I just started today marking all of the sensors to prepare for pulling the motor for the BB swap. I have a '94 se-r with the low port head so I ordered the '94 service manual thinking it will have diagrams of the low port motor, but no, it shows the high port. I can work with the diagrams it has until i get to the intake manifiold side of the motor and all of the sensors are not the same. Should i go buy a 200sx FSM or am I retarded and should be able to figure this out?

Low-port engines were introduced in '94, so if you have a high-port, you need to see about finding a '91-93 FSM. If you actually have a '94 low-port, and your '94 FSM still shows high-port diagrams, a 200SX FSM would help. There were some early-production '94s with high-port intakes, so either situation is possible...just make sure you know the difference between high and low before you go out looking for a new book. ;)
