To be honest i think the 190bhp is the only 2zz available anyway? With no cat it should be 195bhp or maybe a little more at a guess.

Either way i think a 2zz mk1 would be a great conversion, not as "set your hair alight" as the v6 or 3s-gte swaps but far less intrusive for those wanting to keep it with the same characteristics as the 4age.
