The mounting kit necessary for installing the LS1 and T-56 6-speed transmission into the car was made by www.hinsonsupercars.com who modified the stock subframe to accept the V8 engine.
Resources for the project include Hinson Supercars as well as V8RX7 Forum, Granny's Speed Shop and The RX7club. Everything you need to know and more can be found between these sites, and without them the car wouldn't exist in the condition it does.
I couldn't have done this without the help of a few friends (hope I remember everyone who's chipped in on this thing!):
