The word is the N55 is all Cast, correct. The short block may hit a power limit pretty quickly (in contrast to the N54). |

I'm sure the turbo, as a piece of equipment, is solid. What I meant by "reliability" was how the whole platform responds to this kind of modification. Interested to see if the engines hold up, how the transmissions fare, etc. Without a doubt if you offer levels up to 750bhp, we will soon be finding out what the weak links are. My car has already had the HPFP replaced once and is going in soon to have it done again. I'm not confident that the stock fueling can handle this.

Turbo upgrade is all I have left to do other than the FMIC. Thanks Rob for doing this for the N55. N55ers need a reason to be excited lol.

I do think the 550hp kit should be a walk in the park for it. The 650hp kit may just skate by. I'd be pretty blown away if the 750hp kit is able to not push the short block overboard at max capability. All just my own guesses, no data to back it up obviously. Rob |
