Anyone experience any reliability problems with a supercharged S2k? My father is considering picking up a used 03 with a a comptech sc that has about 6k miles on it. The owner had professional work done.

Is this something we'll have to worry about in a 5k miles, 20k, other? Would it be smart to have it dyno tuned with a VAFC or other engine mngt system?

 

standalone EMS, the aem EMS, you will love it.

You should be fine, the SC kit out of the box works well and is reliable granted the owner didn't abuse the car.

 

I would check that it is the stock comptech kit without any changes (eg upgraded pullley). The stock kit seems to be very reliable from what I have seen mentioned on the forums.

Upgraded pulley means increased boost, and unless it is tuned properly there may be some problems.

Also some things to check may be the drivetrain, eg make sure the diff isn't broken etc.

 

Thanks... its the stock (5psi pulley i believe). The exhaust is stock and there's a comptech header also. Is a VAFC even worth it to have the car tuned slightly? I doubt my father would want to buy an AEM and spend all the time tuning...

To make the car as reliable as possible you should have the AEM EMS and get it tunned.

VAFC can only do so much.

Remember that once the standalone is installed and tunned you should never have to mess with it again, Unless you add or take away power items.

Good luck!

The SC kits, especially the votech's run pretty lean up top past 8400rpm

This is a different application, I know , but hopefully it will ease any concerns about forced induction reliability. My dad is into Import cars, and I am just now joining him, but on the other side I love full size 4x4 trucks. My turbo charged Diesel pick up has seen over 200,000 miles of hard abuse, which includes towing and driving in some harry off highway conditions and the turbo has held up just fine. I know that between the S2000 and my pick up that the RPMs are extremly different and the type of driving that will be done is equally as different; not to mention that one charger is a turbo and the other is a super, but anyway. Just trying to say that a forced induction unit can be extremly dependable if taken care of. Sorry for the semi-off topic ranting. The car will be fine

if the comparison was between 2 factory stock forced induction engines, that would be relevant but since the s2000 engine does not come supercharged or turbocharged from the factory it's a totally different comparison.

 

You're right. Sorry about that.

 

What is the weakest link in the S2000 motor in a turbo or supercharger application? How much horespower can the rods and sleeves handle before something starts to break?

Its amazing seeing that people can make 300+whp on stock internals and not run into problems whatsoever. The cylinder walls and rods are so thin .

The rods are forged, and don't need to be thick for the purposes honda built the engine. Reducing mass will increase reliability for an engine with a 9k redline. Engines built for boost are designed differently.

Keep in mind the s2000 engine is built with forged internals for reliability, not many mass produced engines have forged internals from the factory.

 

I have forged internals,

but that's probably from all the taco's at Super Antonitos

super antonitos carne asada burrito's ruled....now back to topic, one can conclude the SC kit out of the box works well on a daily driven s2000 that is not abused.

 

Don't worry about the internals. They are magnificent for a production car.

Your real worry with FI is detonation at high rpm. Engine management can control this.
