cheers lads, i thought i could use a compression plate to change the compression as opposed to gettin custom pistons, i heard that this was ok aslong as u don't use large boost. i was wonderin as my car currently has efi can i leave that on there or do i have to change to k-t mfi?

i have seen a fiest before that had a turbo conversion on a zetec and they just reprogrammed his current chip to increase the fuelling.

any thoughts on this?

cheers for ur help lads much appreciated im a novice im sure u can tell!
