First off, am I correct in assuming that the 1989 Ram 50 is ONLY equipped with a KM148 Auto Trans? If so, what other 4 cyl motors can I mount to it? Will the Ram 50 1990–1993 2.4 L 4G64 I4, 116 hp, fit in my '89, with the KM148? What about the 'DOHC turbocharged intercooled version' of the 4G63, offered in the Galant? What about the 'turbocharged 2.0 L 16-valve DOHC 4G63T' offered in the early '90's Eclispes? What about Mazda B2200 or B2600 motor/tranny combinations?

Again, thanks for all the help. I a little weary about putting a V-6 in there, but if everything was to match up okay (with my existing KM148)...I guess it would be okay. Really didn't think this would be so hard to do
