I need to know how to switch over my 90 DPFI to a SI MPFI setup without swapping motors I am in the process of getting an SI manifold an si ecu and the resistor box. Is there anything else i am gonna need and how do i wire it up. I plan on using my dx head still with the SI manifold bolted to it. Any info would be appreciated

 

its very easy , i can do it for a discounted price ..... im sure chahonda will chime in too
