what are your goals? what are you trying to build your WRX to do?
the raceland coilovers are crap. get some bc racing coilovers.
do you realize what it actually takes to run a rotated turbo? you need to go read threads on builds in the proven power section
FYI... im pulling my perrin fmic off my STi in Aug if you're interested in buying it then. there's nothing wrong with it. i was just able to pick up an APS fmic instead, so im swapping them out.
