I'm currently trying to "mate" a Toyota/Lexus 1UZ-FE to an Audi/Skoda 01E transaxle.

Custom flywheel, adaptor plate etc.

I have two options for the clutch however, either a sprung disc or an unsprung disc. Both are "OEM" fitment with the "same" gearbox but in different models/with different engines

My thoughts are that the "original" flywheel with the un-sprung disc would have been a DMF and hence it didn't need springs, I can't tell what the RS4 etc actually has as the pictures are all "indicative" but the 2.5TDI one I have was sprung and I'm guessing that the 3.0TDI would be as well (which is shared with the RS4).

So as I'm going for a solid flywheel I think should go for a sprung disc.

Anyone have any sage advice on the subject?

I don't like the idea of modifying the bolt holes....

I've already got a flywheel anyway smile
