installing cams and a head polish with a remap will yeild what, 30 - 40 bhp
£1500 for a 1.8T with half as many miles, 180 bhp standard, have i read that right that includes the engine? if it does thats a good price for a full conversion!
add a stage 1 remap you'd have 210+, then start adding breathing mods, air filter / full exhaust and you'd be getting nearer 230 bhp.....
i know what id be doing
