Re: CIS-e and CIS-e motronic experts help me with my swap! (scottamus36)
i've done the swap. it's not hard.
you can use your ecu and knock box. the only gain from the different knock box is a higher rev limiter.....it's not crucial to the car running. and the ecu's are the same.
there's some connections in the harness that have to be moved, some lengthened, some shortened.
throttle switches: connection needs to be lengthened about 3" to have enough slack for engine movement.
coolant sensors: 9a block actually has one of these holes plugged with a 5mm allen cap. remove it, install brown coolant sensor, hook to brown harness connection. the white one in the side of the head is the same one on your harness.
5th injector: i believe you just have to move the wires over. i think they are long enough.
injectors: you have to get the 16v fuel lines, 8v ones will not work, nor will they screw onto the 16v lines.
fuel plate/dizzy: it's the same. so long as it's silver, not black.
oil pressure sensors: you're gonna have them both down on top of the oil filter housing now, you'll have to lengthen one of the two, i think it's the blue one (the one that's normally in the side of the head of an 8v)
coolant temp sensor for the guage: now goes into the side of the head on the 16v. should be a red/yellow wire, but dont quote me on it.
oil temp sensor is in the back of the head now, i think on the 8v it's on top of the oil filter housing. has a green with black wire going to it.
you just wanna cut your harness open, take note of what goes where, and lengthen accordingly, just about everything fits already, as the 8v connections are more twards the center of the engine, as where on a 16v, they are all on the side of the head...some of the stuff will be too long. what i did was i just doubled some of it back inside the harness covering....just so i didn't have a ton of wires hangin out in my engine bay....
here's a pic of the mess i dealt with.
