reality on H22 engines

[beastfromeast]

Alright, I find an H22a J's for 3500 bucks canadian and a US version for 3200$ can. should i get the japanese one or it's gonna be too complicated when the time of changing parts will come? Drift, when you talk of low octane fuel in America, does a 94 octane fuel is still poor for those engines? I can even full my tank with 96 octane fuel.

Peace y'all, Raph...

Japanese engines are less restictive than American versions. As far as I know, you will be better off with a Japanese version

they also have more horsepower some of them come with atleast more than an extra 30 horsepower except for the new 2001 models they r also coming as the japanese engines and that i'm still on the look out

why do people keep insisting on believing a lie about japanese spec motors when i just debunked it about 12 posts ago in this very same topic? read the whole topic, and get educated


as for Canadian fuels, 96 octane should run it decently, and still produce near spec power advertised for J-spec motors.

as for changing anything... like i said, there's nothing to change.

Is that true that JDM's H22a can rev near 11 000 RPM?

And if I buy the JDM, will I get any problem changing the pulleys, finding headers, throttle body or any other improving parts? And also, does the flywheel and the clutch could be changed for better one or are they just fine as original?

I really don't know which one is the best here in North America. One of my friend tell me not to get a JDM and he says that USDM are easier to tune here in Canada, but another one told me that the JDM is also easy to tune, that it's just a little more expensive changing parts.

What do you think?...

Peace y'all, Raph...

The parts are just as easily interchangeable for a USDM and a JDM. I have a JDM in the shop right now and I bought a flywheel, clutch, and Quaife LSD so far all for a 'US' engine and they fit fine. You should've been able to read by now that there are no structural differences really between the US and JDM ones except for the compression ratio, gearing, and whatever other little things there could be.

How would putting a low compression head gasket on a JDM H22 affect the HP and torque or how would lower the compression affect the engine in general?

http://www.h22a.com/specs.html Maybe this will help you answer some of the questions that you have about the difference between USDM and JDM.. I have a JDM H22 and have no problems putting USDM parts on it..

compression is a form of power. power comes from compression. the more you compress, the harder the pistons move up and down, making more torque, and horsepower is derived from torque. when you add a thicker head gasket, the volume of the cylinder chamber increases, putting less pressure in the cylinder chamber, and when there is less pressure, less air will be sqashed, meaning the compression will be lower.

SAo basically, lowering the compression of a JDM H22 will decrease my HP and torque, but will make the engine better to turbo, right? I should be able to make the decrease in power by the addition boost I'll be able to run because of the lowered compression too, right?
