Supra V160 Getrag Conversion
#571
2) BrockB is the only one that I know of that has the V160 going to the Puddymod diff, so he would be the person to ask for the length

Thanks for the reply. The speedohealer will only adjust the frequency of the pulse waveform, with the amplitude being your source voltage (+12V in this case). Since our ECU & cluster operates at +5V, I'd be very anxious overdriving it with a 12V input.
If/when I get this v160 conversion, I'll be sure to cap the voltage at 5V. There are many ways to do this by either using the common 2N2222 transistor driven by a +5V input for Vcc with the Speedohealer output driving the Gate. Or you can use a +5.1V high-speed zener diode to cap the 12V amplitude. There are also many TTL buffers you can buy to drive-down the 12V output to 5V.

That makes sense. Sorry, I've been driving for 12 hours straight. Another way I've thought of wiring it up, is to use the +5v from the original harness wire up to the speedohealer and still supply the vss with +12v but was going try it out as I have it wired now. The self test in the speedohealer seems to be working and displays on the cluster properly

Since the VSS in the Supra transmission is probably a dumb hall-effect or similar sensor, you could always try feeding it 5V. You may find there's nothing tricky required...

So I had about another 5 hours to think about this while I was still driving home. If the VSS is giving out a modified +12v signal, you would have to clamp the signal out to the cluster right? Which then it wouldn't make a difference where you powered the Speedohealer with either +5V or +12V. Unless the speedohealer outputs the signal with the same voltage it's powered by. But do you think it also could clamp voltage through the calibration? Postab0y said his initial calibration was around 3560%, looking at correction values on the speedohealer it seems like a lot to go that high.

It's been a month or two but I think I tried that and didn't get any trigger pulses on the speedohealer. Can't really remember though, I've slept since then. lol

I should be trying this out next week along with the trans install, I'll report back then, oh and big thanks to cd7siraccord for helping me out

FYI the Yellow Box operates at 5V.

If anyone is buying a new V160, I've compiled a parts list new from Toyota, that you will need to complete this swap.
This is the cheapest place online that I have found these parts: https://www.1sttoyotaparts.com/
Here is a diagram of the stock shifter and mount.
Shifter Assembly:
33530-14442 - 93.5-95 Shifter Assembly
33555-14100 - Upper dust boot (optional)*Will need to trim Full Blown Bracket to fit*
93381-16016 - Screws with Washers (4 are needed)
33556-14050 - Seat for shift lever ball
90387-08134 - Collar for shift lever and linkage (2 are needed)
90301-11015 - O-rings for collar (4 are needed)
90105-08200 - Bolt for linkage and shift lever (2 are needed)
90179-08095 - Nut for bolts (2 are needed)
33513-22030 - Yoke for Linkage and shift lever
33531-14010 - Dust boot (Optional) *You will have to modify this for the linkage to pass through*
90467-21010 - Retaining clamp
90250-06026 - Pin for linkage
Transmission Mount:
12371-46110 - OEM transmission mount
90179-08159 - Nut (4 are needed)
*Optional*
12371-JA800 - TRD urethane tranmission mount *Google part # for other sources to purchase ranging from $85-100*
31123-14020 - Inspection Cover *Driver's side will need to be modified for clutch lines*
31121-14030 - Inspection Cover
90080-11228 - Bolts for inspection covers (4 are needed)
08885-01306 - Toyota V160 Transmission fluid (2 cans required, need 1.8 liters transmission fluid to fill transmission)
The shift knob will not work from your S2000 as it is a 10X1.50 and Toyota is 12X1.25
Hope this helps
Cheers
