Hi friends. I recently bought Nissan B12 86 Model , it has GA13DS Carburetor engine... i was thinking to swap efi engine but the engine prices are very high in my country.. So please suggest can convert ga13ds to efi , because i have seen a similar engine like mine but that was efi. The shop keeper is asking 120$ for manifold,injectors,distributor,throttle body ...should i buy these things?? or i need something else.. waiting for your kind replies..
