Electronic dash/intrument cluster for conversion in MX73 Cressida

We have just done a 2JZ conversion on our MX73 and need to convert the dash and all instruments to electronic to accept the outputs from the engine/box/etc, as the old system was only analouge.
Any ideas what can go in.
Camry, soarers, celicas, other imports.
What have other people used for cressida conversions?
I would really like somehting that is known might fit, as traveling and measuring etc isnt really an option.
Cheers

You use the original speedo cable, and either get an adaptor box so you can run cable and electronic at the same time
Or just run the cable (I'm, not sure if you run the original ecu and auto)
For the tacho, get a sixworks box to convert the signal to old one.
The temp guage will wire straight up.
As will the oil light.
That is everything.

What he said. I have a 2JZ in an MA61 Supra (very similar to MX73) and I'm using the original dash. I replaced the electronic speed sensor in the gearbox with a speedo cable (direct swap) and the factory ECU doesn't seem to care about the lack of speed signal... I suspect it's only used for cruise control, ABS, traction control etc, none of which I'm using. Tacho as mentioned works fine with a Sixworks tacho booster, and temp gauge is a matter of splicing in a single wire. Too easy!

Well we are using the 2JZ ecu's but i think we really wanted to get rid of the old gauges, as they arent the most responsive or best looking.
Is it too mush hassle to change them, or just much easier to get an adapter box for the speedo etc.
Any ideas of the cost for the adapter boxes?
Cheers

Converting to a non-standard instrument cluster will be a MASSIVE headfuck. Trust me, I got about halfway down that road and gave up in disgust. Using the method I mentioned above is 1000 times easier.
My tacho booster cost around $100 from memory, but I'm not sure what the going price is these days. Shoot Grant a PM and he'll let you know.

I'm not sure of prices of the tacho booster, so I can't help you there.
But you could swap another dash in, its just a hassle to find something that fits, and even more of a hassle to wire it up.
You COULD import the digital dash from US/Canadian Cressida's, but the speedo cable is on the wrong side.

Digital Dash Pic (I have better ones at home, but this will do)

Thanks.
As for the level of headfuck, well this probably so far has been more. We just happened to get the most rare of 2J's that was from a crown majesta that had a limited run only in japan, and needed a different wiring diagram for its ecu than every other 2JZ diagram out there. It took 8 months of chasing after we figured out what it was from, and by then when we nearly had it all sorted out ourselves, then we got special permission from toyota japan for them to reprint one copy for us, then we had it translated by a friend. Lots of heartache there.
Anyway, thanks for the advice. I'll look into it.
