The 1JZ is a 2.5 liter bi-turbo 6 cylinder. The other engine you are talking about is the 7MGTE, which is a 3.0 liter single turbo 6 cylinder.

Both would require about the same amount of work. The 1JZ probably offers more potential for power and durability, but less torque and less readily-available parts.
