What better option than factory? Instead of paying $400+ for an alternator in a Toyota box, we offer this same OEM alternator for a much more reasonable price. This specific listing is for the 90s style 3 pin oval connector. Please verify that you have this same oval style, and not the round 4 pin of most of the 2003+ UZ engines.

Please note these typically take 2-4 weeks MINIMUM to ship out

ATEMU simulates most critical features of particular Toyota / Lexus auto transmissions which were available for UZ / JZ equipped vehicles since 1998. This makes it possible to obtain rated power from engine when using factory ECU and any transmission other than that ECU is designed to work with. Factory ECU would otherwise enter limp home mode with significant power and torque loss (for example, VVTi set to max retard for 1998-2000 Lexus LS400) Some non-critical error codes remain intact for simplicity of installation and reducing the cost for off-road application. These codes can be easily addressed with additional components if emission test has to be passed for street legal application.

We now offer the additional resistor pack to wire in if you need to eliminate the check engine light (CEL)

APPLICATION: 1993-1998 Supra 2JZGTE (Turbo), 1JZGTE, and 2JZGE (Non-Turbo), IS300, GS300, SC300, etc.

PLEASE CHECK AND VERIFY (MATCH) THE PLUG YOU HAVE ON YOUR ALTERNATOR

This alternator is 100% plug n' play, direct fit, with no adapters, spacers or rigging like other kits. This is not a Sequoia alternator, which does require modifications to fit.

As you may know, the stock 1993-1998 Supra alternator provides 90amps/105amps (6sp/auto) of current flow at maximum output. When you install electric fan's, a cranking stereo system, and other electronic gadgets this presses the factory alternator to it's limits.

In some situations with the air conditioner running, electric fans going, dual fuel pumps, and more, there is simply not enough current to keep the battery at a constant state of charge. If you mix-in a large current draw from car stereo amplifiers, your electrical system will stop producing enough current, voltages across the system which drop to the lower end of the scale, and major issues can (and will) happen!

The last thing in the world you want is your aftermarket equipped 2JZGTE running big boost on multiple fuel pumps with all your other goodies on and then lose some current to the fuel supply! As Goose said to Maverick in Top Gun, "this is not good, Maverick."

We have looked for quite some time for an upgraded alternator that was robust, had increased current capacity, good-looking, cost-effective and would fit properly in the 1993-1998 Toyota Supra! Well, good news is that we have just the units! Our 155amp HOT RATE alternator kit is now available. The alternators are tested HOT, which means the output is guaranteed during typical automobile standard conditions. Most every other manufacturer releases their current ratings COLD, which can change the current output vs. hot by 10-15% simply on resistance losses at higher temperatures.

Fit and finish are excellent and it is a plug-n-play installation.

These units do not require a core charge. We usually stock these, but even if out of stock, build-time is only 72 hours. Six month warranty.

* Custom hand wound heavy gauge stator with high temp. insulation. Fully re-manufactured.

* Highest quality Internal electronic voltage regulator.

* Oversized bearings with high temp. grease for durability.

* Heavy duty rectifier plate with high amp diodes.

Our alternators are hot-rated, not cold-rated like all the other guys, which translates into, real-world amperage ratings.

These units are completely re-manufactured from original units (see above bullets for highlights)internals rebuilt and then the magic begins. As with any alternator they produce current based upon the coil windings and rpm's. The coil windings is where the current capacity is created, so it is based upon the capacity of the wire and number of windings on the coil.

Without over simplifying the process, we simply use a higher current (and more expensive) wire and provide additional windings inside the unit. The higher quality wire allows more current and heat to be handled, and the increase in quantity of windings increases the overall capacity. Then the internals are matched with higher capacity components for a matched-internal device with external results.

Bottom-line: you get a re-manufactured alternator, designed to produce more clean current then the factory original.

For 1JZGTE owners, this is NOT the 2JZGTE alternator, it is a 1JZ with the correct round 3 pin plug for the JZA70 Supra and is rated at ~140 AMPS. 50 more amps than you stock unit! If your 1JZGTE alternator is from a Soarer or Chaser, then please select the appropriate version from the drop down menu. 1JZ owners, please include what style connector your harness has, round or oval/rectangular

Application Note: This alternator will fit all 1993-1998 Supra Turbo and Non-Turbo Supra's, both automatic and 6 speed, Japan Spec, UK Spec, Euro Spec and US Spec. Direct fit, period.

International shipping: You will notice we have an international shipping option available in the drop down menu. While we cannot quote every country with this, it is good for much of the UK, Australia (eastern) and a few other nations. If you order the international option and for some reason the shipping is a bit more, we will notify you for your approval.

This plug and play tuner attaches to easy to access sensors in your Lexus engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.

For the IS200 power gains are up to 45 crank horsepower and up to 45 crank torque over stock, at the default map1 setting. With race gas or E85 mixtures, higher power gains are possible. Boost is adjustable using a BMS Data Cable or Bluetooth adapter. Includes fully OBDII based CANbus operation for unrivaled tuning performance, features, and functionality.

Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. A separate JB4 Mobile app purchase is also required.

Power gains of up to 100hp on a stock vehicle without the risks of flashing!

Units shipped 3/5/2021 or later include a free electronic wastegate (EWG) connector preinstalled in the JB4 harness!

The JB4 is the most advanced and highly featured tuning system available for your Toyota Supra Mk5. Power gains are up to 80hp to the wheels (100hp crank) on a completely stock car on pump gas for a B58, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher.

The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.

Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter.

Note we have not developed the in-dash commands yet for the JB4 Supra. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable.

Drop in, plug-n-play, rebuilt OEM Toyota 150 amp alternator to fit your UZ! Fits all UZ engines, and bolts right in without any modifications. Don't settle for a poor quality rebuild from whoever has it cheapest. Opt for the best, for years of trouble free operation! Please note that some UZs have the connector in a different location, so you will need to verify your application has the connector that comes straight back out of the back of the alternator, and not plug in on top with a 90* angle.

We also use these on our GZG50 V12 Centurys!

These use a 4 pin connector, but we include the plug-n-play adapter with every order, so no extra work required! 100% ready to go

This alternator also has an extra mounting rib that newer UZ engines added, however this is not required for mounting, does not get in the way, and does not need to be machined off in most cases. Some fitments will require this

Please note this adapter harness only works on UZ engines with the oval style connector. If you have the round connector, you will have to rewire your harness for this to work, which is fairly straightforward since it's only 3 wires. 

You will also need to verify that your plug is in the same position as the picture on your application. Some applications do not have room behind the alternator itself to plug in, and instead have the plug radially mounted instead of axial mounted. We do not currently have a replacement option for that.
