You'd need the pistons aswell to get an SPi engine up to MPi power levels - higher compression ratio on MPi engine. It's cheaper and less hassle to find a complete C14SE engine than it is to convert an SPi :)

If your going to swap engines you may as well throw a 16v one in

Cheers for the replies.

The compression ratios are 9.6:1 and 10:1 will the pistons really need changing?

Agreeably, if i have to change the pistons, I may as well just stick 16vs on the top.
