Or course, the obligatory "it depends on what you want out of your car" applies here.

If you just want my simple opinion? (Keep in mind I don't know what you're trying to achieve)

The GS is a large body luxobarge and should be propelled by a worthy power plant with a minimum of 8 cylinders. Not just for power, but for refinement and ease of mobility (read: torque).

Don't get me wrong, I LOVE my 2J, and the noise it makes tightens my pants everytime. But save that powerplant for a chassis more suited to high revving hooning. Like, SC or IS. My GS makes a sweet noise, too. The intake growl is a thing to behold on the 1UZ.

I love both my cars and I drive them very differently. The SC I drive like I'm in high school. The GS I drive like a professional businessman.

So it comes down to what do you want? A big lux cruiser that's fast, and high revving making a lot of noise? Then slap the 2JZ in it. Nothing wrong with that.

Now if you want a mild setup that sounds great, is decent on fuel, and headache free, GS V8. One hell of a car. Especially since the V8 in these types of chassis are disappearing. Enjoy while you can.
