If you haven't bought it yet, I would first take a look at some other similar options. I bought my car before I did any research on engine options, I'll never make that mistake again, I would have got my exact same car but in the XLE trim with the 100hp/liter engine(1,8l 2zz-ge instead of 1zz). Others include the mini S with the 1,6l turbo, there's the new Ford focus with eco boost(has the new Honeywell turbo that just blows all other turbines away on technology, turns the exhaust 90° before it hits the turbine allowing far faster spool times, Honeywell changed some other things as well), Chevy just released their 2L turbo diesel they claim 46mpg on, scion has their IQ which may be worth a look if it has an available performance engine. I think a small powerful four will always be cooler than a powerful 6-8, power from a big engine is expected, power from a small one is impressive, measure power on a power per liter scale, not overall power. Like I said if you haven't bought yet, don't make the same mistake I did, research, research, research, find the best car with the best engine option. I assume your after fuel economy which is why I'm listing other small cars, at least check, I just looked and for 2013, fists got the 1,4l turbo engine, twin intercooled, 135hp@5500 & 150lb/ft @2500-4000, get this engine, you don't have to get the absent edition to have it either. At 1,4L and factory 135hp, all you'd need is a high flow air filter to tack on the extra hp to achieve the gold ratio of 100hp/liter(more powerful than the corvette LS7 427 rated at 550hp/7= 79.2hp per liter) and 150ft/lbs starting at 2500rpm and holding flat through 4000(yes we love what a turbo does to that torque curve) will have you extremely happy with this decision. Rather than doin what most do and buy first, then wonder what they can do to increase power and its far cheaper to just get the factory turbo, it would cost in excess of 3-4 grand to add the twin intercooled turbo and tune it if you decide later that the 100hp and 98ft/lbs the base engine has isn't quite enough to get your jig on. Be smart, do it right the first time, and you won't want to get rid of it a couple years later.
