New fueling system

Exhaust manifolds for the n54
And it is a very strong motor if you havnt seen the 750 hp 335 now being built, this motor is great!!!

More than likely, this is what BMW will do. The N54 was "killed off" because it lacked the reliability & emissions that the N55 was able to deliver. But somehow it keeps resurfacing -- 1st in the 335is, then in the 1M, and now in the 135is.
The high horsepower 335s are the single turbo applications (I haven't seen any RB/upgraded twin turbos going over mid-500 unless they're running meth), so I think BMW will stick with 2 (or 3) to prevent turbo-lag & try get the motor as close to the naturally-aspirated feeling as possible.
