thinking of a sc300

ok so im looking into a 93+ sc300.. i know its a n/a 2jz ge motor. but i was looking to ither buy a turbo package for the 2jz or drop in a j-spec 2jz.. which would be cheaper, also how hard is it to drop a 2jz into the car? and i heard the stock 2jz can handle 15psi with a stock bottom end? true or false? i know i have to do the fuel sys. and other accesory if i stick with the n/a 2jz. so wat are you view or opinions on this project? swap a j-spec 2jz or turbo the n/a 2jz? thanks alot

Why dont u just buy an SC300 with the 1jz motor in it. 2.5L twin turbo. they go hard.
