These are the basics, but a front mount intercooler, one step colder plugs gapped a little closer, and an AFR gauge to make sure your fueling is safe when on boost, are also wise additions at this level. This generally consists of a full turbo back exhaust system, a boost controller, and a little box of tricks, often known as a FCD, to manipulate the signal to the MAP or MAF sensor (depending if you own a JDM model or not) to prevent the factory ECU from cutting power when you increase the boost level. It brings you to around the maximum the factory turbochargers are capable of. Boost Pressure Upgrade, this is the traditional and well-proven tuning method for an otherwise standard 2JZ-GTE engine. This is great not only for reliability, but to make sure you’re not starting on the back foot with less than standard power.Ĭommonly known as the BPU, i.e. The basics of Toyota 2JZ-GTE tuning, the BPUīefore you go wild chasing big power numbers, the first thing to do is make sure the engine is capable of making standard power these engines are 20 to 30 years old after all! An overall health check fresh cambelt tensioner and water pump, oil and filter change and ideally a smoke test to make sure there’s no boost leaks, are all very wise moves before you start. Every single incarnation of the 2JZ-GTE has the potential to make hypercar beating power levels with relative ease. However, in the grand scheme of things, they’re all fairly insignificant. Technically, the export market versions have a few more minor upgrades that the Japanese ones did not. That’s how it stayed up until the end of production in 2002.Īside from the cylinder head change, there are some minor turbo changes between versions. First produced in 1991, the only big change was in 1997 when the VVTi version added variable valve timing to the mix. From the factory it came in certain versions of the JZA80 (aka Mk4) Supra and JZS147/JZS161 (aka Mk1+2) Aristo. ![]() The 2JZ-GTE is an iron block, three-liter, inline six cylinder, a twin cam 24 valve cylinder head, and twin sequential turbochargers. And guess what? We’re here to show you how to tune 2JZ-GTE and unlock its full potential. All from an early 90s engine that left the factory with 320bhp or less. There are 2JZs that have ran 5sec quarter miles others that have done over 330mph. The Supra GT and LeMans race cars didn’t run 2Js! For reasons we may never know, Toyota wildly over-engineered the engine, meaning the tuning potential is absolutely incredible. To most modified car fans it has an almost God-like status among engines.īut is that status justified? Yes! This is an engine that, unlike most other great engines, doesn’t come from a motorsport background. Toyota’s 2JZ-GTE has been one of the best known engines in the car tuning scene for the last couple of decades. With over 2500bhp possible, we show you how to tune the over-engineered 2JZ-GTE. The Toyota 2JZ is a legendary engine of the modern tuning era.
