I've been thinking about doing a 4BT Swap in a 2003 Ford Ranger XL with a 2.3 duratec. The ranger has a Mazda M5OD-R1. I don't have any idea hiw much it would cost (I plan to do it myself with the help of a house builder, and a network engineer) if I was going to I would probably upgrade my ranger to an XLT with extended cab. And an M5OD-R1HD which is standard on the 4.0l. Any advice links manuals general dos - do nots. I would say mechanically speaking I'm a 6-6.5 / 10.
