If you have Mini cooper JCW . What you will do to modify it ?

Which brand you will use ?

 

A new cylinder head and a stiffer rear sway bar.

 

... with a port matched header and tuned exhaust to go with that new head ... then an ECU tune.

 

My JCW kit was installed by the dealer in Jan 2003. It didn't come with a CAI so I put a K&N typhoon on.

M7 STB. This design was better than the JCW imo as the M7 design will help to prevent the mushrooming of the strut towers issue.

Alta Intercooler. I've got the bigger one that is similar to stock and a Alta DFCI that I got used and will try that one out too.

Just purchased a Dinan exhaust. Not really a big fan of the JCW exhaust. Doesn't make enough sound imo.

I had stock 16in wheels and went to OZ supraleggra's in a 17.

Will probably do a header at some point, JCW Suspension, JCW Brakes

I also put a H-Sport rear sway bar on.

 

But i don't want to change the head. Is there different between JCW pulley and JCW GP pulley ?
