hi all looking at uping the power of me vectra 2.2 sri i would like 200bhp but not sure what would need to be done to reach this figure.
my plans
panel filter
4-1 manifold (where to get 1 from and how much?)
cat back exhaust
balance shaft removal (need new timing chain and a good service anyway)
lightened flywheel (clutch not got a lot left so uprated clutch aswell)
remap can it be remapped if so by who
what sort of power would that lot give me.
then i guess im onto porting and cams.
anymore info on whats good to do please let me no
thanks matt
