Genesis · G70 · G70 (2018+)

It's a Kia Stinger underneath

The 3.3T G70 shares its M2 platform and Lambda II 3.3 twin-turbo V6 with the Kia Stinger GT — same engine, same eight-speed auto. That's good news for tuning: most Stinger hardware and tune knowledge carries straight across, so the G70 punches well above what its sales numbers suggest in terms of aftermarket support.

FAQ

Common questions

What's the best first mod for a 3.3T G70?

A proper ECU tune. The Lambda II twin-turbo responds very well on the stock turbos, and the eight-speed auto can be tuned alongside it for crisper shifts. After that, an intake and a catback or downpipes are the usual next steps.

What sort of gains are realistic on stock turbos?

A tune on 98 RON typically lifts a healthy 3.3T well past stock, with the bigger felt difference coming from torque and throttle response in the midrange. Downpipes plus a tune push it further again; the factory turbos are the ceiling before you go to a hybrid turbo upgrade.

Do I need to worry about parts availability being a Genesis?

Less than you'd think. Because the drivetrain is shared with the Kia Stinger, a lot of intakes, exhausts, intercoolers and turbo kits developed for the Stinger 3.3T bolt to the G70, so the aftermarket is far deeper than the Genesis badge alone would suggest.

Are there known weak points to plan around?

The 3.3 has had turbocharger reliability cases (often the right-hand turbo) on higher-km cars, so it's worth checking before adding boost. The eight-speed auto is strong but benefits from a transmission tune and fresh fluid if you're chasing harder shifts and more power.
