So what car would those be appropriate for?
Bob B
early 901 / 911 hmm I belive up to chassi number 700 ish but not sure

I think much further. If I recall correct can the answer be found on this board in factory documentation. At least all Solex engines had them?Quote:

I think change was later too - possibly mid-1966 when a more efficient design was installed. Would be interested to see date of change confirmed in eg factory documentation as suggested
See this thread. All the way till the end of 66Quote:

And Jon I presume the real reason to have the restrictors on the “normal “ until the new engine was introduced was to lower the power output of the normal otherwise it would have been too close to the S as there are plenty of examples of early engines even with almost no modifications making close to 67S power figures- or at least close enough to worry the sales department about how many of the new S they could sell or what price point they could achieve
absolutely...to quote the service bulletin M16/66...Quote:

So, which version was used from 68 on? Or are the 67S heat exchangers unique?
Hugh, I think that's the common view and probable reason, although I'm not sure if Porsche ever publicly stated that.
The 901/06 engine was developed for a better driving experience in the lower engine speeds.
I believe the '68 models continued to use the '67S version unaltered.Quote:

Just came across some images of these early heat exchangers in my 1965 edition workshop manual.
Are these heatexchangers still available ?
Yes I got a set on stock
Pls send me a email to early911parts@gmail.com
