I did a bit of research and just wanted to make sure that the flywheel, pressure plate, starter, etc..from the A6(89 Si) will work on a Z6.
From what I read, as long as the transmission is 1989+, the 20 spline flywheel, PP and clutch will work on the Z6 block.

 

i used all that stuff on my z6 came off 90 civic si swapped the front water outlet too so its at the right angle for the upper rad hose

 

ok good to know. I'm sourcing parts right now. Just want to make sure I get all the right parts the first time.
thanks for the response.
