It's true of most, but not some of my favorite Japanese engines: RB26DETT, VG30DETT, EJ22T, 2JZ-GTE, KPGC10.... It's as if they do amazing work with some new, unexpected car just to get your attention. Then, after a year or two, they gradually reduce the quality, performance, longevity, robustness...I don't get it. It's very frustrating, too. It's as if you have to compromise: get a new car, but search the junkyards for a better, older revision of the engine you have, or take your chances with a complete older model -- with an engine you'll probably have to take out anyway to rebuild it.
I mean, why don't they do what Ford did with the Mustang SVT? Sure, the release after the Cobra R wasn't up to snuff, but you can't tell me the 2003 model isn't better than the '99 R? Look at the evolution of the Corvette: phenomenal, to say the least. The Camaro's looks may not be my cuppa', but it gets better each year, too.
Then there's the German market, where they stick with what's good, beat it to death, only to replace it with something even better. The VAG 1.8T, BMW 3.0i (and 3.0d), M-B AMG 55 (compare the old 5.5L to the new, blown 5.5L monster). Italian marques are just as good, only they try to improve the whole car -- including, and most importantly, reliability...and they do okay...but at least they try.
What does Japan do? They say "Hey, wasn't that Skyline great? Well, it's going away now. But here's a nifty Maxima for you! Check it: 4 seats and a Bose [ed: yech!] audio system. Keen!" Sorry, charlie. I wan't my old, fugly-faced GT-R. That thing could take the kind of crap driving I dish out. All those engines I listed before are long gone (including Mazda's twin-rotary, which while it needed some work to pump out serious HP, it's still great).
So I want 450HP out of my WRX (no, really, I do...in 3 years). Can I do that with the existing EJ20? No, I have to call up COBB tuning and get a new block -- probably the 2.5L fully-closed-deck -- pistons, heads, etc. Basically, a new engine. I think a lot of people are going to be blowing up a lot of WRX engines when they get too excited about how accepting to tuning the 2003 EJ20t is. :-/ :shrug: Well, there's always TVR....
