The problem is bolt ons on a N/A car usually provide MINIMAL increase in power. We're talking about 2-5WHP per mod. The reason is nowadays car manufacturers that produce N/A vehicles want to get the most out of the engine as possible for the consumer so this means you get "factory tuned" parts that work best to create power. Making MORE power by adding aftermarket and "better flowing" parts change the power output minimally. Now Turbocharged Vehicles from factory are normally "Undertuned" to keep it making good and reliable power (avoiding detonation, providing good fuel economy, etc.) so when you put those same "better flowing" parts, they make POWER.

From a Boost Head (you can see in my sig the OTHER car), FI isnt a cheap hobby. This is especially the case when its your Daily Driver which that was the case in my younger days. Both a Nitrous or FI car can be done in a safe way with the right parts and the right tune. If you do your homework and not cut corners, you can do it. As far as having 15k available for use, Ive never bought a turn key turbo kit but rather I pieced them together in a slow process. It does still add up but then again "You gotta PAY to PLAY". I will not even start calculating the amount ive put into my toy but I can say its fun spinning tires in 3rd gear @ 20+psi.....

thanks for the input guys...i was really craving some extra power but from what everyone has said i think it is reasonable to not spend the money on performance mods. I like the way the G sounds already, and it seems like that's pretty much what the bolt-ons do to the car, make it sound better with minimal gains. Instead of buying 2000 dollars worth of performance parts, I think I'd rather buy a used yamaha r6, volk gt-f wheels (doubt it. too expensive), or kenstyle front lip with stillen wing.

 

That's an excellent idea.. u'll smoke that 335 with no problem..... I ride one myself.... I'm a track junkie.. so if I ever need to get a speed fix, i do it on the bike... top speed so far was 168mph indicated..

 

This is from experience (I spent about $10k in performance mods on a car that responds well to them an 02 Trans Am).

I was disappointed with EVERY mod I did. Nothing gained as much as I had hoped. I researched the heck out of the mods, did only the ones with the best gains, and was disappointed. For the same $$, I should've just gone forced induction.

Here's 4 reasons:
1. Guaranteed gains
2. You'll be faster in the end for less $$
3. If you're unhappy with the speed.... MORE BOOST.
4. Resale. You'll get way more money back with FI.
