new to this forum, would like any help/advise on replacing the 22R engine in my 87 4WD pickup with a 22RE from a 86 4runner. seems possible to me, am i right? what do i need to watch out for. my plan is to take the engine/elctronics and fuel tank/pump from the 4runner (wrecked) and install it in the 87 truck, drill a hole in the firewall for ECU wires and mount the ECU under dash or kickpanel somewhere and maybe only need to splice one wire or so to the ignition wire bundle. is this doable or am i asking for headaches?
