I am looking at a 76 2.0 engine and was curious if all the smog stuff can be removed and basically set the engine up in a pre smog configuration? like a '73 or '74
I have a pre-smog set of heat exchangers I could put on it. Is the injection harness the same? anything else I would have to consider? Jeff |

Pull the smog stuff ... plug the air injection tube holes and you essentially have a '73 - '74 2.0L.
Wiring harness is approximately the same, but it has a speed controller wired in (white plug). Don't need to use it. As far as I remember the MPS / ECU combination is an 049 MPS with an O52 ECU. '73 - '74 combination will work maybe a little better as it won't be set as lean. I ran one in a '74 for 5 years and didn't notice any difference between it and the original '74 engine. Good enough? |

Thanks, sounds like a pretty easy adaptation.

After the the air injection tube holes are plugged, do you need to vent the heads?

I have a 75. 2.0 d-jet, the air injection holes had been plugged when I got it, I also backdated the exhaust, and all the smog stuff's gone. Currently running pretty good. ( no smog testing in s.c.) |
