Posted: Tue Sep 22, 2009 5:09 pmDoes anyone know the specs needed to be machined on the 22r rods to make them fit the 1mz crank? Thanks

Mill down the big and small end of the rod .270 (.135 on each side)
Modify either a set of 22R rod bearings so that they fit the new rod width, or modify the bearing locator slots in the rods.
You'll have to radius the big end to get it to fit into the cylinder bore. *OR* I think boring the motor .040 would do the trick.
Also, be advised that you are adding close to 100 grams of weight to each cylinder. Adding metal to the counter weights on the crank will be necessary.
Good news, the Eagle rods will be tons of overkill on this engine. I suspect the block will fail before the new rods.
