I cant not do stuff to my car, so I am looking at the JRSC setups. I really like to look at all the options before I sink money into my car and I have read tons of posts on here about doing a swap to something like a k20A2 or k20a type r, adding a turbo or a supercharger. Given their apparent amount of refinement and ease of installation, I think I am leaning towards the supercharger. I was already planning on I/H/E and a Hondata flash, but it looks like the JRSC street kit with I/H/E will make 174-185 whp if tuned right and the race version could make 220-225 whp.

However, almost everything has a downside (beside costs). I have not seen any posts about guys blowing up their heads or shooting rods throught the block running this setup, but surely there is something negative to be said...isnt there???? It seems like I could buy the parts for the racing setup for $4000-4500 depending on what I pick up new and whats used, which seems pretty good when going from 130 whp to 220 ish whp.

Let me know what you guys think, what am I missing that is a potential negative when compared to the other ways of increasing horsepower.

As a side note do any of you have experience running the race setup in a DD?

Thanks ahead of time and best wished for the new year!

 

I plan on getting the JRSC in time too on my base. Buddy of mine had a JRSC on his Ep before he wrecked it (AMF Racing). He orginally had I/H/E and reflash before he got the SC. Before putting the SC in though he had to reflash his ecu back to stock. So you could save yourself 600 bucks right there. Someone please correct me if im wrong about this.

 

I've had the JRSC "race version" on my car for a couple of months now, and the only downside I have run into is somewhat decreased fuel economy and increased tire wear. That may be due to my increasingly heavy right foot though

If you want to get the best power then make sure you get the programmable K-Pro, and not the reflash, and get your car tuned.

 

can you smog with race version i was looking at that one too...thnx

Did you put in the larger injectors when you put the SC on? Are you running the K-Pro? What kind of numbers are you putting up and did you do anything with the internals on the block or head?

Thanks

I put in RC440 cc injectors when I went with the smaller pulley. I already had K-Pro so I kept that of cours, and the block and head are stock. (this is in an EP3). I also have an AEM CAI, DC Sports shorty header, Random Tech High-Flow cat and Borla cat back.

Running the supplied program from Hondata I was putting down 194hp and 144 torque, but when I had it tuned it went up to 217hp and 174 torque.

NiPBoi, you won't be able to smog the race version in Cali, sorry.

That is what I am talking about!!!!!!!!!

I dont know what I would do if my Civic was making that kind of power, I may run out of things to tinker with.

Thanks for the info. I just cant find a downside to using this setup.

I know what you would do, the same thing I am doing, Having a blast.

Its not as much power as a lot of guys are getting with turbo's, but it is a ton of fun to drive.

Ya and I like the "linear" power band and I am not trying to win a dyno contest, just enjoy the car for all its worth. Besides I have to drive this car for years to come and would prefer not to anything that would result in bad news.

 

Is there a "downside" to running a supercharger on an ep3?
yes You can blow the **** out of your motor. Then you'll have an expensive car payment and a car you cant drive. If honda wanted them supercharged or turboed they'd sell them that way. spend the money building it n/a plus its a funner challenge.

JDM/NA/keep it clean

Ya, I have thought about that, but: I have been really looking around and I can find anyone blowing up engines running a well tuned setup, these engines are so "detuned" from the factory they can stand to make a little more power and it will take a LOT of work (or different engine) to make 220ish whp with NA and I just dont have the inclination or a shop I currently trust to do the swap of a k20a2 or type r or build a Frankenstien.

Lots of guys running lots of boost with limited downside and there are still guys with NA blowing up blocks and heads so I guess there is the potential for anything to happen, but if you are familiar with actual situations of a JRSC blowing up an engine please let me know.

Thanks

 

I have not ever heard of anybody blowing their K20A3 with a Jackson Racing S/C. That is one of the reasons I chose to go that route. Also you can get more power for less money with boost than you can with all motor. All motor is cool, but to me it isn't as cool as having a faster car for less money.

 

Downsides (that I've seen from other people who owned the s/c):
Isn't fast enough.
Might require a LSD/new clutch.
Isn't fast enough.

Some of the new tuning and fuel injector combos seem to really work well with the s/c, but keep in mind where you want to go with the car. If you want a straight line beast or just gobs of power, probably better off going turbo.

I dont mind the idea of a LSD, I figured if the car started making any real power it would need one. If this car ever gets into racing it will be roadracing style, so I am not really looking for a big dyno number or 12.0 quarter, although 13.???? would be nice. Really this will mostly just be a DD that I want to max out the "fun factor" and have great realiability and I think we all would agree that 200+ whp really starts to get into run.

This is exactly what I am thinking, biggest bang for the buck without blowing up the engine!!!!

with a 9.8:1 compression motor and a forged crank its kind of hard
