Wanting a bit more power out of the 1.7.. options? Options

[Bill Meyer]

I'm new to the 914 world and coming from the 911 side the only thing I miss is the power. Otherwise, I actually prefer the new 914 to my Bahama Yellow 67 911S.

Anyway, it's a 73 1.7 that's been recently rebuilt, the only change being a Webcam and Hydraulic lifters, no idea of specs on the cam though.

What about a bigger bore kit on my 1.7. How big can you go on these cases, and will the FI and stock heads starve it for power? I'm not looking for a race motor, just something that scoots around nicely, say 100-125HP.

Whatever I do I absolutely want to retain Fuel injection. That being said, is my best option a later 2.0, and if so, how much reliable HP can be done with FI?

Thanks for any advice,
Bill

oh, and here's a pic of the new girl.

Nice car!

115-125 HP is realistic with a 2056. 2.0L crank, 96mm pistons, slightly hopped up cam (Raby 9550 suggested) and you can run the factory D-jet. I have a friend with a similar set up running 94mm pistons and he dynos 95 HP at the rear wheels, so should be around 110-115 at the flywheel.

You can use your 1.7L case, but it is advisable that you get 2.0L heads, or have your 1.7L heads modified to the 2.0L configuration.
