The LS tranny will be fine.
The only times that i can think of to run extra wires is when you:
a) go from OBD1 to OBD, or reverse
B) add Vtec
YOu will need a LS or skunk2 intake manifold, also the integra throttle cable will be needed. but wiring should be just a plug and play. But if anyone know anything, please correct me.
