    more power

    hi im gettin bord of my standrad power output of my mk4 gsi turbo now. i wanna achieve more acceleration and just more power really. ive been reading through the forums for hours now and everyone seems to be doin same things. but not knowing engines much im a bit stuck, so few questions really

    1. with the vxr turbo do u just bolt it on and then you get wat bhp and upgrade
    2. vxr injectors the same as b4 bolt on and away you go

    they seem the most used mods so wat else could i do r the stage kits from courteney good or regal better and wat stage/phase is best

    A cat back system with pre-cat replacement is recommended to get rid of the exhaust gasses more efficiently. I think a sports cat is only really needed for 280+.
    Also get a panel filter and the veccy C pipe fitted.

    Personally i wouldnt bother with a VXR turbo until your GSi one goes pop.
