Stage 2 N54 335i build - full mod list and results

about 2 months ago· 21 posts

Finally finished my N54 stage 2 build. Heres the full mod list: - Catless downpipes - FMIC upgrade (Wagner) - Intake (aFe) - MHD stage 2+ map - Index 12 injectors - New spark plugs (NGK) Result: 420hp / 560nm on E50 blend. Car is an absolute monster now. Stock turbo limits are around 430hp so im close to maxing out. Ask me anything about the build.

Sick build man! 420hp on stock turbos is impressive. What wastegate duty cycle are you running? Im at 380hp on my N54 and want to push further.

Nice numbers! I have a similar setup but running BM3 instead of MHD. Getting 415hp on 98 octane. The N54 is such a beast of an engine.

Index 12 injectors are a must for stage 2 N54. I was running index 7s and had fueling issues above 400hp. Swapped to 12s and problem solved.
