As a general rule of thumb, the E46 has a better suspension than the E36 (330 vs 325/328). The 328 has more torque (but basically same bhp) than the 325 but it's OBD2 and has a more restrictive intake manifold.
As for coupe vs sedan, I've always been told that it makes no difference in rigidity. It might be easier to get in/out of a coupe in the event of an accident though. Somebody correct me if I'm wrong, but I thought I once heard that the sedan has a steeper windshield angle... May or may not affect aerodynamics.
If you decide on E36, it would definitely be worth it to find a non-moonroof specimen if you can, because that would save you the trouble of having to weld the moonroof sheet metal after you remove the moonroof mechanism. I don't know if any E46's shipped without moonroofs.
Then there's the weight thing. I believe the 325 is the lightest of the bunch.
I'm still as green as a noob can get, but from what I've read, it's speculated that the 325 won't be a front runner.
I'm sure Marshall and other seasoned veterans can provide more input. [/b]
The advantage of the bigger wheels & tires will help the 330 more.

I disagree here. 500lbs lighter on the same wheels and tires IMHO is a HUGE benefit to the 325. You know Bimmer's Dan, why would the 330 beneift more? Maybe the 325 can't fit the big guns...

This will be interesting. The 325 is essentially the SM of ITR. Light. [/b]
Interesting feedback, all - thanks! Backtracking a little, is there anything to choose among the e36 325s? K [/b]
I wonder if some built but less expensive ITS E36 cars show up plentifully in ITR. It could be the economy way to run the class (not that there ever really is). I also wonder what class ITR might pull from the BMWCCA drivers. JP? I don't know their classes well.

I think your point assumes that the 325 is maxed out power-wise with the new-found tire width. That is where I don't follow. You ever follow an light ITA car with the same size tires as you through some twisties?
I guess the only question is whether or not the E36 can FIT huge tires...just another reason why I think the E46 325 will be a GREAT choice.
Any way you slice it, BMW guys have a ton of REAL choices for ITR with the BS of engine restrictions. [/b]
Thanks for that! You have 2 minutes of track time credit banked for the VIR 13. More good input and you can have a full lap!Yea K, one with a pro cage & suspension. That advise will cost you some seat time when you want to win an enduro.

As for the power of the 325's, lets start with the E46 325's. It will depend on what type of software that can be programed into the ECU since they don't have chips. That is why the ITAC should make the recommendation to drop the ECU rule as it is and allow EMS. With this we may be able to keep up with the current cars and their newer OBDII ECU's, so we won't be maxed out on the engine.
