The only way to to guarantee a car to be "JDM" is to actually have it imported from Japan with all the original manufacturing characteristics. If it's the case for the the Integra, then it was built in Suzuka (I think). Granted, this doesn't mean that someone who willfully goes out of their way adding JDM parts, specifically crafted for the car destined for the Japanese market, doesn't have JDM qualities. It's just sometimes it isn't that obvious unless you see someone with a DC with a front end conversion. Something like that is a great stride toward the JDM quality. I think a RHD conversion is really, really cool. In my case, with something as insignificant as amber bumper lamps (which are not OEM/JDM anyhow, I'm fairly certain) doesn't really make a difference; it makes my car no more "rice" or "JDM"; something like that goes fairly unnoticed. I only did it because the original lamps were in bad shape. Now, if I were to invest in one-piece lamps, I would be doing it because I feel they look better than the fragmented appearance of the USDM headlamps. If that happens to appear as some as JDM, then it's no qualm for me. Similarly, I don't feel like a ricer because I have a red valve cover, silver painted accents in the interior, or BBS wheels. I like that kind of stuff. The reason it becomes ricer is because someone does something in such excess that the car just looks like a mess. It's a blurred line, but not that blurred. The key is moderationm and if you look at actual cars in the JDM, you're highly unlikely to see something conspicuously egregious in terms of cosmetics, especially if it's JDM. I'm not about a strap an aluminium two-tier spoiler on my car; I would much rather have the OEM spoiler with the high mount light. I'd love to do performance mods, but I don't have the money or facility... The main difference between someone a tuner and a ricer is one takes great pride in the effort to make a car more than what it is. A ricer is looking for instant gratification and unwarranted calls of attention.
