OLD, but exactly what I’m thinking… I’m trying to save up for a first car, hopefully a S13 Coupe and I think I have a pretty good knowledge of what does what and how (better this year cause Gr.11 auto class is more “in-depth” :)). Right now I’m removing a 3.3L engine from a crappy '92 Grand Am and then maybe overhauling it, so I’m sure I’m going to learn a lot more from that… After reading this thread though, I know I better buy some books and stuff cause I know nothing about EMS tuning and I better learn before I get into tuning anything :study:
