The I4 is a better engine to start with - 150bhp and 145 lb/ft. Chip, cam, exhaust and panel filter should see around 170 bhp. Then you can go management and throttle bodies for around 200bhp, then you can go high comp etc for around 240 bhp NA.

Think they do an I4 conversion into mk3 fiesta for £1K
