Yeah, post some pictures!
I guess it's been pretty well covered, but I can't say I'd recommend keeping the ATTS. It's essentially an open differential with the capability to spin one tire at about 15% more torque than the other in the corners, through a pretty intense looking gearset. Having seen a couple ATTS problems at the dealership I work at, I can vouch for the fact that it is one of the most devilishly complicated things that Honda has ever designed for a street car. The gearing unit is relatively straightforward, but the electrical portion of it is scary. It will not per say give you an advantage in straight line performance, it is primarily a handling feature.
I didn't know that the H2B kit worked with the SH block, but it would make sense that Civic guys (like me) would go that route, as the ATTS gearbox will not fit into a Civic w/H22 with out some serious jackhammer work. It's one of those things that's really cool, but not what you would want in a performance car, especially because it wouldn't work w/ any engine management (unless you want to tune a piggyback to 600hp
).
Post pictures soon, your build sounds really cool!
