also i would like to know if i would need to upgrade anything on the bottom end

 

well hope this helps because i went through a long process in my f22b1 swap into a 90 accord ex and no you can't use the injectors off them because will idle funny and give problem the 94-97 injectors are longer than the ones in the 90-93 and the throttle bodies are also different so sorry for bustin bubble no will have to find ones off 94 -97

 

he is correct.....the only possible way to no have a wierd idle using the 90-93 injectors would be to swap in a 90-93 intake manifold and then you run into vtec problems as well as fuel pressure issues ...save yourself a weeks worth of headaches and just get the injectors that are meant for it...as for the throttle body....that wont swap well either...the 90-93 is just the throttle body while the 94-97 has one of the valves on it....hope this helps
