Already did send him an E-mail. No reply as of yet, but as soon as I know more I'll put it on here. One thing I know is that the turbo is a td25 GReddy. Does that ring a bell?
Like I said I don't know a thing about miata's except for the fact they look nice, let alone the whole aftermarket products with which you can crank up its performance.

And the engine being cutting edge? I would like to believe so, he is sort of persuaded into doing this. But when I hear what kind of money already went into this engine..

Sorry when i think Greddy turbo for a miata i think "TD04H 15g turbo". There is a T25 turbo. I dont know about TD25. And also i dont think greddy makes a T25, but garret does.
