I'm new to this part of the forum so I'm not sure where this post would go, mods please move this post if need be.

I have an set of Cosworth WRC Zetec piston and I was told the compression is 8.5.1 is this true?

Will these piston fit into an WRC CGI block?

If so then where can I find the WRC Zetec rods and crank shaft from????
If not then I need to sell these

 

BUMP
I needs answers

 

Have you called Cosworth ?

 

Hello, try putting this post in the focus section, it might get noticed.
The pistons should fit a cgi zetec block as long as bore size is correct. Try mountune ,cosworth or burtons for the rest of your parts

 

What CR does a WRC CGi Egine run?


not 8:1


what is the part numbers?

 

I use this piston in cgi block on 8.1=1, Ian Howell supplied them, he may know the spec of piston as he did have some wrc stuff i think.
Tyr his old website area6 or areasix.
Cosworth may also supply you technical drawings for the piston. I know my bike uses cosworth pistons with offset pin with longer pankl rods, and I know Ian did use longer rods in some engines.

 

it wasnt a question but a statment. WRC engine does not run at 8.1
