APPLICATION: 1993-1998 Supra 2JZGTE (Turbo), 1JZGTE, and 2JZGE (Non-Turbo), IS300, GS300, SC300, etc.
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.
If you want a polished alternator housing (like shown in picture) please select that from the drop down menu for an additional $145.
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.
