🧠 FAQs (Quick Glance):

Q: Why Stage 2?
Stage 2 is built for high-horsepower big turbo or fully built engines. Stage 1 kits were discontinued due to limited performance potential compared to Stage 2.

Q: Why more HP on 93 than E85?
Gasoline has more energy per unit than ethanol. Even though E85 enables more boost, our fuel system capacity numbers reflect potential output assuming ideal conditions.

Q: Can you make N54 injectors?
No — N54 uses piezo-electric injectors, which are not currently upgradable with our methods.

Q: Why is spray pattern important?
Proper atomization = better combustion = more power, better drivability, and reduced engine wear. Nostrum’s OEM-equivalent spray pattern keeps things clean and reliable.
