You could use your B16 crank, but I think you would drop compression and I know you would still onlye have a 1.6l.
Use the LS crank. PR3 pistons will work (but I don't know if they will work with eagle rods).
I have an extra oil line around (I am not sure if I have all the pieces for the T, but those are easily found at a hardware store) as well as some LS rods with JDM B16 pistons (I think PR3) that yeild about 11.3:1 with a B16 head. Let me know if you are interested in any of these.
