I'd like to do away with the hydrofan control box and I'd like to be able to add more functionality to the fan. So does anyone know how the pressure solenoid is controlled? I assume it is powered by some PWM signal. But how? Voltage (12 V?), polarity (which pin is what?) , duty cycles (range...

I recently bought a HKS Tems controller and since my car is EURO spec and didn't come with TEMS I have wired it in myself a few years ago. And it works fine. But since I did that I don't have the O1 plug / connector where the HKS TEMS controller plugs in so I have to hardwire it in mostly at...

I just found out that according to several websites that Horsepowerfreaks have gone out of business. I ordered and paid for a new torque converter on february 13 2013. They waited until march 1st, when I contacted them asking when they were shipping it out, before they contacted me and told me...

I'm finally wiring in my PCS transmission controller, but I have a few doubts about certain sensors. One of them is the Over drive direct clutch speed sensor which is on the A340 from the MKIV supra. Does anyone know how many pulses it detects per revolution of the over drive direct...

I have error code 41 and the car runs in limp mode. I have a 2JZ-GTE engine in my mkIII. When reading the TSRM it states that an unplugged connector will not set the code. Only faulty circuit, TPS or ecu regarding the VTA circuit will. When I unplug the TPS the code remains. When reading...

I just bought a new right hand side rear moulding from Toyota and it doesn't look like the original at all. The profile of the small lower part (the inserted rubber) is totally different from the original one. What is going on?

Going to do the suspension this winter and I'm wondering how the kits from Ronnie K and Energy Suspension compare. Ronnie makes different kits in terms of hardness. How does the Energy Suspension kit compare to the RK kit (RED / YELLOW / ?) in this regard? Does anyone have an oppinion on the...

I have a little bit of play in the steering wheel. Not much but it is very apparent at speed - makes me constantly adjust the steering wheel. I think it comes from the rack (after changing the different other parts of the steering column). It is driving me nuts. I've been told that the...

I'm trying to configure a traction control system and I need to know how many pulses the front wheel ABS sensors pick up pr rotation of the wheel. I know that the rear sensor gives 32 pulses pr rotation of the driveshaft. Does anyone know how many pulses for the front sensors?

I have swapped in a 2JZ-GTE into my mkIII. I used to use the mkIV automatic transmission with a custome drive shaft. It was noisy so I exchanged the transmission for a 1999 Soarer A340. It has the same plugs for the valve body as the JZA80 transmission so the stock JZA80 ECU it can actually...

What are the differences between the stock JZA70 and the MA70 motor mounts? They have different part numbers: JZA70 : 12361-46040 http://www.toyodiy.com/parts/p_J_1993_TOYOTA_SUPRA_JZA70-BJPVZ_1107.6.html?hl=12311 MA70 : 12361-42050...

I was wondering how to control the sub-throttle stepper motor on the 2JZ-GTE. I have done a 2JZ swap into my mk3. I want to see if I can use the sub-throttle stepper motor to control traction and reduce the stress on the automatic gearbox between shifts. So does anyone know how this thing...

I just finished my 2JZ-GTE swap. The engine was fired up at 2 am. Started in the first try. Yeah !!! My car is a 92 mk3 and I was wondering if the stock fuel pump is adequate for a stock 2JZ-GTE with 330 hp? I have a Walbro pump here, just don't know if it is needed.

Has anyone been able to wire in the cruise control actuator from a JZA80 into the MA70? Looking at the diagrams it seems they both have similar number of wires. The mkIII has 8 wires with a double ground and the mkIV has 7 wires with a single ground. I'm doing a 2JZ swap now and I need to...

I have a mint JZA70 MOMO steering wheel that I'd like to put on the car but it doesn't come with buttons for cruise control. Does anyone know of a boss kit currently made that'll allow me to retain cruise control and use the MOMO wheel with the center piece? I seem to remember someone...

I'm changing the rod bearings on my 2JZGTE before dropping it in. I bought some ARP rod bolts and reading the instructions it tells me to torque it down using some kind of device to measure stretch. I don't know how to do that. If I can't do that then they tell me to torque it to 50 ft/lb...

I'm doing a 2JZ swap and I'm right now in the process of changing the rod bearings. What I see from the crankshaft is 1 1 1 1 1 1 (first to 6th cylinder) The rods say: 2 3 2 2 2 2 (first to 6th cylinder) So I assume the bearings I should use are: 3 4 3 3 3 3 When I take the rods...

What would it take to mate a A340 from a MA70 to a 2JZGTE from a JZA80 and would it be possible to swap over the valve body from the MKIV TT autotransmission without any modifications? I'm thinking this might be a way to retain automatic transmission without the need for a custom drive shaft...

I need to know how many revolutions the speedometer drive makes pr. revolution of the drive shaft on a 1992 car which I assume has a 3.727:1 diff.
