^^ I like those transmissions. The Magnum is rated for 700ft-lbs from Tremec (although they claim it can do more) and they can be ordered in two versions with different gear ratios in each. Down the road I've thought of buying one to set aside for another car.
Wait.. did they cast their own bellhousing for the 2JZ application?

Awesome, they cast their bellhousing, Only $599 for it. Nice to know as I have a T56 sitting in the garage if I ever decide to do another 2JZ race-car would definitely go this route. The F-body driveshaft was a direct bolt in for my LS1 conversion on my SC, so I'm sure that would work as well. You can find the T56's for $1000-2000 used/rebuilt.
Faceplated gears and a rebuild for around $2000. Normal rebuild is only $800 with labor and parts..

Yes, I used the stock aluminum F-body T56 Driveshaft with a bolt-on adapter for the differential. This was with the LS1/T56, but the transmission output should be in the same location if it lines up with the shifter hole. The driveshaft has a couple inches of forward and back adjustability. Search my LS1/T56 thread and it list the parts needed and how I did it.

^^ Wasn't it Gerrb or someone else who said the rear seal leak can start as early as 500whp on R154's? I know the 600whp has been mentioned with the rear seal leak on SF. I always understood it as YMMV regardless of which R154 variant you have.
650-700whp (though I've heard 750whp and 800whp too) is supposed to be the upper threshold power limit the transmission is capable of before breaking. The issue should show before those figures, I think.
Does the JZX100 shift housing breather really make that much of a difference?

The R154 doesn't seem to survive above 700 torque as per experience of many. The stock 2jzgte / R154 which used to be on my 97 5speed when I got the car from my buddy Aaron was only at around 450rwhp at 15psi before the dyno session was stopped due to leaking rear seals. As Intimazy said, he was not even also at the 500rwhp level before getting those leaks. Dennis (Jeslet) had that AR5 running good in his SC300 but parted it out before even going stand alone and dynoed it. He now has a V160 / 2jzgte on his MKIV making 700rwhp on that engine / turbo setup that used to be on his old SC300 with the AR5.
I hope to see well tested setup for the CD009 and TR6060 mated to our 2JZs that can handle well over 800 torque .so we have good alternatives to the V160 which is very hard to find now and ridiculuosly expensive for second hands.

I talked to a local guy, he said he's making 1000hp in his turbo Mustang on the stock T56 Magnum. On the Facebook page it says they're shifting at 10k RPM and the level 5 can hold 1600hp.

The first adapter for the CD009 that used the auto flex plate, looked like a weak point to me. The flywheel still looks a bit bulky imo. I'd personally feel more comfortable with the T56 magnum, even the regular T56 holds 500-600RWHP abuse on 4,000lb LSx powered cars with a ****load of torque at 3,000RPM.

Hello, I'm finally saying hello. I'm on the my.is forums. I see the picture above with the trans on the table with the blue realco rz shifter. That's my transmission I used in my first auto to manual swap in an 01 IS. I used the internal GM slave cylinder with w58 push style clutch. I've just completed my second AR5 swap on my current factory manual 02 IS300. I used the external Toyota slave and clutch for the r154 transmission. I did this just to have the experience of doing both ways. When I prosper more I'll do one with a twin disk. @ what power levels are know to make the r154 leak? My first car was n/a but I'm currently GTE non vvti with gt35r. My factory w55 broke 4 whole teeth of the input shaft. So I don't know my HP but I might have enough to test the leaky theory?
So I have a 1jz non-vvti swapped into my Mercedes 190e-16v. R154 is in need of a rebuild so I bought an AR-5. I know that the s-10 2.2 clutch disc is required to make the swap work. But if I purchase a w58 pressure plate and flywheel does the AR5 internal slave work correctly? Or are there other modifications needed? (Shimming, etc)

Mark (OP) himself was around 521rwhp ... one of his perennial problem before he sold his setup was rear seal leaks . Got two other local friends .. same thing that is why they abandoned the R154 . Well I guess it really all depends on the transmission's condition and how the car is used. Richard (8052jz) I believe had his leaking also on the shifter area. But he is on a TH400 now.
The R154 doesn't seem to survive above 700 torque as per experience of many. The stock 2jzgte / R154 which used to be on my 97 5speed when I got the car from my buddy Aaron was only at around 450rwhp at 15psi before the dyno session was stopped due to leaking rear seals. As Intimazy said, he was not even also at the 500rwhp level before getting those leaks. Dennis (Jeslet) had that AR5 running good in his SC300 but parted it out before even going stand alone and dynoed it. He now has a V160 / 2jzgte on his MKIV making 700rwhp on that engine / turbo setup that used to be on his old SC300 with the AR5.

I'm interested to see the results of a TR6060 or T56 Magnum (same thing but the aftermarket version) used against our JZ engines. The CD009 also. The AR5 at this point just seems like a good alternative for the 5-speed R154 if it suits someone's needs and power level goals. I'm happy with my R154 being overbuilt for what I will use it for but if I were going as far as you, Gerry, I'd definitely look into another stronger and more modern gearbox.
Here's hoping that I won't be able to report rear seal leak issues at 350whp-400whp.

From all I know the V160 is still a stronger design. Still, the Magnum gearboxes are supposed to be the same as the gearbox used in all Vipers. Since Hennessey works those things over and their manuals don't blow up that has to say something.
Here's and interesting comparison of some of the best "tough" manual gearboxes you'd find on the popular muscle cars of the 60's and 70's when big blocks were the only game in town. I used to think those ancient designs were superior to 90% of modern designs because of the sheer torque of the huge V8's they were designed for but after reading a few threads and watching this video my mind has been changed. The vintage gearboxes are really just for period applications and restorations now. The T-56 Magnum really does trump basically all of them.
This is what makes a comparison to the V160/161 interesting.
I still love my "period correct" built R154 and I'm very happy with it, quirks and all. However I'm not expecting to push it to such high limits as this. Also note that this is only the TKO 600 6-speed manual. The TKO 700 is rated for more torque.
I'm actually very interested in a Tremec TKO 700 6-speed for a future (and second for me) classic Mustang application. Not in the cards at the moment but give it time. The SC isn't going anywhere though

Not unless there is a misprint or typo ... damn V160 was only rated by the manufacturer at around 375 ft./lbs (torque) while the T-56 / TR6060 is rated at 700 ft./lbs (torque) . I don't know if Toyota intentionally lowered the rating for what the V160 can handle. We all know that it had been surviving +1000 ft./lbs 1500rwhp levels. I have heard about TR6060 being used way above the 700ft/lbs it had been rated. I am not sure if that is stock though or built. The V160 had been surviving abuse at stock configuration.
Hahaha...on a side note, talking about Benz .. lately I had a crazy idea that once my MB E320 konks out ( I don't know when since it only has 100k miles ), it is getting a 2jzgte / auto trans sleeper power plant. And there is one right now posted in some forums with that setup..lol.

So I was doing some quick reading on the T56 trans and it looks like it has a slip yoke driveshaft setup with a rear seal also, but not seeing anyone say they have issues with it leaking other than people who used the wrong seal or something weird happened, so hopefully its not an issue but will look more into it.

To note also, the commonly available Tremec T-56 transmissions are not built to the same durable standard as the TR6060 and Magnum versions. I don't know where the regular T-56 from earlier model years stand in the torque holding hierarchy but it isn't all the way up to a 600 or 700 ft-lb rating from Tremec.
Gerry, that's interesting about the V160's rating. Toyota, Getrag or both undoubtedly downplayed its figure.

Joel Grannas who is a die hard V160 / 6 speed guy now uses the T56 because of hard to find parts and expensive V160s. He just did 1741rwhp on his 2JZ / /T56 setup . A new T56 , then built will be over $5k but still lower than the V160 plus all you conversion parts .
