We should start a supra guitar fans group. FWIW I have a bunch of guitars - including an 11.5 lb 1994 LP standard. The last time I played a full gig with that, I had backache for a week!

Hi All, I have an A02B small case differential. This is the torsen II LSD with the 200 mm ring gear and 3.71 final drive ratio from a late-model auto TT. The differential is in great condition, but I'd like to lower my gearing to n/a spec, so does anyone have an A01B torsen differential that they would like to swap it for? Patrick

"T.T. flexplate with the welded side facing away from engine." - This needs to be stickied on the front page!! (guess how I know...)

OK, so I need the auto one. If anyone has converted from auto to manual, then you may have one just sitting in your shed somewhere.

Hi all, I need a gearbox mount crossmember from a Supra mk4 It's the top one in the attached image. I already have the straight one, but it won't work with the tiptronic gearbox I am putting in the car Cheers

The neutral start switch on the soarer box is part number 84540-50010 It's also used on the following UK models: 12/1989-09/1994 LEXUS LS400 UCF10 08/1988-07/1997 TOYOTA HILUX RN1**,YN85,90,1**,LN85,90,1**,VZN130,KZN130 Neutral start switch on the tipTronic box is part number 84540-30320 It's also used on the following UK models: 01/1999-06/2005 LEXUS IS200/300 GXE10,JCE10 08/1997-12/2004 LEXUS GS300/430 JZS160,UZS161 01/2005-11/2011 LEXUS GS30, TOYOTA 35, 43, 460 GRS19*,URS190,UZS190 11/1995-07/2002 TOYOTA 4RUNNER RZN18*,VZN18* I feel a trip to the nearest breakers yard is coming on...

I just checked, and the ABS sensors are 2 wire, so they are using variable reluctance - the same as the 2 wire sensor on the gearbox. That means they'll be generating a sine wave, not a square wave, and you won't be able to use one to drive the speedometer without some intervening signal processing.

You would still need to modify the signal from a sine wave to a square wave - but that can be done with a single chip: https://uk.rs-online.com/web/p/schmitt-trigger-inverters/3332899/

It may not be worth building one at this price : https://www.jaycar.co.uk/corrector-speedo-module/p/AA0376 according to this Aussie site, this should work. However it posts from Australia, so the customs charges will go on top.

It looks like I may have spoken too soon about being able to drive my speedometer from the EcuMaster, it doesn't support routing that signal to 1 of the custom output channels. So I'm now left with an interesting problem: the 2 wire speed sensor on the tiptonic box works using Variable Reluctance. That means it's output will be a sine wave which increases both in frequency and voltage as the speed goes up - basically, it generates a small AC current. The signal that the speedometer is expecting is a 5 V square wave with 4 pulses per revolution. This is the same problem that Rossi Dave has - and the simple solution is that I need to buy a Dakota universal speedometer signal interface to convert the AC from the 2 wire VR sensor to the 5 V square with the speedometer needs. The alternative is to do some homebrewed electronics to convert the AC into a square wave, and then put together a signal divider to get it to the right frequency. Oh what fun...

Thanks Mike - that should sort things out

Does anyone know part number for the neutral park switch connector for the soarer A340 box? It's not the same as the one in the Supra. Here is the Soarer one: https://www.dropbox.com/s/7e3bi80tkt06khs/20190212_163556.jpg?dl=0

Hi All, I'm trying to convert a manual transmission Soarer back to automatic gearbox (don't ask why). The engine loom I have does not have the plugs to connect to the automatic gearbox. If there's anyone who has already converted from auto to manual - do you still have the plugs that connect to the auto gearbox? Most people snip them off and throw them away. If you still have them, please let me know. Patrick

Unfortunately, the lack of the 2nd speed sensor is an issue if you are not using a stand-alone which supports modifying the speedometer input/output signals. If so, you are going to need to either spend some money another device or find a way to divide the existing 12 pulse signal from the gearbox into a format which the speedometer will understand (Sorry Dave!). There are a couple of DIY projects on Youtube which show how to do this (here is one: ), but they do require a certain amount of electronics skills. I should be putting this box into the car within the next few weeks, so I will update on progress.
