THANK'S FOR YOUR ANSWERS!!!!!
In fact I choose to use the 215 mm flywheel, because with the 228mm you need to found a 911 (2.0 or 2.2) strater or one of an automatic gear-box bug (sorry for my english!!
).
And you have to modifi the clutch and the gear-box so too mutch work to winn.... Nothing because the 228 flywheel is too heavy ...
Any-way i informe you for my next modification
See you Olive D.D.K POWERED!!!!!
