Does anyone know what it's gonna take to swap in a fuel injected Toyota V-6 in place of my fuel injected 22R-E four banger? Will the stock tranny work with it? What about the computer and all the wiring? I have 1990 Toyota 4Runner 4X4 with the 22RE four cylinder with a 5-speed manual tranny. It just doesn't have the pulling power that I need. Is there any other options? I can't pull my atv over a steep bridge any faster than 40mph. On level ground it pulls just fine but I'm scared that I'm going to get run over on the bridge. Other than the pulling power, I love the truck.
