Need step by step guide: OEM 4 spoke steering wheel swap to OEM 3 spoke

Hello, I have a 1994 300ZX TT with the 4 spoke airbag steering wheel, cruise control controls are on the stock, which I want to keep. I want to swap in a OEM Z32 3 spoke steering wheel with no cruise control buttons on it. Besides the 3 spoke steering wheel itself what exact parts do I need? Yes, I know I'm losing the driver side airbag. I want the cleanest result.

Need help making a decision, finance or patience

I’ve been looking for a Z31 for a while now, Ive always wanted one and after having gotten the opportunity to drive an 88 n/a manual, I want one more than ever. Unfortunately, because of my tendency to buy cheap cars up front and dump a fuck ton of money into them through out my ownership Im kindof stuck in a broke loop hole. Not broke to the point where my bank account is always at 10 bucks, but broke where saving up around 8 grand feels nearly impossible, if you get what I mean.
Because of this, Im heavily considering getting a loan for the nicest Z I can find. This isn’t my first experience with old cars, my first car was a rotted out EP3 SiR, second being a rotted out prelude. On top of that, I also have a 2012 mazda 3 that gets me where i need in the worst case scenarios. If I were to finance this Z, I would definitely sell off the prelude. (Civic was sent to the scrap a little while back)
The prelude is the main thing draining my cash at the moment, although I refuse to get rid of it and then saving up for a Z, I simply cant live without a “fun car”, Im sure some of you can understand this.
Anyways, I was hoping to get some advice from you guys on what I should do to get a Z, Ive been looking at prices slowly climb these past few years and Im getting pretty scared they’ll go past the 10k mark, which at that point the car will become another dream.
Thanks a lot to anyone who took the tome to read all of this.

Z32 300ZX at an auction 20 years ago. That aero wing sold me and I actually placed a bid,, but got outbid. Still hurts a bit, but at least I managed to snap some pics!

Good muffler?

Hello everyone!

My Z31 currently has a Flowmaster that the previous owner put on, but it's just plain too loud. It has good sound, but it's really droney between 2200-3000 RPM. Does anyone know mufflers that sound good still but are fairly quiet?

Buyers Regret on my Z

I’m honestly having some buyers regret with my Z32. I’ve had it like 3 months and it still runs decently (bad knock sensor) and like I’m willing to do repairs and everything, I definitely have the willpower to do these things and learn but I’m just so scared about discontinued parts. What happens if I encounter an issue that can only be fixed by discontinued parts? Has anyone ever ran into that situation and what did you do if you have?

Overpressurized fuel tank question

Went to fill up my tank the other day after a long hot drive and it spit some fuel out when I took the cap off. Everything looked fine on visual inspection, so I'm guessing clogged charcoal/carbon canister or a line somewhere. What's the best way to test the evap system? Pull vacuum from intake side, or pressurize each line one by one? How much pressure/vacuum? Noticed TT.net was down too, so I couldn't find a good guide.

Any Repair Advice?

Was my uncle's car before he died years ago and now my aunt wants help to fix it. I haven't set it up on bricks yet, but if y'all see any exterior things that need work, please comment, anything helps.

Anyone know what this sensor is for?

I'm putting the ac system in my 1987 300zx right now, the old owner had taken the entire system out. When I took the bumper off to get to the condenser, this little sensor thing fell out, it doesn't look like it was secured before. I can't seem to figure out where it goes or what it does.

Happy to officially be part of the group (and thanks for the advice)

just bought my first 300 and can’t wait to get it out on the road, after a mandatory timing belt replacement of course lol

is this saveable?

this is my z32 I was told it was dry stored when I brought it but not i have gotten it up on a lift properly that's looking unlikely.

​

its a jap import and I live in the UK so z32s atnt exactly common. its always been my dream car and ill do whatever I can to save it.

​

I have gotten in touch with some restoration places but tbh I'm just looking for someone to tell me they were in a similar position and it us savable. but if its not I would also like to know. better to be told now than sink endless money into a car that will never bo on the road, even if its my dream

​

thank you guys 🫡
