Hey guys I’m new to the site and have a 1998 ITR and was thinking about safely boosting it. I was planning on only going no more than 6-7 pounds of boost b/c of the high compression. I was looking at some super chargers like Jackson racing, pro charger or Vortech. I wanted to get your opinions about which one to get? Any info would be appreciated...Thanks

 

The Jackson racing is tried and true. I good friend of mine works at Procharger. I got see first hand their kit on the Civic. It is a nice system and I like the fact that it has an intercooler. They also include a washer fluid resevoir b/c it will need to be relocated. That is about as much insight as I have, sorry.

 

thanks for the info.. looks like the jrsc is less complicated system as well..

 

The JRSC set-up is decent with some limitations. What are your goals?

 

The Jackson will make more low end grunt, but it will poop out on the top end. The Vortech will make nothing down low, but will scream at the top end. Just remember that for superchargers, a centrifugal (Vortech, ProCharger, etc.) will make more power top end, and that the roots/positive displacement superchargers (JRSC, etc.) will make constant boost at any rpm but will get eclipsed by the centrifugals up top.

And definitely get the intercooler option whichever kit you choose.

 

JRSC + Hondata ECU + tuning=

I can't wait to get that stuff back in my car - it was so fun!

 

thanks for all the feedback guys...

i was only looking to get maybe 240-260 whp.. safely... nothing over the top..

is that the case at 8400 rpms? when would you say it drops out. this dyno seems pretty good up top with the JRSC, do you have any Pro Chargers to compare to?



unfortunately i dont know what kinda boost that is... im assuming 6-7psi.

 

the kit as a pain to put on with the motor in the car

indeed



had to install other things as well. thats why i pulled it.

 

Honestly, IMO if you are going to go with a centrigual blower, you will be better off with a turbo. same type of compression, and a 4 cylinder that doesn't have much torque to begin with is not going to like having to drive a blower too, that doesn't even make good power until you spin it up.

A roots blower, on the other hand... if you want supercharger, the jackson racing kit is the way to go. feels like you threw on two more cylinders to the car and it became a V6.

 

I am selling my JRSC.
PM me if interested.

 

i would unhook the axles, and shift linkage and lift the motor up out of the car a little...

and about the jrsc not making anything up top? totally false. its a constant 7 lbs boost, once vtec and that boost comes together, 6k-8.5k rpm gets scary quick. as with all power plus modifications, your gonna need support mods as well. intercooler as stated earlier, a koyo/cr/fluidyne radiator for a piece of mind (it gets hot with a s/c), stronger clutch, and of course, upgrade your brakes (atleast your pads and fluid). once installed, you may feel the extra power over-powering the stock lsd, so you may want to upgrade that, but thats up to u. i feel like i have a hint of torque steer if i launch.</TD></TR></TABLE>

That's a very good description of how the JRSC feels once installed. I haven't had mine in for 3 years (removed it for other maintenance) and I'm definitely not putting it back on until I purchase a slew of accessories like you mentioned - the previous owner did not have much to support the JRSC system and that may very well be why the car was in worse shape than I thought (which I figured out months after purchase). Hondata is a nice tool to have too - really easy to make changes from your home.

GAH, now I want mine back in!

In my opinion, I feel like u only have 2 worthwile options, LHT intercooled JRSC or Turbo. The JRSC makes very nice power below 6k, after that it screams pretty nice, and it comes with a CARB EO # sticker

Honestly I think it will take a little more than 6-7lbs with the JRSC to get to 260whp, 9-10lbs would get u there for sure. This goal could be accomplished easily with a nice turbo setup @ 6-7lbs, such as a peakboost kit with a fast spooling turbo for daily driving

The vortech and procharger make nice power up top, but lack it down low, so u will need to decide what rpm range you are looking to have the most usable power. and if its top end pull you are after then a turbo cannot be beat.

 

jackson racing is the way to go if you want a nice power band also look into the lht intercooler setup there is a hole thread prolly about 400 pages in the fi area if you dont find what you wanted to no here

 

You get a nice and smooth powerband with the JRSC.

 

this arguments been done before so many times, and every time there are loads of people saying about how the JRSC gives you more low down torque


if you want low down grunt why did you buy a Honda


the vortech adds a % of the power on top of what is there at the relevant RPM's, so although it may not make as much as a JRSC *cough* intake temps *cough* , its still making more power and torque than it was before.

depends if you want it to drive the same, but with proportionally more power, or if you want to be lazy and not bother to change down to find some torque.

 

that powerband looks crazy

is that 1.6 or 1.8?

 

the user ID on the graph is WhiteITR, so I'm assuming 1.8L

 

My LS has the same powerband (well, subtract 20 ft-lbs). perfectly flat from 2.5k to 7k. that's the wonder of the JRSC.

 

Brad is alive?
