I want this engine!

Who wouldn't?! ;-) That's a great project. What an engine! cd

And the beauty of it...

...is that there are LOTS of them!

The engine was used in the Mazda 626, MX-6, and more importantly, the Ford Probe GT.

There's an entire 1995 Ford Probe GT on Craigslist right now... ...for $500!!

It's a very interesting project and if that guy who did it would assist, not nearly as difficult as it was for him, I'm sure. I'd like to know how much that carburetor set up cost him. Seems like he did a few things very exotic that could have been done much simpler. Just hard to say how much those things benefitted the end result. What did he say, 180hp at the wheels?

Any idea what the stock motor / fuel system yields horsepower wise (at the wheels)?

My understanding is that the stock KL-DE is about 160, but it can be fairly easily upgraded to KL-ZE spec and that yields about 200hp.

On a purely horsepower-per-hour-of-effort basis, I don't think I can really justify the project, but if I can do it for the fun of the project and do it as a build-up that takes place mostly outside of the existing car and can be dropped in when much of the work has already been done, then I like it for the uniqueness of it and for the engine note you'd get.

Anyone and his brother can throw money and time at a Miata and do a V8 conversion and I can't say that it interests me very much to do what anyone and his brother can do.

:-)

I agree entirely, this car sounds amazing and the motor looks as good as it sounds with that setup. U-N-I-Q-U-E! or at least rare ;-)

The trick is to install an Allison V-12 and have the hood close...

Sorry, but I have deep roots in the UK...

...it will have to be a Merlin.
