SC400 -> W58 Conversion - Work Log

[RedPhoenix]

Hello everyone. I thought I would throw up a project log of my manual conversion. Its going to be a little slow, but Jake is going to guide me in every way possible to get the ball rolling.

So here is my list of what I need for this project... ( I will update this list if anything changes )

Transmission - 1995 Supra MK4 W58
Adapter Plate - UZA70 Aluminum W58>1UZ
Flywheel - UZA70 Aluminum
Clutch Kit - UZA70 Sprung 6 puck
Throwout Bearing - Howe Racing 82870
Pedals - Supra MK3
Hydro Lines - SS Lines with speed bleeders
Shifter - Short Throw shifter
Driveshaft - Custom modded SC400 or Manual SC300
Mount - may be able to use stock or slightly modify it.

Just picked up an older model Howe Throw Out Bearing # 82870 on ebay for a decent price. The older model and the newer model will work... both are part numbers 82870.

Should be picking up the adapter plate this week from Jake.

I'm looking at tackling this project within the next couple of weeks. Where can I purchase that adaptor plate? I saw one on ebay about a week ago from some guy who makes them but I cannot seem to find it again. Good luck and please don't give up!

 

[SlidewayzSC]

Nevermind, I found it somehow. Thanks. UZA70.com for anyone else who is interested.

 

[Jake Breyck]

That was me that had the plate up on ebay. Let me know if you want one. or just go to the site thats fine too.

Matt, have you pulled the drain plug on that trans and made sure no water came out of it???

Looks like its seen a lot of sitting in wet rainy weather!!!!

 

[RedPhoenix]

It has been sitting on my balcony since August, lol. I drained the fluid out from the rear of the tranny, but have not added more. What do you recommend I do?

 

[UZZ-TT]

Great progress thus far! More pics!

 

[RedPhoenix]

Met up with Jake today and picked up my adapter plate. We also went out to get my Howe bearing serviced with a rounded bearing instead of a flat, although, it really doesn't matter. We got the lines made for my bearing too... and last but not least, ordered the clutch/pressure plate.

 

[Jake Breyck]

damn matt overkill on the copyright?

 

[RedPhoenix]

Yep, sorry, I have had many people use my pics already. This will be one that will be used lol.

 

[Jake Breyck]

sometimes that can be a good thing.

so how do you bleed the clutch slave?Do you have to drill a hole in the bell housing with an extra long bleed bolt??

n Bold = has been ordered or in my possession.

Transmission - 1995 Supra MK4 W58
Adapter Plate - UZA70 Aluminum W58>1UZ
Driveshaft - Manual SC300
Throwout Bearing - Howe Racing 82870 with Rounded Bearing option
Pedals - Supra MK3
Shifter - Short Throw shifter
Shift Knob - Vibrant CF #2032
Rubber Shifter Boot - SC300 Manual
Hydro Lines - Steel Braided Lines with a Speed Bleeder
Clutch - UZA70 Sprung 4 puck Dual Friction Clutch
Pressure Plate - UZA70 1800lbs Pressure Plate

Flywheel - UZA70 Aluminum - In Process of being made (waiting on ring gear)
Console Trim - SC300 w/o Heated Seats

so how do you bleed the clutch slave?Do you have to drill a hole in the bell housing with an extra long bleed bolt??

You will have 2 steel braided lines coming out of the bell housing.

One comes from the Master Cyl and then into the bellhousing to the Howe bearing. Then out of the Howe bearing another line out of the bellhousing with a speed bleeder on it. You can put this anywhere you want, I will hide mine under the car. Jakes is hiding in his engine bay.

 

[RedPhoenix]

Met up with Jake again to get my 4 puck Sprung Dual Friction Clutch and my 1800lbs Pressure Plate!

 

[RedPhoenix]

Here are pics of the shifter after modded. I had to get my buddy to put some delrin on a lathe and turn it down so it can cup the ball of the shifter like OEM... he also had to mod in a top plate. This sure beat buying a new shifter from Toyota for $100+ ! You guys can avoid this problem by having the OEM shifter that comes with the transmission... I did not

What style fingers are on that pressure plate?
If they are straight (like most are), the bearing on the howe unit is not suitable as its made for curved fingers.
The bearing should be a cone or slanted shape.

The howe bearing will work, but there is a good chance itll fail prematurely.

 

[Jake Breyck]

he has the rounded faced baring on the howe, aka way ahead of you, although ive been running a flat faced baring on a flat finger for over a year now.
