engine change/engine wanted

I've got a 93 wwrangler 2.5L , how hard is to put in 6 cylinder,do you have to put in different motor mounts,new computer,would it bolt up to the 5 speed tranny from the 2.5L I'd rather just put in used 2.5., anybody out there have a good four cyl. the wan't to sell? I can find lots of 1980's four bangers carbuerated for sale but I'm not sure if they would work in a 1993 f.i. any and all replys would be appreciated! thanks-2gooses

loook if u want to swap the motor its gona cost you alot ur gonna need to have access to a welder to fabricate new motor mounts or just weld the ones off of the 6 different sized engine needs new mounts youll need to pull the computer and the transmission transfer case and drive shafts for a 6 cyl wrangler bcuz of a difference in size of parts all the wiring and components will need to be pullled along with the whole 4cyl driveline and you will need a larger raditator as well

if you want to swap engines find a complete donor wrangler at a junkyard and work from there if u cannot fabricate on ur own find someone to help and rememebr this anything is possible with enuff money, time, and tools
also u can make anything work if u work on it long enuff but look into engine swaps b4 u do one urself the best words of adbvice i can give is research research until u have a clear plan and then do it
