Thanks for the advice, I've got an ST170 fund set up, just waiting for insurance to go down! May just get a cheap set of springs and flow the head just for the fun of it. I suppose with my kind of budget i'd get naff all power increase out of the 1.3. It reminds me of my old Fiesta's Valencia engine! Anoyone heard of any interesting engine conversions done out there? I am itching for something to do..
