Hi all, is there a company that makes Connecting rods to lower the compression of the 2.0 Zetec E engine to 8:0 that work with the stock crank and pistons, or that can custom make them. ive been quoted around £1000 for them in the UK. although i do like to do things properly but £1000 is a bit steep.

Connecting Rods dont lower the compression the Pistons and the head CC basicly sets the compression ratio
There are 2 Rods out for the Zetec engine that is the same as what they call your Duratech E engine
Eagle and crower billet, I wouldnt use the eagle anything over 300

i know normally this is the case but the garage i use say that the pistons are very good its only the con rods and they sell custom made set that lowers the compression (ie just shorter),
Tom seems as you are the man in the know, if i were to go for 260BHP at the fly would you recommend lowering the compression or adjusting the timing and replacing any thing. we only have 98RON over here which is about the USA 92PON~
I really want 260BHP but wanna be sure i wont blow any thing.

If i were going through the trouble to to do rods i would loose the stock pistons as well, The stock pistons are weak around the ring glands
Lowering the pistons into the Cyl isnt a good way to lower compresson but it will work

Yeah, don't spend the money on a nice set of rods and then put stock pistons on them.
Did you get the PM I sent you about your other thread?

ok after looking at the diamond pistons they only come 9:0 on stock bore... will this be ok?
02-08-2005, 09:04 AM
I can get you diamonds that are 8.2 to 8.5 Compression or a full built short block as well ready to go

would the 8.2-8.5s work on stock bore?
02-09-2005, 03:03 PM
ok they got back to me today im buying custom made 8:0 diamond pistons and crower rods for $1350 including shipping to the UK thats £727.
Thanks again, for the great info.
