Well we always heard a rumor that there was a difference in 5 Spd and Auto Cams in the earlier model B16's and well there is.. When i got my car is came over with a Auto ECU but with a 5 Spd Tranny.. So we swapped the ECU out along time ago and the car has been running strong since the build. But the we were talking that I bet my Motor came out of an Automatic.. So it made us pull off the head to check out the Cams.. We Mic'd the Lobes vs a set of 5 speed cams and boom there is a difference.. So we had a set of XSi Cams out of an Integra that we put a set of Toda cams into it so we Mic'd the XSi cams and the lobes were a decent size bigger. So we swapped the XSi cams into the car and boom the car runs so much better.. I have alot more top end and the car seems to react alot quicker and runs alot stronger. So thats my story and I am happier now because the car runs alot stronger off the bottle and I have not sprayed yet on these new Cams..
