Interesting link Emir, but why is software not in any of those packages for the e34? Kinda missing a big item there.

Maybe they just forgot to list it ... I mean, a FI upgrade wouldn't really work as it's supposed to unless you upgrade the software -- I'd hope they know that. lol

this site has a supercharger system but its almost $6500. anything cheaper?

They have the ESS one on there for $6000. Thats your best bet. Forced Induction is far from cheap when it comes to BMW's.

it sounds good, but it doesnt say how much HP and Torque would i gain from the 286hp i have now. also, what will the forced induction do to my gas milage? i would think it would make it worse. am i right?

i did some research on it.

What will this do to the transmission? i would think it would tear it up having all the power running through it. and my rear diff.? might have to change the gears too?

Thats a lot of torque. Youll defitnely want a better diff and no doubt youll need to spend another grand to grand and a half on a good clutch/flywheel.

Seems a bit high horsepower, especially since you're putting out so much torque and putting out 7 psi. At taht price I think youll want a intercooler and/or oil cooler.
