After 380,000 km's the engine in my ride has retired. I'm in the process of swapping in a fresh A6 with some mild internal work.

I'd like to use a Z6 intake manifold, mainly because the TB mounted MAP sensor looks better than the firewall mounted one, and I'm cleaning up the engine bay while I do the swap. I'm going full OBD1 in the near future as well, but I'm not going to do the Dizzy or ECU yet.

Do I just have to switch the plugs on the MAP sensor harness and at the injectors? Or is there more to this?
Thanks!

I did this a while ago. You need to extend the MAP wires, and the IAT wires. Use your old injectors/resistor box and you should be good to go. I remember needing vacuum caps too... always good to have some vac and coolant hose around.

Whats the difference between OBD2 and OBD1 injector clips?
And will OBD2 clips fit OBD1 injectors?

Ok now that I have the wiring all figured out, What do I do about the vacuum lines for the Carbon canister. The other question I was wondering about is the purge cut solenoid thats a part of the old MAP sensor bracket? Can I just un-plug the electrical connector and vacuum line? What does it really do anyways? Some CRX's have two and some have one, any ideas why?

You can toss them both in the garbage. The only vac lines you NEED are the FPR and brake booster. Rewire the MAP to the one on the throttle body and you're good to go.

I did all this. First, I got rid of my canister. It's cleaner without it and you can still pass etest, hell, i passed mine with no O2 sensor, no TPS, no canister. It almost failed, but it didn't lol. You don't need to lengthen the wires. Simply cut the tape and thug the wires, they will lengthen by 3" enough to reach. The other plug just sorta hangs there. I cut the loom and pulled it all the way back for cleanliness. The MAP sensor verifies proper vacuum in manifold I beleive (Manifold Absolute Pressure, right?). Without it, your car runs horribly and will get 200kms for a full tank of gas...trust me I know...

Thats incredible! With no carbon canister & O2 sensor, the tech should have failed you at the visual inspection before he even hooked the car up. Its cool that you passed though.

(btw you have a PM)

Ya my SOHC ZC was a clean engine. And I went thru a drive thru place, my donut ring had a small leak too. Couldn't hear it so they never bother to checked. The visual inspection hardly ever gets done in the drive thru etesting places I find. Neither my prelude nor civic got one. But what am I complaning about, they both passed.

If your wondering which one, it's Oil Changers on Victoria street in Kitchener. You can get your car etested in 15 minutes there.
