going to be putting my new ofam ecu in car when i get lambda n AFR. i read somewhere the standard fiesta rst engine will do 21psi at stock??
if this is true i want to run this in my fiesta rst engine with steel rods and forged pistons at 21psi.
i want to try and achieve around 250 bhp and around 230 lb ft.
i had mine rr'd at 14psi 205.7bhp and 186.9 lb ft which is pretty good i suppose but i want that little bit extra.
what is needed to achieve this? i dont want to go 1.8 or 2.1 bottom end just 1.6 will do. and help will be great thanks
