    The Z22 xan be supercharged, courtney vx kit for around £3000 !! It does
    take it toaround 260bhp tho...

    Smooth the TB, 2.4 inlet canbe purchased, remove the Pre cat....

    Think this canbe done to the Vec B, will unleash a few extra Ponies !!

    I think the stuff listed above is for the Z22SE engine.
    I believe there is a remap available for the Z22YH, IIRC an I500 owner on here had it done. HTH

    Not for the YH mate. Yes the 2.2 can be supercharged but only on the SE and not in the Vec C unless you get a stand alone ECU and spent 1000's just to get round the canbus. Throttle bodies are also available, but again not on the Vec C.

    The YH manifold is of the variable flow type so again the 2.4 inlet is a no no i'm afraid as its only a direct replacement for the SE. Port and Polishing the inlet is however an option. The 2.4 TB will not run but the 2.0SC tb from the US can be made to work on the SE but never tried on the YH. TBH, your looking at a Cat back system, sports cat, Piper zorst manifold, custom down pipe, Landrover one fits and only really a good filter on the inlet side. Tie all this in with a Map and you might see 170 bhp+, but the map will really help drivability. Adding cams will see you nearer the 180 mark at a guess, but to the detriment of the drivability. HTH

    One of the many times it's probably cheaper to just go and buy a more powerful car...

    Curious whether a nitrous system would fallfoul of canbus. If not it may be a serious option for the YH.
