My Ride: 323i 2000
323i auto supercharged?

Hi all,


I worked on the body of my baby 323i (some say its weak) and well, now its time to work under the hood, and well, i want to make it as fast as an m3 (willing to spend up to 7k) i would buy me an m3 but cant afford it, however, first thing that came in mid was supercharging it, and was wondering if an auto tranny can hold up on it, i know how to drive stick, and i really dont like it, however. a friend suggested trading it for a 330i coupe, convert my 323i back to stock, and hold the parts for the coupe, so i dont have to buy them again.

Nonetheless, the question is, will a 323i hold if i supercharge it? like i said i like sedans, dont really like 2 doors, and im hoping to keep the my 323i and make it nice and really fast!

My Ride: M3 & 323Ci (sold)
There are SC kits for the M52TU engine which is the 323i. The automatic will have to take low boost and thus not make as much power. The subframe is extremely weak on the 2000 323i so it needs to also be re-inforced.

It is most often the better route to sell and get an M3 before the parts and labor on another car(you get a lot more than just power). Some situations it's fine to SC and keep original car. Since you want automatic and sedan I still would suggest if you haven't dropped alot of money already in the sedan to maybe get a 330i. But know that a SC is not street legal in CA and will not pass smog. It's going to put stress on other parts of the car. And with 180,000 miles now it's going to stress that engine more.

The good: if you just want more power it will give it to you. You can always sell the SC later. (but labor to install/remove and software costs all will be lost)

1. I'm 99% sure it's illegal to supercharge your car in CA

2. Supercharging an engine with 180,000 miles is not a good idea

3. If I see some jerkoff blinding me with 8000K lights and it turns out to be a 323i with an M3 front lip and 19" wheels, I will gladly introduce your headlights to the tire iron BMW conveniently includes in the trunk.

Too Funny

I agree with Most of what has been said already... The Mileage part is incorrect or subjective. if your motor has been maintained properly it will hold the added boost/stress of a sc But....

I think you should upgrade to a 330i if you want to stay in the E46 body style and consider SC That if the power isn't enough for you.

SC'n your current 323i can be done but you will need to spend money modifying /re-inforcing other areas of the car that a 330i already has the capability to handle the power.

hhmm...

Hi All,

Haha, hhmmm HID 800K arent that bad, unless you dont have projector lights, which would just look ugly and silly,


As to your answers, thanks, if i upgrade to a 330i automatic, will it be fast and the SC would be good on it? or do i must get a stick car to be able to get the most of the SC.


Also, do they have 330i inside black? i really hate that light brown and gray interior, my car is black inside and its amazing, black vinyl doesn't crack, well haven't happen to mine yet, they seem like nobody sits on them! that new!


Let me know!

thanks!

Manual tranny can hold more power. Unless you build an auto tranny to hold it. And yes they have black interior for a 330I. Just keep searching

If you want to supercharge, one of these should do nicely:


ESS Twin Screw kit for 323i

Doesn't look like much, but of course that's the plan, keep it subtle, keep it a sleeper so that they don't know what's coming! Power is rated just under 300 so you'll have a lot under your right foot as well! PM/Email or call me up with more questions - 714.582.3330 extension 8002, and ask for Jurrian!

Hey There ,

Welcome to the F/I section of the forums. Glad to see that your ready to enter the Force Induction world with your E46 323. I would recommend performing a Compression and Leakdown test on the Motor to see the current condition if the Compression and Leakdown is less than ~5% of each other then you are clear to go. As for the Automatic Transmission holding up the power it varies if you beat the car and go full throttle every chance you get well lets just say your manual driving skills will come in handy unless you want to build the Auto Tranny like Trippin Bimmer .

If you have any questions please feel free to PM me directly or contact me directly at Viral@activeautowerke.com and I will be more than glad to assist you.

Looking forward to hear from you soon.
