[QUOTE="Voltwings, post: 14305210, member: 155561"] Ehh, "lag" is a big grey area. I had two turbos on my Ms3, A gt3071 (47 lbs/min) and a GTx3576 (like 65 lb/min). You can adjust the intake cam (more dynamic compression = better spool), ignition retard (retarding ignition moves the flame front closer to the exhaust valve opening = more exhuat energy) and have a big hp car that behaves pretty well, which my 3071 did. That turbo made 460 whp and about 430 wtq, and drove just like stock around town. My 3576 though i hated the second it went on the car. That turbo had no balls, had no pep, and completely ruined the car, it was basically only fun when my foot was to the ground so i agree 100% about there being a happy median... That being said, that 3576 made 500 whp without breaking a sweat though lol that was pretty damn wicked. I realize i side tracked myself a bit, point being on a log style manifold, (better spool for the sake of top end) which is basically what the ecoboost has with the integrated cylinder head, and the sophisticated cams, i'd be willing to bet most mid sized turbos will behave fairly well if tuned right. Its all still speculation at this point though, Ford basically has the market on lockdown. Name another small, light, "cheap" RWD coupe... Genesis 2.0t? BR-z? Maybe a slightly used BMW to be in the same price range, but thats really it, so assuming this car doesnt outright suck, i imagine it will be a hot contender in an otherwise dull market right now.
