this model is not equipt with the 475hp...the 475 does < 11.87s in the quarter...actually you buy this engine cheap schiller for the standard monster miata....conversion kit outta california cost around 4 or 5 k for the do-it-yourselfer....engine, trans and rear diff are also needed in the change-over....tons of mustangs, thunderbirds and cougars in the junk-yard and if you want new go to ebay and pick up a crate engine to modify....and as for project car cost you can pick up a miata with a blown engine for way less than 6k....the blue book on a 90 miata is around 2.5k...as for ferrari doing it all wrong no they haven't...they are a business...thats their job making money....they are nice lookin, fast, great cars but it would piss me off to no end if some guy that sunk 20k into a beater of a miata blew my f/n doors off...maybe if you tell your "guys" at audi and ferrari you will get what you really want more than anything in this world...an audi engineer in your ass and a ferrari engineer in your mouth
