btw 2.2ltrs

dun forget Altezza RS200 's engine
I think it is the 2nd best NA engine

Thats for sure. However, saying that turbo engines can't be as clean as NA is wrong. In fcat turbo engines are known to have less emession " known fact and some reading and searching will confirm this"
Honad is environmental friendly but they don't like turbos because of reliability issues. BMW tags alone with them on this part.

aluminum block are also better at dissipating heat but they also warp if over heated.

I shrugged it off, but started thinking about it, and really couldn't come up with a more powerful 4-Cylinder off the top of head. The STi/STI is rated at 300HP but it does not dyno as high as the IX. So is there a more powerful 4-Cylinder out there?
the STI at 300hp makes 120hp/liter (2.5L) but has more torque than us
if it is currently at 286 crank hp, then in theory it is making 143hp/liter. for comparison, a 500hp Dodge Viper is making 60.24hp per liter (it is however 8.3L yikes...) so if there was an equivalent V10 powered evo, in theory it would make 1186.9hp...
remember folks TORQUE makes a car fast, not HP

Aluminum blocks are lighter and EVO X will have one.

as far as the EVO X goes, i will not buy 1 for that reason. Al blocks are best suited for NA or S/C cars. this is why STI's & WRX's melt piston #3 when they turn the boost up real high or slap on a big turbo kit.

But you are incorrect about the reason being due to an aluminum block design. Reason it cannot run high boost like the EVO is due to compression/pistons/rods, etc
I hate to say your wrong again, but I have several friends that run 25lbs+ on built motors and yes, they are daily driven. Meaning not only do they drive these cars everyday, but they also drive long distances to get events, shows and races.
This is a link to just one site that builds motors, and they are pretty well known:
JG
You can also look up golden eagle.....many others as well.
There are many "hondas" that are running around with not just motor swaps, but fully built motor swaps with turbo. Example: www.stage6motorsports.com has a blue CRX with a built b20 and turbo.... 428hp last i knew at the wheels. This is a car that I saw on a daily basis when I lived there. Me and wrick (Pensacla) started a car club with a couple others, and we had several quick hondas in it. I had an STI for a while with TBE, ran 12.69@108, ran my buddy with the crx on the highway from a 60 mph roll.....within 15 seconds or so, you could barely see him anymore.
Don't mean to be offensive but I think it's good to know if your not familiar.....
*EDIT* heres a direct link to the CRX
