Porsche "six" lineage Options

[TedK]

Can someone point me towards info sources regarding the Porsche six cylinder engines............engine families, exchangeability, etc. Tried some searches to no avail. Trying to decide on engine options for my six............how big can I make the stock motor, what can swap into its place & related fitment issues, those are the type of questions I have.

Thanks for any help,

Ted K

Bruce Andersons book is a great resource for the 911 engines. However there is little 914 specific info.

Its called something like "911 Performance Handbook" and is available from Pelican Parts or probably even Amazon

I would second the Bruce Anderson book. While it is a 911 performance book and covers a wide range of topics, you will get a basic understanding of the evolution of the 911 engine and what changed over the years. And since it is a "performance" book, you get some info on what you can do to each model to bump performance. So if you are looking to do something with your stock 2.0 six or swap to a larger engine, this book as some good info. As mentioned above it doesn't cover much (if any) 914 specific info.

In addition to that book you might also consider a copy of "How to Rebuild and Modify your Porsche 911 Engine" by Wayne Dempsey. While the book is supposed to be a "How To" guide for doing your own rebuild, it also covers performance upgrades. So if you do it yourself or farm out the work to someone else, I think you can learn a lot from the book. Wayne's book covers the 65-89 engines (not the 3.6 and later engines). The point here being that the 2.0 through 3.2 engines were very similar with running improvements over the years.
