it has a replaceable automotive relay on it. Also sold at all parts stores.

I wouldn't go quite that far. Yes, there's a buttload of PO fuckery, but Firecock told me he'd be willing to dump about $5K into getting this car running well once he starts working. Reading the plugs would tell us if the fuelling is way off. Once that's sorted and he has a new clutch in place, then it would be pretty good.

The original EFI is a really good point, especially with it likely not being factory Turbo car. This can be confirmed with the VIN.

A really nice unmolested Z31 is a decent enough car but not really super reliable, and to be honest wasn't super reliable even when brand new. Nissan was definitely below Toyota and Honda in the day. I question if this thing would ever be a reliable DD without non insignificant investment.

Cutting losses is not a crazy thing to do.

He'd be better off putting 5k into something else honestly. I'd get it running halfway decent and sell it. Then buy a Miata :v:

I don't think $5K would do it, especially if he has to pay people to do a lot of it. The clutch alone is not a $500 job at a shop, it'll be closer to $1k, and that wouldn't have done a thing to make it more reliable.

If the PO did convert a NA motor in a Turbo, I'd be really curious to know what he did to the internals, in particular pistons and compression.

Cutting losses is a reasonable course of action. He isn't comfortable working let alone have the knowledge. It'll always be parked.

Those pants are the ugliest pants I could find on short notice.

Now, to address everyone saying to cut my losses and sell it:

I'd really rather not do that. This car feels like something special, like something that I want to keep and cherish and have fun with.

I understand that it has issues, and I pretty much came into this car expecting to have issues, and having to resolve those issues. If I didn't think it had issues, it'd probably be a catastrophically boring car, and that is exactly the kind of car I don't want.

I get kind of a perverse thrill out of, "oh god the car's not working again, what's wrong with it this time".

[edit] It's admirable that you want to deal with the car's issues, but what we're saying is unless you have the knowledge to do it yourself you might as well be flushing money down the toilet. If you plan on learning on the car, and committed to do what it takes then go for it, but if you have any reservations about the task at hand whatsoever, you really need to cut your losses or it will end in tears and the car being worth less than what you paid for it after draining your account to get it to run and drive like it should.

If you're serious about wanting to keep the car, get the cheapest, worst beater that won't leave you stranded, unless you're OK with not having a car while you learn how to do something on. This isn't the best car to learn on, but neither was most people's first project car. Just treat it like a growth experience and be careful, if you're capable of following directions and can reason about problems, you can do anything that you want to that doesn't require tools you don't have; then you just need to get the tools.

Good advice.

I'm partial to the HF racing jack with the two wheels up from. The one with the steam roller front seems quite unstable when I used it.

If you plan on going ahead with this car, keep in mind that $5k will not do much if you're going to pay a shop to work on it (if a shop even agrees to work on it). $5k will go drat far if you're doing the work yourself and do things right (or else end up doing them twice).

The fact that it is still running means you have a decent base, it's just so much easier to learn when you're doing the mods yourself, not dealing with someone's half done project. Good luck to you.
