hi guys!!! im from the philippines and i just got my jrsc kit installed on my car. my engine is a b18c1 gsr stock block with a b18c type r head and b16b camshafts. we also installed a b20 crank pulley to increase the boost and we only got 7psi on the boost gauge ... i was wondering if there are other ways for us to do so we can increase the boost...... i have heard about replacing the alternator pulley. is it true? will it work with the B20 crank pulley? what kind of alternator pulley can we use? should i go for bigger or smaller alternator pulley to increase boost? and how much increase will i get? thanks guys!!!!

MVM and Endyn make stepper pulleys for the alternator that will increase the boost. Here's a picture of one that I have:






You can also use a smaller pulley on the blower, JR makes tham as small as 3.8" and you can get smaller ones, although the smaller you go, the more of a problem you will have with belt slippage.
