should be machined off the top of a 1.8 zetec pistion when doing a ze-vh conversion ???

me and a couple of the lads have been talking about this and cant seem to find a definative answer ?

motor in question is a rs1800 bottom end if theres any difference

not asking u to post on wether i should do this and the relaibility
issues , cos in a perfect world we would all have new coswrth pistons to drop in


so just looking for how much to machine off ???

thanks peeps

rant over lol

 

a gut who was featured in FF a while back had a red Fez RST, i sold him 2 1.8 bottom ends before i started working at FF and he said he skims 1mm off the pistons and has run about 250bhp and 14psi on his for ages with no probs.

 

i purchased a conversion kit from mr howell and in the instructions it said to machine them by 35 thou

 

anyone else ??? still no certain answer ??
