Surprisingly, the 2JZ-GTE inline six runs factory stock internals. The valves and combustion chambers are also stock. The only additions in the valvetrain are HKS 264-degree bumpsticks and adjustable cam gears. The Paisley Supra is pressurized by twin HKS GT3037 turbos with Paisley-spec housings and other "tricks" performed to both the hot and cold side of the turbo. A HKS stainless-steel manifold positions the turbos and maximum boost is regulated to 26 psi via twin HKS wastegates and twin HKS boost controllers.
