Auto tranny that is modeled after the Mercedes 4matics (this is a five-speed, though). And this is all stock.
Now that I'm done bragging, here's my question:
Has anyone actually worked on a 2002-2006 Altima 3.5SE? I'd like to know what kind of hp/torque increasers I can put on it. Obviously some 3" cat-back pipes, and a cold air intake and K&N filter. That'll put it at just about 300 horses, I think. There's not a lot of room under the trunk though - how feasible is a supercharger or turbocharger? Obviously I could put a tiny turbo in there, but really, I'm trying to keep the money/power ratio in mind here - I'm not exactly makin' the big bucks. What about computer chips, or chip-program modifiers? Any help would be great.

If intake/exhaust puts you at 300 horses I'll eat my car. I'd guess closer to 260, 265 max, and that's if you're really lucky. Chips are generally a waste of money, especially if they're not put in to work with other mods. Turbo/supercharger is often the cheapest as far as horsepower per dollar is concerned. Make sure you figure out how much boost your engine can take without building it up. Supercharger will be more fun, turbo may be faster. SC will give you instant throttle response. It'll have that nice jolt of accel. straight off the line. Turbo will lag and the power will come on slower. It won't feel as fast, even if it is.
