Going to be tough. The P&Cs are going to give you maybe 6 or 7 hp. More radical cams tend not to like the fuel injection (or vice versa), although some say webcam 73 will work okay (ask Jake Raby).

D-jet tends not to like too many changes. L-jet Fuel Injection seems to be more tolerant. (i.e., D-jet may require more tweaking).

You might pick up a few HP with a free flowing exhaust (try Tangerine Racing), but overall, you're probably only going to get max 95 to 100 HP out of the 1.7. The limiting factor will be the smaller valve sizes in the 1.7 Heads. They are probably the worst of the 914 head designs.

Switching to 1.8L heads may help for a few HP as they have bigger valves and tend to be stronger.

Stick with the sodium filled exhaust valves if you can. They disapate the heat better. You can get bigger stainless valves (=$$$)

Larger valves, porting and polishing are good for a few HP. = ($$$)

Bumping up your compression by flycutting the heads sometimes leads to geometry problems with the pushrods. = ($$$)

For the hastle and what you will probably spend, you may want to consider looking for a good 2.0L motor, adding Euro Pistons and Cylinders, a hotter cam, and carbs, and you'll easily get to 100-100 HP!

Stock 1.7 - 80 HP
96 MM P&Cs - +6 HP
Hotter Cam - + 4 HP
Free flow exhaust - +5 HP
Port, polish, - +5 HP

Lots of $$$$ for about the same output of a FI Euro-pistoned 2.0L...

Good luck.. Search the archives on this board for similar questions.
