I know its a good idea to build everything, I just want someone whos either done it or has experience with if its actually needed or necessary or what power lvl they fail or etc. I wanted someone to come out and say, I would recommend this because at X power level they will end up failing. If its going to need to be built, this may get a little more messy and we'll just have to limit the power for now. I'll give syncrotech a call and see what they have to say as well on my options.

I have been reading around on here and it seems that theres an adapter block or plate needed to bolt the base transmission up to the SH block (22a4 correct?). Does anyone know where to find this or is there a company that already makes this? We unfortunately have already built the block up with GE sleeving and the whole nine yards ($400-500+ in machine work on top of the sleeving to get the bearings/crank/etc all perfect in spec) so we can't undo this as it would costs thousands more and put us months behind as we get into winter (everyone slows down).

Thanks for the information and thanks in advance for the help!
There is not a company that makes the adapter plate to bolt up a non-SH transmission to the SH Block. However, if you search on this thread, there is a diagram and even a CAD File you can download that you could give to the right shop and they'd make it for you. There is also detailed instructions on how and what you need to do. Just search for "adapter plate" or something like that.

I'm in your same boat. However, I'm not really putting any more money into my car, so I never got to do this modification. I too, am running a fully built SH block (by Golden Eagle) with the ATTS Transmission still on the block, but it's disabled due to me now running Hondata.

I don't know if this matters or not, but I have seen proof that even with the ATTS still on, I'm laying down roughly two even strips of rubber when i do a first gear launch. I did it in a Wal-Mart parking lot at night semi-accidently and I stopped the car and got out to see if I was spinning only one wheel. This is the only time that's happened to me and I got out to see the net results, so take it for what it's worth but it almost seems like even with ATTS disabled, it still has some benefits of being an LSD in a straight line.

Good luck on getting your block adapter plate, make me one for free while you're at it, haha.
