ewizzy Posted January 20, 2005 Share Posted January 20, 2005 I am looking into getting a new OE clutch for my jap import Supra TT '93 I have been told buy a couple of places that the jap spec has a twin plate clutch as standard and for a patent part clutch its nearly £900!!!! What I need to know is....It the jap spec clutch same as the UK spec? Where is the best place to order it from and do I need to get anything else too? Something i remember reading tells me the flywheel needs something changing too? Thanks for your help guys!!! Link to comment Share on other sites More sharing options...

ewizzy Posted January 21, 2005 Author Share Posted January 21, 2005 Thankyou very much for your replay mate So, knowing that i can order any clutch UK or jap spec, Do I also need to order the bearing that goes in the flywheel too? and if I order a clutch kit from Toyota that comes with the release bearing and spring plate too? Sorry for so many questions newbie and all that! and I know I should Thanks again for any replies Alex Link to comment Share on other sites More sharing options...
MichaelG Posted January 21, 2005 Share Posted January 21, 2005 Tell them they are talking rot mate When i had my J-Spec TT a couple years back, the clutch went, i got a standard clutch plate, cover and release bearing all from Toyota and it wasnt more than £200 i dont think. I think it was like £180 odd but cant remember now. I certainly remember being pleasantly surprised at the price though My flywheel had a "heat spot" on it when i went to change the clutch but as i was selling the car i didnt bother with the flywheel. I think u only need to do that if its badly worn / scraped or distorted out of shape. Michael Link to comment Share on other sites More sharing options...

Chris Wilson Posted January 21, 2005 Share Posted January 21, 2005 I do an uprated, direct bolt in replacement for Jap and UK TT clutches, see below: Available now: Uprated MKIV TT clutches. I have instigated a few new performance parts for the MKIV Supra TT's. I will announce when things become available, but one which is available NOW is an uprated clutch assembly. I use the stock, brand new driven plate, as it is correctly balanced, doesn't judder and will hold all but mega torque highly modded engines or cars used for drag racing. I modify a stock brand new cover to give more clamping force. The reason I tooled up to do these is some of the aftermarket US clutches I have fitted SEEM to be built from used cover assemblies with reground friction surfaces, and a stronger spring. I have had hellish trouble getting these to fully release, because due to this seemingly thinner cast iron friction face, the geometry of the clutch goes to pot, and being a pull type clutch (the hydraulics pull the bearing away from the engine, rather than the more normal push type) it is a lot harder to effect a cure. For 425 pounds, no VAT to pay, you get a brand new driven plate, a brand new modded cover, and a brand new release bearing. I would rather fit myself so any complaints are down to me, I see too many clutches juddering due to someone without the right gear allowing the gearbox input shaft to bend the driven plateas the boxes' weight is allowed to swing on the plate centre, or clutches fitted to patently buggered flywheels. However, I might be persuaded to sell to people using bona fide fitters to install one. Toyota use a dual mass flywheel (the flywheel is in 2 parts, an inner and outer assembly, damped in the middle) which is now showing signs of wear causing a lot of rattle when idling or on very light throttle openings. For God knows what reason they are charging about 270 quid for a new one, they look more like they should be over 500 to me, but don't say anything :-) So if the flywheels old enough or abused enough to be scored it's best replaced. If pressed I will sell the clutch kit, which includes a new release bearing for a 3rd party to fit. Fitting by myself will cost 175. Both prices do not incur any VAT, I have a separate company for road car stuff, and it's not VAT registered. Reply privately if interested please.
