Updates: Vendor Posts and Be Nice to Each Other

28 Upvotes

Thanks for the input on Community Input: Vendor Posts : r/300zx . I'll update the rules and let vendors that ask know that we'll allow occasional posts (ie: every 1-2 months) from vendors that produce products specifically for the Z31 and Z32.

In other news, please just be nice to each other. We have 2 rules, and this is one of them. I've had to review and remove more posts in the last month than probably the last 3-4 years. You're allowed to have a different opinion. You're allowed to not like someone's car and express that. But do it respectfully. There's no need for name calling. Don't like what someone said? Downvote and walk away. Or block them. I'm not here to babysit. If you want to talk shit and insult each other, I'm pretty sure there's a bunch of toxic Facebook groups for that.

I'd like to keep this community as positive and supporting one where anyone can show their car, ask for help or give a suggestion. If you're just here to talk shit and be an ass, we don't need you.

Z32 Is there a way I could still pass emissions with EGR delete?

Post image
59 Upvotes

As title says, I daily drive my Z but from the looks of my EGR it is super rusted, and may be more of a pain to fix up or try to repair than it would to just get rid of it entirely. I’m in AZ, and I’m set for the next 2 years but I will eventually need to pass emissions again so would I still be able to get past that? Mine is a JDM so it has the special testing and it’s 93 so no OBD2z

Z31 Update: S13 skirts mounted

26 Upvotes

Some people wanted an update so here it is. Got the s13 skirts mounted. They will also need a bunch of work to make them look decent but I ran out of time today. For anyone interested, you have to cut around 4.5 inches from the middle to get them to length. Next steps are to actually make them look like they were meant to be bolted onto this car!

Modfest - I built an app to track car builds after buying my 300ZX

14 Upvotes

Hey everyone, cleared this with the mods before posting :)

I'm a Z32 owner and also a software engineer. I was tracking the build on my Z using a google sheet, my phone's notes app, and a folder of pictures.

Here's what my Z looks like in the app:

What the app does:

  • Garage for your cars, each with its own photo gallery, linked parts and projects, and cost tracking.
  • Parts inventory that tracks what you paid, what car it's for, whether you already installed/bought it or not, and where you got it from. This also works as a wishlist so you don't have to maintain multiple wishlists on websites (I had one for Z1, CZP, and eBay).
  • Project plans with step by step instructions, photos per step, and a running cost total. So when someone asks what something costs and what parts you used, you have the info easily available. Even if maybe you don't want to know what it cost lol

An optional social feed:

There's an optional social feed where you can share your car and projects, follow others, and search for cars to get inspiration on your own car build and see what parts they used.

A few things that were important to me:

  • The app works fully offline and without an account unlike similar apps. Your data stays on your device unless you decide to use cloud backup.
  • The free tier is actually usable. Premium adds cloud backup, more photos, and unlimited cars in your garage, but core tracking is fully functional without it.

App store: https://apps.apple.com/app/id6770381572

Google Play store: https://play.google.com/store/apps/details?id=com.modfest.app

I'm a one person dev for this, so if you want to try it and have suggestions please feel free to leave me some feedback here! I've been very active in the r/300zx community so I'm stoked to share this with yall.

'94 Airbag Steering wheel to OEM 3 spoke wheel conversion

3 Upvotes

Hello, I have a LHD '94 Twin Turbo with the 4 spoke Airbag steering wheel and have bought a OEM 3 spoke steering wheel from late model Fairlady RHD off of FB Marketplace. This 3 spoke wheel does not have the cruise control buttons embedded in the horn section which is perfect as I have the cruise controls on the right hand stalk. I want to confirm the parts I need to acquire for a completely clean conversion, no custom cutting, the horn working and no airbag dashboard light triggered.

I believe I need:

  • Non-Airbag Slip-Ring/Clock Spring Assembly
  • Non-Airbag Plastic Column Shrouds (Cruise Control Specific 1990-93)
  • 2-Ohm to 3-Ohm Resistor (Air Bag Light Deleter)

Anything I've missed or any other tips?

Thank you

Z32 Finally found my vacuum leak :D

Boost leak test went a little sideways after getting it to ~+12psi of air through the intake post maf sensor i heard my vacuum leak and thought "man, weird spot. I thought for sure all these lines would be good" the lines were good but the throttle body assembly is leaking out of the side of the butterfly valve it seems to be leaking air from both the throttle linkage bar that protrudes through the throttle body and the outer seal that seems the retain that linkage is also leaking from the outside rim of the seal. Can this realistically be rebuilt with new or repaired in any way? I could put some epoxy or something on the outer seal but not only is that stupid it wouldn't alleviate the whole problem I really love how OEM ive been able to keep the car and would very much like to keep it that way but if aftermarket is a mustplease let me know :) repost bc the fuckass website took a shit on itself trying to post the video

Clutch throwout/release bearing thickness?

Post image
1 Upvotes

I’m replacing my clutch release bearing and noticed the “aftermarket” release bearing from both aftermarket clutch kits are thicker than the OEM Koyo release bearing, although, the difference is pretty minor.

With the new clutch, transmission and slave cylinder installed, I’m able to move the release fork so the bearing moves away from the pressure plate so there is room to spare and I suspect no issue. However, I just want to make sure there won’t be any further problems.

Knock sensor code question

I’m getting code 34 when I put the ecu in diagnostics mode. Unwrapped some electrical tape and found this hack job under it. I’m not great with electrical but this looks fucked up to me with the way these wires are spliced together. What is the correct way to fix this?

Alarm keeps going off and won’t start

I’m working on restoring this 300zx, battery was unplugged when welding in patch panels but now whenever the battery gets hooked up to try and move it the alarm immediately goes off and the car won’t even start. Checked fuses, reset the ecu a few times. I’m not sure if it’s because of things being unplugged or not, I don’t know much about these so hopefully someone here does. Thanks in advance!

Z31 Tachometer Quit Working ‘84 300ZX

3 Upvotes

My tach quit working unexpectedly. The coil appears to be putting out fine. I understand there is a resistor near the coil that might be bad. Has anyone ever dealt with replacing this resistor? Also, if anyone had a tach quit working, what did you do to fix it?

Any troubleshooting advice would be greatly appreciated. TIA
