what is the diff. in h.p. between jdm and usdm h22a

 

JDM H22A= 200hp 161lbs. of torq.
JDM H22A Type-S= 220hp 161lbs.of torq.
USDM H22A1 = 190hp ?trq.

 

I say go with the JDM H22A. You can get it for around 2k shipped from http://www.Osakajdmmotors.com They want about 2900 just for the Type-S motor.

 

Danm thats nice got any pic?

jdm motor has slightly higher compression, yielding 5-10 extra hp...

 

Jdm H22 is actually 197hp, cause in jdm land they measure in ps which 200ps converts to 197hp. The Type-s is actually like 217 hp. The USDM H22a is like 156 lb/ft torque.

 

Also I read that in Japan they use higher octane fuel than we do, so that along with the higher compression pistons is what gives the JDM motors more power. So really the rated hp for the JDM motors isn't that much over here since we use lower octane fuel, well in most cases.

Correct me if I'm wrong, but this is what I read somewhere.

has anyone ordered from these ppl bfore??

 

h23 vtec ownZ j00 all

 

Actually they rate their octane using a slightly different method, so their 98 octane is our 93.

 

ah...ok. I quess I was wrong. Thanks for clarifying that for me.

cheap jdm motors here.

 

USDM > jdm bandwagon.

 

usdm is supposed to be easier to swap though isn't it? heard something about the distributor being different i thought and causing problems down the line when it's time to replace it. i've been thinking i'll just swap a usdm in since i want it done within a weekend and so i don't have to wait 2 months for it to come overseas. that osakajdmmotors.com or what ever, do they have the same kind of sensor and start-up warranty as hmotorsonline.com does? having that extra peace of mind seems like a good trade-off for that extra few hundred dollars

 

this is true, if i had access to a h23 DOHC VTEC motor I would get it in a heartbeat. you have the extra .1 displacement to improve torque, plus the DOHC VTEC head...mmmm. i think this motor came out of the accord SiR-T wagon.

 

Aren't all of those measures at the crank? I took my jdm H22a4 to the dyno, and you DON'T see those readings. If you can, ask around, I dont' have the link, but there is a link to H22 dyno readings telling you what ecu's they have, all their mods, and their numbers.

 

JDM h22a4 eh? Someone got owned by being a bandwagon jumper or doesnt know what they have. The 200hp rating on the H22A is flywheel. What did your car dyno? Is it an H22A4 or an H22A?
