FAQ
How much airflow gain does BBT provide?The BBT58 billet compressor wheel is noted by Industrial Injection for producing up to about 10% more airflow than a similar cast wheel, improving response and overall efficiency.
Is tuning required with the Boxer 58?Many installs run well on stock tuning; however, calibration updates can maximize spool, EGT control, and power—especially with added fueling or other airflow mods.
What downpipe do I need?The kit includes an HX40-style downpipe and clamp. If replacing or fabricating, select HX40-compatible parts and clamps to match the turbo outlet.
What supporting mods are recommended?Head studs for sustained boost, intercooler/boost-tube upgrades to lower EGTs, a high-flow intake elbow, and proper boost control for consistent drive pressure.
