A new 2.1L, 10,000 rpm, 325 hp powerplant. This has Caterham written all over it 😁

Probably too costly for mass market manufacturer like Caterham to put in but I'd love to know what it's priced individually 

 

Exhaust is on the proper side for Zetec even. I'd sell all the superchargers in a second for this platform

How does this differ from a Millington Diamond?

I think Cat is backing the wrong Horse.

Already asked the question.  The production run is limited so not enough for Ford and Caterham.  The per unit engine cost is roughly double a 620R Duratec unit set up (incl. the roots supercharger).  Obviously this comparison is flawed as it does not cost in changeover in ancillaries and installation elements needed if you were to productionize the engine in situ in a Caterham - so cost differential would be higher in reality. 

 

The 2L Duratec with supercharger is slightly heavier but it can reliably produce 350hp at 8000rpm in a track setting (when using the Partridge Green Motorsport modification package that unlocks the Caterham ECU and fixes the TPS and other design issues unaddressed by Caterham).  Photo of that engine package.

Different engine design for a start - no common parts to exchange.  The Millington engine had its early origins in the Ford YB Cosworth - block recast in aluminum, head changes (new valve angles), and so on.  A lot of work - the current Millington engine is a LONG way from being a YB Cosworth engine.  The Millington engine is designed for competition so it has a refresh life that is shorter than what is accepted for road going production cars.  I thought long and hard about using one in a Caterham and visited Millington twice.   Its a tall engine - using one in a Caterham SV was always going to be a challenge.  Weight is about the same as an equivalent Duratec package.  Refreshes would have needed to send the engine back to the UK - something that is fraught given EPA restrictions on engine imports for cars.

If you want to see a domestic engine that could make similar power, look at the Polaris Slingshot engine. It has 3.5 inch bore and would be capable of the engine speeds in a racing application. I might suggest a slower speed for something on the street.
