Everybody seems to like to tell people to search, but for some reason I can't resist making suggestions. Here goes.
The more efficient the manifold is, the more power you can make overall and the more power you'll make at a given boost pressure. Using that as a criteria, three kits come to mind: Ptuning, Full Race and Pfab ELT. Those are all very efficient manifolds and will either make big power or make good power at reasonable boost levels depending on what you try to do.
There are also a variety of "sidewinder" kits that seem very efficient. InlinePro, Mase, FullBlown, AFI and Synapse are some names that come to mind. (Let's hope my memory is accurate.)
Log manifolds can make power, but you've gotta force higher pressure through the engine to do so due to their restrictive design. Probably not a good choice for your goals.
400-450whp seems to be reasonably reliable for a street turbo S2000 on pump gas / stock motor internals, and is consistently do-able using a variety of kits. If you want to get too far beyond 500whp, you'll need a big turbo and some combination of meth injection, race gas, a thicker head gasket or a built bottom end.
The GT3071R and GT3076R are well sized to give you fast spool and solid power (up to ~500whp) for street driving an S2000. If you need more power, you'll want to look at a GT35 or GT40, but then you start losing bottom end power and having to wait a bit for the turbo to spool. Remember that while racing, waiting for spool means watching the other guys leave you behind. Also while racing, having a big turbo hit boost mid corner means you're spinning off the track, game over.
Every kit can be upgraded or changed to suit your tastes. Some people try to swap manifolds or turbos. I'm one of the people who bought a Greddy kit and was thrilled with the low end power but totally disappointed by the lack of top end. Looking back, I wish I'd started with another kit. I'm glad you've caught on to its limitations.
Finally, the S2000 is a reliable street car for normal daily driving but is also somewhat fragile if you beat on it. Some folks I know have blown diffs or broken axles or transmissions just launching a bone stock car hard while racing. Add forced induction and you're just making the engine a lot more powerful than the rest of the drivetrain can handle. A 700hp engine would eat trannies and diffs for lunch at the track, so you'll need to be prepared to spend big $$ on upgrading the rest of the car to handle that kind of power. There are a few people who do race turbo or SC'd S2000's, and you'll find their threads here describing how much effort they go to in order to handle the power. Some have great luck and no problems; others have a long list of woes.
Anyway, welcome to the community and good luck! Make sure to plan your upgrade path before you start spending tons of money.

Wow see this is the kinda information I'm looking for thank you very much for giving me your insight on good turbo kits and kits that give a good kick throughout the whole power band I'm really impressed by the full race kit with the gt3076r but after that I'm kinda lost on what else would I need to do aka breaks I haven't done much research in breaks I looked in little into gear set for 6th gear I think with the full race I should go with the 4.4.1. Then again I've never tracked an s2000 so that's prob a huge downfall coming from not yet tracking it to get a feel of what it can do stock. I'm pretty sure I've decieded on the kit. Full race and then the aem fuel rail. I have no idea about injectors yet. Haven't learned much about those yet. and a good clutch to handle all that power.
