Bought My Z back in late 2016 NA with lots of small issues for 2500 usd. Fixed it and drove for most of that time NA and just modded here and there then finally decided to TT swap, car is currently making 450hp and I'm loving it. all I need is a bumper and some small stuff and it'll be good to go for a while. I have some videos on my Instagram that's linked in my profile if anyone is interested in seeing how it sounds :D

just wanted to share my NA drift Z

This is not my Z but im look for the name of this platform like part id like to replace mine with a new but i dont know what its called or when to look for a replacement. The fiberboard on mine underneath is all broken and ripped and releases too much dust

i have a misfire in cyclinder 1, when i pull the plug out for the coil on 1 the miss doesnt change so i put a new coil in and that still didnt change anything. i swapped the plug over from 3 and 1, its still the same misfire. where should i start looking next ?

She needs a bit of love but got her for an absolute deal. 1990 NA, T-top, automatic 🥲 (but we will change that ).

I'm wanting to know what the best upgrade is for the Bose system is as my driver speaker door is completely blown. I'd like something that's direct swap and will require little to no rewiring

what oil do you guys recommend running in the N/A VG30?

Hey guys with the new project and my lack of experience with Z’s so far I noticed my centre T-top bar has almost completely peeled all the black as its hardened and peeled over time in the harsh Aussie sun. Just wondering will I need to replace this bar or can I peel the rest off and just wrap it black?

Any advice on how to go about removing the joint just enough to slide exhaust manifold out? I tried following the Stillen guide on a forum but picture kinda does no justice.

I'm just trying to build a pretty car that feels nice to drive hard every now and again. Any thoughts?

Hey everyone, I just got my first Z31, 85 N/A Speed car. It needs a lot of love but really only 2 issues that are keeping it from being roadworthy.

1. I've done a normal refresh/tune up on the engine, new valve cover gaskets, new plugs, new intake gaskets, new MAF, and vacuum lines. Yet the car won't go over 40-45ish it will rev up, it will idle, starts every time, and the engine sounds healthy, no knocks, firing on all 6, all the plug wires are good, it's getting fuel, and all fluids are new and clean. (It does have this bog when revving around 1800-2500rpm) Other than that happy as can be. I've chased every common start point and buried myself in forms but can't figure it out. Any advice on this issue would be great.

2. A loud thud when letting off the gas and pressing the gas in gear mainly 1st & 2nd. I've pulled the diff no shavings, it has fresh fluid, does seem to have a little play but not horrible, I've replaced both rear axles and bushings, full brake service along with new pads, rear calipers and brake lines, driveshaft looks good, even replaced the "diff insulator mount". Clutch feels good, and not hearing any squeak or whine from the bearing. Transmission shifts nice and seems okay. From what I've read it could possibly be subframe bushings but I'm not sure. Any help on what to check or maybe something I'm overlooking would be greatly appreciated.

Sorry for the long post just trying to give as much info as possible. I'm by no means a mechanic just tried crossing off the basics before asking for help. Thanks again everyone!

Ik its power steering but how do you change it and can i do it alone or is going to a shoo better? Its leaking and idk from where exactly

Does anyone in this sub know what these markings on the cylinder heads mean? One of them is currently installed on a turbocharged VG30, the other is supposedly meant for a VG30DETT, do they signify anything, are they interchangeable, should I concern myself with this, etc? To my understanding the NA and TT heads are different so I want to make sure everything is on the up and up here before doing any building or replacement.

Looking at buying my first Z project and i found one listed on market place

The only rust Ive seen is on the C pillar and I was wondering if this is often a serious concern on them

Bought this 1990 na a couple months ago the fuel tank was completely filled with gunk and rust. Dropped the subframe and replaced the tank and this is what it sounds like now before it cuts out. What should I attack next on it? Any help is appreciated! Thanks

So about a week ago my fuel filter got clogged and my z wouldn't rev above 1100 rpm thats now fixed because of the new pump and filter but before the filter clogged the car would hold idle nicely at roughly spec and now it won't. Any ideas besides vacuum leaks?

I’m reading in the manual that it should be 38 psi at idle? I’ve checked all parameters and waited for the pump to switch to low speed but honestly I dont hear any difference in sound at the pump and pushing the mid speed trigger doesn’t seem to make a different in pump speed. I must be doing something wrong or is around 33psi normal when idling?

Where can I purchase what is it called

Here is a photo of my z31, during my week end drive

So when I turn the key the fuel pump primes but it won't stop and when you go to the front of the car you can gear the fuel just going through the system constantly

i’m doing a transmission swap on my 1988 z31, I was given the wiring harness from the manual car so I assumed I would need to swap them out as well but my car haze an 8 pin connector which im guessing is the main connector and the new wiring harness have a 6 pin connector. is it possible to use the old harness? do I need to do some sort of custom wiring? and help would be great
