3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I was on http://bavauto.com/shop.asp and they have a supercharger kit for like 6 g's should I get it instead of a 330 Ci? Also has anyone ever done this to their car, lemmie know how it went. I like the idea of having a sleeper 325 and it would be cool if it's not very common. I just don't want to waste my time. Also has anybody heard how much the dinan kits costs? I'd rather go that route.

WOW! 325 bhp (crank) is a very big improvement; definatly would make the 325 a sleeper. A car w/this set up would be doing circles around a 330.
But you would void the warranty and shorten the life span of your ride. If you already have a 325 i would say go for it but proceed cautiously. N/A engines are not designed for 8 psi it will prob need new internal components. Not worth it in my book.
If you are really looking for a sleeper w/300+hp consider a c32 amg or a Volvo s60 r, debage them, get aftermarket wheels and they will look just like their sedate weaker versions
Yeah the internals were a concern, however my main concern was finding a supercharger that wouldn't void the warranty. I believe Dinan has one I just can't seem to find the info on it. Also from what I understand the 325bhp is without any other mods exhaust included. I can only imagine what a complete overhaul with that system would produce.
The other thing to take into account is what tranny software would be acceptable along with the added stress on a stock tranny for a 325. Anyone know what if any improvements are on 330 or //M trannies.
I have an AA Supercharged 325Ci with other mods. The internal engine componenet will be fine, as long as you know what your doing. Of course if you drag it every weekend, your bound to have problems. But it is a very nice mod, at the wheels without any other mods you will be pushing around 260-280, but dont let HP numbers scare you, its fast! Its your torque that really moves you. Im not sure about the bavauto SC but with mine, I have to change the oil every 20,000 miles, the oil cost about $100 but it deosnt take more then 1 quart. The serpentine belt also takes a beating and needs to be replaced more often, I noticed mine cracking so Im getting ready to do that.
My warranty was voided for my drivetrain, so you will have to take that into consideration, if you have any problems it can be expensive.
So basicaly if you do SC, you will have to take extra care of that engine, change the oil more often, flush radiator more often, and just treat the car right and you wont have problems. That SC will be putting out some RPMs, you will need to get your computer programmed also, other wise youll be redlining and the governer will kick in before you have a chance to shift, that is if your drivinbg a stick anyway. Let us know what you do, and let me know if you have any other questions.
