Type 4 Engine Reference
One the most difficult parts of working on Type 4s is knowing what year/model engine you have, knowing the model of the cylinder heads, etc. That's where this page comes in.
Right now I have put together two pages for your reference. As the site grows, we'll be working on more stuff, like which parts are interchangeable with what. Read the respective technical article for more information about information of your particular area of interest. For example, if you want to know the difference between the 914 and the Type 2 cases, go to the technical article on crankcases. The information in the articles will generally be more in-depth and thorough.
If you have any information that would be of interest to our visitors, you are encouraged to contact me (see the links in the footer of this page) and share what you know. The strength of this site is sharing information among the visitors.
