I really counld use some help from the ITR gurus. I want to purchase an JRSC for my ITR. I am confused on which JRSC will fit the ITR.

I have heard that the B16a2 (99 SI) will fit. But some have said that will fit the GSR. Also heard that the GSR will not fit because of the manifold bolt pattern is different.

When I looked at www.supercharger.com and under the high boost section, the part number 989-604 applies to the ITR, however from what I can remember there was a regular boost version too, I just dont recall that part number

I just want to get the information straight before I start looking.

Thank you

Can't you still buy them, brand new, specifically for the ITR application? If so, call the retailer and just ask.

 

there is a itr spec model

http://www.supercharger.com/Shop/Vie...eIndexID=38961


but model for a civic si B16 head will work

they do sell upgrade pulleys for the SC as well, search and look it all up. there is a lot on info on this site about JRSC's

 

See that one is the high boost version not the CARB legal one. I was looking for the CARB version or one that can be interchangable. So I guess the B16a2 (Civic SI) version will work.

Thanks

 

Why don't you just call and ask instead of guessing? Not a lot of us here have bought a supercharger in the last 5 years. Mainly because it works so much better on the GSR than it does the ITR.

 

I called them but they were pushing the high boost package.they were back to not sure and would get back to me about the civic si fitting the itr

 

The only difference in the two kits is the manifolds. GSR is the odd ball and the B16/ITR kits are the same except the ITR kit has a different alternator pulley.

 

Of course they were. Aren't they like $1500 more? I gotta think the normal package is still being offered, but then again the normal package didn't make a lot of extra HP on the ITR, either.

You can do a set of mild cams and with good tuning you'll be in the mid-190's while keeping the nature of the motor intact.

Otherwise the normal JRSC boost package will maybe give you a few more HP, but it'll add a lot of heat and an extra 35lbs or so of hardware.

 

My itr made 238whp and 194ft/tq. @7psi...a set of mild cams and good tuning on a stock ITR motor wont get you those numbers. I am thinking about selling the kit though and keeping my s300 for possible future built N/A or turbo build down the road. Oh yea my ITR also still has the a/c and p/s which is even further less likely N/A

 

See these are the kind of numbers I am looking for. I truly do not want to mess with the internals. This is partly my daily driver and also track car. I rather slap something on and keep it legal w/ a CARB supercharger kit.

 

you can use the b16 model or the itr model. the gsr manifold does have a different bolt pattern but have seen people use the gsr manifold on a type r. all you have to do is get a intake manifold gasket for a itr and mark the holes that need to be drilled on the gsr manifold.

 

There is absolutely no way the standard JRSC kit is going to get you anywhere close to 238hp as-is.

Chances are turbojdmhatch has ~$5K into his setup with tuning and dyno time.

My point is that the normal off-the-shelf standard kit will net you about the same HP as an ITR motor with mild cams, I/H/E and tuning (I've seen the dyno sheets on the same dyno on the same day). And there will be no worries about track issues with minor bolt-ons.

If you want to go faster on the track, upgrade your suspension and tires instead.

 

fixed

 

You know, back in the day we used to preach that so much on here that I stopped including it in my posts. With all of the n00bs, I should start harping on it again.

There is nothing more satisfying then hearing someone complain about how slow their car is at an autox, then going out in the same car and beating that person's best time by 3+ seconds. It really opens their eyes up.

As far as HPDE's, who really cares how fast your lap is as long as you are learning and having fun. It's not supposed to be timed anyways.

 

Well first of all, my ITR was in a bad car accident less than a month ago, so I am rebuilding her. This is the reason why I am wanting a JRSC.

I already have pretty good tires and suspension set up. Running Khumho XS with Tein RS along with front and rear sway bars and strut bars. Car has already been corner weighed and aligned with mild autocross set-up

Car already has I/H/E. Though the header will most likely be replaced since its damaged on the bottom.

I just want the JRSC for pure fun. I have a 95 Accord w/ a H22 Type S, so I already have a decent NA car. I had a turbo Miata before and now I want to just try a supercharger.

 

It is your car and you should get what you want, but honestly don't expect too much from the standard JRSC ITR kit. The potential is there, but you're going to have to throw more mods at it to get HP levels over 200.

If you're willing to spend ~$2800 for some extra torque and about 20-25 more hp, then you should be satisfied. And don't forget to re-adjust your suspension as the kit does add weight.

 

Such as what?

I actually had the car dyno'ed about 2 months ago on a Dynajet and pulled 161hp. The low number is due to the damage on the header caused by the previous owners.

These are what I was going to run with the JRSC

-4.0 charger pulley for 11psi with stock crank pulley

OR

-Crv crank pulley B20 14psi

 

It does not look like they sell the carb legal supercharger kit for the Type r or Gsr aymore. It is no longer listed on supercharger.com
Just call them and they should be able to tell you if the civic si kit will work, they do still sell that one

 

It appears that both the ITR and SI high boost systems have the same product number, therefore the CARB legal version should be the same too.

 

Actually, the JRSC for ITR comes with a 4.2 nose pulley and puts out about 5.5psi.

I'm running it with the MVM stepper pulley, which is supposed to give you approximately 7.5psi, but i'm putting out 8.5-9psi

The CRV crank may get you over 10psi though. The only way to stay carb legal is to keep the JRSC FMU and relay setup at 5.5psi.

 

And at 5.5 psi what is an individual making?

I just want to be CARB legal at time of smog

 

I don't know about on the carb stuff, but people usually average/top out at around 220whp with good bolt ons. That number may be with better fuel components and engine management.

 

check my thread. it shows progression from stock to upgrading pulleys slowly.

hope that helps and answers some power numbers for you.

 

Does anyone have experience with the LHT intercooler for the JRSC?

 

No personal experience but I've seen them in person. It's top notch quality and it does work but a bit pricey.
