What belt is needed when a CRV pulley is used with a JRSC on a B18B? I have searched evrywhere but have not been able to find any informaiton on the belt that is needed.

 

do you knwo the size of each of the pullies? size in mm would make things the easiest but if you just measure them i could still help you out...

 

Off hand, I don't have the size of the pulley's. They would be the stock CRV and what comes standard with the JRSC for the Integra B18B.

 

I wished that I could get the dimensions. I am not near the parts, they are in PA and I am overseas with the military. I have been piecing my project together for the past few months and the only thing I need now is the belt size.

Maybe someone could ring in with some numbers to help me out.

 

it should net u around 9-10 psi. make sure u get a FPR/new injectors and tune it or its gonna run like a biatch ill be doing the same thing soon and street tuning it with uberdata

 

Here's my parts list so far:

JRSC
CRV Pulley
AEM EMS (self tuning with Innovate LM-1 w/rpm converter) then dyno time later.
RC 310cc
Comptech Icebox with K&N drop in
Stock wires, rotors and 1 step colder plug
JR thermostat
B&M Fuel pressure gauge and regulator

Since I want to keep the stock look and sound, I will be keeping a bottleneck in the system, my Comptech 4-2-1 header and 2-1/4" carsound cat, and ITR exhaust.

 

unfortunatly i'm not that good to know the pulley sizes off the top of my head for Hondas but if we were talking VW Corrado i know pulley sizes across the years...

but here's the easiest way to do it... find out the Dayco belt part number that is equivalent to the one you have for the B18 (most auto parts stores have this gauge thing that will measure how long a belt is... i am 100% sure pep boys has one i've used it many times) Dayco part numbers for their serp belts are just how long they are in mm. so say the belt it 800mm the dayco part number if i recall correctly is 800. and if i am mistaken i know Dayco does base their part number off of the length so they may have a number in front or the end probably to signify how many ribs, but i think it's just length. so then you find out the stock pulley size. then the new pulley size. if measured in american convert to metric. 1 inch = 25.4mm... now take the 2 numbers and find the difference in size. then take the difference in size and apply it to the belt size. if the pulley you are putting on is bigger than the belt size needs to be bigger by the difference in size of the pullies. or if the pulley you are putting on is smaller you need to subract the difference in size of pullies from belt you already have...

hope that makes sense to you

 

a type R pulley would b pretty sweet, i know its not larger like the b20 if thats the reason u choose it but, if possible i cant see why its not u could run the belt like a serpentine belt and that would be damn cool, but if i rember right the JR sits over the A/C or Pwrstrng pully(o and when u buy a belt a number before the "800" is like 4800h or something the 4 is the number of ribs on the belt which is kinda important and the h is BS just sounds cool)

 

Thanks for all the inputs. It helps.

Once I get the diameter and the belt that comes with the kit, I should be able to work it out.

I know this has been done before, it's just sort of odd that noone has the belt size that is needed.

 

Stock Belt Sizes
AC = 31" = 790mm
PS = 36.5" = 930mm
Alt. = 33" = 835mm
6psi JRSC Belt Sizes
AC = 31" = 790mm
PS = 36.5" = 930mm
Alt. = 31.5" = 800mm
Blower = 24.5" = 620mm
9psi Stepper
AC = 31" = 790mm
PS = 36.5" = 930mm
Alt. = 31.5" = 800mm
Blower = 640mm
10psi JRSC with CRV Pulley Belt Sizes
AC = ????
PS = 900mm = 35.5”
Alt. = 850mm = 33.5”
Blower = 24.5" = 620mm
8psi JRSC with Blower Pulley Belt Sizes
AC = 31" = 790mm
PS = 36.5" = 930mm
Alt. = 31.5" = 800mm
Blower = 23.4"-24" = 595mm-610mm

Here are the numbers for your set-up.

10psi JRSC with CRV Pulley Belt Sizes
AC = ????
PS = 900mm = 35.5”
Alt. = 850mm = 33.5”
Blower = 24.5" = 620mm

How much hp can the 310cc handle ? I was under the impression they are not enough for the JRSC with the CRV pulley.

 

The JRSC for the B18B doesn't put out as much as the one for the GSR or TypeR. I am figuring about 200hp at the wheels, so 310cc should be enough.

 

oh i didnt realize you have an LS,
