Hi, I just got a 1994 Aura integra rs and I love it. It's pretty quick compared for what I just traded for it, which was a 1998 Chevy Tahoe gas drinker. It looks great, and better yet, it doesn't even have 60k miles on it yet. I have never modded cars before or even thought about it untill I picked this one up. Firearms was/is my passion, but now I think I want to do some stuff to this car.My questions are:

What is a Vtec engine? I know my car isn't a Vtec, but I wanted to know about it. Why is it so great? Am I S.O.L without it, or can I mod it where it wouldn't have mattered anyway?

If I ever wanted to, could I put an F-max turbo stage 2 on it's engine stock without hurting anything? Pros/cons

The Mods that I'm thinking of doing right now are, Lightend flywheel, cold air intake, headers/exhaust, then a chip. What kinda gains can I expect? I have driven a couple of fast cars here and there, like a z28 camaro, Eclipse Gs-T, Honda s2000, can anyone maybe give me an example of the kinda feeling of the car after I do these mods I know it may sound stupid, but I'm trying to get an idea of what I can expect out of this car with a little work done to it. What kind of damage to stock internals would I be looking at by doing this stuff? Well that's about it, any other info or suggestions would be great. Thanks, Ramsey.l
