The 3.0 cams are a must. Exhaust manifolds would be next on the list, if money is tight I have seen a set made up using alfa v6 tubular manifolds reflanged

 

Is there another vauxhall flywheel that could be fitted? as ive read the std one is heavy (due to some countrys requiring the car to idle low to meet emissions standards)

Edit: Came across this: http://youtu.be/8sszT1aogUY

any info on it? (yes it will be big money, but looks very interesting none the less!)

the car in the vid is no more it was broke for parts! (i think)....there was doubts on the power figure of 327!, it was said that they were dipping the clutch on the rollers and getting fallse but impressive results!......i tried to get more info on the car but with no joy, apparently it was running standard internals aswell, and standard engine management, so 327bhp would be a huge gamble and a little less likely!......but as said who knows! lol

as for throrrle bodies mate have a read of this....
Vauxhall Vectra Owners Club - The Worlds Largest Vectra Community - Vectra A | Vectra B | Vectra C

and this

should be some good info in them for you! lol

 

i fitted a let flywheel to mine ,also running f28

 

best idea is to fit a c20xe flywheel and clutch, and a f20. will all bolt staight on. the v6's have a massive flywheel and real long winded gear ratios.

 

if its a gsi engine it will probably be an msd one so the 3.0 cams will make no difference

msd setup is what i'm running

 

Thanks guys, ill have a look at those links.

caprixpack - yes its an msd one (are these 200bhp std rather than 190 that eg a 2.5v6 sri would be?)

 

the gsi engines (MSD) are fitted with 'G' (3.0ltr) inlet cams and are 192bhp iirc as apposed to around 170bhp from a standard 2.5
