Default Is JDM always a better upgrade than USDM?

What's so good about JDM that USDM can't beat...

Everyone wants JDM this or JDM that... Are there things that should only be bought in the USDM market (or vice-versa)?

I'm kinda new to this whole scene, and want to know the popular concensus.

Thanks!

Who cares where something is made? Buy quality products that perform well. JDM is just overpriced most times, though there are exceptions.

if you are talking safety USDM is better! many times ive seen people talking about swapping bumper supports with the JDM one. its lighter yes, but when you get into an accident you will pay with it for your life. besides, if your insurance company finds out you'll probably have a hefty doctor bill too!

Most imports from Japan are more conservative from their japanese counterparts. I could cite lots of examples but I dont want to mess up the HP rating cuz Id get flamed from all these idiots.

The logic being, if this JDM B18 gets more HP this USDM B18 then there must be better parts inside. So ppl swap for JDM headers, cams etc.

All JDM parts may not be better, and there maybe be better on the market...

If you're thinking about the difference between the JDM B18C and the USDM B18C1, the mechanicals are identical, but the extra 10hp in the JDM engine comes from more aggressive ignition timing allowable by higher octane fuel available in Japan. I'm only 80% sure of this, so someone please correct me if I'm wrong.

a 5 mph bumper is not going to make a difference in an accident where you receive bodily injury, and if your insurance company says otherwise, take them to court.

the bumper only does one thing, it is supposed to survive a 5mph collision with minimal damage so that your insurance doesn't have to pay a lot for stupid people backing out in a parking place without looking.

there are a lot more forces at work if you get into a serious accident, and the 5mph bumper doesn't do anything but get smashed into your radiator. crumple zones and safety zones, and colapsable steering wheel, and a host of other things, but not the 5mph bumper.

JDM is better because I cant go to my Hond adealer and get it. Thats why I like it. Because its pieces that pay attention to the little things. I wish honda had a parts system like VW.

There are better parts, and they are generally a cheaper alternative to higher priced aftermarket.
Plus they are honda parts, so no worries about quality and craftsmanship. May not be the best
out there, but certainly good for the mild mannered driver.

10 Horsepower from ignition timing? What about higher compression, and more aggressive cams for the JDM ITR? Cant that contribute to the 10 extra HP?

There is some guy on ebay selling "JDM" G3 GSR tail lights.
For some reason he had a hard time coming up with a catch phrase about how the JDM tail lights were more desirable than the USDM ones.
The reason is they are the same !
JDM is not always better !
And if anyone is actually impressed when you tell them you have a "JDM this" or JDM that", they should be

No kidding. Why the hell do people always talk about JDM like its friggin' Mugen or SVT or some other kind of tuner? ITS NOT! Jeez...Its like me having a European car in Europe and telling people how I have USDM taillights and front cap. Its retarded. The other stupid thing is all these people spending tons of money to transform their car to JDM spec. So what? For the amount some of these front end caps costs, you could've had the damn japenese spec car imported. Idiots.

IMHO, JDM for the most part means "different." Everyone in this industry has some sort of goal to be different. You get a lot of points at car shows for being different but for me having to pay extra $$$ to be different is not worth it. There are a lot of people that hook up their rides for the sole purpose of being different. Few achieve this goal fully.

So what if your speedometer is in KMH instead of MPH? You probably don't know how to convert the two readings anyways.

So what if your climate control has numbers instead of just red and blue?

The interesting thing is, people in Japan feel the same way about USDM products. Guys over there get the USDM front ends on their tegs like we get JDM front ends on ours. (I personally like the JDM front end better.)

I have one JDM item in my car and that's "My Shaldan" air freshener. I like it not cuz it's JDM, but cuz it lasts hella long and smells hella good.

Not quite true. Sure, some people over there prefer the USDM front, but the majority prefer the JDM style front end. They sold the US-style version over there for a year, and it was so poorly accepted, Honda switched.

That's why it's different-- people didn't like it/wouldn't buy it.

Anyone can say their car is "JDM this and JDM that" but until I see the steering wheel on the other side they can kiss my USDM *** while I'm laughing on how much money they spent on getting their car to look just a little different.

JDM engines have .3 or .5 higher compression then USDM. Thats where the 10 extra HP comes from.

JDM B18C = 10.6:1 compression
USDM B18C = 10.0:1
JDM Type R = 11.1 :1
USDM Type R =10.6:1

jdm b18c's have better cams/compression/header

the gas isnt that big of deal.

I am a JDM enthusiast and i find some of your comments a little offensive. JDM is a style... like anything else. The fact you guys bash it is sort of ludicrous. To each his own eh? Sure i paid 70$ for my amber clock.. but i love it. Oh well...
