PHR/Tilton Hydraulic Release Bearing Kit for Spec Twin/ Mini Triple disc clutch



If you have a Spec Multi-Disc Clutch for 6spd Supra, you need to look at the problems they have been having with their hydraulic release bearings.

We decided to dig into this after having several customers have their release bearings fail on the spec mini triples. I've recommended this clutch many times and we think the clutch itself is a great clutch... however the release bearings are a big problem. Every single one has failed. This one in particular is from a customers 6 speed supra



As you can see in the picture, the orings are rotted. This is not from wear. This is from the clutch fluid literally eating the o-rings. Spec, or whoever builds these release bearings for them (clutch masters appears to have the same bearing, China perhaps) is using the wrong material in their orings. The orings are not compatible with normal type brake fluids (dot3, dot5).

Of course this failure will only happen after the release bearing is out of warranty. (120 days). It takes a little time before the o-rings will be eaten to a point of failure.

Spec should be able to offer quality product they can stand behind, and I'm sure they don't stand behind this.

Here is the solution to the problem. PHR is now offering Tilton slave cylinders and adapters to work with the Spec mini triple clutch. We are fairly certain these will work with the Spec twin disc as well but have not confirmed.

So if you have a spec clutch with their hydraulic release bearing, u need to get this setup before u have a failure on your hands.

Do NOT buy Spec clutches for your supra unless you also purchase the PHR/Tilton Hydraulic Release Bearing Kit. Together they are a good combination, but without the tilton release bearing it is an imminent failure.



PHR Ford IAC Adapter Kit for 2JZ-GTE

Finally, a solution to the 2JZ-GTE idle motors. Factory stepper motors require 4 wires to operate. The PHR Ford IAC Adapter Kit for 2JZ-GTE only requires a single output from your ecu, freeing up 3 additional outputs. This is extremely helpful on ECU's like MoTeC M600, M84 and other where outputs are limited. If your ECU is limited on outputs, this is the solution you need to free up your outputs for other needs.

In addition, the factory idle motors are extremely expensive to replace and are very difficult to find used in good condition. This provides an affordable alternative for those running aftermarket ECU's when their idle motor fails.

Can be run with a filter attached directly to the IAC or 3/4" hose to the intake pipe or other location for IAC filtration. You will need to continue using the factory check valve, grommet and gasket to keep from leaking boost. Only replace the motor and housing.

PHR is continuing to bring solutions to the 2JZ-GTE platform, and are proud to offer this one.

New From PHR! PHR Mechanical Fuel System for Toyota Supra

 The Powerhouse Racing Mechanical Fuel System for the 93-98 Toyota Supra is the absolute ultimate in fuel systems. There is nothing that compares in quality or capability anywhere on the planet. Made specifically to address all of the fuel system needs for HUGE horsepower Toyota Supras, this system can support over 3000hp on Gasoline, Ethanol and even Methanol.

With three different Weldon fuel pumps to choose from, you can tailor the kit to your specific needs and future plans. Although the system is made to support massive hp, pairing a smaller pump and injector setup is perfectly fine for even street-driven cars. The mechanical pump is virtually silent on the front of the motor so you don't have to listen to the whine of big electrical fuel pumps.

Add the priming pump for easy, trouble-free starting. The priming pump pressurizes the fuel system before and/or during cranking to keep the mechanical pump from starving for fuel. This makes starting the engine quick and painless.

Teflon core fuel lines are compatible with all fuel types so no matter what fuel you are running, you know that your lines are capable of doing the job.

PHR Billet LQ9 Coil Brackets for 2JZGTE, 1JZGTE

PHR now offers a great solution for mounting your LQ9 coils into the 2jzgte/1jzgte. These brackets are made from billet aluminum and offer the best and easiest way to mount your coils into the coil galley. Easily serviceable and installable. Makes spark plug changes a breeze and you no longer have to fumble around with trying to get the coil to sit right. You never have to worry about an insecure coil or worry about them rattling around in your high horsepower motor.

The coil mounts directly into the bracket and then the brackets are bolted over the spark plug.

PHR also offers brand new coil boots and/or brand new coils to be included as an option.

The LQ9 coil provides immense energy for firing coils and are far superior to the stock coils. We have seen these coils work at over 1500hp, and still have not seen the limit of them. These are easily the least expensive route to extreme spark energy. The ignitor is built into each coil so you no longer need the factory ignitor mounted on the strut tower.

*coils do not provide an IGF signal back to factory ECU, so you will need a standalone ecu, or a solution like and IGF signal generator/faker or MAP ECU 3 which provides an IGF signal.

*Works only with NON-VVTi motors
