FAQ
What makes this a “2nd-gen style” kit?The turbo is centered on the head using a T4 manifold (like 1994–2002 trucks), improving airflow and serviceability versus the stock 3rd-gen layout.
Is the downpipe included?
Yes, the kit includes a high-flow HX40 downpipe sized for the SX-E single setup.
Will .91 A/R tow well?
The .91 housing offers strong midrange and lower EGTs; for heavier tow rigs at altitude, consider the 1.0 A/R option listed above.
What other parts should I budget for?
An A/C reroute line, quality oil feed/drain, appropriate intake/charge piping, and a healthy lift pump help the turbo perform and live longer.
