You can use the OBD-1 or OBD-2 injectors if you delete the injector resistor box and solder the 5 resistor box wires on your harness together.

For sure the TA sensor is compatible.
On the Y8 it's located on the intake arm so it's not actually on the intake manifold.
(Found this pic on ebay for a Honda motorcycle... looks the same.)


The purge cut solenoid is optional, but the Z6 one should work with your A6 ECU.
I'm not sure if the Y8 one will work, but I can't see why it wouldn't.
It's just a solenoid that gets clicked open with 12 volts when needed.
The Y8 one has a different plug and I didn't have one so I didn't bother to give it a try.
Either way, you won't throw a code without it hooked up.

The IAC/EACV (same thing, but different name) is compatible.

TPS is also compatible.

The only thing you are left with is the MAP. I'm fairly sure that they are sompatible. I would suggest you use your stock firewall mounted one FIRST and get the engine running with that one. Then switch over to the Z6 or Y8 one and see if it still operates properly.

This guy is using the Y8 MAP (look at the pics and you see the wires stretching all the way to there). Looks like an OBD-0 distributor.

Hmmm... some revision to my previous post.

IAT - TA - same sensor (honda has it listed as TA).
It's the same honda part number for the ED and the EG.

If you get the Z6 manifold then your are fine - use it's TA sensor and keep your old one as a back up. They are the SAME.


You don't get one if you get the MPFI from the Y8 engine because of the TA location on a Y8. 88~95 is screw down onto the intake manifold though a port.
Y8 has it on the intake tube. You would have to get the intake arm from the Y8 to use it's TA sensor.
It's number 22 in this pic


If you use the 88~95 sensor and do like everyone else has by mounting it before the throtle body then it's good to go. (SEARCH)

I have a Y8 intake manifold on my happy little Honda motor.

IAT sensor mounting:
Bottom side of air filter housing cover. Drill hole that's just a little small for the sensor
and push it in there to make an air tight seal. Use 2 screws or bolts and nuts (don't forget
the thread lock ) and mount it all up... you will have to split the wiring loom and pull
the IAC wire harness out and there is plenty of lenght to get it over by the battery without
cutting anything. Tape up the loom all nice and pretty like and you should be good to go!

Hope this pic helps.
