From what ive got you need everything from the front tranny mount to the driveshaft cause the manuals are longer. Also the clutch assembly, master and slave cylenders, i think that covers most of it.

(Taken from supra forums)
I just completed my 5 speed swap 2 weeks ago. If you have a complete 5 speed parts car you will have everything you need to perform the swap. Here's what you will need:

5 speed.
Flywheel and bolts off of the 5 speed car
lower "wing" tranny mounts that bolt to engine (they are different)
Inspection cover between tranny and engine
Driveshaft from 5speed
Pedal Assemblies
Master Cylinder

The whole swap is really easy. I've never tackled anything like this before and did it in 3 days. I could have done it faster but I was waiting on my clutch assembly so... The only custom work you will have to do is in the tranny tunnel. You MIGHT have to open up the hole for the shifter tower. I opened mine up a little and found out later that I didnt have to. I think it depends on the year model. All the holes are drilled for you to install the pedal assemblies and the master cylinder. One thing I would also recommend is that you have a braided stainless hose made to run from the master to the slave cylinder. The hard line is really hard to get out of the car because it runs underneath other hard brake lines and you wont be able to get it out. You could buy all 3 pieces from Toyota for about $65 or make a new braided stainless hose for about $35.

On to the Wiring:

As for bypassing the neutral safety switch... haha... I feel bad for the many people who have paid someone to bypass this..... I can give you a REALLY easy tip around this.... There's three harness connectors on the Auto... look for the one that is round and has three wires running in it, a BLACK wire, a WHITE wire, and a BLUE wire.... Cut that plug off the tranny with some wire to spare.... Take the WHITE and the BLACK wire and splice them together... Plug that connector into the harness side in the car.... Your ECT ECU will now think your car is in park all the time and it will start right up. Too easy.

You can then wire the clutch switch in line to the ignition wire that runs to the starter relay. It's a white wire coming off the ignition switch. You will only need to do this if you want to have a clutch safety switch, as it isn't necessary. Too easy there too.

The reverse lights I haven't gotten around to hooking up yet.... I will tell you that the harnesses are different between the auto and manual, but the wire colors (RED WIRE & YELLOW WIRE) are the same. therefore, get the male end of the harness off of the donor car and then splice into the male end of your car and you'll be in business. One of the 3 round plugs on the car side have the red and yellow wires to splice into. The manual reverse light harness is a TWO plug harness with a RED wire and a YELLOW wire.

The last one that you need to be concerned over is the Speed Sensor. It's a Rectangular plugged harness with 4 or 6 wires I forget. Anyways, they are identical between the manual and auto, so the manual harness will plug right in. This will enable your cruise control to work. The other wire you have to worry about for cruise to enable is the switch on the top of the clutch pedal itself. It opens the cruise circuit and disables cruise when you press the clutch in... I never hooked mine up because I have an aftermarket wheel and pulled my cruise module out. I will investigate further and get you an answer on that too.

That's really about it. Everything aside from the possible cutting is a bolt on afair....

Oh yeah, one thing I had to do... The hole in the back of the crank for the pilot bearing seemed to be a little to small for the pilot bearing to go all the way in... I used my dremel and sanded it open a tad bit to make a snug fit. That pilot bearing should be fully seated into the back of the crank if it's installed properly. You'll see what I mean when you get up in there.

That should be about it.... PM me if you have any questions or if I missed anything. You'll honestly be suprised at how easy it is.

Good Luck

Hope this helps man, and like he said, good luck.

I'm just curious... if you're going to swap to a manual, why swap the W58? Why not the R154? Are you ever planning on going turbo?

[suprabran]

Look in junk yards and find a whole parts car thats manual. My friend swapped out a auto to manual for his civic and the parts ran close to $1200 thats with a upgraded clutch, and fly wheel. He found a wrecked one with a pretty much new clutch in it and was 500 for the whole car so he saved a lot. If you want you can try this. If you do get a whole parts car hit me up and I will buy a speedo cable from you, make some money on the other parts.

[Fubar231]

will, maybe he isn't trying to track his car up, maybe its going to be a DD? lol, either way id still put the R154 in it if i was him, just to be able to handle the power

[willtotheumm]

Very true. I'd also just swap in the R154 just for, someday, if he wanted to build it, he wouldnt be swapping a 3rd tranny in (lol it'd be cool to say that that car has had all 3 optional trannys)

Good luck with your swap dude! Keep us posted

[89supra884]

i would deffiently would want to go turbo one of these dyas in the near future, and i know i would have to do a r154, but i already have the w58 tranny, clutch master cylinder and clutch slave cylinder in my grage, soon to have a flywheel.

i dont know if i should sell those, because i ony bought the w58 for 100 bucks.


i dont know, but it would proboly be a while before i turboed it. works sucks and is slow as hell.

[Fubar231]

You could probably find a R154 tranny by its self for descently cheap. Everything else is interchangeable if im correct...

[willtotheumm]

Ah see I didnt know you already had the W58. My bad =)

Well if you dont think you'll be able to turbo it anytime soon, i'd swap in the W58 too. Any manual is better than an automatic =)
