As many of you have read in the past, I've had my Katana 2 for many years. I have always touted how reliable it has been and a great kit......for it's time. We all know these days there are better options out there for a marginally better price, sorry @shinoo! I love the kit and it has been very reliable but after several years and getting the car into working order again over the last month, here are the faults I have had. Keep in mind that this is after several years of hard street use...I have a heavy right foot. . My troubles started 2 summers ago, the many years before that had been perfect, I discovered a sheered intake manifold bolt accompanied by a loud high pitched whine. Shinoo and team were quick to react after seeing my post and sent me a new stud right away free of charge (back then and now...his team's customer support is awesome, so please don't take this as a knock to them). Not wanting to deal with it, I packed it away for the summer 2yrs ago. A month ago I decided to get it fixed, what was discovered was not 1 but 3 broken intake manifold studs. These failures *may be chalked up to the S/C's support bracket that was also broken....the one on the throttle body side which broke in half and leads us to believe caused the failure of the 3 intake mani bolts. I am lucky they were all able to be extracted or it could have turned into further expenses. Getting the car back, I was very happy, all seemed to be in working order and the loud vacuum leak gone.
After a day...I noticed another whine, this time low key and much quieter. I couldn't exactly recall since it had been so long since driving the car but the butt dyno told me...I've lost power. Turned out to be another vacuum leak robbing me. The S/C's bypass valve is now leaking. Just so happened a solar yellow Elise with silver stripes was in for repairs on their Katana kit....go figure a leaky bypass. I will be getting the car back this week but wanted to ask. I feel this is not really a fault of the Sector kit but what could be causing this stress on studs? My first guess are engine mounts and movement. Would love to hear any opinions and thoughts.
