8.5” m90 disc is hard to find, most options are 9”. 8.5” is ideal for a t5 swapp I think
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
I've had a late model W58 behind my whiteblock for a number of years now. I like the ratios, how quiet it is, and it shifts ok. Since it fits in the car and works I'm happy with it but I probably wouldn't go through the work of fitting another one.
The availability of 1UZ to W58 adapter plates makes it seem like an attractive bolt in-ish option but the remainder of the integration was death by a thousand cuts. Getting the shifter to line up in a 240 is a pretty involved cut and weld process since no suitable off the shelf relocation kits exist. I definitely engaged in some self flagellation with the clutch and clutch release situation and I wouldn't wish that experience upon anyone.
If I had to do another manual behind a whiteblock I think an AR5 is the most attractive option to me.
I'm going AR5 (solstice/sky transmission). $450 for a low mileage take out from LKQ. R154/UZ adapter plate from Xcessive and a 960 bellhousing bolts it all together. Pilot bearing for a vanagon. Uses an LS1 style slave out of the box and just needed a 1/2" space for it all to work. The most expensive part is actually the shifter from Drift Motion for it to line up into the 240 shifter hole.
AR5 is essentially a super late model R154 and has been shown to be good for 700-800 ft-lbs.
M90 is a pain in the ass to get to the US along with any of the welded together BMW boxes.
That all sounds very promising! Thanks for posting.
So the trans can accept the r154 adapter, and the 960 bell housing bolts in because of the aw30 sharing the same architecture as the Supra box? Very cool.
Happen to have a link on the shifter kit? I see a few different options on their site, but they're all cheaper than the adapter plate.
That T56 adapter would be largely the same as doing the R154/AR5. If I blow up the AR5, I know what I am going to.There's a couple of approaches to getting a T56 bolted up that I thought "hmm, that looks promising" and then threw in my engine swap research folder, to likely never personally revisit.
From Sweden, adapter from the whiteblock to a GM (or BMW) bell: https://shop.klracing.se/sv/artikla...r/adapter-plattor/volvo-vit-motor-/index.html
From Australia, adapter from the Aisin/Volvo auto bell to a T56: https://www.rodshop.com.au/bellhous...2uz-3uz-adaptor-plate-tremec-t56-6-speed.html
Would still need to set up a clutch, but that's in the territory of "find an old-school parts guy that can find a pilot bearing by size, use 850R flywheel, have someone like Spec Clutch make a hybrid clutch disc, buy and set up a universal hydraulic clutch according to its directions."

Yes if you drive it like a granny.Stating the super obvious here, but you could put a Volvo M46 behind a 600hp engine and drive it around and not break it with obvious caveats.

A friend of mine with extensive Toyota experience went to test drive a Caldina wagon with a twin turbo 1UZFE setup in it, and a W box - the owner was driving it, and refused to floor it except in 4th - instant death to which ever gear set you were in. Look at the images of the R154 and W58 side by side, it's like a pencil finger nerd next to a body builder.
I have a friend in Atlanta with a ~400hp turbo 2.0 in a Miata with stock Miata trans and because he doesn't dump the clutch and hard shift it all the time, it lasts. I've driven it half way to Tampa bay and back, and it's as quick as you'd expect but always on borrowed time, limped along by a careful driver/owner who doesn't abuse it - those transmissions are not even as strong as the W58.
My ~400hp Mazda B2000 has the same trans as a turbo RX7 which is a decent box, and I've put some abuse through it, and not broken it, however if you talk to RX7 guys making bigger power than me, with stickier rubber than me, they break them, too.
Interesting to learn about the AR5/MA5/AX15/R154 family similarities - I wasn't aware of that, though I had never researched it either. Good to know, cheers. Makes perfect sense for the white block really, given those adaptors and how easy it is to make one yourself anyway. I will keep this in mind if I decide to manualise my 960 wagon in future.
I think the alignment of trans adaptors being critical goes without saying.
The crucial step was setting up the run out. I think if you try to run one of these with a cheap bell-housing or adapter without verifying runout, no transmission will last very long. I had a machine shop dial in the run out to less than 1 thou. I believe most stock automotive manufacturers shoot for less than 4 thou. I bought a bellhousing and flywheel and disk from Dellow Automotive in Australia. It was clear that the bell housing bolt holes had been drilled using a template and the input shaft runout was more than ten thou. I knew there was a problem when the bronze spigot bush exploded......thats when I took it to the machine shop, had them redrill the locator dowels and had them build a centered holder for a 10mm spigot bearing that was a press fit into the rear of the Jaguar crank.

"Build your car to achieve your goals." Solid advice.
Thanks for posting. When you say verify runout, do you mean for the flywheel, or internal trans parts? This will be the first time I set up a manual transmission
