Hi folks,
I know there are plenty of threads on how to build a trans, but im finding that parts have gone out of production on certain things. Notably the 7/8" chain
my "plan" is to run a z3 turbo kit with the precision 6262 turbo on e85 etc making about 400-420whp
The idea would be to very ... VERY carefully run a stock HD trans while building another one on the side.
I know i would want to do the 300m input shaft.
My understanding is that the stock chain fails somewhere after 350? whp. I have been trying to source a 7/8 single chain, but it appears they are out of production now. I recall reading that the GXP chain is compatible and stronger.
A few questions:
1. Where do i source something like this
2. is it a double chain, or single?
3. will it hold 400whp
4. Can i just grab the trans from a GXP or v8 impalla?
5. What else do i need? Ive read that the flex plate potentially needs to be upgraded, and maybe the Torque converter? are there still good sources for these?
