167 bhp iirc.

Hmm, that means the 2.5 omega runs different cams to the 2.5 vec. Wonder what the difference is between them. What is the standard output for a 2.5 omega, do you know?

the 2.5 omega is 167bhp (so about 185bhp with all 4 3.0 cams in)
the 3.0 is 207bhp
2.6 is 178/9bhp
3.2 is 213bhp and also 217bhp(dont ask)

urm it's g's and a's in the x30 and e's and f's or c's (not sure about that) in the x25 but the c25 has different cams on the gsi two g's and two e/f's

Yep, that's it. X25XE has different cams to C25XE which shares one set with the X30XE.

X25XE is 167BHP IIRC.

The 2.5 is exactly the same as the vec then. However, the vec GSi had the 3 litre Omega cams fitted and produces 190BHP or just over. Can't remember what else the vec GSi had but I know the biggest difference was the G cams.
What FPR does the Omega use, I know when I fitted a 4 bar it gave better response at wide throttle openings, never got the remap to take more advantage of it though

FPR is 3 BAR and there's plenty of injector flow so no need to up the fuel pressure IMHO.

i dont know, the vectras got a different intake system to the omega.
i put 185 because i dont want to get ahead of myself see and be too optamistic lol!

you take it upto about 200bhp with the 3.0 cams 4bar fpr and remap

Dont take that as gospel, may be me getting it wrong again. Thought it was A's and E or F's in vec but would have to check. The 167BHP you gave seems a bit too similar for the cams to be different.
