Clutch kits for r33 gtst with r34 gtt trans and trans problem?

Hello, I swapped a r34 gtt trans into my s2 r33 gtst and I'm looking into clutch kits to use. I bought a r34 gtr clutch kit before and the flywheel was too big so the trans fork would rub onto the pressure plate like in the pic (we used grease to see if it rubbed when tightening bellhousing).

What clutch kit can I buy for the car? The only clutch I find for r34 gtt is the Exedy twin which seems the best for street ability in my 500bhp skyline but  it looks sketchy from future motorsports.

I see different information whether different clutch kits fit different models but I don't want to mess up and buying a wrong clutch kit because some of these distributers are a PAIN to deal with since they don't answer any of my questions.

I'm currently running a spec pull type clutch kit but my tuner says to replace it with a twin disc. It does a grind from a ton from 3rd to 4th at high rpm. I'm not sure if that's why he has said to replace it? Tuner said the clutch needed replacing after dyno'ing the car. Could it be a synchro? I bought the r34 gtt trans new and it has less than 10k km on it. I had a shady tuner and I'm transferring to the big skyline tuner in florida east coast next week.

Thanks guys

I'm currently going the path of replacing my R33 gearbox with a new R34 unit, and believe these are the parts you need:

Item Details
Gearbox 32010-AA520
Gearbox Front Cover Assembly (Including Input Shaft Seal, pivot ball) 32110-05U11
Gearbox Front Cover Gasket 32112-05U12
Clutch Release Bearing 30502-69F1A
Clutch Release Bearing Carrier 30501-S0284
Clutch Fork (Including Clip) 30531-P0151
Clutch Release Bearing Carrier Clip 30514-14600
Clutch Fork Dust Boot 30542-69F00
Slave cylinder 30620-21U23

BYO push type clutch, tap the gearbox as described above, and change everything out. I've yet to go through the process though, so can't confirm that the information above is 100% correct. Make sure you do your own research to confirm the part numbers.

 

Edit: You also need to swap the lower gear shifter bush to the smaller R34 type. It's either part number 32861-H7301 or 32861-01G00, but from memory it's the first one.

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.

      Regardless of neglect or incompetence, fixing either is tedious and annoying. Most of the neglect on my car is definitely rust. I hope I can at least pass inspections later on and they won't fail the car due to slightly corroded hardlines. I was generous with rust converter and wax and it looks ok, most lines in the rear are hard to see properly anyways.  Definitely will test them though to make sure they don't rupture under pressure, in that case the car isn't going anywhere this year.
