Right now I have a 97 NA 5 spd with 56k miles. So far I've only got a custom intake with akimoto filter and a Borla exhaust with the 2nd cat removed. My next thought was to get some 8mm+ wires and an HKS twin power ignition, I'm running stock Toyota Plats, so I dunno if I'm gonna have to replace those or not. What should be my next step? I want to do everything I can before really having the engine torn apart.
