C20LET pistons
hi
i have a doubt.
in the fiestaturbo.com i saw information about conversions for turbo in this case zetec turbo.
my question is, can i use C20LET and the CR will be ok (CR- 7.4:1 is true) or i need to Skimmed the pistons?
what is the difference in C20LET and C20XE pistons? i know that C20LET is forged, but C20XE i dont know?
many thanks

The C20LET bore is 86mm, compared to the 2.0 Zetec's 84.8mm, so a slight overbore of the block is required. This presents no problem as the block is likely to have some wear on it and there is enough material to maintain the wall thickness. This will take the original 1998cc to 2045cc. Also required is modification to the rods to accept the 21mm wrist pin.
