Does anyone know how much boost the engine internals, like piston rings and stuff can handle? i know my eclipse could have taken like 12psi or something but i would imagine this engine is much stronger than a crapy old 420a.
Typical average boost pressure most NA engines can take with no internal mods is 6 to 8 psi. I don't think the 420A can take 12 psi, I know a lotta guys in the DSM business and the general consensus is that the 420A is made out of glass...... Like I said, 6-8 psi is right about where you want to be and not compromise reliability. Pretty sure you'll still need an upgraded ECU and a few other things.
