Has anyone in a NA 1.8 even come close to the NA 1.6's?
Um, yea. There are a few very fast ones on the west coast and a couple of them have beaten Mr. Hollis on occasion. They just haven't shown up at Nationals. Andy has actually sold his 1.6L Miata recently...
I've driven a couple of decently prepared NA 1.8L cars back-to-back with a decently prepared 1.6L car and I was quicker in the 1.8L cars. That certainly doesn't prove anything but if I were to build an STS2 Miata, I'd start with a 1.8L car.
I honestly don't think either car are quite as quick as a CRX at the moment but it is very close and I also don't think it would take much to push them over the top.

How much fast in ST trim is a NB 1.8 vs a NA 1.8? AFAIK, its a little more power and a little more weight for the NB.
I don't think anybody really knows the answer to that one but from what I've measured, the "little more weight" is in the neighborhood of 25lbs which isn't much. There's usually a bigger variance in driver weight.
As I said before, the NB's not only make more power but they have better gearing than the 1.8L NA's. They are noticeably quicker and they also seem to respond slightly better to bolt-on's from what I've seen. There is a reason all the fast NA CSP guys are running 99+ motors.
I think it's also easy to understate the effect of the subframe geometry change in the NB. Having owned way too many Miatas of all different years and driven even more, it's amazing how much difference it makes modified suspension or not. Check out some "action shots" of a stock but well prepped NA R-package Maita -vs- a sport package NB Maita like the Monroes currently own and it is fairly obvious even outside the car.
Does any of this matter at the local level? Probably not so much. And honestly it doesn't matter much to me what new classes we create or what rules we bend as a club. It just seems like there is always a bunch of hate thrown at the current rule set we *voluntarily* choose to abide by with very little perspective on how they came to be. Or maybe I just feel like playing the devil's advocate this week-- who knows?
If we do decide to allow NB Miatas with torsens into STT, I may bring out the 'ole NB just to see what it might do.
