875 hp NC Miata engine
Yea, well, sorta...

Here's the convoluted justification for the title: This Ford Fiesta rallycross car (that made 875 hp in Pikes Peak trim, and somewhere around 500 in X-Games trim) is powered by what Ford likes to call a Duratec engine, which Mazda likes to call an MZR, and which is what's in an NC Miata.
Yea, it's a stretch, but I've been on this site enough (that pink abortion on the front page is mine) to know you guys like engine ****.
Anyway, I interviewed the engine builder (Andreas Ericsson, 4-time Swedish Rallycross champ), and wrote it up here: Inside the 800-hp Olsbergs Fiestas - update 1 > MotoIQ > Magazine Articles
I'll be getting more info on the engine in some follow-up interviews, so if you've got some geeky questions, ask them and I'll dig for deets.

The DISI turbo is just one variation of the MZR family. Every current Mazda 4cyl engine (in this country) is an MZR. Most Ford Duratec 4-cyls are also MZRs. Both companies are less than rigorous in their naming, though. Duratec is used for Ford-designed V6 engines, Volvo-designed 5-cylinders, Mazda-designed 4-cylinders, and a few more. Mazda also puts the MZR name on a smaller famliy of 1.3-1.6-liter engines that are unrelated to the 2.0-2.5 family.
Marketing people should not be allowed to name engines...

^^^ Word up dave
The DISI is a duratec/MZR bottom-end (same as a ford ranger!) with a DISI head... the Formula Atlantics motor you mention is the bullet proof Cosworth YDX. 300+ hp NA
The anti lag system is so sick!!

Hmmm, never noticed them call it a YDX before. It's an MZR. I've been in Cosoworth's engine build shop and seen them. There is no doubt what kind of engine they are. Wonder if that's another marketing fuckup?

Almost...the only major difference i see at first glance is the valve cover, its a stressed member for Formula Atlantics

Im pretty sure Cosworth named it

Dave, I just realized I am familiar with your writing as well, Ive spent many nights as a young kid sweating over your tech articles in SCC! At one point i felt like SCC was the only mag I would buy, mostly because of the additional tech it offered over the other newsstand mags...which lead into a career BTW!
Boy have you taught me a thing or two...Thank you.
BTW does your pink miata run in the 24 hours of lemons... what a fantastic event!
Enough bro-mance... keep it up man!!

Beating you up because it would be hard, or because they thought it wasn't a good engine?
It would be exceptionally hard to do, and turbocharging a 1.6 is so damn easy it doesn't seem like it would be the most efficient use of time and money. Still, the result could be quite good.

The MZR has a greater potential for cubic inches and greater power potential than the BP. To beat up on the Honda boys, you better be packing some power. I think the MZR in a Miata could do it.
