this is my effort, suszuki GSXR tb's on a 2.0l, although i never had them 100% set-up they were making at least 170bhp

spec:

2.0l zetec
Kent cams
skimmed head and block
focus rs headgasket
45mm GSXR throttle bodies
Saph cos blue injectors
vauxhall fuel rail
focus ST170 4-2-1 manifold
SECS S8 management





i then sold them to a mate with similar spec engine, but OMEX management and he cracked 192 bhp
