My old puma engine made 150bhp on sitechs rollers with a full decat exhaust, cold air intake & frp cams but don’t know how accurate they’re rollers are. After that I got the frp map loaded onto the tape ecu that had also been adjusted for 99ron fuel and fitted a 2.0 zetec throttle body but sold it so didn’t get a power figure afterwards.

with the 4.25 final drive it was a fast little car not far behind my mates 300hp sti ra surprisingly and also remember coming home from ford fair with 3 of us in the car and luggage and had a pop with a series mcrae Impreza and pulled away from it lol.

from what I remember they cost a bomb to make more than 150hp as not many off the shelf parts and the crank isnt keyed ect, personally fit a better engine like a k20.
