What JRSC setup are you running?

I'm sure there are people out there who are great at those things. I figure if Subaru does it on their OEM cars then it provides at least some benefit. I figure anything that I can do to help cool the components back there will be beneficial. One question, where does the LHT radiator mount at? I'm kind of limited space wise because I'll have both A/C and power steering. Nice im doing the same thing full ac and ps setup. Whats your motor setup?

I don't actually have the car yet but will hopefully in a few weeks. I'll be using a stock GSR motor. Still trying to figure out the bolt ons (header, exhaust, and intake) plus I'll be using the Type R exhaust cam.

edit: I'm still trying to put together a list of everything I need. Is Hondata included in the JRSC Race System?

Also, from reading some of the setups here I may go with a Thermal 3" exhaust and the Kamikaze Header. Anyone know of anything better for the B18 motors?

Thanks,

I run a unported blower. I want to port it however I have yet to see a dyno of ported versus unported. What I believe (haters... this is just my own opinion) the ported blower's most significant attribute is it's effect on IATs. With that said, my IATs are fine. Porting "may" increase the blowers efficiency and Veris has some hardcore numbers to back it up. However I still state I have not seen a before and after blower port dyno chart on a B series JRSC setup.

I'm running 750cc RCs and an S300 with a 355 fuel pump. My regulator is set at 45psi. I just pulled up a WOT datalog and at 7300RPM my injectors were at 55% duty cycle.

[ekkilla23]

lets say someone just slaped a jrsc on a gsr without injectors wat should their fuel presure be set at??

p.s now i kno that no injectors are bad but im just wondering because my friend is doin this before gets tuned cuz he doesnt have all the money yet and he wants to try it out....if he dont have injectors the fuel presure has to be set high but how high?

You'd have to bench one, but I believe it'll flow a little more CFM at the limits. A minimal IAT difference caused by the lessening of the restriction at said CFM.

I'm not hating, but it will be really really loud. You can make very good power without going that big. Believe it or not, I made 300whp using a rage 4 to 1 header(2 1/2" collector) into a 2 1/2" resonator, then followed by a 2 1/4" thermal exhaust. No catalytic

Oh yeah, it was not a mild setup though. 15 psi Endyn blower on little over a 2.0 liter gsr.

Was your setup loud? I'd rather not have to listen to the drone of a fart can if I don't have to.

[JRSC•GSR•EG]

i just installed a new resonator and didn't notice any power loss but it did become a whole lot quieter

[sc4dr]

It wasn't bad. Got a little loud when the high cam came on(understandably). I miss the my supercharger I got my eye on Rogers setup though.....WOW!!!!

how much power do you think i would lose to something like a world sport exhaust?

[JRSC•GSR•EG]

http://videos.streetfire.net/video/E...ged_683554.htm

my dyno video, on the last run i made 232/172 i don't know why its not in the video but whatever...

i'm getting a new 4-1 header to replace the 4-2-1 header with a 2" collector i have now


mods:
94 gsr motor, mostly stock type r valve train and cams and port matched intake side, charger set at 11psi new SIR II b16 tranny -- hits 70mph in no time when getting on it

Probably not too much. IMO the key is to have large piping on the header, and no cat. Don't get me wrong, you will make more power with a bigger exhaust, but at the expense of noise. A couple horsepower loss if its a 2 1/4" system compared to 3".

[stmotorsports]

^^^ makes me lol @ all the idiot kids around here that see my setup & say shit like "man, you need to lose that [ac/ps/etc]..." or kids that think your exhaust needs to be as big as your wheels to make power

constantly. constantly. makes me noggin ache.

[nextproject97]

I definitely like my A/C in the summertime and am not about to take it off .My car is likely in the 12 s now with the current set up and I still have my a/c and p/s . I ran a 13.5 on street tires with a blower belt that was a bit loose loosing boost at high rpms that run .It was my first run down a track ever only week or so after getting the jrsc done and that was before the lht mods "header and intake" as well as upgrading the boost a bit and getting rid of the cat . I still have my a/c and can pull on many cars with jrsc hatch its putting down 260hp and 206 trq with ice cold a/c ! As well as a full interior , Sub box and cooler of sodas lol

Seriously, chill out.

I may stick with the WS2 exhaust. I have one on the GSR that I'm selling right now (2 door Black) and there's one on the car I may buy (4 door White, JDM front woop woop). I really like them a lot.

Noise and driveability is a big concern to me. I'm going to drive this from Urbana, Illinois to Pittsburgh, PA 3-5 times a year (8 hour drive) so I don't want to have to listen to a droning sound the entire time. Also, there's a reason why cars have power steering and that's because most people like it. I have a BMW 325iS without PS and it is miserable to drive at slower speeds.

So Kamikaze Header + World Sport 2 exhaust. What do you think for intake? I'm thinking something like the Comptech ice box.

[stmotorsports]

lol i wasnt talking about anyone on here, i said kids around here meaning this area. Noobs who dont know and think stripping a car out is the only hope to making it fast even if its your dd

no I just always seem to run into the same bunch of kids around here rocking gutted banged up shitwagon civics w nothing but some simple bolt-ons on the stock engine prolly making 104whp telling me how I need to do the same to my mint si. Don't get me wrong, I'm all for the grassroots thing and being a power junkie, there just comes a point where your dd riding like a stagecoach and sounding like a trombone section sitting in your back seat gets very very old.

you don't go stripping out a Bimmer or a Benz just to make it a tiny bit faster, yaknow?

lol that's a perfect description of what it sounds like

Yeah I'm going to shoot for power and crap like hood scoops don't matter to me because they don't affect my ability to enjoy the car. However, when I can't hear the music in my car or the passenger talking to me then is that extra 5hp really worth it? Is anyone going to want to ride with you?

As for some kind of tech. What are people running for LSDs? I was thinking about getting a Quaife but is the Type R another option?

[stmotorsports]

I'm running a DC2 ITR trans w GSR 5th and I love it, never had a prob. The diff is still tight after almost 4 years of street, autox and some track

[sc4dr]

you can find itr's a lot cheaper then a quaife, and will work great.

[hottcars1967]

i would say engine dampers and new mounts that way u could avoid having to install an LSD although i would reccomend the LSD along with mounts and dampers

I can't see how motor mounts and engine dampers would affect traction at all.

[hottcars1967]

well dampers will keep u from wheel hoping and mounts will support the engine way better then the stock mounts that would be more likely to crack it helped my traction on my 2006 RSX-S

[dundun]

gotta a funny noise coming from my JRSC sound like something loose inside the charger, almost sounds like some loose valve guides or something...do you guys think the charger is done with? thanks in advance

true that stiffer mounts and dampers help reduce wheel hop by maintaining correct driveline angles, although they are by no means a substitute for lsd. If anything they INCREASE the need for additional traction because the power that would normally be wasted in torquing (rotating) the engine in the mounts instead goes to the ground via the tires. Also the stiffer driveline mounting allows for less forgiveness putting the power down (ie- balancing clutch-throttle), so it actually makes it easier to spin the tires.
