    Astra Coupe 2.2 engine mods?

    Ive pretty much finished modding the external of my car so now all thats left is tuning mods.

    What is there to do?

    Im thinking 2.4 inlet manifold
    Lightened flywheel
    sports cams
    remap

    Anything else i should be thinking of? and anyone recommend anyone to take on the work for me if i buy the parts?

    the 2.2's have 2 cats like the turbo models, ive heard that if you get a precat/decat and then a decent sports cat and cat back exhaust then it will transform the car

    i would get a larger air intake (like beesons on here in the classifieds) 2.4 mani and precatdecat full exhaust with either a 2nd decat or sports cat. high lift cams and remap. with the remap you can get a raised rev limit which will make the car sound the nuts! should be looking at good powaaa :P

    Thats a good start, but also add

    Piper or simlar exhasut manifold
    exhasut system, 2.25" bore if your not using cams or 2.5" if you are
    gas flowed head/skimmed head with increased compression to 11:1
    That should make 200bhp

    what he said ^^^

    there are better options than the 2.4 inlet. they tend to gain power high in the rev range and lose mid range torque

    If your serious about tuning ask atom x on z22se.co.uk
    This is evolution

    AtomX should rename himself Dr Frankstein as he builds MONSTER (engines)

    Your right about the 2.4 loosing power, but the options are very limited for 'off the shelf' bits
    The possible alternatives are Z20NET manifold (short runners, similar mounting points to the standard manifold & also made of alli)
    Dbilas (ive got on and it rocks!)
