I have a 0.020" bore and TRD cam on my 22RE and it passes smog OK, NOx is the biggest issue on the earlier 22REs with the primitive EGR system.

I was looking to bore .030 or .040 over. How well does it pass smog? Do you think it would still pass smog with that?

Mine hits single digits on the HC and CO tests, but gets close to the limit on NOx. Bore should have little impact on smog, still essentially the same basic engine, you are only adding 50cc or so to the displacement.
