Ok I am doing a built Y8 swap into my 91 Si. My question is what will fit off my Si onto the Y8 block. I know the intake and exhaust manis will. What about starter, alternator, water pump. All these are new on my A6 so don't want to buy new ones again if I don't have to.

Also should I go ahead and replace my clutch while I'm at it? Mine does fine but after boost it will probably slip I assume. Before I boost though I am going to purchase a new axle and tranny (since mine grinds 2 & 3 gear) so will it be just as easy to replace it then?
