i have a jrsc kit on my b18c1 engine .some people told me that when i put a b20 crank pulley on my engine it will raise the boost higher..... is this true? plus are there any other alternatives that i could do on my jrsc kit for b18c1 to adjust the boost to make it boost higher? rather than buying a high boost pulley kit from jackson racing... pls help me..... im from the philippines and its really hard for me to get parts overhere thats why im looking for other solutions to make my jrsc kit to boost higher.....coz its really hard for me to get a jackson racing pulleykit. again thanks so much! hope u understand me.

 

A difference in diameter with any supercharged car makes all the difference when it comes to a crank pulley. You would have to measure the difference in sizes to get an accurate reading.

If the b20 crank pulley is larger, it will raise boost since it'll turn the supercharger more for each time the engine turns. Or else you might be able to find a smaller pulley that will fit on the supercharger, that would have a similar effect, I don't know what your chances of that are though. Good luck

 

do either of them on a 7psi JRSC and you will heat up the rotors enough to cause the rotors to eat into the case

Please read this thread for a suitable alternative to the CRV crank pulley. I had it on my JRSC GSR for over 90,000 miles.
