Trd flywheel questions Anybody know ??

bodinejcs · 12-05-2007, 08:05 AM

I have a 1985 Mr2 20v with clutch problems , it started to slip the other day numerous times so I ripped it apart , this is Dave Spinettis old car , so I am not sure what cltch setup is in it . Supposedly it has a trd/hks lightened flywheel and a trd clutch / pp . After ripping it apart , it surely has a trd cover and clutch
disk and the flywheel looks aftermarket though I can not find a TRD marking on it . Well , after inspection , the disc actually has some meat still on it still , though the pp and the flywheel are pretty glazed , so I am not sure whats going on yet . It has a three puck trd kevlar clutch disk 200mm (7-7/8) for what its worth .
Also there seems to be a balance problem with something as the pressure plate has some crudely drilled holes on one side that I assume are for a balancing problem remedy , not sure . Anyway , do I have to use a TRD clutch set with this flywheel or can I mount a stock setup to it with no problems. I don't race the car , so basic fuctionality is only needed . Also , can you machine these types of flywheels and should I have it balanced due to the fact that it has those crudely drilled holes on the old PP . I don't know anything about these clutch setups , so please help me here if you can

Most likely you can just use a normal replacement 16v clutch and pressureplate. If it's 200mm, just get one for an 85 mr2. The pressureplate should boltup just the same.

If you want to ditch the trd flywheel, a flywheel from just about any A series motor will work. Just order the compatible clutch set.

Sounds like you got this car running and driving without too much issue.

Yeh , I have been driving it lot thanks to all your help in sorting it out , I appreciate that .
The flywheel has a little bit of step up from where the pressure plate mounts if you know what I mean . Will this throw off anything relating to the clutch travel , fork etc. What to you think about the crudly drilled holes in pp mount area , I know spinetti did this , it looks like he may have tried to balance it , but why would he need too ??

Maybe it would be a good idea just to get another flywheel? Just having a lightweight flywheel makes the car a bit less enjoyable for daily driving anyway. It's contributing to this "circus clutch" feel.

You could probably resell the trd flywheel to pay for a lot of this.

Well , I actually meant "circus clutch " as in the way it looked with all the crudly
drillled holes in the pressure plate , it looks like a hack put this clutch in this car.
It did work okay though and the light flywheel was never a problem to me , it drove very similiar to my 88 except the pedal was a little firmer . I ended up just mounting a stock clutch to it last night, it looks like it will work , I should have it finished up today and I will post my findings later . Thanks a bunch !!

I realize this post is a zillion years old, but yeah, that's my old car. It is a "TRD" flywheel, made from billet steel with and integral induction hardened ring gear (the step in the flywheel is stock). They don't get any better than that. I'll take it if you don't want it any more! I think HKS made them for TRD. The clutch and Cover are TRD units and were balanced as a set. Not by me but by TRD. those parts came out of one of my other toys and were done by TRD directly for racing, and the balance mattered.
