Now my turn to ask a question; if you know you are bad at cars, why would you want to mess with a car that has a swapped engine? And before someone else chimes in, spending a few minutes searching either Google or this site for a downloadable service manual for the SR20DET will save you lots of time asking questions and help you be better at cars.

Because I had an opportunity to pick up a decent car and I took advantage of it. I always search google and forums before I ask a question, but I had no idea what this part was even called or where to start so I used this subforum for what its for and asked a question. I haven't looked into a service manual before but if it sounds like I'll have to look into it.
