its a L61

 

Nice. I always liked s2000's the most out of the little 2 seat coupes like the miata, solstice, sky cars. They feel so solid when you drive them compared to how you would think they'd drive.

 

here is the dyno, leaned out because the sniffer was way to far back so it read .5 afr the wideband was reading 12.4-12.5 under load

 

It's so much fun watching honda's go down..I took down an AP1 S2000 myself

 

I would be careful with those motors once you start getting ~250 wheel horse.

The Rods aren't very reliable beyond those power levels. I'd hate to see one of your blocks turned into swiss cheese.

Actually I lied, that would be pretty entertaining, but it'd suck to have to pay for something like that.

 

yes it would!!!! goin through somethin similar myself. luckily i just blew a hole through my piston and the block is salvageable. i'm not sure how strong your internals are but if your compression ratio is around 10.0:1 to 10.8:1 then 14psi should be your max! for my engine 11.5:1 ratio max should be 8-9psi but requires alot of fuel to keep it safe and never run less than 91octane.. 93 optimal for street setups.
