Buy a plus 4 , put some throttle bodies on it and or put some faster cams in , get the manifold off and get a Librands manifold ! My plus 4 was 180 bhp when I bought it about a month ago , now its circa 220 bhp ! Its brilliant ! Ring Northants motorsport and ask what can be done to a duratec 2litre engine - masses !!
What was your spec at 180bhp and now at 220bhp?
