Ok! So my wife has purchase a 2007 Saturn Sky (2.4L) 5 speed. It is a fun little ride, but no *alls! So, I am looking to add some power adders. I figure with the 2.4L, I should be in a good position to make a little more power over the 2.0L, pending upgrades. The displacement advantage has potential. In my experience, the only really bang for the buck is a power adder (ie turbo or supercharger or NOX). All the other additions such as CAI, TB, and Exhaust add up and give 20-30 rwhp at best. BUT these have a better results in addition to the power adder and not without.
My toy is a 2004 Saleen SC Mustang, with some extra work - 412 rwhp.
I hope this site can help with my questions. So far, I have read several posts and many questions have been answered.
Talk to you soon!
