d.h., you said you have an S to, does his engine bay look like yours?

 

didn't know engine block has a vin.

 

yeah the block has a VIN on it.

you can check the VIN on the engine block too. if you look it up, it should have jhmap1 as the first part of the vin. i'm willing to bet it does. (jhm meaning japanese honda motor corp, since the engine/car is built in japan, and ap1 for the chassis code. no other engine except an S2k engine would have this on the vin on the engine)

also as stated, it's stamped on the block what the engine is. (f20c1 in your case)

but since your car is pulling much more dramatically than his, and you switched drivers, my next question is does either your car or his have aftermarket rims?

what mods does your car have and what mods does his car have?

if you're both similary modded or not-modded, and you both have stock rims, then i'd be concerned there could be a problem with the engine.

 

the b, d, and h series cannot be mounted in the s2000 as they spin the wrong way.

the only potential candidate is the k series. if his s2000 has a k20 in it, it is truly special. I have never heard of a K-powered S2000, though.

dh, there is no chance in hell that he has an engine other than the one that belongs in the S2000. to mount another engine requires that it be a K series AND have a custom bell housing to mount to the tranny, which by itself costs over a grand.

 

[quote name='revhi' date='Feb 23 2005, 01:04 AM'] I havent heard of any other engine that would fit in the car.

 

Just because one car is slower than the other doesn't mean the engine isn't a 'real' S2000 engine. There are a number of things that can make an engine underperform.

Could be a bad motor. Maybe you can have the dealership run a compression check on his engine ... that might be a good place to start.

Its more likely there's a problem with the car, than the car has a Honda Civic engine under the hood

Also you can try checking the airbox and making sure the filter isn't super dirty or clogged. You can try replacing the spark plugs, maybe some fuel injector cleaner ...

All simple stuff that could account for why your car pulls harder than his does.

It could also simply just be that your car is faster than his ... with any car, there are sometimes factory freaks that make more power than others.

 

You would know. It doesnt seem like a very diffucult thing.

 

I hoped you meant "F20x" stamped onto the engine. becaues if it's sticker, I don't know how reliable that is. Anybody can rip out a sticker and put it on something. I'm split down the middle on the rev. Correct me if I'm wrong. Doesn't B18x Type R engine rev close to 8.5k rpm. I push my s2000 to the limit before, and there's a computer shut off before you can hit 9k rpm. So at lest for me, it's kind of hard to tell. That's why I'm optimistic on that one.

Well, for one, he bought the car from a private party. Let's say that the engine is bad, what can you say? The guys is not about to return the money. But for a 02's to go bad, not likely unless the previous guy abuse the crap out of it. If he would of bought it from a Honda dealer, he wouldn't have to worry about that since certified Honda's have 100k warranty.

My last option is to bring it to the dealer. But I would like to find out at this community first, before having him spend $75 an hour to have someone to check it out. I think my best bet right now is to check for that engine stamp that you guys mention about.

 

the F20C is engraved I believe. If for some reason you can't find that, if you see the oil filter on the front passenger side of the block, it is probably the F20C (or a K20A, which is unlikely as that would cost thousands to do).

yes, the b18c5 revs to 8400 but IT CANNOT BE MOUNTED IN THE S2000; it spins the wrong way!

also, if your computer cuts you off before you hit 9000 in your car, YOU ARE ABUSING THE HELL OUT OF THE MOTOR. Don't expect your car to last. There is a "cold" rev limiter that will not allow the engine to rev to redline until it reaches its operating temperature.

If your friend's motor is truly too slow, have a compression test done. that is the ONLY way you will be able to tell. If the 4 values are pretty close, the motor is fine. Also, your car may be more powerful anyway; engines have a variance due to several factors. some S engines make 10+ HP more than others.

 

actually not....the rev limiter is there explictly to protect the car. Hitting it will not damage the car. It is designed to cut fuel LONG before any damage could potentially occur.
