Teach me about ITR 325's

[ekim952522000]

i'd run one, i think.

before i did it i would want to find out just how long one can expect to go before the subframe mounts need to be cut out and new pieces welded in. i'd want to know what that costs, and how hard the necessary parts (OEM factory installed!!!!) are to come by. if it's reasonable, i would then move on to finding the weight/power balance i thought was best for ITR. i know the thread title says "325" but i'd look very hard at what the 328 weight is, and find out what the restriction point is in both motors. the 325 should be easier because the development has been done for ITS, but the extra displacement of the 328 might provide a torque advantage that suits your local tracks better.

my final question would be....what line of work are you in that you're building a new ITR BMW right after an ITR Prelude, and are you hiring?!

Does the 328 have the same rear subframe issue? f it does the 325 makes more sense to me if it does not then maybe the 328 is the way to go. Used version of each can be found for close to the same price.

Yes, it does. Same chassis, same issues.

The 328i has more torque but worse top-end because of a lousy intake manifold.
