N52 vs N51 — what's the difference? +
N51 is the SULEV variant with lower compression, extra emissions components, and tune. Most of our parts fit both.
How much power do the supercharger kits make? +
Our ESS-based N52/N51 kits come in Base, Stage 2, and Stage 3 — each with tuning, 60# injectors, and matched spark plugs. With supporting mods they make anywhere from 300 to 500whp+, depending on pulley, fuel, and methanol. We charge a $125 consultation deposit to spec the right kit for your goals; it comes off the final price.
Do you ship internationally? +
Yes — DHL Express tracked worldwide. Customers in 38 countries and counting.
Don't guess.
Build a faster N52.
