u need integra spindel and hubs for ur motor swap and yes u will need to convert dpfi to mpfi if u dont really wanna mess around with the wires u can just buy the conversion harness on ebay for $129 and from there it will be just plug and play, but u will need a resistor box for the injectors.

u will also need ef-b-series motor mounts u can buy those also from ebay like hasport or innoative motor mounts make sure u get the cable trans mount if u planing to keep it cable.
u need ls axles, manual intermediate shaft, umm thats all i can think of right now.

Si calipers are different from the std, and pretty sure the rotors are too

I think the std has the same brakes as the dx and si, the EX has 10.3" brakes. If you want that brake setup, check out my fs thread in my sig.

wtf are you talking about. The LX sedan NEVER came multipoint. Just use your stock harness and convert to mpfi. It is A LOT easier and less time consuming than swapping harnesses. Plus you would need one from a hatchback SI, not a sedan since the wiring is different. Also just because you have spark, fuel, and compression does not mean a motor will run. Those are the bare basic essentials, but a lot more is involved. Start your own thread instead of hijacking the op's thread.

dx and si knuckles are the same... at least the part numbers on the two sets of dx knuckles from two dx cars (a hatch and a crx) were the same as si part numbers

That's because they are the same. Only EX knuckles are different from the larger brakes. STD has the same brakes, but a different axle input.
