Supercharging the S

[Bonezz2k]

Hey guys I was wondering if i supercharge my S with like the comptech kit
or another one do i need to change any internals? and or how much can i boost before i need to ? what is recommended for a supercharger setup ?

[gomarlins3]

The CT and Vortech kits are designed as a bolt on kit. No changes need to be made to the internals of the engine. The FPR will be swapped out, the fuel pump will also be changed aas well as the crank pulley. Everything else just bolts on. There is an engine management system that plugs into the OEM ECU and that's about it. The install can be done over a weekend by someone that is good with tools, or in a day or so by a professional. I had mine done by a shop that specializes in Hondas and am very happy. They are happy with it as well.

[karnito]

which one do you have marlins?

[gomarlins3]

I went with the Comptech system since they specialize in Hondas. Nothing wrong with the Vortech system though.

[karnito]

I like the comptech system myself. I think the comptech have made a better product.

The two are so close, the arguments go back and forth all day long.

The Vortech supposedly makes a little more boost, comes with the aftercooler stock rather than as an add-on and requires drilling a hole in the oil pan for the oil return line. They are both centrifugal units so they don't produce any gain at low RPM... something that hasn't been lost on the S2000 community.

If I had the option, I would have gone with a positive displacement SC rather than the Comptech to give the car more low end. Comptech makes one for the NSX and TSX. However, last I checked the positive displacement blower is still not a reality for the S, although there were some threads on S2ki.com about various setups in development.

Now that I have the CT, do I regret it? No way. It was and still is worth every penny. In answer to the original post, nothing else needs to be done to the car internally to run either stock kit. Some things that are probably wise, however:
1. Dyno car after install and get a a/f ratio accross the rev range, make sure it's making boost etc.
2. One step colder plugs, word on the street is that the iridium ones are NOT a good idea with the SC as some folks have had problems
3. Highest octane fuel you can get
4. Keep up with your oil changes
5. For peace of mind, you could consider putting in a wideband A/F guage

If you decide to upgrade something in your drivetrain, keep in mind that you will create a NEW weak link.

Thanks guys lots of good Info

Ok. I like the CF filter cover from comptech.

I appreciate all the info on supercharging! I have thought about bolting a system onto my 03. I love power and can't imagine having an extra 100 hp. FYI, this month's issue of Hondatuning page 72-76 is part 2 of their project bolting on a Vortech. Can anyone describe to me what its like driving the car aggressively with a SC? I recently drove a Lightning with some mods on the SC and it was the fastest truck I have ever driven, it was a rocket! Does the SC really transform the S2K compared with normally aspirated??

[abe_fshr]

does anybody know if you can install aftermaket performance parts for 04-present S2K's? (superchargers).....i see alot of parts out there for 00-03, but not so many for the s2k's equipped with the F22C1 engine, i read somwhere that the newer block is longer than older engine, and that the newer engine have the same intake and exhaust as the older engine, im not sure if that is true either

thanks

[Bonezz2k]

There are superchargers for all the models. here is a link to Comptech systems:

thanks for the help

HI all. I just joined the site today. I have a 04 sc (comptech) s2k with 28K miles on it. I have had no problems with it and it is quite faster than the na s2k engine. I believe the sc system along with the additional mods as described later has provided more torgue at 3-4K rpm range. Since I live in a desert climate, I elected to also install a comptech aftercooler. The final mods I chose to install include comptech headers, catalytic high flow converter, and a new AEM EMS unit. I am still confused whether the expenses associated with performance cat exhaust are worth the couple of extra horsepower in light of the price involved. Having a professional tuner has made this car flat out move. I would make these mods again in a heart beat.

Good luck with your decisions. Although s2k's are way fun to drive as a stock unit, they become much quicker and more fun with F/I. Since the red line is lower than the earlier models, it took me a little practice to learm when to quick shift before the rev limiter would kick in after installing the sc.

The comptech supercharger only really *starts* to provide more torque around 3K. Closer to redline it produces a LOT more torque.
A dynochart from Comptech can be found here http://www.comptechusa.com/store/med...percharger.pdf

does anybody know the max hp sombody got out of an S2000 with forced induction with the original engine?

thanks

[AGBLLET]

Abe, I have a couple of friends that are running 310 and 320 respectively with superchargers, aftercoolers and some type of ems expermental unit that I do not recall the name of. They are quite happpy with the results. I am right in the middle of installing an intercooler, headers and exhaust, larger catalytic flow thru unit and will be using the AEM ECU unit for engine and fuel management control. I currently do not know what size pulleys are currently on my supercharger, nor do I know the size of the injectors. I am going to leave those decisions up to my tuner after we complete a few more installations. Anyway, it is our colletive belief that with the correct tuning, we hope to obain a highr horsepower figure closer to 340 -350. Naturally, that is just a guess at this time. I can provide you with the results after we complete the tuning and dyno tests in a few more weeks. In terms of turbo power, I believe that you are able to secure significantly higher horsepower amounts but I have no experience in that area. I am sure that some of the members with turbo systems can provide you with a more informed answer.

Take care,

[abe_fshr]

thanks...but have you heard of an S2000 beating a ferrari?

[AGBLLET]

No buddy, i have not. But I believe such an event could likely occur in that many vintage ferrari's are not as powerful as the stock s2k not to mention the modified ones. In my humble opinion, I believe that many models of loder ferrari like the 236 for example would have a very hard time beating our s2k's both in a straight line and over a race course. Do I think modern day ferrari's would kick our ass, hell yes. So what. our cars cost 1/10th of what they cost. Hey, the rich people should be entitled to purchase stock sports cars that have beteen 600 and 700 horsepower and receive as many speeding tickets as they want. If your desire is to beat modern ferrari's in any form of competition, then you should have never bought an s2k. Good luck in your endeavors bud!
