This is a tough one to answer. I think you will get a lot of opinions, and some of them valid. (IMG:style_emoticons/default/biggrin.gif)

I'm in a similar boat. After a lot of consternation, I basically decided that modifications that Porsche made to improve safety and reliability were acceptable. I went through the tech / service bulletins, recalls, and engine enhancements / evolution found in the Bruce Anderson and Wayne Dempsey books. My "acceptable upgrades" list ended up something like the following, in no particular order:

• Stainless steel fuel lines
• Carrera chain tensioner kit
• Pressure fed chain tensioners
• Case savers
• Aluminum valve covers
• Chain tensioner idler arms
• Engine tin air baffle mod

Other than the stainless fuel lines, it is doubtful that anyone but you could tell the above was done. An eagle eye might notice the Carrera tensioner kit due to the oil line fitting?

While I think a lot of people would have modified the head to take larger piston cylinder set, we left ours at 2.0L.

FWIW-Ours is a original 914-6, with numbers correct (but not numbers matching) engine and transmission. I did a complete teardown on the engine. Transmission was sent out and put back rock stock.
