For starters, all versions of the 2JZ uses a cast iron block. That’s not great where weight is concerned, but for ultimate strength, it’s ideal. Points out that the 2JZ is a closed-deck engine, which means the cylinders themselves are quite strong. This is why the 2JZ-GTE can handle a ton of turbo boost pressure. You can force a lot of air through those cylinders without having to worry about the basic structure of the engine.
The 2JZ-GTE also benefits from a well-designed three-layer steel head gasket that can withstand high boost pressure without blowing. Then, there’s the forged steel crankshaft, which is particularly strong, and helps build rigidity to the engine
Essentially, Toyota went completely overboard when designing this engine. It shares a lot of design characteristics with a high-compression turbo-diesel truck engine, but it’s a gas-powered sports car engine. It’s almost as if Toyota designed the 2JZ with boost-hungry tuners in mind from the outset.
When you can take a humble 3.0-litre six-cylinder engine, leave the bottom end completely untouched and crank out over 1,000 horsepower with nothing more than a turbo and some big injectors, you know you’re working with a absolute beast of an engine.
The iron block, closed deck, inline six design was built to handle enormous power in its stock form. 700hp to 800hp can be supported with just a single turbo conversion, upgraded fuel and tuning.

RB26 / RBD26 DETT
It’s a Nissan Patrol. RB stands for Race Bred. 25 stands for displacement. D for double overhead cam. E for fuel injection. We’re huge fans of Nissan’s RB engine, and the RB25DET is best known for being in a variety of Skylines,
Nissan released its Skyline GT-R for the first time since 1973 with the BNR32. Designed with high performance and racing in Group A competition as its primary objective, Nissan engineers equipped the Skyline with the largest and most powerful version of its RB engine series, the RB26DETT. The inline six-cylinder engine is based on an iron block and an aluminum cylinder head. The RB26DETT featured a relatively short 73.7mm stroke that permitted high engine speeds. The stout RB26 block was also available in an N1 variant for N1 endurance competition, which featured additional ribbing for strength. The third and most valuable version was the GT block.
