well i just put on my KB 2.2L and im really unsatisfied with it. It makes boost at lower RPM and only 1 more psi of boost. I am thinking about changing out the both the upper and lower pulley but im not sure what sizes i should go with? I am hoping for 15-20 psi of boost on 93 octane. Also i was thinking about some new idlers to compelte the pulley swap any ideas?

how much boost are you running now? are you running the stock fune systen? I love my kb. I have a 2 3/4 pully for 17 pounds of boost with a stock lower. and I put down 606 rwhp and 630 tq. If you take a look in my sig you will see what i have done and the horse i am getting. If I change my shorty headers and get longtubes it will get me 50 hp and if i change to a 2lb lower to get two extra lbs of boost (bringing it to 19) I will have 700+ so it realy depends on the set up that you use.:thumbsup:

EATON @15PSI - IS A BIG GAIN WITH THE VOLUME FROM THE KB, IT SHOULD PICK IT UP LIKE CRAZY, KEEP IT BETWEEN 15-17PSI AND GET A GOOD TUNE. YOU SHOULD BE VERY HAPPY WITH IT, GOOD LUCK:thumbsup:
