what gear ratio are you running in the truck? what do you want to turn at 60? because to me 2k sounds about right. my 2.5 stick minivan is around 2200 and geo runs 2600 at 60Just need the v6 4wd parts and the 4cyl bell and your set to go. I'm running a turbo motor in my 95 and the gearing is all wrong. 2000 RPM at 60MPH in 5th gear. I'll be changing that hopefully this winter. I believe allmotor has done the swap and said it wasn't worth doing. I'm keeping mine 2wd.
generally you're going to find the V-8 rear axles to be the same or higher than 4cyl since a v-8 turns less rpm at hwy speed.Not sure what the ratio is as I haven't dug into the truck much after the swap but it tends to go into boost at any slight grade or tap of the throttle. The weight and aerodynamics of the truck tends to cause that I'm sure. Plus I'm running a mitsu turbo and stock NA exhaust and cat. Probably going to dig into it this winter more. I was going to look for a rear end from a V8 truck with the stock locker and a little lower gearing.
