That gearbox also goes by the name AZ6. 

Any idea if the AZ number, relates to bolt pattern ? 

No, AZ6 is just the Aisin-Seiki name for the box (it is used in a bunch of other Japanese cars such as the MX5, 200SX, RX8 and even the 86/BRZ, but with different bellhousing patterns for all), has nothing to do with the Toyota AZ engines

Ahh Ok, thanks for the info mate. 

If that's the case, then I'm guessing you could theoretically plonk either of those engines + the box complete, straight into an is200, and vice versa. That would be an especially good swap for the rx8, as those rotary engines don't last long, and guzzle fuel. 

I guess the only way to know for sure, if the 2az-fe would fit, is to mate it upto the box, and see.

I stumbled across this video, of a guy mating a 2az-fe onto a variant of the j160/az6 box. 

He made an adaptor plate.

It looks like a good guide, for anyone that's interested in diy'ing their own plate.

Yes I've been watching his series, and chatting with him.  Hes doing it his own way, which is cool.  It is a good guide for a plate, and he just put out a video about making an adapter to sr manifold as well thats quite good.  One or two things about that gearbox choice seem a bit inelegant to me, such as the starter position going into the firewall, and the slave on top where there is no clearance, however I think he is making it race only high power turbo build so he has a diffeent set of mechaincal outcomes in mind than I.

Picked up an old neglected w58 steel case transmission at a swap meet a couple of weeks ago.  Only cost me 200 bucks but it was full of leaves and grime cause it had the shifter off.

Took it home, cleaned it up with a wire brush in preparation for a strip and clean excercise to asses its condition.  I had only bought it because it selected every gear and they felt smooth, it turned over like it was still pretty nice inside.  I found the words Dellows stamped onto each half of the cases by the steel centre plate.  It had had a conversion bellhousing from an old ford 6 cylinder on it, so it must have been sold by dellows originally.  So I came to find it was dirty inside the rear and around the shifter.  I picked out a lot of crud, like a handful of it, and then split off the rear housing.  The two rear most bearings were grimy from muck sitting against them.  It had no corrosion inside or on the shafts, the output and input shafts looked new, no end float and still with the blueing sort of finish, once cleaned up.  Compared to every box I've had before this one looked great.  So off to the gearbox shop, I ordered in the bearings, just got it back ready to use.  It owes me about 520 dollars so Im stoked to end up with a steel plate w58 for that kind of spend.  It will drop my highway rpm at 100kph from 2820 to 2580rpm with the taller 5th gear.  No other ratios vary from my current w57.  Best part is, I started looking into the speedo drive combo I need.  I know my current w57 box came from a car with a 3.58 final drive, and the 3.58 final drive cars typically use a 33-11 or 32-11 speedo drive.  The w58 I have found already has the 33-11 gears in it.  Its an older type manual speedo w58.  According to my research it might have been from an MZ11 or MZ12, an early MA61, or a late MA70.

A few cars Ive looked into:

RA65 33-11 speedo drive for 3.58:1 final drive
SX80 32-10 speedo drive for 3.9:1 final drive.
GX80 35-10 speedo drive for 4.3 final drive.
LX80 32-11 speedo drive for 3.58 final drive.
RT142 32-11 speedo drive for unknown diff ratio (borg parts not in Partsfan
MA70 early 35-10 /4.3
MA70 late 33-11/3.727
JZA80 NA 33-10 electric/4.083

JZA 70 33-10/4.1
GA70 1GFE 32-10 3.909
GA70 1GGEU 1GGTE 33-9/4.5556
GZ10 35-10/4.3
33-10/4.1
31-10/3.0
MZ11MZ12 33-11/3.7
RA63 18RGEU 33-10/4.1
GA61 32-10/3.9
35-10/4.3
33-9/4.556
34-10/4.3
TA63 TA64 TURBO 33-10/4.1
MA61 33-11 AND 31-10 BOTH SUIT 3.7
LX90 31-10/3.7
SX60 33-11/3.7
SX90 32-11/3.583 Can infer the rt142 diff ratio would be also 3.583 from this as thats what its speedo drive suits.

Just switched over to summer oil, went to HPR 10 over HPR5.  It runs fine on 5wt but its a bit warmer up here than in Brisbane so just being cautious with it.  367380ks.
