this proto type is built from the instructions guys buy from austrailia on E bay, its supposed to adapt the T 56 to the 2jz bellhousing.

Hey Bill do you think the t56 will be able to shift smooth at the high rpm's the 2jz will rev? My rev limit is set at 7,200

 

 

if your gonna drag race use the auto trans set up I built, otherwise the T 56 will do anything you like with the Jz engine

I see you have it mocked up on an LT-1, Do you have plans to make one for the LS1 too? It would make the TOB conversion on the Toyota bell a lot easier.

 

very nice job man.

the guy came to my place with plans he bought off E bay, so I built a couple for him, I used the early short shaft just because I had it, I am not a big fan of adapters on bellhousings, but thats what he wanted

The LS1 ( I believe) is the longer shaft T 56 ( its 1.3 inch longer then the short shaft) to my understanding, the guy was building it for the LS1 long shaft, I know he intended to use a 3 disc clutch system

 

A couple of observations about the plans, I had to change a lot of details to make it right, I was not impressed with the demensions nor the lay out of the drawing

yah, the LS input shaft is about 3/4" longer so making it out of billett would be expensive, but cast would be a snap. Centering/bolt holes are the same on the 2 different midplates.

because of all the different T 56 input shaft lengths, I built a depth tool to make sure of my designs

the slot in the dummy input shaft is the short shaft T56 and the full length is the long shaft T56 , I came down on the number 1.3 in difference

The LS Bell is also deeper, so the net difference LS to LT is about .75" (not measured precisely). Without the LS bell length factored in, it is indeed about a 1.3" difference. Since you aren't using the LS bell in that design, so you are right.

 

Either way, you should be able to sell those if you make both, and the LS will probalby be easier to adapt for the end user.

is it the bellhousing that is deeper? or the front transmission cover?
