I am thinking about getting a SC300 as a project car and these are my two choices for swaps. With the 1jz, there is less displacement, but you can easily match the power of a 2j with the right setup. It would cost more to mod the 2jz. Which one would you choose? Also what is the weight difference since the SC is a hefty car.

These engines originate from the Toyota Supra and are known for their potential to be tuned, especially in the case of the 2JZ, up to 900 bhp.

The 1JZ is often sufficient and uses less fuel.

Will it fit a Lexus? Thats a big headache. Why would you want to change the existing unit anyway?

1jz swap can be had for $2000 all day long.. that usually includes 95% of everything u will need,

2jzgte swap will run u a good $2000 for the motor/ automatic trans set.. plus another $7-8k in extras (new wiring harness, etc) there will tons of extra parts needed for the tt 2jz & they add up quickly especially if u buy from the stealership.

Personally, l would just go NA-T.. turbo the existing 2jzge motor. Tons of people have done it. the stock bottom end can hold over 700whp no problem. All u will need is a thicker headgasket, a turbo kit w/ intercooler, some type of engine management (aem ems, etc) & a built transmission. Basically this route makes the most sense because when u swap the 1j or 2j u will get bored VERY quickly with that power & u will want to go with a bigger single turbo which will cost u an extra 10-15k ontop of what u paid for the swap.

2JZ-GTE all the way man. That motor is a freaking beast. It really handles alot of boost, especially if well built.
