they do rebuilt motors but they alrdy have the long blocks in store so you basically send them you motor and they send u a crate motor back....not the one you sent them but one that is rebuilt to factory specs they also assemble transmissions though im not sure if they will rebuild your transmission...you might want to call them up for that, my friend used these guys to get another h22 but just the block, also

try these guys..i just found them..they remanufacture and rebuild supra motors also...plus u get a 7yr warranty which should make it pretty reliable
as for the transmission:

www.jdmenginedepot.com they update their site weekly if not daily..with their inventory...but they dont list everything they have so you might want to call them up...i hope this information helps you
