2.2 sri engine mods

[no2lurch]

on my w reg 2.2 sri, i was wondering what can i do to the engine to give it a little extra go. i was thinking k&n filter, but what else? can the throttle body be changed? is it worth putting an oil catch tank on it to help it breath better? anything else?

another thoguht i had was can the injectors be uprated?

Bit limited really especially as no-one will have produced perfomance parts as the market is too small. A K&N filter might perk up the throttle response (but create induction roar - maybe you want that anyway?) an exhaust system will be very loud and annoying but may increase throttle response (questionable extra bhps on n/a engines) some engines lose torque when fitted with exhaust tubing which is too large in diameter (done that myself with the Honda).

Otherwise there is a chip available and I think turbolag on here has looked into this and maybe had it done? I think it takes it from 170bhp to 180? something like that?
