Im aware theyre different things fella! Also depends on time and how you go about sourcing parts, I did my corsa with new everything on the road for about 700 quid, but it took time!

If lexus specced a clutch for 300bhp however i wouldnt be surprised if it was ok at 400 provided you dont go for big ugly midrange spikes or anything.

As for ryans comment, I also agree 100%, there was a recent discussion on locostbuilders about transmission swaps etc and using something from the original manifacturer is always desireable. Just a shame audis transmission while strong is utterly wank for transplant due to sticking the engine out of the front of the car on anything small/light
