So, I am very new to the Starion/Conquests and have "relative" knowledge of engines but mostly naturally aspirated enginges. Since I didn't see this anywhere else, I thought maybe I'd start a thread (I apologize if I missed the thread and in that case just delete this one) to get some quick and dirty tips on tuning these cars. I'll start with a basic question: 1) Can you swap turbo's (upgrade) to a bigger size without changing stock piping? My car is totally stock but in pretty good shape. If so, how big and how much boost with this stock engine take? 2) Besides a new air intake, what is another quick way to increase performance / effiency? Any and all tips are appreciated. I am looking to bebuild the engine at some point but it probably won't be till next spring/summer so for now, I'm looking for easier, non-invasive changes.
