I’m trying to think of anything and everything but probably missed some stuff. It’s an amazing car. I’ve never tracked this particular Miata, it has always been a street build for me. I’m confident it would do really well if that’s what the next owner wanted to do. This has been a regular driver for me. The 6speed with the Euro-spec 3.6 diff is absolutely ideal for this power level. Long gears, lots of time in boost, and lower rpm’s at highway speed. ~18mpg on e85 and it'll walk most cars both in a straight line and on track. Lots of time and attention has been put into making it turn-key and reliable. I hate to see it go, but I’m moving the funds into my next Miata-platform build!

Not CARB legal. Smog is buyer’s responsibility.
I have 100's of photos. If you want more let me know.

believe it or not it still is. The motor has gone through a few revisions, but is getting a VVT 1.8 soon. I don’t plan on forged internals on that motor so it should be around 220-230whp. Everything else will be the same. Let me know if you’re still interested. You can message me too and I’m happy to give my number to text/call.

I’ve got the forged motor but in unknown condition. Was pressuring the cooling system and after 3 head gaskets couldn’t figure out what was causing it so replaced the motor. That one’s still in my garage if you want a good deal. But I’m assuming if you’re asking it’s because you are looking for a no mysteries complete forged motor
