Hello,
I found a GA code '74 2.0L with low miles to use in my '72 1.7. Are there any issue that need to be dealt with? Straight swap? Any insight would be greatly appreciated. Thanks, Mike |

Thanks, Mike If you get the whole motor with the MPS and the ECU, it's a bolt in. You may want the heater blower bracket, too. The Cap'n |

Does the 2.0 include heat exchangers?

with the 1.7 exhaust you will lose some HP.
You will need to change the motor mount brackets on the 2.0 to the 1.7 mount. That's it. |

Thanks to those who responded.
I do have other questions, which exhaust manifold gasket do I use 039.256.251 or 021.256.251.A ? I am assuming the 039 because the gasket fits in the head. As I stated, I will be using my 1.7 stainless steel heat exchangers. Also can I use the 1.7 deceleration valve on the 2.0 L ? Thanks again, Mike |

I thought the copper gaskets were the same, but then I didn't pay attention to the part number. Use the 039.
I would tend to believe the DeAccel valve is the same. As you can tell, it has been many moons since I have owned a 1.7. |

OK I have most of it figured out, except for the heater fan connections.
My 72 has the fan connections within the engine wiring harness. The 74 2.0 harness does not contain the fan wires. Could someone show me what the correct connections for the heater fan in a 74 model. Thanks, Mike |

Didn't all the SS H/E all come spec sized to the 2.0L? Thats probably why you have the Manza exhaust. (IMG:style_emoticons/default/confused24.gif)
I don't know this but I remember hearing something a few years back! (IMG:style_emoticons/default/beerchug.gif) |

(IMG:style_emoticons/default/beerchug.gif) I am using the stock 1.7 muffler hanger, maybe my third bracket by now. 2.0L bracket is different, but you may be right about the inner diameter of the SS H/E's I compared the exhaust manifold sealing rings and it looks like to 039 version has about 1 millimeter larger inner diameter than the 021 version. I will be able to compare the H/E's when I swap the motor. |

IIRC, the 72 is the odd one for the heater blower wiring. I believe the 74 has the wiring in the main wiring harness. You may wind up needing to add the power and ground wire for it.

I don't know if the engine harness from the 72 works on the 74. If so, then you're good.

The fan will work that way, but the FI has a different layout. Rich |

It is the engine wire harness that I have a question with. Thanks, Mike |
