FAQs
Will this work with stock fueling?Yes. It’s designed to pair well with stock to mild fueling upgrades. For best results, add a quality intake and ensure your exhaust and intercooler plumbing are leak-free.
Do I need an HX40 downpipe on 2003–2004 trucks?Yes. All 03–04 PhatShaft 64 applications require an HX40-style downpipe. See the required part link above.
What power range can this support?With proper fueling and airflow, the PhatShaft 64 commonly supports about 350–600 HP while keeping EGTs in check for towing and spirited street use.
Is this the right housing for towing?The 12cm turbine housing gives quicker spool and strong low-RPM response—ideal for daily use and towing. If you prioritize top-end, consider the 14cm variant.
