FAQ
What power range is the S471 .90 A/R good for?Suitable for strong street/tow & weekend track builds when paired with adequate fueling, air, and head retention. Injector and pump upgrades are recommended for best results.
Will this bolt to my factory manifold?No. This is a 2nd-Gen swap kit using a T4 divided housing; use the included swap components per the kit.
How does .90 A/R compare to 1.00 or 1.10?.90 A/R generally offers quicker response and lower EGTs at moderate power; 1.00/1.10 A/R typically support higher peak flow with later spool. See the Alternatives above.
Is tuning required?Custom calibration is strongly recommended to optimize fueling, wastegate/boost control, and transmission behavior for the larger charger.
