Currently running a 2.1 zetec turbo in my Racing Puma. Pretty much an RS build using standard turbo and injectors. Head gasket went this summer due to thermostat failure.
Thinking of uprating the turbo and injectors while it is bits. I've heard of 630cc injectors used as upgrades from standard 440cc.
What turbos are people using? Looking around the 300hp figure.
MK1 Focus RS Uprated Turbo and injectors?
