Basically iv got some c20xe pistons in my shed, was hoping to get my engine bored out to 86mm to accept them.

Any1 ever used them?? do the need machining down to get the correct c/r?
Iv bin told that they have a c/r of 7:5:1 once fitted.

Was going to get standard rods machined to suit the gudgeon pins and use arp bolts.

Any help will be much appreciated.

yes people use them alot, good piston,dont need skimming to lower the cr

the LET ones have a compression ratio of 7.5:1 the XE ones are higher.

iv bin told its the LET 1's av the wrong c/r, as there ideal for zetec turbo and the XE's have the correct 7:5:1. just asked this to make sure as iv msg'd company bout boring my block out.

yes i have them in my zvh. they dont need skimming they give you the correct c/r you need to run a good boost application.

JamesR1

ah yeah your right sorry my mistake, yes the LET ones give correct cr on zetec turbo. the xe ones are right for the zvh sorry i mis read it

thats good then any1 know how much it cost to get it bored out?? zetec rods machined to fit xe pistons and block decked?!?

drsrst2zvh

I Paid £440 for everything. New pistons, little ends honed out, block boring and refaced. and the ARP Bolts modified. Mates Rates!!!

oh that aint to bad then. well im takin block to my m8 2moz so he can strip in then he's gonna send it to a well known company in leicester and get it all done for me (hopefully can get that done m8's rates lol as he had his done there) then he can build it for me when he's got it back.... think its £120 to be bored out, £20 per piston to be machined then dunno how much it'll cost to be decked. that good price???

drsrst2zvh

I paid £25 per cylinder for boring, the pistons were £57 each, having the little ends honed to fit was £20, block decked was £40, then having th pistons modified for the oil spray jets was £10 per piston. My block had already had the oil galleries blocked off and the water pump and tensioner conversion done to it previously. Where abouts are you mate? Can't see your avator as on my phone.

danielson04

im from leicester mate. that aint to badly priced then i reckon. took engine to my m8s earlier so he's gonna get it sent off on thursday. he's building the engine for me you see (for free as he owes me alot of favours lol) so your lookin at bout £200 for it all then im happy with that

guys what can this spec zvh handle power wise

drsrst2zvh

The standard crank and rods are good for 300bhp. What do you have in mind?
