Hey guys, I recently purchased a '04 WRX. The guy who owned it before me drove it very hard and didn't install a turbo timer so the turbo has coked up. It needs to be replaced and I'm thinking of just upgrading the turbo instead buying an oem one. I know I would need to upgrade the injectors and oil pump and get a new ecu map. Also I'm putting a turbo timer on it. Are there any other upgrades I would need to make to the engine? Also, It came with a CAI a TBE and an upgraded BOV.
