Going by the temps I seen I would with an sc on a track but not road, an na s2000 does not need one, a turbo from what I've read does.

 

That's just your heavy foot and 15 speed gearbox!

Nut, this was the worry about the OP. The natural reaction for most people reading this is now going to be 'oh I have a decat / intake and I need a remap'

Not true. A decat on a standard car will net a few bhp, and what this equates to in terms of afr is really small, maybe half a point at most.

Yes you can if you want to squeeze power and make the most of the modification but you don't need it to make your car safe. The oem fuel map had a lot of margin, like most. Our cars have forged pistons too. If you really want to be sure, get a dyno done and look at the AFR plot. The AEM does make a couple of little resonance bumps low down but this is a function of the length.

You MY car cannot be remapped, you would need a different ecu or piggyback.

In your case the car will if anything use LESS fuel running an AEM, not more.

Did you get the 'temps not endorsed by the factories' bit. 137 deg is still damned hot, running cooler if you got the chance is a no brainer.

 

Thats an evo not an S2000 and i think they have an oil cooler as standard, plus its not a boosted S.

The temps I've seen on a boosted S are good enough fro me regardless of what anyone says.

 

you'r your own man do what you want.

 

Thermo-Dynamics and Entropy. Only ever consider my car in such physical terms when chasing the photons coming out of the headlights!

 

My own consideration when building/modifying my car was to do everything possible to get rid of heat.With that in mind I have a fullblown triple core rad a 19 row oil cooler with separate oilstat.1 kenlow 2 speed fan (I would have fitted 2 if I'd got the room)plus a slimline fan of unknown origin, a custom made rad shroud, a cold air intake on the front bumper and a ducted cooling plate plus a vented bonnet.

To say I'm paranoid about excessive heat is an understatement. So I would have to agree with Richard about the cooling mods, after all its got to be better than frying your oil.Excessive heat is a killer, but then I would sooner have a car that can cope with heat rather than the other way around.

 

IIRC t here are some well written articles that explain why it's equally bad to have oil that never gets as hot as it should do.

For all of the above, you'd be better off teaching people how to change gear so they don't over rev the engine and stuff it that way.

 

I know for a fact that a track day doesn't cook the oil in an S2000. Even the oil out of MB's race car looks fine after several races.
