FAQ
How does 1.10 A/R drive compared to .90 or 1.0?1.10 A/R favors top-end flow and lower drive pressure at high RPM. The .90 A/R spools faster but can build more drive pressure; 1.0 is the middle ground.
Do I need bigger injectors?Yes—this kit requires injector upgrades for proper spool and power. See our 03–07 injector options linked above.
Is tuning required?Custom or performance tuning is strongly recommended to optimize boost, fueling, and EGT with a large S400-frame turbo.
What else should I upgrade?Head studs, a healthy lift pump/CP3, quality boost/EGT monitoring, and correct oil feed/drain routing improve reliability with big singles.
