Sorry N54 NEVER had forged internals.

The crankshaft is forged, it says it on the n54 mechanical engine section PDF, while the N55 engine PDF says is cast iron... but it doesn't say that piston are forged on the N54 like a lot of people think.

Correct, the n54 had a forged crank only, which I wouldnt consider as being "forged internals". However the N54 never had forged pistons or rods, ever, which is the myth that is flying around the forums that the N54 had.

I've decided to NOT go with the simpler upgrade I was anticipating for month end. That said I am going to (attempt) to do a more thorough job and come up with something VERY remarkable for the N55 crowd. It will cost more to build but I don't think anyone will be complaining if all goes to plan. Will know more when parts are in my hands shortly. I'm actually more excited about this than ever

Another update from rob looks like we are getting closer and closer

In the meantime, can someone post some pics of how the turbo sits in the car? I am most interested in seeing how the compressor housing is plumbed (inlet and outlet). This will help me get a quick scope of some extras I may need to produce.

BTW, if I can pull this off, I fully expect about 100hp (crank) gains and a sub $3k price tag. It is a single turbo but the donor parts are very cutting edge and hence big $$$.

Thanks,
Rob

I realize that it is early to talk numbers but the above quote mentioned 100 hp at the crank so...

I interpret this as about 85 at the wheels. Figuring an FBO n55 running e85 should conservatively run about 360 hp. I'm guessing we would see a conservative 445 with some seeing as 460 to 470. That would make for a pretty fun car.

Does everybody see too?

Just did some e85 tuning on a buddies '12 335xi FBO with PROcede & PWM Meth. Had a glitch where the PROcede would just reboot, but we fixed it by putting a cap on the power line. Posted the fix on another thread if anyone is interested. Cranked up the timing and target boost to 20psi. Never felt an N55 pull this hard. Only issue now, to much torque for the clutch to handle... Sending it over to HPF for a clutch upgrade in a few weeks. Then some final logs and off to COBB for a dyno run. Hope to see 400 awhp.
