I have slayed S2Ks on the motor. They do not like it.

They do handle boost well, and whoever said that the high revs make for more useful power on a large tubro nailed it. Lots of Hondas do this. You loose response down low, but shoot if you can rev to 9K and you start making power at 4500, thats pretty good powerband, and you can get away with some pretty cool gearing too. A 2.2L with high compression will spool a 35R on say a .86 T3 hotside pretty well. Shoot a 2L at 8.5:1 comp can spool a 35R to 10-15 LBS by 4500 if its done even reasonably right.

I dont like those things stock (to much weight, not enough TQ) but with forced induction they do tend to make sense. Sort of like 350Z ironically enough, though they are from completely different philosophies.

It is an F20C (s2000) powered Miata. I am in the process of putting a turbo charger on it. It is a very exspensive build, to do right. Once it is done I will share all my tuning info and dyno numbers. But 450 ish HP on an elt manifold with a genuine Garrett gt 35 turbo 14 -15 lbs of boost is easily obtainable. The rumor is that this boost level will allow a 100k of durability as well.
In for this ^^

My car trapped ~1 mph higher, yet the F20-powered Miata weighed slightly more and wasn't running quite right yet.

Lets not knock these cars too hard. You can pick them up under 10k all day long now and they are stupid fast stock on a roadrace course. As soon as they start dropping to the 5k range you will see a lot of miata owners jumping ship.

where are you seeing them for under 10k all day long? maybe an 00-02 with super hight miles, but anything 03+ and with decent (under 80k) is still well above 10. The ap2's are still in the 15's

^ This! I bought my 2000 ap1 (first year) with 44k on it in February of 2009 for $13,900. (Then sold it 8 months later for $14,500)
