Stock S2000 engine can take... how much boost?
26psi. that's right. The engine is completely stock, save a gasket that slightly lowers the 11:1 compression ratio. Properly tuned turbo and aftermarket ECU, the engine can take a ton of boost, as shown.
That's right. 521 Wheel Horse Power with 26psi on stock internals and a stock engine. 100 octane fuel, and 44,000 miles on the engine.
There's another S2k pushing 575whp with a stock engine as well.
And before you go off about reliability, etc, from what i've read this guy drives his S2000 running about 18-20psi every day. And they have driven it on the road with 26psi running.
if any of you read my thread about all the crap honda does to the S2000 engine and how the thing is built, this kinda proves to what extent that engineering really goes.
asahi, do you hate me more now?

What size is the turbo also? That plays a big role in this.

Rep Power: 375 FYI, so far the guy has been driving the car at 18psi for a very hard 5,000 miles (in other words, beating the **** out of it) and they haven't had a single problem. They had to replace the stock clutch though, obviously, as it wasn't able to take the power. Otherwise it's a turbo kit with FMU, injectors, FMIC, etc. Stock internals, except a head gasket that drops compression to 9:1. They feel the engine should be able to take 600whp on stock internals.
so basically, cost of the car plus $6,000 turbo kit + aftermarket clutch = 521whp. woot.
For those that missed my thread on the S2k, the engine comes with a forged crank, forged rods, forged pistons, and a special head/valve train system with titanium valves and sintered/steel rockers, cams, followers, etc, all to withstand the rigors of 9000rpm and prevent valve float. A side effect of all that is obviously enough strength to take a massive amount of boost.

650cc injectors, stock plugs, FMU/VAFC, non-ball bearing GT35/61 t3/t4 turbo
i misquoted, as the guy with 575whp is running the aem ems aftermarket ecu/unit

Rep Power: 303 Oh hey doesn't the S2K have a fly by wire throttle set up? If that's the case, I thought the AEM EMS wouldn't work with a fly by wire setup? Correct me if I'm wrong.
BTW that's a very respectable setup especially with a t3/t4, but why did he go with a non-ball bearing? I'd expect a more responsive system with a ball bearing turbo...

Rep Power: 303 I'd like to see the fuel maps that they used with this setup. I wonder how the stock ECU responded when running with the VAFC on such high boost levels...

All I can say is....LIKE WHOA! Be interesting to see how the engine holds up over the next 1-2 years. Understand it is doin ok now, but a year or two down the line can be totally different.

Rep Power: 375 oh dont get me wrong, i'm sure it's putting more wear and tear than normal on the car. but keep in mind, the S2000 already has done to it what people would normally do to prepare a car for boost.
forged internals, titanium valves/springs, lightweight sintered steel valvetrain, ported and polished.

Rep Power: 375 one of the members is running 16psi daily. he has a similar t3/t4 garrett turbo, 650cc injectors, greddy e-manage piggyback ecu. stock ignition, stock headbolts, stock engine, save the 9:1 compression head gasket. from what i'm seeing he has 51,000 miles on the car, of which 34,000 of them are on 16psi daily, and he's pushed 22psi at the track.
no problems at all. not one. the only problem he had was something was the e-manage system didn't play nice for a bit with the larger injectors.
so far all signs point to the car being reliable in running high boost on an otherwise stock engine, save the fuel management an some type of ecu piggy back system (which most turbo kits come with anyways). that and the lower compression head gasket.

S2k what is it with you and this big head thing lately. As small as you are if your head gets any larger you just might tipover when you get up from the computer .
Oh well I guess that is what comes with the price tag the right to brag

Rep Power: 0 most NA performance engine you don't have to build up to get respectable numbers. Slap a turbo on, do all the proper tunning and bam... ISH LOAD OF POWER. It's just the lower engine (non-performance) that need to be built up to make that ISH LOAD OF POWER.
