Just fitted another one of the BBK 20G single scroll turbo to an un opened 03 sti, just running CAI, hyperflow TMIC, 3" TBE, big 5" 100cell cat, Non EL headers, inlet pipe, with the BBK 20G and went ......258kw at 6600, on 23psi, 23psi at 3700, peek torque at 3800. Talking vf34 spooling and GT30R power.
I did some more porting on the turbo, just matched it to the headers a little better, and opened up the comp outlet little cleaner, the 3"TBE is just a normal open mouth, splitter, with a 70mm diff back in it.

Do you stock a replacement BBK for a vf38 twin scroll? If so do you have a current compressor map handy for one of these or at least some specs?
I know from rexnet that BBK twin scrolls exist although i assumed these are for the vf36 / 37 equipped sti's and not the vf38 equipped liberty gt autos
Thanks
