The spacer has two holes: One with a regular 1NZ diameter hole in it, and the other one with a larger 1ZZ diameter. You need to attach it so the small hole is facing the manifold and the large hole is facing your 1ZZ throttle body.

Yes I know but if the hole is the same that original, what for use a larger thrtoel if you reduce de diameter. The 1zz throtel is juste to litel larger than the holl of intake manifold, so the spacer can be 2.2 ich to 2 ich, not 2.2 ich to 1.8 inch? I think :P
