for more horsepower. get a m3 or a bigger engine. supercharging and turbo a small engine is quite not worth the time and money.

Only if ASC is kicking in and cutting power off the line or during hard shifts.

20hp out of a 323? That's probably going to be expensive. All the relatively affordable bolt-ons probably won't be enough: Headers, full exhaust, intake, underdrive pulleys... The easiest way to get that power and much more would be to go forced induction with a turbo or supercharger kit, both of which will run a few thousand dollars. Honestly you're probably better off selling your car and buying a 330i and getting an extra 30hp that way, or an M3 with the extra 140hp.

It's gonna be more expensive than selling your slow ass car and buying a 328.

Horsepower increase numbers are estimates and are pretty generous. They likely won't actually get you that much... 30 horsepower is really a weird and kind of hard to reach middle ground of power increase in our cars. You can get an extra 20 or so if you throw lots of money at it, and over 100 more if you go FI. Power levels in between there require really expensive things like cams...

Cat-back exhaust ($1,438 / ~<10hp) http://www.ecstuning.com/BMW-E46-323...nce/ES2563942/

Pulleys ($250 / ~<5hp) http://www.ecstuning.com/BMW-E46-323...eys/ES1910144/

Intake ($250 / ~<10hp) http://www.ecstuning.com/BMW-E46-323...ntake/ES11537/

Something to keep in mind is even if the horsepower estimates I put there were totally accurate, (they're not) they don't necessarily add up. 10hp from an intake an 10hp from an exhaust doesn't mean you'll get 20hp combined from both. Also, often times the listed power increase is only valid with a higher end model and will do absolutely nothing on yours, or will only give you the increase if you already have other mods. The exhaust for example could get you 15hp on a supercharged car, and 0hp on a stock one.

Honestly any BMW - especially a lower powered one like a 323 - is the wrong car if you're looking for straight line speed. I highly recommend steering away from drag racing, get into autocrossing / track days, and build on a BMW strength: Handling. Suspension mods and even better drivers training will get you way more bang for the buck.

You could put in a cold air intake that would probably give u 5-15 go increase and if u put a cat back exhaust u could get 40+ hp (pretty sure it more but) together plus high octane gas maybe u could get like 50+ hp

Whether or not the acceleration is faster with ASC off really depends on a few factors. If your tires lose grip then ASC will begin limiting the power to the wheels in order to regain traction. Turning it off will allow the wheels to slip and WILL NOT reduce the power. So, assuming your tires spin from a stand-still its probably better to turn ASC off.
My 535i has immense grip but it occasionally slips a little bit when the turbo's spool in 1st gear - I usually turn off ASC in these situations because it still has enough grip to accelerate without unbearable wheel spin. I don't want to lose power for such a little amount of wheel spin.

As for the power there have been some good comments as well as some bad ones. As already mentioned you can probably gain ~15-20hp for around $1500. Any more power than that will be expensive, without Forced Induction.
As a general rule: 100 pounds = 10hp. Obviously subtracting 100 pounds doesn't add 10hp, but rather they are equivalents. In other words, you will see similar results in the 1/4 mile if you were to add 10hp or subtract 100 pounds.
To add power:
1) Cold Air Intake (5-7 hp)
2) Full Exhaust System (6-8 hp)
3) Tighter Pulleys (3-5 hp)
You're looking at gains of 15-20hp MAX with these modifications. However, max hp and torque isn't the only thing that matters. These mods will also help to improve your numbers on the lower end (possibly more than 15-20 torque in certain rev ranges). After you install these mods have the car dyno'd and tuned for these modifications. You could get some sort of chip - however, I recommend you have it professionally tuned by a shop to maximize the efficiency of these mods. You could POSSIBLY see another 5-10hp gain from an ECU tune (this could be quite costly - like $750+).

Additionally, see where you can shed some weight. Rotational and unsprung mass is the BEST kind of weight to shed.
1 Pound of Rotational Mass (RM) = ~4 Pounds of Actual Vehicle Mass (AVM). Wheels, driveshafts, and any other moving parts are where you will find the most beneficial weight loss. I swapped my crappy Run-Flats for Michelin PSS and dropped ~6 pounds in each corner. 6 x 4 = 28 pounds of rotational mass.
28 pounds RM x 4 pounds AVM = 112 pounds of Actual Vehicle Mass. This would be the equivalent of adding ~10hp.

1. Not in a 323
2. eBay performance chip with eBay exhaust and eBay wheels = +35HP guaranteed

My Ride: '99 Techno Violet M3
When I scratch 2nd in my M3, ASC triggers and it significantly reduces my acceleration until it stops intervening.

I hate when systems do what they're supposed to.
