914 displacement increase questions
Hiello. This is my first post to the forum. I recently bought a 1.8 liter 914 motor, and rebuilding it will be my winter project. I have a couple of real high level questions to start.
If I want to increase displacement, is there a big difference between getting there via increases to the bore versus the stroke?
How much can I bore the existing cylinders? EBS said 96mm isn't a problem, but what about 100mm or even 102mm, assuming I'm willing to machine the case?
How much displacement will the stock 1.8 liter heads support before they choke the motor? I realize I'll have to machine them if I use bigger bores.
Thanks everyone for your help
