1jz vs 2jz

i was wondering what is the difference between other than the 1jz is 2.5 and the 2jz is 3.0. thanks for any help

the 1jz has a true sequential set up where the 2jz has a setup where first one turbo spools up and then at the 3000rpms the second turbo is turned on. Both turbos are the same size on both set ups. The big difference is displacement and the 1jz has the coils set right on top of the spark plugs. If you want to know more go to Mike Urbano's web page. He put a 1jz into a MkIII. It sounds like he had a hell of a time doing it too.

Cheers,
Al
