I'm about to make a one piece tailshaft for a 32 gtst with a gtr box (converted to rwd) and std 32 gtst diff that's making 500rwhp.
The GTR flange uses 75mm OD pipe( where its welded), while the 32 diff flange uses 65mm OD pipe (where it's welded).
What diameter pipe is best suited? any bigger than 3" pipe would have clearance issues.
How thick does the pipe have to be for this kind of power?
And whats the best method of stepping down the diameter of the pipe to suit the smaller R32 gtst diff flange?
A pic explains it clearer, currently using a shortened RB20 tailshaft.
