sorry to hijack the thread but i'm building a zetec turbo and thought that a comp ratio of 9.0:1 might be a little too high and leave no margin for error if the fueling were to run lean.

i'm looking at rod/piston packages from the states listed on ebay and the lowest c/r they seem to offer is 9.0:1, tbh i'm very tempted by the price.

i'll be running a 2 litre (silvertop) zetec with a t34.48 on megasquirt or microsquirt and am looking for 300 bhp.

i'm really just looking for more re assurance that the comp ratio will be ok with my spec.

thanks for any help
