cheapness is all i can think of...

if your going to do it you may as well do it right first time tho tbh!!!

i was told they were c20let ones when i brought them (bascially got ripped off) just found out browsing though pictures that they are in fact the early xe ones, found out after the engine was built, anyway the compression is too high, so i need to know the deck height, its a standard block, with standard silver top rods machined for xe pistons, if anyone knows that would be a great help...

no idea, but you've answered your own question really, this is the reason i turned down a set for £20.

the XE pistons are forged and can take some hammer, but the problem u have is in an XE engine with turbo rods vaux people get away with runing big boost for some reason

but cause there in a zetec they wont be same,
and u NEED to check somthing, cause very zetec turbo ive had to strip down from a failure for people doing cheap conversions vauxhall pistons spin them selfs on the little end! and the little end bearing is always tight in the rod, if that makes sense,
ive seen no end of oval gudgeon pin holes in pistons because of this,

if it has been prepper propperly mate and engine built and the above mentioned was sorted, then just run it high comp, make sure u use a focus RS head gasket, some ARP's and dont skimp on having a MAP done u could have alittle poket rocket as high comp turbos = no lag, lotts of fun!!!

jus a pig to map and dont expect BIG power, but plenty of torque
