Updates: Vendor Posts and Be Nice to Each Other

26 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.

can't get the engine and transmission to completely mate

Post image
6 Upvotes

Picture isn't the best, but its the best I could get. Got the engine in with a crane, and we have the splines of the input shaft on the clutch, got them lined up by spinning the crank with a wrench while mounting the engine, but this is as far as it will go, and I dont want to use hard force if I don't have to. I'm assuming its just a very tight fit on the pilot bushing, which did fit on the transmission input shaft before installing it in the crank when I test fit it. Is it just this difficult to get the input shaft to enter the pilot bushing or am I doing something wrong? Any pointers are appreciated

EDIT: the pilot bushing also fit on the clutch alignment tool, which also fit in the engine with no issues and minimal force after the pilot bushing was installed.

Z31 Engine install

9 Upvotes

Hi guys,

So I’ve finally finished my engine rebuild and I am preparing to drop it in. For context, 1988 Nissan 300zx with automatic transmission. Now, we tried to install it with the transmission still in the car and it was a nightmare. Hour 5 realized that the torque converter wasn’t even in all the way. And even when we pushed it to what we thought was all the way in the engine refused to line up.

My Question is, do I just drop the trans and lower them both in is that easier or do I just keep trying to get them to line up?

Z32 How can I get a new key cut for my Z32? Having trouble getting a black key made

5 Upvotes

I have a 1993 300ZX and currently only have the OEM red valet key. I wanted to get a standard black key made, so I bought a blank and took it to two different locksmiths and two Nissan dealerships, but nobody has been able to cut it.

Both locksmiths told me their vice couldn’t properly grab or secure the valet key, so they couldn’t cut the new one? I’m not entirely sure what the issue is there.

I also tried two Nissan dealerships, but neither had records in their computer systems that went back to 1993, so they couldn’t help me either.

At this point, am I just unlucky with the places I’ve tried, or is getting a new key for these cars genuinely this difficult? What other options do I have?

Thanks!

Z31 1984 Z31 Engine Swap Recommendations

1 Upvotes

Hey guys! I'm picking up a new project car next week ('84 300zx), it's got all the parts minus the engine, I was wondering whether anyone had any suggestions for a good engine to throw in it? I was just gonna get another VG30E but I figure if I've already got the engine out I could throw something else in,

Anyone know a good engine that would fit without too much custom fab?

Z32 $12,900 88k miles (supposedly) Is this one worth it? What would you pay?

Hi, I found this clean looking Z32 local to me on fb marketplace, and I plan on taking a look at it but I don't know how do initiate. I dont have the experience so I dont know what to ask in my first message. It doesnt look bad, paint looks good, wheels are fine, and interior looks good. But there are no closeup pics. The seat covers are also kind of worrying. Here's the description.

Just seeing what offers id get. If its a good price i will sell it to you

Clean title

Everything runs great

No grinds

No trades

Mods:

Lowered on coilovers

Esr rims

Just shoot an offer

Wont respond to “is this available”

I don't know what a good price is, but I plan on having about 10-11k cash on hand and if it looks good after seeing it and going for a test drive. I'd like a good estimate on price because if they dont take the money I need to know how much I should be spending on this example. I will refer to the wiki for what to look at but if theres anything I need to emphasize, it would be cool to get a heads up.

What all should I ask in the message? I'll ask for some more pics, some of the dash and mileage to confirm miles.Any maintenance, and some engine bay pics. Is it worth 13k? Thoughts?

Help identify Z31 Engine Noise

2 Upvotes

Can someone help me identify what the ticking noise in the video is?

The ticking noise I am referring to in the video is pretty inconsistent as you can hear, where it almost seems to come and go. It does get faster with engine revs. Sounds like its coming from the front of the engine but hard to really say. Does not seem to go away once the engine is warm.

Hard to fully capture the noise on video but it is pretty loud in person. If i try to take the video right next to the motor with the hood open the ticking gets drowned out by the engine noise quite a bit and is ever harder to hear on video.

Car is a 1988 Z31 Turbo, Manual, 2+0, roughly 220,000 KM (136701 miles).

Any help would be appreciated! Thanks!

Z31 Z31 Turbo 2+2?

2 Upvotes

Saw one of these recently and found it interesting, not looking to buy but dreaming for the future. Been reading up, but have failed to find any information if the turbo models were offered as 2+2. Would love the second row just for easy access space in travel (backpacks, bags, etc), and have seen references to them but I wasn't sure if it was referencing Z32s. If there are some, how rare are they?

Whats the price range for a normal turbo Z31 that isn't in entirely garbage condition (aka rusting to pieces, can start, can run, can maybe drive, with issues) anyway? It seems like any used market has shifted drastically in the past 6 years.


r/300zx • • 3d ago

Z32 Thinking about producing these Plenum cover for the z32. Designed to cover the intake ports to prevent anything from falling into the engine during maintenance. Is this something you guys would be interested in?

Z32 Greddy profec b spec 2fitment

Downloaded and printed a mount for the Boost controller in the clock location. See link; https://www.thingiverse.com/thing:4294545. Has anyone made this fit? It seems almost 1" too long. I can't put the bezel back on without the mount hitting the supports under. Should I have been cutting the dash? Seems excessive..

Anyone have a better print I could use? It's currently in a bottom din slot but I'd rather have that free for a double din or storage.
