    St170 build spec's and power figures.

    So I'm looking at building a St170 but would like to know what spec's people have built and power figures they have achieved. Engine is destined for my Mk1 escort. Mainly track and competition with light road use. I'm currently running a stock St170 with vvt delete, Jenveys and MBE management making 180bhp at the flywheel. It's very good but it seems like it wants to give more. What head work have people had done? Anyone use bigger valve's? Have seen 1mm bigger are available. I have seen that IK engineering make a 2.2 forged stroker kit. Anybody used one and what power figures were achieved. What Zetec dry sump system's are about. Any recommended manufacturer's? Thanks for any replies in advance.
