I have a set of real nice 75 2.0 SS heat exchangers. I was wondering if they will fit my 1.8. The flange that attaches to the muffler on the 2.0 is triangular in shape, while the 1.8 the shape is more retangular (trapezoid). Is there an adapter or do you just buy some sort of flange for the 2.0 that would replace the flange on the muffler (i.e. weld).
My 2.0 heat exchangers from the looks of them would probably increase my exhaust flow...thus my air flow through my L-Jet...hoping to get a few more hp.

the stub tubes and the way the piping curves around is sort of a pain to deal with. you will also need the 2 correct pieces of tin that attach to the hes and the case.

The late (75/76) HEs are known to be less efficient. Save your money. Yes, they'll fit. ALL stock type HEs fit all the T4 engine varieties found in the 914. BTW, they're not what we would call SS HEs. The actual exhaust tubing is the same old steel material as the early units. Why do we have this question nearly every week? The Cap'n
Triangular flange == 75-76 exhaust == el sucko.
For the late exhaust, you'd need to swap all of the heater parts out as well. All that on top of decreased performance, even over the stock 1.7 (and also 74 1.8) exhaust!
What you have is better than what you are looking at getting.

a lot of people mistake the late style HE ('75/'76) for stainless because they look shinier (is that a word?) than the early ones ...
there were *never* any stainless HE's from the factory for the 914. ever. all stainless HE's were aftermarket ...
post a pic of the supposed to be SS HE's and we'll let you know what you got ...

So the 2.0's are no better than my stock 1.8 heat exchangers--it was worth a shot--Andy, you're right...the shiny metal made me think they were stainless. PS the picture of these 1.8 exchangers are not mine, just handy. I have a set of both.
