Default SuperCharging?

Everyone is into Turbo Charging their 2.5 RS making it a RS-T. What about supercharging kits for the RS? Are there anykind of bolt on kits available for a MY98 2.5 RS? I was looking into putting more power in my car and I just wanted to explore every option possible. Does anyone have a supercharger in their car? If so is it better or worse than a turbo kit? Where can I locate a supercharger kit? If possible please post pics and specs. Thanks.

Rimmer is the only one that actually makes one for us. I think if you do enough research, you'll find that turbos are just plain better.

Thumbs down

Rimmer is the only company, currently, that offers a supercharger kit for the RS. I dont think it is 100% bolt-on however. Most people have gone through and modified it further. JC Sports just introduced an SC kit, but they do not have any pictures or even a unique description. Current opinion from the board is that this SC kit is the Rimmer kit being redistributed. I think TRI Tuning was hinting about some SC project, but to my knowledge it never materialized.

There have been two versions of the Rimmer kit: a top mount eaton blower, and a sidwinder roots-type kit. 5252 has the top mount system, and ARG (Al Gainey) has the sidewinder kit.

If you watch the classifieds, you may be able to locate a used SC kit, and it is probably the best way to go about purchasing it. The customer service of both JC Sports and Rimmer seems to be flakey, so be cautious.

If somebody is asking about aftermarket SC options, I really don't think it is necessary to dictate your own personal opinions upon them regarding turbos.

Ok we all know that rimmer made chargers before, but they tended to blow up your engine. in fact most of the engines saw the wayside. something in their design. flaw.. They changed their name to RPS, rimmer performance systems Inc. then after all of that rimmer decided to sit down and make a real charger that was pefectly safe. its not called the side winder or the top mount, all of those were from rimmers old design and if you latch on to one i would be careful, they arent safe for your engine.
After many moons of research rimmer has only came up with a charger for 99 and up RS. no 98... only for the SOHC engine. But it comes in two styles its an autorotor design with either a top mount intercooler or a water/Air laminova intercooler. The systems yeild 230 hp. but no luck with a DOHC. http://www.rimmersuperchargers.com/superchargers.html

good hunting

It would seem to me that a Vortech SC on an RS should be an easy do, but of course a Vortech is centrifugal and similar in response to a turbo. I mean, all you need is a bracket, a pulley and belt, oil and water feed/return, and compressor to intake piping. And of course the unit itself. And then handle fuel the same way turbo applications work.

Superchargers do work on Subaru's and work well. The problem is finding someone who can design and build a good kit.

I live very close to Rancho Cucamonga, California. This city is home to Kenny Bell Superchargers. I went there with my RS and showed it to Mr. Bell. He took some pictures of it and stated that the Rimmer kit was incomplete and not engineered very well. He said that "you can't just throw a supercharger on a car and drive it". I ask him about making a kit for the RS. He stated that is wasn't worth it to do the R&D and only sell three kits.

That IS the problem. No one is willing to develope a good kit if there is no large market. For Kenny Bell, he sells hundreds of kits to large V8 SUV's and PU trucks. A lot of his systems are going to Japan!! The Japanese love those big-a$$ American trucks. There is a tremendous market for supercharged trucks but not Subarus.

Mr. Bell stated that he would consider doing a complete kit if he had 100 orders. Paid for in full.

There you go. End of story.

Jackson Racing should make a supercharger for the RS. In my opinion they make good superchargers but the SC doesn't have good top end on a high reving engine but for the RS it would be good.
