I spoke to Element about this same type of NA build, using either stock or JE pistons at stock 12.5:1 CR. They said the same thing, unless you want to build a motor for a ruleset. For me it's more about reliability, since my class's hp/wt ratio won't change. I just wanted a motor with the better oiling, upgraded bearings, valve springs, rods, rocker lockers, etc. etc.
I'm kinda purist with this car. At first I set out to prove it can be a front running car in GLTC, which at 200whp, I did. But the problem is you don't have the luxury of being able to make 215-225hp without a big money build, so then you can't detune to have a flat power curves, which is what all the K-swap miatas I race with have.
That said, I still really don't want to K-swap, simply because that's literally what everybody else is doing. But for guys who want big NA power (or FI), with a MUCH easier motor to work on, that you can buy from salvage yard for $700, it's hard to argue with the K24 swap, fo sho!
