take a look at the 3rz data thread on the engine/suspension side. it's about the same engine. same bore, shorter stroke on the 2rz. i like the 3rz better but you can find the 2rz cheaper. once you mod it for a 2rz, you can bolt a 3rz in at your leasure. i think you can even use the 2rz computer on the 3rz.
