Does anybody here have any information about Escort Cosworths WRC engine.

I've been trying to find some info about the damn thing for past week and only thing i've come up with are that the stroke is same as "normal" Cosworth engine and that the compression ratio in 9,6:1.

I'm intrested mainly in connection rod lengt, piston compression height and volume of dome dish. But, any other info is wellcome too..

I'm building my second Cosworth engine. This time with slightly raised compression ratio, somewhere between 8,5:1 and 9:1. And slightly longer connection rods. I'm going to keep the standard stroke. Bore will be somewhere in 91mm region. Hoping to get ~450bhp out of it and a wide power band with lot of torgue.

Thanks!
