curious...how much are they asking for the 3RZ?
just remember that all those parts that you don't have will add up quick. how long are you willing to wait to find all the necessary parts? if cost wasn't a factor, then i guess you could get those parts easily and quickly. but i know there's a budget involve (cheap as possible) hence it'll be alot better finding a complete parts truck.
fwiw, when I did my swap, the donor truck/engine had a busted powersteering pump/reservoir and cracked exhaust manifold. Took me 3 months to find those 2 parts for a smoking price...$35 for the ps pump and $50 for a newer manifold...
