Some supercharger kits usually the cheaper ones kreftwerks say you need to remove the ac compressor to install the kit. I can't find anywhere in the description of the CT Engineering Supercharger Kit for the 05 rsx type s needing to remove the ac compressor. Yes it's 4k for the reflashed ecu and stuff (though my second question is this extra 500 compared to 3500 worth getting the reflashed ecu pretuned for the supercharger kit worth the 4k?) But is it safe to assume this kit allows you to keep your ac compressor on?

Expensive with reflashed ecu by hondata $4k -

The CT kit is eh IMO. it does let you keep ac due to how the sc mounts but due to no provisions for an intercooler you really will only get 40-50hp out of the base kit. You could get closer to 275-300 but it would require serious work like porting the supercharger, s tube, and supercharger intake manifold, as well as the cylinder head, a good set of cams, header, exhaust, etc. It would also require a custom fabricated intercooler or water/methanol to keep the IATs down.

Also the base kit to which you've linked us doesn't have any Hondata tuning (it's an error on their part) it only includes a piggyback to add fuel, lower vtec, and clamp the map voltage so the stock ecu doesn't flip out... it doesn't do anything to alter timing either, so it's basically like a fancy, modern, electronic FMU/missing link. The kit option that does step up to the kpro is 5k... which is a lot of money for not a lot of gain.

You could spend the same amount of money and build a badass NA K20 and make 300hp lol

The KraftWerks kit is the way to go if you want to make decent power now or in the future. None of their kits come with piping or FMIC but the kit is designed to use one, especially if you want to make more power, to keep IATs down. I've seen a few KW cars with a KW branded FMIC, I'm not sure if it's an option they offer (I think it is) or if people merely stenciled the name on but I've seen 3 cars with the exact same logo on the fmic.

There's a guy down the street from me who has the KW race kit on a 13 4dr Si with the fmic i was talking about. I don't know the exact power output but it sounds great and hauls serious ***. There was also a sleeper s2000 at Road Atlanta a few weeks ago, 100% stock exterior, not even an exhaust, but it had the KW race kit and FMIC on it (super sneaky, I think he plays dirty lol) and it was seriously fast around the track.

Honestly I think that anyway you cut it the KraftWerks kit is the best bang for the buck, especially when you consider the power potential compared to the CT kit, which costs considerably more. The 900 dollar gap between the KraftWerks race kit and the base CT kit would get you the fmic, charge piping, intake piping, bov, and part of the fuel system for the KW kit.

It's really up to you, though you need to decide on what you're looking to do.

Do you want your DD to have a little more "pep" and be more fun to drive? If so the CT kit would probably be better

Do you want to have a DD or a car that makes decent power that's still fun to drive with the ability to make more in the future? If so then hands down the KraftWerks kit is what you need.

While you do have to eliminate ac, depending on where you live it's doable, hell I live in GA and most of my cars don't have ac and the ones that do I never use it lol. If you wanted to keep ac bad enough then you could always convert to an electric motor driven ac compressor, just something to consider.

 

With a 5 month old son who will ride in my DD car i have to keep my a/c. So would I be better doing skunk2 mani, skunk2 cam gears, skunk2 tuner stage 2 camshafts, skunk2 valve spring retainer alpha kit etc instead of going the supercharger kit route? So with the CT I don't need to have an intercooler? Or is it a custom must..am I better off spending the 3500 and buying Kpro ecu from hamotorsports.com? I'm looking to achieve between 250-300 whp. What's my best route? Thanks again I really found your post to be an eye opener.

 

I strongly feel the kraftwerks/Rotrex supercharger is superior to the roots blower however if A/C is a deal breaker for you then I would suggest considering a small turbo kit. The power delivery and torque curve of a small turbo will/can be similar to a centrifugal supercharger.

 

It sounds like you would be better off with a k24 swap.

 

Look up TTS performance I believe they sell modded Kraftwerks kits to fit RSX's so you can retain AC.

 

Thx guys!

 

yeah, lots of good alternative options here that are better than the supercharger.


bolt ons and cams/tune would be great for more pep. low boost turbo would be great for more tq and a bit more speed.

k24 swap would be great all around, idk how much of a mpg hit you would take since its your daily.
