hmm look like they are going to port fuel as a primary form of fueling or a secondary. We have thought of doing the exact same thing but the cost of the kit would be so high with the introduction of an entirely new intake manifold. Would love to see them stay DI and work that way. That is what we are fighting with right now. Eric

I wonder how hard it would be to drop an S54 into an e92 chassis. Could just throw on the existing HorsePowerFreaks turbo kit. 1000hp has a nice ring to it. then u might as well go buy a 2006 highest mileage 325 for 13-15k. and then take out the motor for a built one.

Of course there is a limit to...

Thats why im actually waiting before i purchase my 335i.. still havent decided if i should get a e46 m3 or a e92 335i... as soon as i purchase my car.. within a week i will be getting a kit installed.. since i...

Anyways, this is still a year away from being reality so there's time for a lot of people to save up some cash. Oh yeah, I forgot, I have a year to save $40,000 for stage 4 because like you, I have no bills..... Oh wait.
