Basically I've got a N/A EP82 and its got the 100hp 4EFE. I've been told that the gen1 engine is basically a GT engine with different Pistons. Obviously I don't want big boost.. I'm thinking 0.5/0.4 bar on a CT9, would the Pistons be able to handle this? I was advised to put a thicker headgasket, how thick? 1.5mm? 1.9mm? What would I need to do what I want? 4EFTE loom and ECU?
