It took more than 3 years since e46 m3's launch for the supercharger kit to be developed. I owned one for 2 years and I couldnt get it supercharged because the kit was not available. Would it be fair to expect a similar "delay" of any forced induction mods on the new m3? That would be horrible and possibly prevent me from getting the new m3... 400hp and 350tq just doesnt cut it with 3400lbs car. Active, are you guys going to develop kits for the new m3? I am sure there will be a lot of demand...

the thing with the S54 motor was that BMW did most of the fine tuning to get most of the juice out of the engine, so manufactors of charger kits had to make sure what they were developing was going to be stable. with the v8 4.4 liter the e90m3 is going to be having im pretty sure kits will be coming out a lot faster

It's probably going to come down to how finely tuned the engine is going to be...

If every bit of power is extracted from it, getting mods on may be a bit harder (as it was with the S54), if it is a pent up engine.. expect big boost mods fast.

nOT FOR A LONG LONG LONG TIME WILL THERE TURBO M ENGINES..

Especailly on an M3.... never ever!!

not ven this talked about 4.4L..

It will only be a high revving (as in 9000 rpm) 317 kW (at very least) 4 litre V8

oopss.... ya talking about modding!! Just saw the title and went mad!

In the case of my current car, an Audi S4 V8, the problem will be where to put it.

To shoe horn a V8 into the chasis size of a 3 series, or in my case the 4 series, is tough as it is.

I know that in about 6 months there will finally be an SC for the V8 S4 making just over 500bhp. But, like you said about the e46, it took about 3 years.

I'd say, if you need more than the 400-425 expected bhp, just buy the new M5 or something with forced induction already, like a Porsche Turbo.

As long as it's 400bhp+ and keeps the same curb weight, it might just take this Audi enthusiast away from Ingolstadt.

Time, performance and cost will tell......

If you want to tune a bmw for high hp, the car to get will probably be the new 335, the twin turbo 3 series. That engine will already be set up for boost by bmw. It will take easily to mods. This will be the car the tuners get. But give me the na 425hp M3 any day. Or better yet, a 333hp M2 that weighs about 2800 lbs!

By the time some makes a reliable s/c or turbo kit for the E90 M3, the next next generation M3 will be released, who knows what will be in that. It's always like that.
