Supercharging is over priced, turbo-kits dont exist. Although it wouldnt be too difficult to make one if certain companies on this forum would be willing to sell manifolds seperately from their kits. But dont bother asking them.... Xi's are good daily drivers but do not take well to many modifications. Your best bet would be to just leave the car alone and take good care of it.

Suspension is the only thing I would upgrade on an xi.

Both were warned about running in cold weather and Vortech even has listed in their limited warranty as one of the requirements as to not void the warranty, Subjecting any Vortech supercharger to a "cold start-up" condition (below 25° F) without the

Centrifugal blowers need to be heated up so the blower gets properly lubed up otherwise it will/can freeze. There are other blowers that have their own oil supply in which cold weather probably won't be such an issue.(roots style)

I wouldn't personally even bother with going FI in an iX.

Now you say a supercharger???? imagine what the transmission wil look like after 5000 miles with the constant reving of rpms for a car that comes stock to handle 185 HP! He went on and i listened...he was 100% right. Want to have HP? purchase a car that is desined to handle and deliver it...a M3! or purchase the proper equiptment to do it!!! lotsa $$$$$.
If you want to play...... you GOTTA PAY!
This is an informative rant. Interesting comment about the CV joints.

He is from Bavaria...has owned a repair shop here for 20+ yrs, -is german and is a plethura of information! He also was a Formula One mechanic for quite sometime, started racing in Germany when he was 18, worked in a high performance auto shop in Miami during the 1980-(near thunder alley) This guy knows BMW, Audi, VW and Mercedes,Porsche like no other!!!!!. I asked him about a Super Chrger for my Xi and he looked at me with the most sarcastic respnses I ever heard! LOL.." zee xi is for AWD! not vor 2wd..racing!!!!"
lol cool story bro. wow i actually took the time to read the whole story.

Hi Ed,

I can't believe you spelled it iX, but I will have to forgive you, since you hook me up all the time when it comes to parts...

(FYI Fanatics; Ed is a customer oriented parts guy, the kind that makes me call the dealership first, when I need parts! If you are not too far from Grand Blanc Motorcars in MI, def. give him a call if you need OEM parts...)

Anyway, I'm still tempted to get the OEM cam kit. Looks like the general consensus is that the supercharger has too many potential issues, for a winter driven AWD car.

(Or maybe I need to figure out how to not spend all my money on sailing, so I can get a Lotus for the summerfun... )

like i said, it will be fine for the most part as long as you dont launch your car at every streetlight. drop it down a couple gears on the hwy at 75mph and feel the SC power. if you want more power but want to keep your current car for another 4-5 years like some of us, i think SC is the way to go. otherwise, youre just gonna have to get a 2nd car that is much faster or just be quiet and accept your slow car for what it is.

btw, even if you launch your stock NA xi because "AWD is supposed to pwn RWD off the line if you launch at 4krpm" you will still destroy your drivetrain quicker than you can say "i really want to SC my xi because i'm sad that its really slow and i dont want to go through the trouble of making it stock again, selling it, finding a used M3, buying it, maintaining it, and then turbo'ing THAT which would cost a whole lot more than just SC'ing my 330 in the first place". Hell, even stock E46 M3's can have messed up rear axles if they launch it too many times on the track... i've seen a youtube video of it.

you only have to sacrifice one thing: launching. besides that, you'll be set. feather the clutch into 1st gear, then for the rest of the gear put the pedal to the metal and win that medal.
oh btw, after SCing a 330, you'll probably be slightly faster than stock E46 M3s and stock 335i's... but i still think its a good/fun route to take.

One of my buddies that has a 2002 330Xi has ESS Supercharger @ 9.5 PSI w/ MT Re-Flashed ECM, he is pushing about 350BHP on a good day...his transfer case has been holding up so far with 30K miles already with the S/C.

why even waste the money tho? its so expensive and possibly a headache from the issues you guys have brought up. i say enjoy the ride (maybe a lowered/sporty suspension to give a better feel) or get an M if you want something with more than 194 hp....its your car though so do what you want and enjoy it

Supercharged

If you supercharge it and own it long enough, be prepared for an early head gasket failure and a $1500-2000 repair. I have a E36 M3 and my research leads to the same conclusion for an E46. Also, depending on your driving habits, OEM clutches can be eaten up faster than normal.

I talked to ESS, They said Stage 1 will be no problem, they will not recommend Stage 2. And OEM clutch will be fine. Getting it this spring.

An aftermarket clutch would engage more solid and you will feel a huge difference at launch with the power. I installed a 6 puck copper ceramic clutch in my stock 04 325xi and it feels awesome. It still has springs so it doesn't shudder too bad. If you are going forced induction, having the solid engagement without slip will make a huge difference and you will love it.

Renew your head gasket, change injectors fuel filter, pump, mount better air filter with a nice sporty exhaust.

+ Kw coilovers, powerflex bushings and nice large 18 wheels forget 19 " !!

Then go to digitaltuning.ch and optimize your eprom. That's it !

You will gain around real 50-60 HP without risk i know not too much but you will notice the difference.

My Ride: 2002 BMW 325 xi
Sigh some of the information is just heresay. There are folks who have been running SC's on their Xi's for some time. If you want a turbo, http://forum.e46fanatics.com/showthread.php?t=773653 is one thread where a guy is building and running his turbo setup. If you read it, you will see the things that stop an Xi and what he has had to do so far. SC's can be bought for your engine and as others have noted the setups are solid.

Keep in mind, when you modify the engine you decrease the reliability. That wouldn't matter even if you were putting bolt-ons on a chevy 350, you move closer to the designed limits and will experience failure. I seriously doubt the long list the other guy gave because it sounds like scare tactics and considering the folks that have SC's have had no problems. One thing I did read was that they had to do belt maintenance more often. No biggie but it illustrates the point.

Their website quotes a 17hp gain... In any case, how does one go about doing this and how much does it cost?
