Forced induction

2005 E46 330i Sport Step - what's the best method / product for forced induction? Supercharger or Turbo? Don't want to break the bank either.

2nd question - where can i get it installed? No way I'm going it myself. I live near Nasvhille TN - what's average install cost?

Thanks.

from what I understand...FI isn't the best idea if you want your step transmission to last...and if you were to go FI, there are more kits to supercharge than turbo (I actually haven't heard of a turbo made for the e46). As for the cost for labor, not a clue.

it is possible to force induct an auto, but I wouldn't advise it. As for breaking the bank, you are probably looking near the 8k mark with labor...

Numerous people have SC's their automatics with success.

You're not gonna get very far then. F/I and "breaking the bank" go hand in hand

Yeah I dont think the auto trans could handle that much power for very long.

wow has everyone forgotten how to use



and i've been s/c for almost 2 years now no issue's at all with my auto. just take care do the proper maint. on both your tranny and engine, preventative when needed as well.

as for auto trannies in general and their reliability some are rock solid others are . its a hit or miss scenario rather, then live in "fear" of when it's gonna go. do what you want, be careful and use common logic. if/when it goes either swap to a manual or get another one. your already considering dropping 8k for FI may as well budget out another 2k for a new tranny or about 4k for a manual swap.

It has a lot of do with your diving habits. If you drive like a mad man then yes your tranny won't last very long. I believe automatics can handle up to 250 ft lbs of torque to the wheels. Go with a supercharger with no more then 6 to 8 lbs of boost.

But not long ago I found a theard on a member that actually asked about the same thing and he found a manufacture that makes proformance kits for the automatics on e46.

My Ride: 2001 BMW 330ci
I have a 330ci with a step. I have been debating on FI for this car. I have made a decision to buy a manual 2001 - 2002 330ci in late January. Then purchase Nicks turbo kit for $6900. The manual swap is just way to expensive. If one decides on the manual swap he would be looking at spending 25% of the total value of the car.

Treehouse Racing (they are in Nashville) could probably do the install of the turbo kit.

If chose to S/C the step. I would buy the AA kit for $4400.00. You can get a upgrade kit from IPT transmission for the step tranny.

Im in Gallatin if you have anymore Qs or if I can help in anyway just PM me!!

My Ride: 03 ZHP AA Stg II
I live in Nashville and have an AA C38 Stage II Kit on my manual. I wouldn't go stage two with the auto though. They say stage I is fine on the auto though. I used Carma Performance to do the install. They are great guys and have a dynodynamic dyno as well. I'd recommend them to anybody in a heart beat.

Do you remember the cost? How long does it take to install?
