Since the 2JZ-GE runs at 10:1 compression, we don’t recommend going above 7-8 PSI of boost before you begin having to adjust things like ignition timing. Other significant variations between the two engines include the injectors and airflow sensors, the ignition system, and the port spacing and studs on the manifolds. The GE manifold is designed to provide the most torque possible to make up for the lack of forced induction, which assists in the lower bracket of the RPM band.īoth heads are slightly different, with the GTE having larger intake ports, and the GE having larger exhaust ports, which has led some enthusiasts convinced that the GE head is capable of flowing better than the GTE head. GE’s have a 10.0:1 compression ratio, compared to the 8.5:1 of the GTE, due to a thicker head gasket (.2mm for GE, 1.6mm for GTE) and lower-compression pistons in the GTE. One of the main differences between the two engines lies within compression. This factory-turbocharged equivalent of the naturally-aspirated 2JZ-GE engine has earned legendary status and has become quite possibly the most desirable engine within the drifting and drag racing scenes worldwide. Since you’re already reading this article, you’ll undoubtedly know about the legendary 2JZ-GTE, most notably found in the MKIV Toyota Supra.

We’ll cover the full range of products that we feel are worth considering, from budget through to premium, to help you find the perfect NA-T turbo kit to help you make the most out of your currently underachieving 2JZ-GE engine. There’s an influx of cheap ‘Chinese’ knock-off kits on the market, and although these may work fine for some owners, we’re more interested in the companies committed to putting their names to their setup. We’ve seen setups of up to 1,000 WHP achieved from the stock 2JZ-GTE bottom-end, and we’ve also witnessed a GE run a 9 ¼ sec quarter-mile from a motor with 220k miles on the clock!Īlthough there’s no shortage of turbo kits for the 2JZ-GE engine, it can get a little confusing when you’re looking at the options on the market, so we’ve written this guide to clarify which kit(s) will be best for your needs.
So, despite being naturally aspirated, Toyota designed both 2JZ engines with forced induction in mind and they’re both up there with the most robust stock blocks that money can buy.Īlthough the pistons are different, they’re still more than capable of handling respectable power figures, and it’s not until you go chasing huge numbers that you’ll maybe need to consider opting for forged pistons. Thankfully, the 2JZ-GE is incredibly similar to the GTE, integrating the same rods and crankshaft, with the discernable difference between the two powerplants falling to the choice of pistons. The 2JZ-GE often gets overlooked for its more impressive sibling, but with ever-rising prices of the 2JZ-GTE, it makes more sense than ever for the GE engine to get the turbocharged lovin’ that it deserves. Sure, your 2JZ-GE isn’t going to feel like the much-loved 2JZ-GTE in stock form, but with an NA-T turbo upgrade, you’ll be amazed at how quickly and effortlessly you’ll be able to achieve some impressive power figures. Whether you’ve purchased yourself a Toyota or a Lexus with the underrated 2JZ-GE engine under the hood, you’re most probably already aware of what the 2JZ can achieve.
