I did a search and really didnt find the answer to my question. Is there anyone with the JR supercharger on their type r? I ve got a 2001 with AEM intake, that is it so far. I was really hoping to find out what people were getting for an increase. Is the increase worth it, do i need more than just an intake to get good punch, what times are the S/C type r's getting?


Thanks in advance for the help and advice;

its really hard to S/C a ITR and get GOOD reliable gains from it. For the money, i would just go turbo.

 

What kind of gains and costs involved with turbo on the itr?

how much hp are you trying to acomplish..

let me estimate about 200-220whp for strartup supercharger (but you're not guaranteed these numbers), 230-280hwp - you will make at least that on stock hype r with any turbo kit..

nitrous - is the cheapest of all, if you need ocasional thrill, and not all the time.. -- you may want to consider that option..

whatever you do, remember, you only get mad bov sounds with turbo.. j/k

 

as far as cost, the more hp you plan to make, the more stuff you might need to replace to compensate for hp, such as internal engine parts, suspension components. - look around forced induction forum..

in general, from cheapest to more expensive - nitrous - supercharger - turbocharger.

 

Really just looking for low 13's in the quarter. A reliable sports car with some snap. I am completely aware that it takes a big wallet to get it going fast. I am curious how much i would have to do to get these times. Everything is relative, for example, if a mustang for example runs 13.2 in the quarter with slicks, and my R will do the same with slicks, then the overall verdict is that the cars are the same on the street. I hope im not confusing.

Thanks again!!

mustangs do good in 1/4 mile because of rwd, rwd helps with 60 time, faster 60 time, faster 1/4 mile.. thas why they might match your trap speeds, yet manage to hit low 14's to high 13's - mustang gts that is..

if you want to do good in 1/4 mile, get turbo - pretty much any turbo kit will make enough hp to go past low 13's.

u r looling around at least good 8k canadian to have in done and tune.
turboed my car b4 and didnt like it, plus the shop who did my turbo was an dumbass, didnt hook up my VAFC right, so i took it out

 

the JRSC is a really nice package on an R. of course, max hp will not bve as high as on a turbo, but driveability is fantastic!! tuning is a must and i would suggest using a com,plete hondata system. if you REALLY wanna get good 1/4 mile times, do it right and get a good traction control system. these are very inexpensive in the grand scheme of things and realllllly help to lower the 60' times especially in a fwd car. this will nmake the car MUCH faster down the 1/4 mile and will be better money spent than on trying to get another 25 hp from the motor. i LOVE my jrsc ITR and would not trade it for anything other than a nice race prepped 2.1 liter from SGT ... bt that costs QUITE a bit more !!

 

Since you are talking about 1/4 times then you may want to go turbo instead of supercharger. The jrsc provides more low end torque than a turbo. This is better for autocross where you are constantly turning and downshifting into lower rpms. Turbos don't have the immediate throttle response of a jrsc, but they provide higher peak HP. This is better for straightline dragstrip acceleration. However, BEFORE YOU SPEND ANY MONEY do some research. The forced induction forum here has a wealth of information on this subject. I also recommend the book Maximum Boost by Corky Bell.

You can get a complete jrsc system (or turbo) pretty cheap if you scan the classifieds here and also the "forced induction integra" forum at hostboard.com and ITRCA.com. Just make sure you get everthing you need for it to run properly.

As for reliability the jrsc is warranteed for 100,000 miles and doesn't require any maintenence other than priodically checking the tightness of the belts. You will here a lot more stories about problems with turbo, but there are several reasons for this. First, there are more turbos than sc's; second, these turbos usually run higher boost levels than the maximum of 10-11 psi on a jrsc; and third, there are a lot more "junkyard" turbos pieced together by guys who are less than experts.

No matter which way you go you will need proper fuel and timing control. Th jrsc Boost Timing Control and MAP controller with high pressure fuel pump will keep you running safely and smoothly at the stock 5-6 psi. If you up the boost (and you will within a year) then you will need larger injectors and a different fuel management system, but the BTC is adjustable to higher boost.

The jrsc web site has a dyno graph that shows an increase from about 165 to about 210 whp with the stock 5 psi pulley. This is overstated by about 10-15 hp, but it is still a major increase.

BTW I have a jrsc with boost upgrade (7-8 psi), AEM CAI, Kamikaze header, and 2.5" exhaust. It is my daily driver, and I love it. It has 75K miles on it and has been boosted for over 30K. I have had one belt break on me, but it was just the sc belt, so the car ran fine without it. I recommend that you order an extra belt so that you will have it just in case.
