hi my name is brian and i was wondering how hard it is to switch my 87 accord to efi or if it is even possible with out switching engines???

 

it prob. can be done and a crazy cost. Not worth it. B series civic and teggy engines are swappable in your gen accord tho

 

True, maybe easier to swap to the motor with one already set up, of course there are the "other" things needed after doing this (wires harness, ECU, EGR stuff, ect). But to answer the question, Yes it can be done. A webber conversion might be another option....what are you trying to get/solve by this?

 

so i can put a cold air intake on it and and more performance wat years have the b series

 

ESP makes mount kits for D series B series engines that can be swapped in your gen accord.
If you want power your better off doing a swap. The cash to power ratio will suck if you try and build your stock engine.
