Since my car warranty, is flipping out that the repair is 30k but they have to cover it, full exclusionary policy and paid like 7k for it, prior to this repair, they paid 8k for all kinds of work, month later, found the chain guides blew up and all in the oil pick up line.
Im considering getting the M5 Turbos (bored by Turbo Labs) and exhaust manifolds if i am going to get a forged motor, its less than new one from BMW, budget for motor is 20k, so i have some room for other parts..
Only real concern is front axles and transfer case, the two weak points, you can put M5 axles on the rear, but no one makes anything for the fronts, might have to get something custom made..
