The new e92 will have a minimum of 400hp, and it'll positively weigh less than the 335xi. You'll have a bit of an advantage because of the AWD, but you have to lug more weight around and have less power. All that Dinan stuff you listed won't give you much power, unless you get a bigger turbo. Even Dinan says so themselves, BMW's tuning is already getting so much from the setup that they won't be able to improve much.
It'll be a nice package to get around in, but I wouldn't go around trying to hunt down e92 M3s if I were you. I'll tell you my personal experience. I bought an e46 330ci, while my brother got an e46 M3. My car was a little over 40k new and his just a little over 50k new. I could spend 10 grand on my car and still couldn't get the same setup that he got stock. That 108hp difference is impossible to fill unless I: (a) get an engine transplant; or (b) get a huge ass turbo. Even the cheaper option (b) will cost at least 8 grand; and we haven't even touched the suspension setup.
Forced Induction really changes the game, here. E46 330 v E46 M3 just doesn't apply. There is no way the E92 M3 is going to make that much torque on a low displacement V8. The numbers flying around are something like 400-420hp and 300-320 ft-lb of torque. Dinan aside (since they have yet to release anything for the 335), Shiv was able to take the car with a hacked together catback from 278/287 to 331/347 after a couple weeks of tuning. That is a huge upgrade with lots more potential. I'd bet with a turboback and tune, the 335 puts down similar HP and a lot more torque (maybe even 50-75ft-lb more) than the E92 M3. I'll grant you the 335xi will likely be a bit heavier, but that torque is just hard to beat. (You've heard the saying a thousand times.. HP sells cars, torque wins races... (unless, of course, your in an F1 car revving to 19k.. ))
I drive around a turbo awd car that puts down 302/356 with a turboback and 100 octane tune (same brand dyno as above), so I can only imagine what the 335 will do with some more dyno time, some better gas (Shiv only uses 91), and a free flowing exhaust, intake, and throttle body.
All of this speculation and magazing racing is useless, I realize; however, I've always felt that should I be ready to buy a new car, there'd be nothing out there for me. It's nice to see that there may be some options out there in the near future.
