So here's the deal, I have a 99 Ford ranger with the V6 4.0 and a automatic transmission. It's not in the greatest of shape and I really really want the 5 speed manual. I also have a 98 Mazda B series 2500 with a 5-speed manual and the 2.5 l piece of shit with 4 cylinders and 8 spark plugs. I either want to take my 4.0 and drop it in the Mazda. Or I want to take the high-speed manual out of the Mazda and put it in my FordThe 4.0l swap to 2.5l will NOT, repeat, will NOT bolt to tranny etc, you may even need a cluster.
Basically, to make this doable, you need a doner truck. That, or a lot of impatience and cash.
Swapping a 4.0l to a 5.0l would be way more feasible, but a 2.5l to a 4.0l is nearly impossible without a whole doner truck.
