I recently blew up my B18A motor and called a place for a newe one when I got there the korean guy told be he had a b18b motor and htat it was the same. I later came to find that it realy isn't I was told I couldn't install it with out an ecu which he didn't sell me with the motor. I called the sales place back he told me to use the Intake off of my old motor and a wireharness from it to. so now my prob is that not all the connections match and there is a sensor on the intake side of the block right next to the oil filter that isn't on the new block.

Now I found a way to use my wiring harness but the only problem is that sensor that isn't on the new block will my car run messed up with out having it connected, I un bolted it and it is a water temp gauge will it affect the way the car runs since it's not on the new block.
