Dunno - waiting for fundage (6 weeks away) then I will contact Geoff @ Prestige and start the search.

I'm not sure when the SEVS workshops will be ready - but have at least 6 weeks before I am financial enought to start the process.

Hmm interesting... I know you need a custom tail shaft for it, but what else remainds a mystery. When I google it shows up threads from the AU Lexus forums but they appear to be down, damn it

I think the Aristo is ground breaking stuff here in Oz and in other English speaking countries too - I specualate that all the after market resources are in Japan.

Just looking for a Turbo Kit - one would think that any 2JZ supra bolt on would fit - But after hearing from HKS through Greenline that the T04Z kit would need modification for clearances, I think this project will need a lot of custom work......

Chatting on the aus Supra forums, the auto in the 2J TT supra can handle up to 350rwkw

hI B-Man, Daniel in the supra forums had 360rwkw and ran an 11.1 with the stock auto, and street tyres (not semi slicks) with big mph so there is definately 10's with better rubber, and lately put out over 430rwkw (yet to be run with this power) on sock internals, and the box seemed to be doing alright from what i heard.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
