Most obscure e90 option?

The other thing I've realized is that there was a change to the electrical architecture of e90's in 2007.The fuses and DME relay that were integral to the harness prior to 2007 moved from the engine box to the cabin, no longer integrated with harness.

It's still not difficult to add the relay and fuses, but the e90 harness seems too short on the injector/coil side anyway.

Will probably get X3.

Exciting news. We need more of the swaps!

We were reviewing basic Dynamics 101 material, and although a 125 ft-lb rating doesn't sound like much, it's at a higher rotational speed at the driveshaft, and translates to 406 ft-lbs at the wheels through a 3.25 differential.

oh yeah, I had forgotten about the difference in the transmission between the 325/328 and 330. Regardless, a 6mt sells for like $800 alone, so you did pretty good on that engine. Also, BPC broke theirs at like 500hp (turbo 325i), so I really doubt you will have a problem.
