Hi guys...

Just after a straite yes/no answer, been doing some research and cant find what i need...

I have a R34GTT and im looking at buying a s/hand Excedy twin plate clutch from a R33 GTR. It is a pull type clutch, comes with replacement flywheel only

Will this bolt straite in and work or will i need a push pull convertor? Are the clutches the same size?

Any info you guys can give me would be great

Thanx

AT the moment the car is running stock turbo, the plans of a bigger turbo are on the cards for the near future though, so im planning ahead...

The clutch is cheap!! Under $500 thats why im looking at it

The R34 pull type clutch uses a 250mm plate so straight off the bat they are gonna hold more torque than the 240mm plate on the previous models. Unless you are going to be making more than 550hp at the wheels then you can get a really good brand new single plate from NPC for about the $900 mark or less and if you aren't going to go over 400hp at the wheels, an organic plate behind a slightly modified cover will suit you fine and they are $100 cheaper.

Is it worth buying the second hand stuff to suit a different model and possibly having issues just to save a couple of hundred?

It certainly won't save you any money if there is problems and you have to pay twice to have it fitted or fixed

Twin plate clutch on a std gtt, do it like everyone else does upgrade power and handling and wait for shit to break.

Upgrading the clutch first with a possible stuffed used twin plate is stupid.

I hear what your saying and thanks for your words of wisdom. The twin plate excedy to buy for my car is over $2k so if i can buy a s/hand one from a a different model for a quarter the price then i would be crazy not to give it a go if it was to work the same..

Im trying to find out as much as i can re: fittment to try work out if i have to mod anything to make it work and then i can see if its going to be cost efficient.

power wise i doubt the car wil see 500hp@wheels. plans are for a 35R on E85 around 20-25pound with some drop in sticks

Im not going to buy the clutch if its stuffed am I!!!

GT35R on 25 pound of boost and E85 is going to see 500 hp.

On the subject of buying a stuffed clutch - do you know what you are looking at? How are you going to tell if the plates are worn out or if they have X life left?

Then even if you know that, are you going to be able to tell if there is spline damage, a warped hub or a fragmenting friction material?

Just because something is is $2000 new and you can get it for $500, doesn't mean it's going to work well and the fact that it's 1/4 of the price would usually tell me that it needs rebuilding.....which is going to set you back about $800-900 anyway.

Exactly.

come back and ask the question again once youve done all of this ^^^^

cause you make it sound so easy... if your skimping on a new clutch but have these plans to a 35r you either dont know what your talking about or it will never happen anyways...

leave the 'twin plate' clutch till last, get a clutch that will handle stock power for now if your current once is dead...

you do realise for under 500hp you dont actually need a twin plate necessarily...

do some more research

Damm this has turned into a HATE fest!!

Excedy web site shows same part number for both applications, so that tells me it will work. Advise given re: it might need a rebuild... isn't that the risk we all take on buying second hand parts ???

I am also aware that a single will probly do the job, well it will do the job but i would rather just go hard on the clutch while im there, better to go over kill now then have to replace it again in 12 months when the car is making power as FYA would do!!

If i have to rebuild the clutch it will be as good as a brand new unit and still cheaper then buying brand new unit in the first place

Not a hate fest at all...

just dont understand, if your aiming to do things right the first time why but a used gtr clutch, why not get a decent new clutch to suit your car...?

after the conversion to make it fit and then the possible rebuild, you would of been better buying the right clutch first time round...

plus the fact the twin plate will suck with everything else std...

your simply doing it wrong...

FYA i think u need to read my post again....

The clutch is the right clutch for my car. There will be no conversion! Its the same part number so that means its the right part for the job.

The car has everything else done, just still running stock turbo. Will the setup i have now its making 270@wheels so I think the twin plate will be fine. It has a sprung centre so drivabilty for my weeker should be perfect.

Thanks all for your input

Question: Can I bolt an R33 GTR clutch to my R34 GTT RB25DET Neo and will it work?

Answer: Yes

Secondary answer: They are not the same. Even though Exedy may now sell them under the same part number, they have different release properties due to cylinder differences and the fact the GTR has a clutch booster, so you may get a shit pedal feel. Most people adjust it out but there is a tradeoff..

I will make a 50c bet that says the $500 pull type twin plate makes a better boat anchor than it does a clutch that will serve you well. Rebuild it - IF it's possible to and the damage is not too severe AND you have just outlayed $1300-$1400 when you could have just bought a proper single to do the job that will feel nicer, drive better and will be BRAND NEW for half the price.

I understand where you are coming from though, but out of every customer that walks in my door and presents me with a second hand part to fit, they have ended up needing to pay more than what it would have cost to do it properly the first time.

If you still want to get the secondhand twin plate, let me know coz I have a few old rear main seals and an alright looking spigot bush laying around somewhere.

Hey R33L,

I can relate very muchly to overenginnering everything you put into the car.

The confidence whilst driving that the machine is strong and nothing you are going to do will hurt it; makes me very happy.

I achieved this just by putting in an exedy heavy duty and the flywheel that went with it... It feels stronger than anything else in the car.

Then again i'm not making 270 :(

But if this part has come out of a 33gtr it could be more than a decade old... And You've

got more issues to worry about upcoming than just the clutch too.

By the time you've done 130,000 like My car has you'll have your synchros in the gearbox starting to wear out too. Mines having a recondition now.

Pain in the arse.

I have HKS GD max Twin Plate clutch and lightweight Flywheel for sale its only done max 500klm max to suit r34 GTT might suit others as well 32,33,34 GTRs,

took it out as I personally didn’t like it, it has that stock feeling very light but bitiey as hell .went back to single plate .

I have paid $2700 + shipping for this HKS twin plate clutch brand new

Will sell it for

$1300 firm

just to cover costs of my single plate ,

please let me know If your Interested PM me and I can send u some photos and measurements of how thick the discs are.

Fark no, please dont use a secondhand clutch plate, the bastard could have been tortured to the shithouse and caused damage that wouldnt be obvious till you have had it fitted to your car

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
