So i finally got everything done on my swap. I have a 94 civic ex now with a b16a sir II and a y21 with lsd. I actually got to drive my own car!!!! Well I get in, the ecu throws no codes except a knock sensor after a drive for about a minute. But.... It has no power what so ever. My car was faster when I had my d16z6. It drives beautifully but when i floor it the power isnt there. My friends had a stock b16a sir I in his 90 hatch and it would throw you back in your seat. The motor isn't making any noises except the vavles need lashing. Does anyone have any ideas of what is wrong? Does the tranny have such long gears that im not going to fell the power? I do have one vacumn hose that i cant find where it goes. It is thin, small hose off of the cylnider on the fire wall right behind the transaxle? Could that be it. I appreciate all you guys have done for me so far, but I am really bummed that I spent 3g's and my car is underperforming a d16z6. LEon ps Vtec is super loud when it engages, doesn't seem right.
