Frequently Asked Questions

Do I need an ECU tune after fitting this turbo?
Yes. A professional remap is strongly recommended to set safe boost, rail pressure, and fuelling targets, and to get the best performance.
Will it bolt to the factory 4JJ3 manifold and lines?
Yes, it’s designed for the stock 4JJ3 manifold pattern. You’ll reuse most factory locations; minor oil feed/drain and intake/exhaust tweaks may be needed depending on your setup.
What supporting mods are recommended?
Upgraded intercooler, high-flow intake and exhaust, appropriate injectors if targeting the upper power range, and accurate boost/EGT monitoring.
Does this suit 4JJ1 models?
This listing targets 4JJ3 (2020+), and it can be adapted to DPF 4JJ1 models with a custom exhaust. Message us with your VIN for the correct 4JJ1 options.
What boost should I run?
Typical tuned setups see ~30–35 psi. Higher targets up to ~40 psi are possible on well-supported builds—always follow your tuner’s guidance.
