1976 2.0L exhaust replacement, Can I put ... Options

[jimkelly]

I have nice Stainless heat exchangers from a 1974 2.0L and want to put them on my 1976 2.0L engine with a bone OE stock muffler from a 1.8L - into my 1972 914?

Or can I use any year exhaust as long as the HE's are from the same engine type as the mufflers?

I have a similar situation. I have a 75 1.8. However, the HE's are not correct for the engine. I am not exactly sure what year/size engine the HE's are from.

We can ID them from pics, if you like. Or we can try describing them...

Headers: Just tubes--they join together (either all four into one, or four into two into one) and exit the car. For a street application, there'll be a muffler of some kind.

75-76 exhaust: Two pipes come down off each head and immediately join together and carry the exhaust forward. Another piece bolts on that makes a sharp turn back toward the back of the car; this is the part that has the heat exchanger wrapping on it. Inside the exchanger, the exhaust is a single pipe on each side. The muffler flanges are triangles.

73-74 2.0 exhaust: Two pipes come down off each head and curve toward the back of the car. The heat exchanger wrapping closes over them, and continues for a couple of feet toward the back of the car. The two pipes exit the back of the wrapping, and connect to the muffler flange. The muffler flange is a trapezoid shape. The bottom of the flange is roughly even with the bottom of the heat exchanger wrapping, the pipes go straight back from the wrapping to the flange.

70-74 1.7/1.8 exhaust: Very similar to the 73-74 2.0 exhaust, above. The major visible difference is that the pipes that come out of the heat exchanger wrapping turn upward for maybe a couple of inches, and then continue straight back to the muffler flange. This is the "kick up" that is referred to. The bottom of the muffler flange would be a couple of inches above the bottom of the heat exchanger wrapping.


Most of the "other" heater parts from the 75-76 cars do not fit on the 70-74 exhausts. The S-shaped ducts from the fan shroud to the exchangers, the J-shaped tubes coming down through the engine tin, the tubes from the exchangers to the flapper valves--all of those are different. The flapper valves are the same, but they can be tough to separate from the rest of the bits.
