i did not post any automatic tranny specs since i figured people
with that transmission are not into performance or technical information. sorry.

Not true at all. Just because we have an Auto
doesn't mean we are not into performance or technical information.
Remember, you *can* shift an automatic, you just don't have to.
If you have the info on the auto, please share.
BTW: thanks for the great info!
:D

Anyone know if this block is Open or Closed Deck? If closed deck then getting lower compression pistions would be a good option, no need for re-sleeving.
I'm debating wether or not to do up my Echo (05 Echo hatch that I bought as my daily driver/winter beater ;) ) Or to just keep building my Civic.
Civic is a great platform for a fast car however, I REALLY like the Echo and I think I rather do this up but it being a new car and not many people modding them (hardcore engine mods) is a little scary for me.
It's so "cookie cutter" on the Civic to get good power.
This engine is good, 1.5L DOHC with the technology it has..a lot of people have 200-300whp in the 1.6L SOHC honda motors or even the 1.5L SOHC Vtec JDM honda motor.
Let's get some people develloping engine parts!!

1495 cubic centimeters

-the 1NZ-FE 1.5-L puts out 81 kW (110 hp) at 6000 rpm and 143 N•m (105 lb•ft) at 4200 rpm.

1299cc
-81.0mm bore
-63.0mm stroke
-11:1 compression ratio
-129kW (175hp) at 9800rpm
-141Nm at 7000rpm
You'll note that the torque is quite close to the 1NZ-FE while the horsepower is significantly higher even though it's 200cc smaller. So, why can't Toyota design an engine like this? Suzuki several ago, and now some 1.0L engines are at about this level of horsepower. Yeah, I know emissions are much more lax on motorcycles, but I still think there's lots of room for improvement.
Of course, it's not performance that draws us to the Scions. I want an xB in spite of it's unexciting engine.

In a word, it would suck.

If you want performance then you must sacrafice something, and that usually is drivability.

599cc four cylinder 16 valve
109bhp @ 12500rpm. Torque 63Nm @ 10000rpm
(it comes bolted into a Honda CBR600)
Yep, it makes the same HP as our stock Scion engine with less than half the displacement!
Would I want to drive it? No way! Having to row an 8-speed gearbox to keep the thing on its narrow powerband would be a colossal pain! Perhaps the coffee-can exhaust crowd might like it for the sound, but as a driver, forget it. I don't even like to take my xB past 5000RPM.
Small high-revving engines works fine in a motorcycle application because the rider seldom needs 100+ horsepower, but in an automotive application the driver would call upon the full capability more often.
Other vehicles have made the mistake of using high-revving engines. Both the Ford Taurus SHO (Yamaha engine) and Toyota's own Matrix XRS turned out to be disappointingly pokey unless their drivers were willing to scream the engines.
Remember that the Scion was designed as a urban vehicle for Japanese streets, using as many of the original Echo drivetrain as possible. Yes, we got a very close-to-JDM vehicle here, but we got some JDM disadvantages as well!
There is no substitute for cubic inches.

That is the entire point of valve timing. To eliminate the compromises forced by choosing cams for low, mid or high RPM power.
If you wanted to make it better, then they could have VVT-i on both cams, or upgrade to VVTL-i. A VVTL-i 1NZFE could probably make closer to 130 hp without sacrificing a significant amount of fuel economy (if any) but it's cost prohibitive in such a cheap car so don't count on it.

Does anyone know the firing order for the 1NZ? Yea, inknow I could go ou to the car and check ... but I am at work and it's too cold.
Never mind ... another day and it got warmer.
