why do i repeat ? repeat until it stick in the head.

There is absolutely no obstacle in k20-like engine with ima, the ima is just an update of the old flywheel/starter/generator; it is just better there is no drawback at all.

but you still would not get the MPG that you get with the 1.5, would you. Why bother building a hybrid that gets <30mpg... which is what a K20 CR-Z would have been. A waste of time, except for that small contingent that want the CR-Z looks with the SI speed and power.

the additionn of hp is not incompatible with good mpg

take example of crz modders :

the spoon one gives 145 hp but the mpg drops a lot.

the hks turbo gives up to 200 hp with same mpg than stock and with very little drop in mpg up to 320hp.

maybe the mugen compressor will not reduce mpg, if well built.

and those are all with the 1.5 engine.. not a K20....

and if you push over 160 on the 1.5, without totally rebuilding it first, you stand a good chance of blowing down the road...

and the HKS is a Supercharger, not a turbo (that could be a language thing, so no big deal! I know you speak English much better than I speak French! lol!)

you could build a car with more horsepower... and great MPG.. but then it is going to cost more, too... and restrict the buying market more. So you have fewer people buying the car, so it isn't worth building, not if the manufacturer needs to sell more of the cars to make any money on them.

Nope.....sorry.
I completely disagree. There's no reason why we can't have a fast crz.
No...I won't go out and buy something else!
Honda took a great looking car, a car that looks fast, and made it slow.
And you know what? That's fine for the people who legitimately want a hybrid car that looks great. And yeah it's fast compared to the prius. But there is a crowd that would rather ditch the ima and 1.5 altogether in the efforts to enjoy the car even more. Some people are 1/4mile junkies.....others like auto-x. And I guarantee those people want a more powerful crz. You may not care about power....and again, that's fine. But those of us who do aren't gonna quit "whining" as you so eloquently put it...

FYI testing by the big guys (Mugen, HKS, and a few others) shows the stock motor good to just under 200, then rods go.

160 was found to be reliable no matter how hard you push it.. you can probably hot rod it all the time at 160 without issues. Run it that way at 200, you will blow it. Yes, it will handle 200.. but not for long.

and with some of the people posting on this thread.. I would suspect they always push it hard. So I was being conservative. Why do you think Honda capped it at 160 on their Higher Performance concept?

My point is just that the fun car with power you are looking for may be also hybrid and still have good mpg. And it can be in the great body of the CR-Z.

I have read about racecar engine that can be set to have good mpg when the driver want, that is another technique called "digital fuel injection" meaning each cilinder does not get fuel sometimes, when ecu sense no need for power. That is included in the V10 of Gaillardo superleggera. That is also on another form in the future BMW supercar. When you depress the throttle, the engine is a racecar one again.

I too see the crz as a tesbed fo the future of fun cars, and proud to be part of it.

about hks, i was mistaked by the shape of their supercharger, it has the same shape as most turbochargers. So Mugen is going the supercharger way too.

be it a turbo driven by exhaust, or a compressor driven by driveshaft or belt to it, i don't like them because it makes the engine more complex, with also the need to cool down air etc.

But anyhow, those systems tend to give power from small displacement engines, and can do that without much negative effect on mpg.

Maybe the only error is that crz looks faster than it is, but this is the first time i want to tune a car, because it is impossible not to.

here is where i am :

this crude bit of plastic is giving me maybe 4hp and a lot cooler temp intake.

yes the rods are gone @ 210hp and 247nm (photos of broke engine on hks site)

The CR-Z might have broken the 40 mpg / 8 second 0-60 second barrier if Honda designed their 'performance' hybrid engine with a 91 octane minimum requirement, which most sports cars run on. The CR-Z has a 10.4 compression ratio using 87 minimum octane, which is impressive in comparison to Honda's 100 hp per liter K20A2 engine with an 11.0 compression ratio using 91 minimum octane. The 76 hp per liter CR-Z gasoline engine is probably the upper limit for a sohc engine, and a dohc engine option might not be cost-effective for CR-Z market size. Anyways, a $25 fill-up with regular is a very pleasant experience.
