swap

[blue86supra]

im wondering whatou all need to do a automatic to manual swap i have a 1986 toyota supra n/a and want o sswap both my engine and tranny into an 87 supra is there anything special i need to do the swap or is everything i have good to go

[Jeeves]

Is the 1986 car an 86.5? Or from a Mk2 supra? A swap should be near straight across (if it's in a Mk3 -> Mk3), but you never really know till you're in it.

As for the auto->manual, there's a decent amount involved.

yes it is an 86.5 and im swapping out the the auto to put in a manual...so im not going to need anything special for the job since both of the cars are the exact same im just swap everhing from the manual into the other car..

If you have a manual parts car you should have everything you need. If you have only the transmission, you need a lot of little pieces...

[iwannadie]

what about the drive shaft, can the one in the auto car be used with the manual trans?

or is it just little stuff needed like linkage and pedal and all that?

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

Then there's the wiring...

Since it seems like I'm the only one that's done it, don't get me wrong - others have, I know - just NO ONE during my search was able to provide exact details.

Ok, well... here goes nothin'.... my attempt at enabling the reverse lights in a "how to" thread.

I don't have a schematic book, so connections will be based from plugs and wire colors in my '87. And for ease of install... I cut the harness from the auto tranny (basically wanted to use the plugs).

In the attached pic, from left to right, you have the following:

1. 3 wire round plug, wht/blk spliced together enable the bypassing of the clutch (ie. pedal pushed in isn't required to start the car) and the blue is 1 of 2 wires needed for the reverse lights

2. 6 wire round plug, this plug actually tells the ECU which gear the car is in. If you searched for "auto cookie" you'll find some more info on what lead to the connections. Anyways, the only wire needed from this plug is the blk one (this is 2 of 2 for reverse wiring)

3. 6 wire square plug. not used for 5 spd. IIRC, it was linked to the 3 solenoids on the DS of the Auto tranny

4. 4 wire square plug, its a direct plug'n'play for car's with an ABS system.

Now... just connect the Blue wire from item #1 above and and the blk wire from item #2 to the reverse sensor plug found on the PS side of the 5spd. tranny and your done. Working reverse light!
