Outer Limits 4x4 Board

My rrc broke down (suprise suprise) last night and i have no idea what the problem is. its the old 3.5L carbie and i was thinking its going to cost me just as much to get it fixed as putting a new engine in. So this thought lead to the idea of swapping the engine. i was wondering what my options are, should i stick with the 3.5l? or upgrade to a later model engine? i am doing the swap myself so i need enything to mate up, i dont want to go changing or modifying things to fit different engines. i also want the keep the cost down due to the car only costing me 900 dollars. any help would be great! thanks

Slow down there mate, it may not be terminal. Give us some clues and maybe year ,trans etc and someone might be able to help you.
