So you’ve copped yourself an awesome IS300 which has served you well, but the time has come to consider the potential of using your 2JZ-GE to its full potential? We’ve got you covered!

Sure, you’ve probably lusted after the Supra’s infamous 2JZ-GTE, but with ever-growing prices and with them becoming increasingly hard to find, tuning companies have worked to achieve a sensible compromise with your GE. If money isn’t an issue and one is available, a GTE swap may well suit you best.

However, we’ve written this article for those of you that are ready to give your IS300’s engine some much-needed boost with this reasonably priced forced-induction addition, it’s time for some NA-T fun!

If you’re worried about the strength of these engines, be reassured that most of the parts are shared with the GTE, which is capable of 1,000whp. The rods and crankshaft are identical, with the pistons being the only internal variation between these engines, which were made with turbocharged intentions from the factory.

With that being said, there are still considerable differences between the two power plants. There’s a different style inlet manifold, compression ratio, injectors, sensors, and exhaust manifold and many other variations to consider. This, of course, means that simply bolting GTE turbos to a GE engine wouldn’t be as straightforward as most owners would like!

We’ve written this guide to explain the differences and help you decide which of these off-the-shelf turbo kits best fits your needs.

Take a ride with The Weekend Driver as they get behind the wheel of a 550hp single-turbo 2JZ to see what the GE engine is truly capable of once it’s been fitted with turbo goodness!

Let’s take a look at our IS300 turbo kits

CXRacing IS300 Turbo kit

Our comment: Frequently regarded the best off-the-shelf bolt-on solution, this newly designed kit provides great quality at an impressive price. Featuring a well-made manifold with good-quality welding alongside a highly-regarded intercooler and piping. It includes a GT35 turbo and also offers a ball bearing upgrade for an additional $200. Alternatively, if you’re looking to use a different turbo and wastegate, you can save $220 on this package. Many owners have successfully run this kit for several years on high-mileage GE NA-T engines with nothing but praise.

Manufacturer description:Brand NEW Design of Top Mount T4 GT35 Turbo Manifold with Equal Length and Long Tube Runner Design, Supports Bigger HP and Higher Torque.”

“This is CXRacing’s Newest Product for the Application Stated Above. All Parts Are Developed from Ground Up in Our R&D Center in USA, Designed and Built for Improved Performance Gains, with Excellent Fitment and Easy Installation.”


XS Power IS300 Turbo kit

Our comment: This may initially seem far cheaper than the CXRacing kit, but their price doesn’t include the FMIC piping or fuel tuning device. That being said, this is another fantastic, newly revamped kit to compete with CXRacing on the market.

XS Power are very highly regarded within the 2JZ scene and this kit has been popular with many IS owners over the years as they racked up thousands of miles with very few issues.

Manufacturer description:Your stock GE motor makes 180WHP on a good day. The stock GTE motor puts down about 285WHP if the stock twins are in great shape.”

“Install this XS-POWER 2JZ GE / GTE turbo kit and boost to 9PSI on stock internals, head gasket, and injectors. You’ll be putting down 330WHP. No need to open the motor or mess with the injectors or tranny at 9PSI, just run 93 Octane and a fuel tuning system.”


Driftmotion IS300 Turbo kit

Our comment: Another popular offering to the market is Driftmotion with this good quality offering which features Garrett internals. We’ve found mixed opinions on this kit with some people saying that modifications have been needed to ensure a perfect fit, which means it’s not really a ‘bolt-on and go’ affair. There are reports of a weak wastegate included in the kit, so perhaps source your own alternative. This price does not include the FMIC or piping. Various turbo options are available, all the way up to 750whp.

Despite many positive reports, Driftmotion have also apparently been hard to contact when issues arise.

Manufacturer description:2JZGE NA-T 60-1 Turbo Kit. Capable of over 550whp. Kit includes manifold, wastegate, 4″ intake pipe, dump tube, fasteners, oil lines and fittings, gaskets, adaptor flanges for turbo and block oil lines, 60-1 turbo with ceramic coated exhaust housing and polished compressor housing, blue anodized billet backplate, all Garrett internals.”

We’re confident that this is the best kit on the market for the money. A 4″ K&N filter is now included with the kit! The kit will not fit a right-hand drive vehicle without modification to the wastegate piping.”


Turbonetics IS300 Turbo kit

Our comment: The most expensive kit in our list has been around for quite some time. Although some owners have had success with it, there also seems to be a lot of reports of issues. For the price, we can’t justify the added value over the cheaper kits above.

We have also heard reports of the kit being discontinued, so if you feel it is the right choice for your needs then we strongly advise checking this. Getting spare parts for a discontinued kit can be very frustrating.

Manufacturer description:Turbonetics Turbo Systems are for you, whether you have a four-cylinder sport compact or a V-8 muscle car, Turbonetics Turbo Systems include everything you need from fuel and ignition to piping and fittings for complete bolt-on turbo performance.”

“Turbonetics offers complete turbo systems – from air entry to exhausting to the catalyst. The Turbonetics Turbo System is a true O.E. bolt-on that does not require “hacking” in order to install.


Turbo Specialties IS300 Turbo kit

Our comment: Turbo Specialties enter our list with the second most expensive option so far. This kit was one of the first IS300 kits to ever be released and was the main competitor of the SRT (Swift Racing) kit, however, SRT has since gone out of business. Although the kit includes a Garrett turbo, we’re not entirely convinced that the T28R is the ideal turbo for boosting your IS300, and there are definitely more suited options in our selection.

Combine this with the fact that most owners have mentioned that the kit needs some adjustments to fit correctly, we can’t justify the cost compared to some of the substantially cheaper alternatives on the market.

Manufacturer description:If you are looking for the ultimate in high-performance – the extreme performance packages are for you. Providing the maximum horsepower for the very discriminating and still providing dependability for daily driving. Incorporating all the high performance equipment in the superior performance packages, these extreme packages all include an intercooler, pop off valve, extra injectors, and injection control unit, (The Brain).”

“This offers complete control for your system, increased fuel delivery, and cooler temperature gas-air mixture for better burning. The addition of this system can add as much as an additional 20 percent increase in horsepower above and beyond the superior turbo packages.


FastWayRacer IS300 Turbo kit

Our comment: It’s certainly not every day that you stumble upon a turbo kit that is up for under $1,000 brand new, but FastWayRacer have pulled it out of the bag with the cheapest option on our list.

Unfortunately, there is very little to go on with regards to good or bad reviews on this system, so we highly recommend checking that it suits your needs before going ahead. Cheap isn’t always cheerful, especially when things start going wrong!

Manufacturer description:This is a perfect turbo kit for upgrading your car and get more boost. Your car will gain 130-180HP if you set at 7-15PSI. Customers require to upgrade the fuel pump, injector and ECU to tune the car if you set at higher PSI. This kit can max up to 550HP. We offer 90 days warranty for this turbo kit if it is installed by ase certified mechanic! We also offer “FASTWAYRACER” license plate and “FASTWAYRACER” sticker for free!”


Our winner

Our winner is the CXRacing Turbo kit.

To pick our winner from this choice of IS300 turbo kits we looked at a number of criteria; ease of installation, quality, popularity, upgrade potential and price point.

Based on these criteria we have chosen the CXRacing Turbo kit to be our winner.

CXRacing IS300 Turbo kit

With no big name brands stepping up to the plate in the 2JZ-GE tuning scene, it left a great opportunity for some smaller brands to take the win this time around.

If you perhaps don’t feel comfortable running the turbo or wastegate supplied within these well-priced kits, and want to go for something more reputable or powerful, it’s worth considering the CXRacing option without the turbo and wastegate.

The manifold, pipework and the rest of the CXRacing kit all have a great reputation, so fitting a fancy turbo and wastegate could well be the perfect answer.

If CXRacing doesn’t suit your preference, we’d definitely recommend considering the XS Power option.
