I am restoring the 1973 914 my dad had when I was growing up. It has a 1.7L motor. I know I will need 2.0 liter heads. What do you recommend. There is a great price variance. I assume I will also need 2.0 headers among other things.

Are you sticking with fuel injection?
I built a 2056 from a 1.7 using almost all AA Performance parts. I went with 42x36 heads round port. Part of the selection process is understanding how you plan to use the car. With stock fuel injection the limiting factor is intake runners and throttle body. My experience with building engines in the past… it can be a mistake to over size the heads when you have the other limitations. My car is fine… it has good power the comes on predictably. It’s no hot rod… but it meets My goals and is a good reliable driving toy. One note… if you are using DJet make sure the know to drill and tap for the temp sensor. Also you’ll need to decide on head vents. I went without and it breaths fine. I have about 5k on the engine and it works well for me. |
