If I wanted to do this I would need the hubs, sleeves, synchros from the b16. Will I be able to use my LS mainshaft? Would I need the shift fork from the b16 for it also?
To run the b16 FD I would need the countershaft from the b16 and ring gear correct?

 

You'll need the gears themselves (main and counter shaft gears), hub, slider, synchros, synchro springs, and shift fork.

You will keep your LS mainshaft.

You will need the B16 ring gear and countershaft if you want the B16 4.40 FD.

 

Thanks. I wasn't 100% sure so I had to ask.
