Hi all,
Had a GTI MK4 couple of years ago which I sold for a Nissan 350Z, now that I need a 4 seater again, I came across an 02 MK4 GTI 1.8T originally tuned by ABT to 240bhp, all going well I'll be upgrading to a bigger turbo, stage 2 re map, stronger brakes and a new clutch if needed, while exterior will stay the same as the car already come with an ABT kit. As a general rule is there anything to look for ?
