So no tuning? I thought OBD1 was easier to mess with than early OBDII but I guess not.
I've heard a TD04 and WRX inter-cooler on the stock ECU is a good upgrade? I've also heard the stock 02-05 WRX intercooler is the only topmount that fits?
Walbro 255 I'm guessing for fuel
Whats a good up and down pipe to use? Does the 22T use the same headers as the 255/7 and 207?.
I've also read a lot about putting EJ25D SOHC or DOHC heads on then but the bore isn't the same, how does that even work?
