A while ago, I had a link to a website that described all the physical differences between the USDM H22 and the Type-S H22. From what I can remember, it has port and polish, different intake, larger throttle, different valvetrain, a 45 degree valve seat to accomodate the valvetrain, and a different exhaust header.

If any of you have driven a normal JDM H22, the extra torque, even though it's a little, is very noticeable (at least when my friend got his). The JDM H22 has 10.6 pistons, probably higher lift cams, too. The engine also makes a really cool whirring sound when it runs. So if you've ever driven the JDM h22, you'll wonder what the Type-S feels like...

H23 Turbo vs. NA H22. It's like religion and abortion, You can debate it forever. So I won't go into that.

As for the JDM H23 VTEC, it probably does have oil squirters, and I'm guessing stronger connecting rods and crankshaft. Could someone find me a page with complete specs, and I'll ask one of my friends who can read japanese attempt to translate it for us.

I can read japanese and I translated the power for you

JDM h23 vtec-
torque: 22.5 kg/m = 162.74....163 lbs/ft
HP: 197

JDM H22-
Torque: 161 lbs/ft
Hp: 197

The Type S has the mods I listed, and the ontes the others listed too. It is a well built engine.

well, looks like .1 liters dont really dont do jack-sh!t. . .same HP rating and only a tad more torque. Oh well, I'll go ahead and cross that off my "potential upgrades" list.
