KEY FEATURES

Hybrid VNT/VGT turbo with vacuum actuator – responsive, low-lag control.
High-flow wheel set (larger diameters) to increase mass airflow and sustain boost at load. (In line with reputable 1HD-FTE performance upgrades.)
Designed for HDJ80/HDJ100 conversion or upgrade applications; no new exhaust manifold typically required on bolt-on kits for 1HD-FTE.

SPECS

For 1HD-FTE (HDJ100) running >~1.0 bar, use a MAP emulator (EMUMAP) to prevent ECU protection.
For conversions from non-VNT setups, plan on an intake elbow/adapter, 3" downpipe, suitable oil/water lines, and ideally a larger intercooler.
Intended boost range: Stock→high with proper fueling and EMUMAP strategy on 1HD-FTE.
