Remaining a bit late meant engineers could make the 2JZ far more strong than its resident counterpart. That resulted during the 2JZ acquiring an extended stroke, a lot more displacement, and sequential turbos, As well as its far more resilient non-interference layout.

A by-product of your RB25DET, the RB26 was released in 1989 and experienced its run right up until 2002. Unlike its predecessor, the RB26 makes use of a cylinder block without oil port and attributes an inline-6 format that has a Solid-iron block and aluminum cylinder heads.

While RB26 expertise and experience can assist using this type of, When the ECU is managing unique EGT sensors in Each and every runner on the exhaust manifold, it may possibly show if any cylinders are working lean. It may even the ECU to generally be programmed to automatically include fuel to any cylinder that gets noticeably hotter than Other individuals.
