hi all im planning on running a turbo on a 1.8 16 valve silver top zetec engine. ive heard this can be done using decompression plates or skimming the pistons. does anyone know much about this job and how reliable it is. any help would be appreciated

i skimmed about 39 thou off my original (pre 95) pistons to lower comp, but a year later im still worrying about holing them, gonna get some forged ones myself. but as a guide i have run 14 psi (19 for a day!)with no probs (2ltr zvh t3 turbo). also the decompression plate would be cheaper & if i done it again (on the cheap!) i would take that route so as to leave more meat on the crowns.

cheers dude, what sort of managment were you running. im told that if you use the plate it can fcuk up the timing and stuff. im only planning to run about 14 psi max, dont wanna fork out for gearboxs and clutchs. im a bit of a tight arse haha. sorry for being dumb but whats 39 thou mean is that 39 thousands of a mllimetre 3.9mm?
cheers
