Okay Peeps. Here's the scene. I wanna upgrade my engine by adding the Star Stage 2 Kit. Now here's where you guys come into play. I wanna know what else I would need to do to my engine to ensure that I get the most out of my Kit and at the same time not risking the explosion of my crappy 420A engine. I mean I want EVERY single detail (even boring the intake manifold). What is useful? What needs replacing? What can do harm? What else needs improving? Yada, Yada, Yada...Any and Every Suggestion is appreciated.
