POST **** NOW ------!!!

 

THat z31 turbo is great for a b18. Worst case, just a rebuild can do the trick. it'S good for almost 300 HP!

but sure, there's lots of things we can do to it to furher improve it's behavior on a b18.

For a faster spool up but no more than 260 hp, and to have that standard 5 bolts outlet flange, you could switch to .48 a/r turbine and keep that z31 compressor side.

for more power without sacrifying much spool up, you could upgrade the compressor for a t4 and that way, you can do as much as 400 hp on the odd balled z31 stage 1, .63 turbine side.
