The V8 Soarer one may work with an adapter for the tacho (depending if the signals are the same), but then the speedo might work differently, might work off an electrical signal.
The actual dash size in the Soarer I think it would be larger than the Supra, which may pose a problem with the fixed binnacle of the Supra.
Add to that the huge wiring hassle of getting all the gauges working, and then they may not be calibrated for the different operating ranges. Might be better to just get an adapter to try and convert the signal for the factory tacho.

The tacho readout would be right if you used a Soarer instrument cluster (you'd need one of those black boxes that Grant sells to make sure it delivers the correct voltage).
MA61 is a cable driven speedo. Soarer one would be electronic I'd imagine. That said, the electronic speed signal generator may possibly swap on to the box where the speedo goes so you may be in luck (from a late model W58 - Norbie will know).
The other thing might be to investigate the UZS131 Crown V8 cluster (this may possibly be a cable drive unit). It looks similar to the MA61 dash, probably a better match for size and I'd imagine these would be cheap as there is little calling for these dashes in Australia.

yeah the crown dash is more what im looking for...I just hate big tachos and gauges hanging off my dash thats all!!! Does the crown have an oil pressure gauge on it? yeah how much at a guess would i be looking at for one of these dashes and the parts req'd for the job done properly?

Blake, I suspect you'll be a little on your own here. Putting the dash in would fairly straight forward (make mounts to hold it etc and make it look neat and tidy - if you were a patient finicky guy, you could make it look good), but the wiring may be a little more of an issue. Norbie has some contacts, and he's in your part of the world!
I can't remember if there is an oil pressure guage or just a light on the Crown dash.

OK here's what you'll need to make a late-model dash work in your MA61.
Speedo: you need an electronic signal from the gearbox output shaft. GT is correct, you can use a sensor from a late-model W58 which is interchangeable with the speedo cable drive. I recently did the reverse with my W58, ie replaced the sensor with a cable.
Tacho: this works off a digital signal from the ECU, so if you're using a conventional single-coil ignition setup you'll have to find a way to convert the coil output into a suitable digital signal. Grant from SixWorks may be able to help you here; he sold me a "magic box" which made the MA61 tacho work with the 2JZ's electronic output, so he probably has another magic box which does the opposite.
Temp gauge: you'll need to wire this up to a Toyota temp sensor which must be located somewhere near the thermostat. You can use a sensor from practically any Toyota; they all have the same output voltage range.
Fuel gauge: you should be right with this one; to my knowledge all Toyota fuel level sensors work the same, so just wire it up and hope for the best.
For any other gauges which may exist on your instrument cluster (eg oil pressure), you will need a corresponding sensor hooked up to your engine. Warning lights and indicator lamps etc should be a no-brainer provided you have a wiring diagram for the car and the instrument cluster.

ahhh NUTS...
i was hoping that the 7m being a single coil would get around everyone elses tacho probs with the 7mgte in the ma61, but if its the 5me ecu that does the tach signal, im still fucked 
any thoughts on this one?

we're both in a similar boat my old friend 
Ill work out pricing this week and hopefully if someone sells me a cluster cheap i can price some components...a supra is too nica car to have vdo gauges all over the dash

ahhhh..... oops, perhaps all is not lost then
so, anyone - can you confirm that the MA61 tach is a stand alone unit, and uses a raw single coil signal directly? ie without interference or procesing by the 5me ecu?
cheers

Yes, the Supra dash takes a signal directly from the negative terminal of the ignition coil. You should have no problems with your 7M-GE. 
I was planning to use the Aristo dash in my Supra but that's been put on the back-burner for a while. For the time being I'm using the original Supra dash, which is now functioning correctly with the new engine.

As Norbie says, it should be straight forward for you Ed,
BUT that's what I thought for mine as I was comming off the equivalent, negative side of the coil output of the Microtech(which internally adds the 3 negative coil wires together internally on the 7MGTE Microtech) and it didn't work so its got me! It's the same format of signal.
Let me know how any of you guys go with your tacho hook up, i'm very very interested.

I was under the impression the 7MGTE requires MSD tach adapter part# 8920 and hey presto bobs ur uncle.
........actually he is.

so what was the verdict? Is the crown's speedo sensor or cable driven...Gt - you werent sure??? Norbie ill perhaps buy your sensor if its for sale???...depending on what the outcome is and if i buy the v8 dash

A late-model Crown will almost certainly have an electronic speedo. From what I can gather Toyota abandoned mechanical speedos around the late 80's.

bugger...so the crown is the better fit into the ma61 than the soarer? I spose if they're both electronic speedo it comes down to personal preference...anybody got some pics of either a crown or soarer cluster? Ed if i buy this dash of the fastj ill buy your sensor. Or ill start searching for another one..i would like to know if either of them had an oil pressure gauge tho
