Toyota Supra (MK4) Forced Induction FAQ's

Please read our FAQs page to find out more.

Keep the MK4’s factory twins or go single—what’s the trade‑off?

Factory sequential twins offer quick response and OEM manners but age out. A well‑sized single turbo simplifies plumbing and delivers stronger top‑end with proper fueling and tune.

What supporting mods are mandatory when raising boost on the MK4?

Fuel system capacity, intercooling, robust ignition, and a clutch/driveline that handles torque—plus ECU calibration matched to your fuel.

How do I size a turbo for my MK4 goals?

Define power target, fuel choice, and use case. Your tuner can map compressor flow to desired spool and top‑end so drivability stays intact.
