I know mine never got to 160, but I was well chuffed with my 153

Karl helped spec it and I built it:

std crank - blanced
Farndon Steel rods
Cosworth Forged pistons
std head gasket, oil and water pump
Karl Norris Stg 3 head with matching manifolds
Stg 3 T3 turbo on a 0.48 exh housing
Mongoose exh
GRS i/c
Std KE with the fuel mod
NMS chip

Engine was probably good for a genuine 230bhp. It was a cracking little engine
