Ok I got my hands on a JCW tuned 2002 parts car. I have an 06 S that has high mileage that I was thinking of replacing parts on as they fail. I already put on the JCW exhaust which I love. I know both SC are the same other then the pulley's. Did the early JCW kits have an updated cylinder head? And if so would it be worth changing cylinder heads when I replace the SC. Anyway what are your thoughts on any more parts that I can use.

 

The only difference between the 200 bhp and 210 bhp JCW Kits is the latter had an airbox and larger fuel injectors with an ECU remap for them.
