British tuner dials the new Toyota Supra up to 425 HP

Just a week ago, Florida-based tuner Titan Motorsports released an ECU tune for the newest Toyota GR Supra (A90), pushing its power to 400 hp (300 kW). A couple days ago, British Litchfield Motors followed up with their own upgrade kit.

The kit – which you will be justified in calling ‘Stage 1’, since nothing has been done with the engine hardware – manages to squeeze an additional 85 hp (63 kW) and 75 Nm (55 lb-ft) of torque from the stock 3.0-liter twin-turbo V6. The result is a respectable 425 hp (317 kW) along with 575 Nm (424 lb-ft) of torque – a fair bit more than what Titan Motorsports offers.

Litchfield Motors’ future plans for the new Supra include designing a new lowering kit, a few other suspension parts and a couple carbon body mods.
