It depends I payed 550 for my 3.4 it came with everything computer wiring all the components I have to buy oil pan with rear sump that 245.00 from sky manufacturing, convert crossover pipe to other side and I'm using a 1989 Toyota pickup that had a 3.0 so I pulled motor and it bolts right in too the factory 3.0 location you use 3.4 clutch fly wheel 3.0 shift fork and throw out bearing and only complicated part is wiring which there's allot of write ups about it to make it easy.. I may be into the motor swap a grand at the very most also there's no distributor to deal with and makes it simple under the hood
You can use a v6 trans or use Toyota 4 cylinder turbo trans using 3.0 v6 bell housing
