A question came up regarding what is the correct flex plate for a turbo buick.
There are at least 4 different flex plates for the buick v6.

1) 86/87 Turbo 3.8
2) non-turbo 3.8
3) 4.1 non-turbo
4) neutral balance after market

I'm in the process of testing all of these and posting the results. Stay tuned if your interested!!
I finished the neutral and the 4.1 and will post the others when done.

The first pic is of a Lightweight version of a JW internel balance flexplate. JW makes a standard version of that flexplate and external balance flexplate. Also out there are the overseas versions (Cat etc).
