Ok hello fellow automotive enthusiast. I'm a newbie to this posting stuff so thanks in advance. I have read EXTENSIVELY for months in different forums and I don't find the specific answers, so here I go. I have a 1986 rwd 22re automatic true 6 bolt one ton full floating rear axle pickup motorhome, weighs bout 5000lbs. The front axle is actually the original old 5 bolt pattern and I'm not sure if that front axle is different from the 6 bolt one and if it even matters or makes a difference for it being a motorhome and a diesel engine swap maybe going to make it to heavy for it?? that's another question I have. But it does have the good rear axle that got upgraded just that year and up for these motorhomes. Anyways I want to swap to the 2lt and maybe even the 2lte. The most common option I see and like is buying a 1984-1986 pickup 4x4 5 speed manual sometimes 2lt or just the 2l here in united states in bad to ehh condition. I like this option because I want everything to look like original stock upgraded 1986 Toyota diesel. If i get the 2l I'm thinking of buying the turbo kit on ebay maybe with an intercooler upgrading to the 3l head due to the over heating issued cracking 2lt heads and raising turbo to 12psi. I'm thinking to maybe put the other truck back together also to re-sell as a gas truck. But anyways so to begin I'm kind of lost in a few areas here, will the 4x4 diesel bell housing bolt on the auto transmission that i have now then I just need the 2wd auto 2lt computer or what?? Can i remove the 4x4 option from the tranny if i decide to swap the 2l engine with the manual tranny that it comes with if so how?? Will I need to get a different computer one originally for the 2wd auto diesel?? For the motorhome i definitely want to keep it rwd that's not an option to change, less overall weight better economy for me. I can deal with the 5 speed manual, i kind of like the idea of it, but im also very happy with auto trans so which ever scenario is cheaper, works better or both. I've seen the kits to rebuild these engines and trannys on eBay for decent prices. I have a family owned auto sale business equipped with a nice strong at least 20ft hydraulic lift. plus engine lifts compressors and plenty of tools. and my step father is a decent diagnostic pull out put in mechanic but never worked on diesel engines before. What do you guys recommend? Any input would be GREATLY appreciated I've been planning this for over 2 years now saving a decent amount of money and spending a lot doing a restoration to my rv that I bought for 1,200$ I want it to be an icon for economical innovative off the grid living design utilizing solar panels to power home electrical living and the option of using bio-diesel. I personally deal with web management and I'm a project consultant at a Miami online based product development firm. This Toyota motorhome truck is my dream project. Thanks again
