‘GReddy’ for the Supra: Modified Toyota makes big splash at US auto show

Kenji Sumino, president of GPP holds the award for the Best Supra at SEMA 2019.

The new 2020 Toyota Supra was a clear hit with the aftermarket community at the recently held Specialty Equipment Market Association (SEMA) trade show in Las Vegas, Nevada.

Over seventy of the cars were used as display vehicles at various vendor booths. From mild to wild, there was no shortage of quality and that made GReddy Performance Products Inc (GPP), the North American arm of Japanese performance giant Trust, a happy recipient of the SEMA Best GR Supra award handed out by Toyota USA.

“We got the car from Toyota and only started working on it late August, so with all that effort winning the first place in the best Supra at SEMA show it’s a great honour,” said Kenji Sumino president of GPP.

Their A90 Drift Concept also won the Super Street Magazine SEMA Ultimate Best of Show award for a second year.

GReddy’s A90 Drift Concept featured a 600hp engine and a manual transmission along with plenty of race spec custom parts.

“We only had two months to build it. The whole concept was to build a drift motorsports ready, Formula D track vehicle and to accomplish that in the two months was the biggest challenge,” Sumino said.

Sumino thanked his staff, partners, and the company’s drift program with Formula Drift driver Ken Gushi for their contribution to making the awards a reality.

The new Supra has not had a happy time, taking blunt criticism for its platform sharing with the BMW Z4, rather than being a bespoke Toyota product. The media and those who have actually interacted with the car have given it nothing but praise. At SEMA the aftermarket has clearly embraced the new Supra pumping out every possible modified variation one could think of. GPP is one of those who quickly moved to tune Toyota’s latest in response to what they believe will be another commercial hit as Supra deliveries increase. Rather than bolt-on parts, GPP took the Supra to its performance extreme making several custom parts, but ultimately using the car as a test bed for future products.

Rather than swap to the older Toyota 2JZ-GTE twin-turbo engine of the A80 Supra, GReddy tuned the BMW B58 motor in the new car.

Unlike many who have shunned the BMW B58 engine in the Supra, GPP showed what the motor is capable of. The inline six-cylinder has been boosted with a BorgWarner EFR 7163G turbo, custom intake and exhaust manifolds, GPP’s own intercooler, oil cooler and exhaust system. The result is over 600bhp to the wheels. Impressing judges was the manual transmission conversion as no factory manual version of the Supra exists as yet. The automatic transmission was ditched for a Samsonas sequential transmission and Tilton pedal assembly to add the needed clutch pedal. Suspension is handled by KW Motorsport and Wisefab. The interior is stripped to accommodate the motorsport seats, roll cage and gauges. On the exterior, Rays Wheels and a Pandem bodykit give the Supra some visual style.

Sumino explained that the toughest part of the build was the electronics as the Supra’s factory control system had to be replaced by a MoTeC engine management system from partner NCS in order to deal with the serious upgrades.
