CAMSHAFTS - STAGE 2 - 264 Spec (Toyota 1JZGTE)
The 2.5L Toyota 1JZ engine platform was produced from 1990 to 2007 (still in current production in the Mark II BLIT Wagon as the 1JZGE). Cylinder bore is 86mm x 71.5mm stroke. The 1JZGTE employs twin CT12A turbochargers from the factory, blowing through a side-mounted air-to-air intercooler. Features 8.5:1 compression, OEM power output is pegged at 280HP at 6200 rpm. The early 1JZGTE's are most commonly available with an auto tranny, but a 5 speed manual version was available in the Supra 2.5L GT. Yamaha is believed to have had a hand in the development and/or production of the engines, specifically cylinder head design. In the following year (1991), the 1JZ-GTE was slotted into the all-new Soarer GT. Output remained at 206kW/363Nm and, again, most examples come tied to an auto trans. These 1JZ-GTE powered Soarers are quite common on the Australian market (as 'grey' imports).
The 3rd gen 1JZ-GTE's introduced in 1996 feature Toyota's VVT-i technology. These cams are not VVT-i compatible.
Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances.
