Ok so I'm currently building my '04 GS3, at this moment the bottom end is at a machine shop to have new connecting rods and possibly even pistons and all internals replaced. I already have I lost of items I'm going to be buying to turbo this baby and get it to about 600HP. my true question behind all the information is, what type of engine management should I use? that's the only thing I'm currently stuck on. what type of ECU and why. I have the turbo kit, transmission for the manual swap (CD009) I have the intake and such just no clue on the electronics (ecu) part. help me put peeps!
