turboandrew said:If you have the OS giken for the 2JZGTE, it is possible to use it. It will require slotting the holes to match the bolt pattern for the 1UZ crankshaft, and it will also require milling off the teeth and grafying on the 1UZ ring gear.
But it you want a 2 or 3 disc clutch (and you don't already have a OS giken), you might as well look at what is being discussed in this thread.
