10.5:1 is too high...you need about 8.2:1 and it will easily see 250hp

A little hint, ST170 head gasket is a 4-layer full stainless gasket and is nearly 0.5mm thicker than the standard 3-layer version used in other black tops.

calibra turbo pistoons do have a ratio of 9:1 ando produce a fair bit of power, these are a popular choice of piston by ZVH builders. but i have got steel rods and the pistons wont fit them, think i may be buying a set of custom made ones from diamond, and have already chose my managment (emerald).. will see how it goes.

The only real difference (if I recall correctly) between the 2 engines is a crank/rod geometry change with the better geometry being in the black top. Ideally you want the crank out of the black top too so you can take full advantage of the revised geometry.

davsmith64 the best advice i can give is give Ian a call...he will even probably have pistons in stock for you! prices are very cheap and he aint known as the Zetec God for no reason
