So here is the skinny on the SR20DET rebuild…
We found a lot of problems when the motor was pulled. The oil pump/front cover/seal was leaking, the head gasket was weeping on the front and back, the water pump was super notchy, etc. A bolt had backed out of the power steering pump and eaten into the pulley, so that was about to turn into a disaster. Not to mention the fact that the stock T25 turbo was letting go. I have been collecting the necessary parts for a proper rebuild for several months now, and I almost have everything engine related that I need. Here is a list of what I have ready to install:
