Nothing at the moment, coz im happy with it, plenty of power for me as i used to drive a fwd celica haha.
But plans r in the near future, Bosch fuel pump, a boost controller, rb25 turbo and ecu. Not sure on wat boost controller and ecu to get. Powerfc's arent available anymore, is that correct? Is there something round the $1000 mark. I might just get a safc coz im only chasing 200kw
