The n54 is one tough motor for sure

These motors are extremely strong the thing holding most people back is a solid fuel system.
Looks like they got it solved, they added an injector rail to the intake manifold and injectors controlled by AEM EMS. They arnt using Meth yet or race gas. In their thread on bimmerboost they said at 34psi they maxed out the ignition system. Protuning freaks said that the s55 coils are better and are n54 compatible. So will have to wait till they go full kill mode.

I would imagine if they get enough interest a better HPFP is a better solution. The fuel system was the one thing holding @DrDoS back from making more jams.
Vargas has a solution for that as well they call it the “shotgun” and they even off duel of that called “double barrel shotgun” lol duel hpfp but the price ain’t cheap, the parts are out there but the money obviously ain’t lol

It looks about the same price as compared to a regular car where you would upgrade injectors. 4 ID2000 are around $800. And then a twin hanger pump setup is another 500
Big power cars just run the dual rails so the driveability is better and easier tuning. 2000cc injector will make over 1000hp on a 4cyl running e85.
Just run it to the aem, when there’s a certain load it completes the circuit and bam shit ton of fuel lol
