Damn man, your thread is AMAZING. The way you rewired your knock sensor is just... well, beyond me, haha. Absolutely awesome thread, this should be stickied.





Oh, awesome car, too.

Thanks a lot man! i was wondering because my freakin heater wont turn on for some reason, the buttons and dial on the climate control work but no air blowing.........im stumped

if it's that then it's probably you're blower motor. The only thing related to the pic is the heater control valve, located at the top of your pic (above the ABS actuator). FYI don't do this in other people's threads, it's kinda rude.

I went ahead and removed the R154/BoostLogic driveshaft and JDm 3.26 Supra differential.

I installed the W58/stock driveshaft and the 4.08 diff with a Fidanza flywheel and Competition Clutch stage4 unit.

I'll probably be swapping out the 4.08 for an Sc400 3.92 diff maybe this weekend.

I'm thinking the 3.92 Differential gearing will be ideal with the W58/R154 gearing.

**the R154 and W58 cross member brackets are exactly the same, but are reversed when mounted to the chassis**







i had to loosen the engine mounts and slightly tilt the front of the engine up to get to the top 2 bellhousing bolts using about 4 foot of extensions, lol! ohya that jackstand is just there as a safety net...I have like 6-7 jackstands jacks under the car at all times...

Wow, that was a lot of work! Why are you going back to the stock driveshaft and rear end?

both tranys look a like, what year is the w58, that is the one you are installing? also the competition clutch is push correct? can you take more pics on the pressure plate, part number and price, and flywheel, I am in the process in replacing my clutch in my 1jz with w58 but mines is different. on the shifting part.

2 questions for ya Ryan. One, how do you like the transmission jack? Second, how long did it take you to remove the trans? I am about to do this on Sunday and would just like an idea.

My Supra TT 3.76 works quite well with the R154 gearing. The old 4.2 auto diff was way too short.

This is correct.

The gearing between the W58 and R154 is almost identical. Therefore either transmission could be made to "feel" correct with either the NA 5SPD differential for NA applications or a TT Auto differential for FI applications.

I recently found out that my 'auto supra' torsen differential is actually the 3.26 JDM Supra differential.

I agree the 3.76 torsen would be very nice.

I am going to go ahead and try the 3.92 differential because if I can knock off 500rpm in 5th gear@60mph it would be ideal for what I use the car for.

That would increase your RPM over what you had previous.

The jack is garbage and actually broke during this job. I'd get the better one that looks more like a car jack.

You can remove the trans in under 7hrs if you are prepared with 3-4ft worth of extensions and a swivel to get the 2 top bellhousing bolts out. You also have to loosen the motor mounts and lift the engine at the front hook slightly, which will help out a lot.

IDEA*** You can possibly use a jack and a block of wood to slightly jack up the front of the engine instead of using an engine lift. Just be careful where you place the jack and this may not even be a good idea**

W58 is from a 95 Sc300, it is a push clutch. I would suggest a full face slippable disc if you don't plan to drag race.

This disc really grabs and is actually almost too much grip and no slip.

I'm using the R154 setup in another car.
