Does anyone have a crossmember made for the rx7 fd to go into the b2200 or tell me how to swap the tail housing from the b2200 tranny to the rx7 fd tranny? Any advice will help thanks guys

The B2200 tranny is an M series while the FD tranny is an R series. There is no interchangability of the tailhousings.

Fabbing a new crossmember shouldnt be a difficult matter. If you were close to me, I could do it in an afternoon, but if not, any competent welder should be able to make something work. Theres not a lot of stress on the trans mount/crossmember.

Ok well I live in haw river north Carolina I have a question and buddy of mine who is really smart when it comes to any kind of motor or anything drag racing related but not on the rotates and neither am I he seems to think that if I do not make a rubber mount for the tranny crossmember that it with crack the tranny seeing how it has rubber mounts for the engine and in the rx7 fd car the tranny member is just a bar that bolts from the tranny to the rear end with no rubber mounts can u tell me if that is true or what I should do about rubber mount and just mounting it straight to a crossmember? Any advice is really apprictated I have been stuck on this for two weeks thanks

Actually rotaries run very smoothly, and get smoother as the rpm's increase. So rubber mounts arent especially important, and I have run solid motor mounts as well as trans mounts on a streetcar with no issues.

A cammed v8, on the other hand would rattle the car apart...

I forgot to ask about the upper tranny mount do I need to make a mount for it as well or what that's a whole nother issue

I got the crossmember figured out and made now I need to know what mods can I do to this stock fd motor to get more power I have a 3' Megan pipe for it and with it being in the b2200 I have to have a intercooler that is 31.5x12x7 is that going to be too big? Any info would help I just don't want to waste a bunch of money I plan to let this motor give out b4 I do I master rebuild with bigger turbo and polished cases and other things. Thanks
