I've come across a great deal on a 98 Tacoma engine with computer, 5spd transmission, transfer case, exhaust, radiator and accessories. Will the engine/transmission/transfer case fit in my 86 4Runner? If so, what would the swap entail? If the transmission/ transfer case won't fit will I be able to swap just the engine without much trouble? Thanks!  

yea it will fit with out to much trouble!   The wiring is the real brain teaser.

Thanks for the reply, Dirt. Know of any resources that might give me some detailed information on the swap?
