FAQ
What kind of driving is a 63/68 1.0 A/R best for?Great all-around street/strip setup with quicker spool than larger SX-E options and strong mid-top power. Ideal for 500–600+ HP builds with appropriate fueling and tuning.
Does this kit replace my stock 3rd-gen location?Yes. It’s a 2nd-gen-style center-mount conversion on a T4 manifold with an included HX40 downpipe for proper fitment.
Do I need head studs?Head studs are strongly recommended as boost and cylinder pressure rise with increased airflow and fueling.
Is tuning required?While the charger can operate on stock calibration, custom tuning is recommended to fully optimize spool, EGTs, and drivability.
