Thanks to Pa_Jero I got some good info on this swap. Has anyone swapped a later model 3.5 SOHC in a fuel injected Gen 1? Will a Sport engine fit or do I need to stick to the standard Montero.? I'm wondering how many mods I need to make for clearance and fit, and whether the ECU and wiring is a big challenge. I want all the gauges and accessories to work in the truck. Thanks for your help.
