Sorry man, adding an SC to a normally aspirated car is not an option...realistically.

There are options however, do us a fave and add your model and trim level to your signature, it will help determine what mods are availabe for your car.

Bigger diameter exhaust piping, and intake mods should help your engine breathe up in the higher RPM range... at the expense of some low-end, but considering how much the 3800 makes, it'* no problem

My car doesn't have a very good high-RPM range either (it'* pretty poor, actually), and a K&N drop-in filter doesn't do much, it just sounds cool, like an SC. You might want to instead consider a cold-air intake that comes along with a high-performance air filter.

The downside of a pushrod engine, is that there is not much more love after 4800 RPM, mods are necessary to get more out of it. Off the line tho..not much that can beat the 3800 engine

Yes, it is a compromise all around. If you need top end power, you give up low end generally speaking. Turbos and blowers help this out, but it does start getting expensive.

You could add a small shot of nitrous, like a 75 dry to get the edge? that would do it

Intake, remove the MAF screen, CAI, hi-flow cat, performance muffler, and a chip. Big horsies there.

ALL of that would cost you around $500-600, and maybe more for installation. But it depends on what you get. Intakes can be cheap or expensive.

But get a 180 thermostat for $12, an intake can cost from $37 to $200, depending on what you want to spend. Hi-Flow CAT less than $100, muffler for around $120, chip probably $299.

I'd go with the stat, intake and exhaust first! Removing the MAF screen is also easy, AND FREE!

If you're looking for one mod for now, I'd do the intake first. (and the 180)
