Aren't much specs on the turbo, but for 23yrs old it is in excellent cond. converted to ext wastegate in stead of internal which is 14psi.
Set up built for quick spool up. xs power manifold. and ported cast for when that one breaks. tial wg and bov. dsm 450, 2 1/4 intercooler piping, johnny racecar intercooler. Started to tune with Crome pro. Gain 30whp in 3 pulls and a 11.5 afr the whole way. Still conservative on the timing too.
Is that the 4 or the 5 IHI.
I got the on off the auto. Its a bit smaller. But Im more interested in off idle boost than waiting for it to spool.
