Most of you know that I am in the process of building 1.625 primary heat exchangers for the 914-6 market.. Danny so kindly has lent me a pair of factory heat exchangers to use as a pattern.. The issue is that the heat exchangers when sitting flat as if they were mounted on and engine the exit flange is off of perpendicular square(word) by about 3/16" .. Both of them are.. So a better explanation would be if you are looking at that back of the car with the muffler off the muffler flange bolt holes do not look square across the back of the car..
We have been discussing this for a few weeks. It should be square imho and some ssis I just installed on a customer's car today do as well.. So the question is what is the general consensus? Either way is easy but square and level makes the most sense to me as all 911 mufflers are built that way.. |

I guess to clarify. Look at the picture of the engine in my shop and see how the straight edge lines up with all the bolt holes. This does not happen with the exchangers I have for a 914-6. Sample.. They are rotated.

I would need to mount my headers on the engine to see if things align. I can do that if you need another look at things. Let me know.. |
