How durable are these motors? Revving to 9k+?

shit I didn't know man, every honda my friends have had used a belt or chain and had to be done either 60 or 100k...my mazda was hte same way...I'm glad this one isn't like that cause thats annoying as hell.
hehe yea theres alot of ppl with over 100k with no probs.. other than usual stuff like the clutch... im goin on 70k with no probs yet.. and I drive pretty hard when i do..

I misshifted from 5th to 2nd, wanted to go to 4th. Rear tires locked up and I stepped on the clutch right quick. S2k still fine 
e36 m3 engine - 240hp
e46 m3 engine - 333hp
oh I don't know what its called here but the bmw guys call what I did a money shift

I don't consider myself hard on cars, because I drive smoothly, but I'm not easy on them either, because I like to exercise their limits. I never drive the car without running it to redline at least a few times, and I autocross the car. It's been lowered, has a short shifter, and a supercharger, and it's pushing six years old now, but it's still just as reliable as any other Honda we've owned.
It does drink a lot of gas when run hard, but the joy justifies the price.

Coming from a bolt-on '01 C5 to my '05 S2000, there is a big difference in overall feel. My V8 buddies still trip out when we're rolling down the highway at 4,500rpm in top gear at 85mph.
They think the motor is going to blow. haha.
Anyway, warm the engine up, maintain oil level, and change oil at regular intervals, and you can thrash both the 9k motor and 8k motors all day long.
I have 4,500 miles on my '05 and I am not exaggerating when I say that I've redlined it well over a thousand times and probably hit the rev limiter at least 50 times. It's a lease, what can I say? However, I do WARM the motor up and maintain it with good synthetic oil.

The engine is working very hard at 9,000 rpm. Think about it, 9 thousand revolutions per minute, that's 150 revolutions PER SECOND my friend, if that's not working hard, then I don't know what is.
Bogging is bad for the engine, no question. Honda gives you 6 gears to avoid the bogging you are talking about.
The engine will consume more fuel and have a shorter life at 9,000 rpm than at 2,500 rpm, that is just physics and logic.
Fortunately most normal driving will not allow constant 9,000 rpm. The engine spends relatively little time up there, but every component of the engine is more stressed at 9,000 rpm gentlemen, pleassse.

Maintenance is key on vehicles like this. Like you I drive fairly hard but smoothly. My shifts when I want them to be are very fast but again I'm smooth. I've missed two shifts in my TA in 2.5 years of ownership as opposed to folks who will miss 2 or 3 shifts each time they're at the track. I'm pretty excited about these cars, if my MSFT stock would do something other than stay flat I'd unload it and get one tomorrow 

Yep, I know how to stay off the clutch as much as possible, rev match when downshifting, and make quick, decisive upshifts. Ran the crap out of my C5 for 40K+ miles with several thousand of those miles on the track (road courses in TX) with no clutch or engine or drivetrain problems period.
Honda built this motor with the intention of running it hard. Especially on the '05 model, the powerband is only between 6k and 8,200 as that is where the VTEC cam is roaring. Anything below that and it's a typical Accord.
Look at the stats of the '04 motor:
2004 Powertrain Main Features
The following are the main features of the S2000 powertrain NOTE THE FORGED INTERNALS, OIL COOLER, ETC.:
2.2-Liter (2178 cc) VTEC Engine
8000rpm rev limit
240 hp @ 7800 rpm
162 lb.-ft. of torque @ 6500 rpm
0-60 mph acceleration in less than 6 seconds
Compact, lightweight engine design aids in ideal (50/50) weight distribution
FRM (Fiber-Reinforced Metal) cylinder liners
87.0 mm bore X 90.7 mm stroke contributes to increased torque band
Rigid aluminum (ladder-type) main bearing support, with cast-iron bearing inserts, enhances engine durability
Lightweight forged-aluminum pistons and heat-treated (carburized), forged-steel connecting rods add durability
Full-floating piston pins eliminate piston noise during warm-up
High-volume oil pump with silent chain drive
Compact, high-efficiency oil cooler
Cast-aluminum oil pan helps minimize engine noise and enhances oil cooling
11.1:1 compression ratio
Compact, DOHC VTEC cylinder head and valvetrain
Lightweight, MIM (Metal-Injection Molded), sintered-steel rocker arms
Low-friction roller-bearing cam-followers
Compact, 2-stage cam-drive with silent chain, scissors gears and fully automatic tensioner
Hollow camshafts function as lubrication path for VTEC valvetrain
Sequential, Multi-Point Programmed Fuel Injection (PGM-FI)
Intake system with straight inlet ports and low-back pressure exhaust system
Electric-motor-driven, multi-port secondary air-assist injection system helps lower hydrocarbon emissions
Meets California's stringent Low-Emission Vehicle (LEV) standard
Compact engine ancillary drive system uses a serpentine drive belt with automatic tensioner
Compact engine ancillaries, such as air-conditioning compressor and water pump, save weight and take up less space
Direct-ignition system with long-lasting platinum-tipped spark plugs
Low back pressure, metal-honeycomb catalytic converter
