B16 mounts

Might Sound like a newbie but fairly new to b-series. will hasport mounts i currently have on b16 work with LS ? gonna pull b16 and put LS in. reason being is tranny is shot and gonna switch over wiring harness (all rigged) from rex into hatch and do some soldering. also Can i use Pm6 for now? What Ecu would be best to use? Just wanna make sure
thnx

Mounts will work, my brain hurts too much to extract the answer to the rest of it.

Dont think so Hard!!! :p
Will b16 axles and intermediate shaft work?

ok I'm Confused... your gonna swap out a B16 for the less powerfull B18 because your transmission is messed up... alright... you DO know that the B18 transmission Will Bolt up to the B16 ? and all the axles and stuff are the same... ?

If you were gonna do a LS-Vtec I would understand... but this just does not make much sense.

My white hatch is actaully my bro's because he bought it off me. im not doing it because the tranny is messed up (thats just another reason). im going to pull Ls out of rex and drop it into hatch for my bro. i am going to keep B16 on a stand for a while and build it up ( as much as money allows). Then it will go into MY red hatch to replace Current ZC. I do know that B18 tranny would work with b16 but as for axles, that was my question. wasnt sure about that 1. thnx for reply

sorry for not explaining my plans a little better
gonna start pullin Ls tomorrow
