I was wanting some input on the SC. I know some one on here had one and hated it, so they went turbo. What is your over all impression. Does it make the car more fun to drive???? Do you lose the Vtec cross over???? How much boost can you run on stock internals??? What do you need to buy that is not included in the kit??? What kind of intercooler is available?????? HP????

Thanks in advance....

 

 

Mike Marssey (sp?) (Rboosted717) will be able to answer most of your questions on that. He has been pretty successful with his JRSC setup, one of the only ones I have seen with that much success.
As for the IC, the JRSC unit is not configured to run with an IC, rather it relies on water injection to cool the intake charge, and/or a Hondata intake manifold gasket...
As for additional parts, I think a larger injector is needed (370-440), while this may be argued, the larger injector allows you to not require so much pressure from your fuel pump...

Thank you

 

keep the knock levels down and boost the ***** out of it........i've seen 13 pounds on a stock C1 with only a cheap block guard.....still running after 2 years, fast as *****!!

they NEED tunning to be strong

 

Does it make the car more fun to drive????

Yes. It's faster in any rpm and any gear. Sounds pretty cool too.

Do you lose the Vtec cross over????

Nope, you can still hear it and feel it. On other Hondas it seems to mask it some but the ITRs crossover is so aggresive that you still get it.

How much boost can you run on stock internals???

I know people on 10, but I wouldn't recomend going over 8 with good tuning.

What do you need to buy that is not included in the kit???

A lot of stuff. VAFC to tune the fuel, MAP controller to fight detonation and high rpm fuel dump, BTC or a J&S safegaurd to protect your motor, better fuel pump, bolt ons. If you go with more boost than 5.5psi you should get injectors and some sort of standalone.

What kind of intercooler is available??????

No intercooler as of yet. Maybe in the future but I'm not holding my breath.

HP????

Less than advertised. Properly tuned you can expect 195-200 at the wheels with bolt ons. The good news is the area under the curve, more average torque and hp across the entire rpm range than just about any mod I can think of (short of spending 10 grand on a crazy all motor setup). I'm getting more torque to the ground at every rpm point than the engines peak output at the crank when stock.

 

Screw the FI, and go completly NA. I had the JRSC on my car, and I had it removed. I'm much more satified with my NA motor now.

 

Unless it's a GSR. I hear it's pretty good on a GSR

-Aoib0t, who corntemplates.

 

just not AS difficult.

 

----What is your over all impression.
My over all impression is that its a good mild kit for those who just want some more power without doing anything too crazy. However to make it work correctly I would recommend a Hondata and RC injector based (stand-alone) setup which will allow you to fully tune the car to your mods.
----Does it make the car more fun to drive????
If its tuned right yeah its tons of fun. It really wakes up the car and makes it a lot stronger without the need to downshift as much. However downshifting with it is even more fun!
---- Do you lose the Vtec cross over????
With a stock JRSC setup, yeah you do lose the VTEC kick in sound. Its bairly noticable. Even with a Hondata based setup its still really hard to notice. However if you add on a good exhaust system (header, high-flow cat/test pipe, and a exhaust) you will notice it more and hear it more. Also if you up the boost with a pulley you start to notice even more of a VTEC kick in. Heck look at my car. I get a 80whp jump in power and a 60lb trq kick when VTEC kicks in at the stock point. And thats with stock internals, tons of tuning, and around 10psi of boost with a good, loud exhaust.
----How much boost can you run on stock internals???
It all depends on how you tune the car and how long and how much load you want to put on the engine. With the right amount of good tuning with the correct items you can run at high as 10psi like I have. However I also only have 21,000 miles on my car with a 8,000miles per year average on my car. However those are all hard miles. To keep it relitavity streetable, without going to extream on the exhaust stuff, etc... I wouldn't go above 7psi which is what the GSR's can do stock. With our compression, etc... you really have to tune these cars. Type R engine's leave no real "playing" room with tuning. You basically have to out tune the Honda people who made these engine work so well to get more from them. Also with our engine's setup, they really don't errors in tuning, etc... Our engine's are made and designed with almost perfect tuning with little room for error. This is why tuning JRSC cars can be difficult. However with a Hondata and a dyno and a good tuner, its fairly easy to get 190-205whp from a stock JRSC R with a Hondata and injectors.
----What do you need to buy that is not included in the kit???
I would get ahold of a good local tuner with a Hondata setup or call places like(www.dynospotracing.com) and get a Hondata setup for your car.
Also a intake helps some as with a good exhaust system. If you want a good strong setup try: JRSC, intake (comptech, JR), header (Kamakaze, Hitech), cat/or test pipe, and exhaust (thermal, any 2.5" or 3").
----What kind of intercooler is available??????
No real intercooler is on the market yet. Jackson Racing as well as some euro companies offer a liquid intercooler for the JRSC, however I would stay away from it. I have done fine without it. Getting a Hondata intake manafold gasket is a killer mod to put on before the blower goes on to help with cooling. However their is a guy who as we speak is having a intercooler made for his JRSC GSR by Dave Bell Eng. They are in the building and testing phases so stay tuned on the results on that issue!
----HP????
stock R 155-165whp
stock R with just a JRSC 180-190whp
R with a JRSC, Hondata, injectors, intake 190-215whp

Hope that helps some.

You should visit http://www.hostboard.com/cgi-bin/for...r=40&SUBMIT=Go if you want more info on the JRSC. Very informative board.

I have a GS-R so everything I have to say might not necessarily apply...

More fun to drive? Most definitely. You definitely can't argue with instantaneous boost. More torque down low, and you maintain the table-top flat torque curve.

Lose Vtec? Well... VTEC crossover was never that pronounced to begin with. So... not really sure about that one.

How much boost? There are plenty of people boosting 9 pounds on stock internals. At those boost levels you'll probably want to upgrade your fuel delivery (to be safe). There are a good number of people boosting 9 pounds with stock injectors and the JR FMU (5:1 rise rate) with a high pressure fuel pump, but those people are seeing about 100psi fuel pressures. You'll need larger injectors and an adjustable FMU to be safe.

What do you need? You need a high pressure/flow fuel pump for sure. Get the GSS-342. Don't even bother with the GSS-317... unless you want to buy mine... hahaha. I'm going to replace mine with a GSS-342 when I put that 9psi pulley on there. Some sort of boost timing controller would be good (retarding your ignition timing will cause you to run hotter, and your car will most likely bog at low rpms). J&S safeguard isn't a must... but it's probably a good idea. As for fuel control/MAP mod... Zip on the board I mention above has created a box that will control your vtec point, the MAP mod, and the IAT mod. You can also add a boost controller to that box so you can limit the amount of boost you're making.

Intercooler doesn't exist yet. But there are a few people who are trying to make one.

HP? On an ITR, I hear it's less than advertised with the stock kit. But I'm pretty sure if you can tune your fuel right (use Zip's box to prevent from running way rich at high rpms) you'll end up with over 200whp.

If you have any other JRSC related questions... feel free to ask me or go post on that other board.

Just get a Hondata and have it tuned with some 440cc injectors. By doing this you can remove all the jumper systems, add-on systems, and all the little devices to band-aid the problem. Personally I found it easier to just grab it by the roots (no pun on the blower) and just fix the problem with a stand-alone. Zip's setup rocks, however if you can get access to a Hondata setup and a good tuner or a pre-tuned setup then I would just do that.
Also when running more boost you don't need a huge fuel pump. The only time you need a fat fuel pump is when you run high fuel pressures. However with more boost the tip-in detionation will be stronger so you will end up wanting larger injectors to fix that since the fuel will flow faster to stop the tip-in.
With large injectors, having a high fuel pressure is not needed so having a huge fuel pump is therefore not needed. I use to have a HUGE external Bosche/Endyn fuel pump when I was doing like 100+psi with 8psi and stock injectors and a cartech FPR. However I was still getting that tip-in detionation. So I just got a stand-alone setup with 440cc injectors, put back my stock type R fuel pump (yeah not even the JR one, the honda one is fine), got rid of the cartech and just ran stock pump to the stock FPR to my large 440cc injectors and everything works perfect.
But yeah hostboard is a killer place to get info also. As with the fellow H-T FI board. The type R board is also a good place for most any question because we have all types of people on here that can help out with various opinions and idea's, etc...

Yeah.. what he said. Hahaha.

He's right though... hondata is probably a lot better than the bandaids that I'm using.

 

If you would like my opinion SC's suck.......

if you want more power get turbo

 

it really depends on what you want to do w/ your car. Daily driver, autoX, road race, etc.

 

Spoken like a true H-T.com FI board member. Hahahaha.

He has a point though. If you want more power... get a turbo. If you want a table top smooth torque curve and instantaneous boost, with lower peak numbers, get the SC.

turbo's are cool if your into draggin and/or straight line stuff. However you really don't need that much power. People now adays are really way to power hungry. Heck with 265whp and 170trq that I have I lose traction in 1-2nd gear with using R compound tires!!! Also when I downshift on the hwy I sometimes slip the tires!
Having 300-400whp and 200-400trq will be crazy! I have ridden in many turbo tegs and civics with anywhere from 300-500whp and they all loose tracting when getting on it! Having to feather the gas all the time sucks! Front wheel cars are just not ment for that much power.
However if you do a turbo kit with a small turbo and setup with puts out like 300-350whp that would be awesome because your right on the verge of too much power and not enough power.
I think that on a JRSC car the limit for driveablilty is around 275whp. Even now when I go to take off in traffic or I need to get around someone I normally just spin the tires and make tons of noise which sucks. I'd rather just grip and get outa their. You can make big power cars work on the street however, having that much power still can only really be used for dragging and top speed driving otherwise you will just over power the car in everything.

 

What about reliability on a road course? I've considered a SC, but wonder how reliable they are for 20+ minute lapping sessions. What kinda of precautions would need to be taken to ensure trouble-free driving?

 

Well, I had the JRSC until my engine goes kaboom and it was time for new pistons. I lowered the cr to 9:1 and thought myself now it is time for a turbo, cause the JRSC can not deliver enough boost, but the engine can handle more with that cr.

A all out kick *** JRSC setup cost about the same like a kick azz turbo setup.

There is the JRSC and the turbo kit which are about the same.
You need standalone, injectors, clutch, fpr, fuel pump, exhaust.
On the JRSC setup you need a header. On the turbo setup you may need some electronic boost controler.
Lower cr pistons are required when you want to boost more than 8psi safe on a long periode (and daily driver) on the stock bottom end. Valvesprings and rods are required when you want to rev higher for long periods.

So it costs about the same. Either turbo or SC

The 1st big PLUS of turbo is, that it will give you more power with less stress to the engine when boosting more than 7psi, cause the air can be intercooled with a turbo setup. And the 2nd big PLUS of the turbo is, that you can adjust the power with a boost controler.

I was soooo angry, when I saw the charge air-temp of the JRSC. 170+ Deg. Farenheit on 8psi. It is only about the half of an turboed intercooled engine.

When I had to do it all over again, I would go turbo 100%.

I don´t understand the discussions on to much power. You can adjust it with some controler and nobody can have too much of it. When you spin the tires all the time with 1 Bar boost, than the heck screw the boost lower to 0,6 Bar.

 

what about the lag?

-Aoib0t, who dun know about Turbo t00 much

 

what about it?.....turbo lag is only there first gear basicly and with the T3/4 turbo there is hardly any turbo lag at all......

 

cause like if you use it for autoX when starting out, I wonder what the turbo lag effects are. Although I guess they are used in Drag racing as well so I guess that doesn't matter. I dunno. I was told by others that Turbos get laggy sometimes depending how the car is set up.

-Aoib0t, who is curious about Turbos

 

Im going with the JRSC on my GSR. But not for a few years yet.

 

ALL SSB GSR's must be Super Charged by a couple of years
