Samurai 20V Posted March 14, 2011 Share Posted March 14, 2011 Came across a brand new one for sale, any opinions? Overkill for a BPU setup? Any body with any experience with these? How is the drive, is it driveable on an everyday basis? How about fitment? Complicated? Thks. Quote Link to comment Share on other sites More sharing options...
Nic Posted March 14, 2011 Share Posted March 14, 2011 Overkill at BPU power levels, for the best results ie. easiest to use and smoothest, always match your clutch to the power levels. There is no benefit fitting a clutch that can handle 700hp to a car with only 400hp, it'll just be heavy to use, grabby and noisy compared to a stock clutch. The stock clutch can handle BPU power levels, if you want something with a bit more bite then I'd suggest fitting a TRD clutch cover and disc. 31210-JA800 TRD Clutch Cover 31250-JA800 TRD Clutch Disc 90903-63001 Toyota Release Bearing 6spd Quote Link to comment Share on other sites More sharing options...

I have another question abt the flywheel, it is dual mass correct? On the Golfs and Audis the agents replace the flywheel when changing the clutch, how about the Supra? Is it recommended to change when changing clutch of is it a case of change if you need to? Quote Link to comment Share on other sites More sharing options...

On the Golfs and Audis the agents replace the flywheel when changing the clutch, how about the Supra? Is it recommended to change when changing clutch of is it a case of change if you need to? It is dual mass yes, it's not normally changed unless it's out of tolerance which is becoming more and more common as the cars are getting older. You won't know until the gearbox and clutch is removed though. We generally fit lightened flywheels when replacing them, some makes make some horrible noises though, best we've found so far are the Competition Clutch flywheels as they seem to be as quiet as stock.

Thanks Paul Thanks Paul.. Well my plan is to fit the TRD clutch and disc soon, I will have to check the condition of the flywheel when it is open. Will do some homework on the flywheels available here before I fit though.. Has the lightened flywheel proved effective on a Supra, particularly the BPUed ones?

Definitely yes, they can make it feel livelier and more responsive. Quote Link to comment Share on other sites More sharing options...

As Paul said you won't know if you needs a new flywheel until you are able to inspect it. I'd personally stick with the stock dual mass flywheel if running standard/TRD clutch, it does feel a bit livelier with a lightened flywheel, but it can also be a lot noisier.

Chris Wilson Posted March 15, 2011 Share Posted March 15, 2011 You could consider my uprated clutch, which is based on brand new OE parts with a stiffer diagphram spring set up. No judder (The HKS is like an on / off switch), light pedal and more than adequate for your torque. I have one in stock. More info below: 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 455 pounds plus VAT , 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 a lot of clutches damaged by people without the right gear (a ramp and transmission jack, plus correct circlip tools and fitment) or clutches fitted to patently *uggered flywheels. I will do a supply only if you feel competent to tackle the job or are using a bona fide garage to fit the clutch 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 + VAT for a new one, they look more like they should be over 500 to me, but don't say anything :-) The very similar LUK dual mass flywheel on Maseratis is nearly £1000 + VAT.... So if the flywheels old enough or abused enough to be scored it should be replaced. Fitting by myself will cost £175 + VAT. Reply privately if interested please.

Samurai 20V Posted March 15, 2011 Author Share Posted March 15, 2011 Thanks Chris.. I am in Japan, so will check out the prices here before I decide... Thanks to all for the help.. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 15, 2011 Share Posted March 15, 2011 No worries, given shipping costs ,not to mention transport uncertainties, and the current unfortunate conditions over there, I would say a locally sourced TRD one might be the best answer. Hope all is well with you. Quote Link to comment Share on other sites More sharing options...

Hope all is well with you. At the moment all is ok as I am far from the affected areas. I am keeping a close watch on the radiation threat, 1st sign of risk, I am on a plane back to SA. Need to check with my man in TRD if they are ok to supply as they are in Tokyo which is still suffering some transport issues. Thanks for the concern.
