The thing is, that engine is so optimized, that extra power is hard to get. Sure, a B18C can hit 400 HP, but won't be nearly as mild-mannered as the S2000 was designed to be, nor will it last as long.
    Actually its because most imports are optimized to be a LEV or ULEV instead of raw power. And there are people *****ing about 'only getting 60-100 hp' with a supercharger? WTF superchargers only give 45-60hp at the VERY BEST conditions. They should be lucky that you have some kind of magic supercharger that gives them that much power.

    Yeah, i totally disagree with you. Mods arent worthless at all. What if you want a certain body style, and that car is slow? Only thing you can do is mod it. And the reason that mods cost so much is because they have to be tested a lot before they sell them. Like the turbo kit from garnett for the 6th gen accords took over 2 years to develope.

    Okay, are you generalizing, or talking specifically about the S2000, as I was?

    I have never seen any documentation that says superchargerd are somehow limited to 45-60hp. You can add a zero to that number on some drag cars. It's usually a percentage of base HP, roughly 45%. So, yes, on a Civic base 1.5L engine, you'd be lucky to see 45hp.

    By the way, the magical supercharger I was talking about goes by the name of Comptech. They bolted on a supercharger, which brought an S2000 from ~205 WHP (240 at crank) to 289 WHP. That's 84.
    If you need proof, try Vortech's Site
    They show power gains for a variety of vehicles, from Mustangs and Camaros to Civics and Integras. They show a crank HP increase of over 100 for the S2000.

    As for the ULEV, that accounts for some of it, but a lot of it has to do with design. For example, to get the kind of power out of the S2000, Honda needed 11.0:1 compression, thus adding high boost means lowering compression, which means more money. For the most part, modded S2k's seem to run in the high 200's, not much better than modded Integras and Civics. One of my customers at work took a low-tech OHV 2.2 Cavalier and got 220hp without boost or juice. He's planning on slapping on a turbo and hitting the 300hp mark. I won't even go into the Toyota and Nissan 6 cyl's. 600hp without touching the inside of the engine.

    Anyway, in the end, it all boils down to the ever-powerful dollar.

    add one thing to all that was said. Rule of Deminishing Returns

    on my car, intake alone adds 10-15hp. like "wohooo" then I had the ecu reflashed. another 15-20 "wohooo" then i've been looking at rest of the possible mods....exhaust nets me <5hp for $500. a race header if i want to go illegal....not yet. a shorty header is <5hp for $400 too. so at this point....i'm stuck hehe. unless i go out for like cams or FI.

    electronics is so easy. extra DVD drive? just plug it in. want more ram? plug it in u get exactly what u put in. with mods though it's like u put in 500 bucks, doesn't mean u'll get much.

    Well how about this, it works with a handcontroller but maybe with the right software you could find a way to hook it up to your comp? Its not the best looking module but seems alot cheaper if it would work. Then again i really dont know about these things?

    Do it yourself and save a couple of bucks! This is the system that I am wanting to run in the future. The vision is to be able to press a button on my car computer and completly reconfigure my cars fuel maps and boost pressure (once I go with forced induction). Should be possible. Check it out at

    What do you all think?

    I'm turboing my car for less than $1000 and that should get me into the 350HP range and shed a few seconds off my ET after a proper tuning. My engine handles boost very well especially with a compression ratio 0f 9:1 if i grab a grand prix engine and put my heads and intake on it i'll have an 8.5:1 compression ratio. and rand prix engines without the supercharger can be had for $300.
    Cheap power is a GM hallmark
