unless i'm mistaken JDM cars run 100+ octane gas and thats regular daily drivers. i dunno if its that high but its up there.<font face="Verdana, Arial" size="2">Originally posted by spin_r_g:
I have a 94 I was thinking of putting in a JDM h22a I know it has to be 94 or newer. I think it should be fine I just dunno how the jdms run compared to the usdm.</font>
LLL, does the JDM h22a ecu have a fuel cut off or speed governer set really low, like low 100s...110ish or thereabouts? I have a 93JDM h22a motor that I have not installed yet...I have both a usdm and a jdm ecu...which is better to use?<font face="Verdana, Arial" size="2">Originally posted by LudesLudesLudes:
No one seems to know. I have a jdm h22, and I don't think my car will pass smog. I don't know, because I haven't had to do it yet, but I'm not sure how running 10.6:1 compression will affect emissions. Plus, the jdm ECU is different, so that may cause you to fail also. Get the jdm motor, it's much better. Then go find a new "buddy" who just happens to work at a smog shop. Make sure your "buddy's" hand is well lubricated with a couple of benjamins. If you want to go fast, you aren't going to pass visual inspection anyway (that's where most modded cars fail), so that's really your only option.

yup.. i just had my car tested 2 weeks ago... the guys was actually impressed by my car and asked how much it costs.. hehe..<font face="Verdana, Arial" size="2">Originally posted by Mr Ludecrs:
In Wisconsin, all they do is run the car on the dyno thing for a "cycle" designed to simulate city/highway driving. They hook up the tube to the exhaust and that's it. No underhood inspection or anything. Occasionaly, they'll take a mirror a check the exhaust pipes for leaks etc.
Some counties west of Milwaukee don't even smog test. Our Lude is going in soon for it's first test and I'm not worried.

Are they that much faster? I have seen a JDM and a USDM both run at the same track, granted, conditions may have been different but the JDM ran a 15.2, and the USDM ran a 15.3. As far as mods go, the USDM had I/H/E from what I could tell, and the JDM (which my buddy owns) has I/H/E fuel reg. and street slicks. The USDM guy couldn't drive for SH*T, first run he ran a 17 something, and my buddy is a good driver. I think the cali. emissions crap evens it out.<font face="Verdana, Arial" size="2">Originally posted by LudesLudesLudes:
Go jdm - it's way the hell faster. The jdm motor has shorter gearing, higher compression, and an ecu that likes mods better. </font>
That's exactly my point - the usdm h22 & ecu have to deal with all that emissions crap, so they lose horsepower. Also, putting an Si tranny on a H22 will make it a hell of a lot slower. Si gearing is longer than usdm vtec gearing which is longer than jdm vtec gearing. Also, jdm VTEC motors run 10.6:1 compression instead of the 10:1 usdm h22 motors run.<font face="Verdana, Arial" size="2">Originally posted by cantdrive55:

P.S.
oopsie, I fergot, my buddy had his Si tranny on it, I assume the USDM guy had a VTEC tranny.
