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!

Default Car For Sale

Checking if this car is still for sale as this post is almost a year old. If so, has anything changed with it since the time of the sale posting? Please let me know.

Thanks,

Len

Hey Len,
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.

Hey hope you are doing well. Any chance you have just the forged motor for sale and any other aftermarket parts?

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

I apologize for the delay in replying. I had no idea how to get back to the original thread 😂. But yes I am looking for a no mystery one. Also from reading the description it's not fully forged right? It's partial?

yes only forged rods. Which if you’re 400hp and below is all you need.
