17 years of messages here have well documented the OEM cams are fine. The VTEC cam is the high lift and it's in the head already so take advantage if it with a lowered VTEC engagement. Custom tune and aftermarket ECU required. I think they all need a high flow cat to work right. Increasing the area under the graph's curve should be the goal, not a single high power number. My VTEC engagement is at 3600 rpm, not 6000 as it came from the factory. Different dynos produce different numbers. Mustang dyno (these are known to be conservative) put mine at 221 at the rear wheels.

E85 is another option. Any significant power increase will require supercharging. Supercharger is a weekend project; turbocharger may take longer and requires more disassembly. Admission prices start just over $4000 and the better seats are more expensive.

The Speed Academy guys in Toronto have access to and tried all the bolt on goodies to their S2000 and didn't make massive power even with ITBs. Their number on a different dyno was less than mine even with the ITBs, massive cold air intake, and big exhaust.

You can spend 5k on a super charger and see around 425whp for an average high boost set up on pump, or spend 5k on stroking your engine to a 2.4 or 2.7 and stay NA and see around 300whp. When you stroke the engine, ive seen some gain difference on after market cams. Like any engine, most internal mods need to work together as a package to be effective, this is especially true on a NA 4 banger, one of which has been tapped out already with precise lift and duration for the stock engine to yield its full peak potential. When you uncork the exhaust with a TP or HFC you can gain the benefit of lowering the high cam/vtec in the 3500-4k rpm range to pick up a sizable amount of mid range power however.

So even with bc cams noting is going increase on the engine? The stock cams is the best right?

Yup

Ok thanks for the help

Your car is a freak, that's a ~235-240whp Dynojet number. Pretty nice.

Tuning the car and lowering Vtec will increase your midrange power by quite a bit. Beyond that its like Junky said there is NA motors that make 300hp I think the J's engine is around that and inline pro but both of those are fully built motors that likey cost double what a supercharger kit costs for less gains. I'd suggest spending a lot of time reading through the Na section before you waste your money and possibly ruin the reliability of your car.

I appreciate your time and I'm going to put the cams idea off and get just a ecu and big throttle body

Seems so.

Car has the ubiquitous K&N FIPK, Berk 63.5mm high flow cat, and Tanabe Medalion Touring exhaust. And a Gernby FlashPro tune with a 3600rpm VTEC engagement. Tuned on 93 Octane. The only other S2000 owner who's driven the car called it a "beast." I'm happy. Hits the rev limited so quick in low gears I installed a red line alarm that counts up as they get close.

Brian Crower Stage 2 cams absolutely make power with a tune. As a single modification, they make more peak power than a 70mm titanium single exhaust with a tune. I've done both setups, both custom-tuned by the same S2000 expert on the same dyno. Swapped the 70 for a dented stock exhaust and the cams and made 4 more whp. The cams do focus the gains all at the top end, though, so don't expect an increase in low-end torque from them.

I can't speak for the Skunk2 cams.
