If you want more than 300 then just piss off the afm's. I am spewing that I didnt go a MAP based ecu from the start.
ID 1000's like Nick said, are the bomb
You have a lot of choices for fuel pump, Bosch 044, Nismo, Walbro, deutschwerks etc
I recommend Link ecu, as your looking at close to the same amount of money as buying a powerfc and z32 ecu's.
Also look at the just jap autech style catch can. Few guys have run them, love them. Mine is going in tomorrow.
