    200whp probably isn't going to happen with bolt ons. if it's a genuine type R, save the money on the throttle body, the type R works great. same goes for the cams. the exhaust manifold is probably the best header for b series vtec motors par none (with the exception being a hy-tech header, which will run you about $1k.) since it'll be swapped into a civic, you'll need an intake anyway, your stock plumbing wont fit. an exhaust is highly recommended. that would probably get you in the ballpark of 170whp. assuming the b18 is healthy.

    if you're dead set on making another 40 or so horsepower, you'd probably kill your midrange in the process if you stick to N/A. turbocharged however, you could easily reach your power goal, with mid range that no N/A could ever have (size your turbo on the small side, run 7lbs or less) on stock internals. have it properly tuned and it will be reliable. dont listen to all the turbo reliability horror stories, most of them result from hasty/cheap builds without any proper fuel/timing management.

    you'll find that when it comes to making honda power, some things, like tuning, are worth their weight in naked asian women. ^.~

    The B18C5 is tuned so well from the factory that bolt-on type of mods don't really do a whole lot for it. There's even been examples of people losing power with intakes, headers, etc. on ITR engines.

    Your best bet would be to do some intensive research on what bolt-on parts actually do make power on the ITR (check out www.team-integra.net for an Integra-specific forum) and to look into some dyno tuning with a reputable tuner.

    to get more power out of the ITR you need a real header, like smsp, a big intake, and some stage 2 cams minimum. but i have seen close to 200 hp with that setup.
