What up grades can be done to a 1.7 engine to gain more performance short of swapping out with a 2.0? (Factory fuel injection)
Also, I can’t seem to find a “Topic Search” option to click on to find subjects I have questions about so I don’t have to post inquiries about subjects that have already been covered. Thanks |

Less weight & high octane gasoline. I prefer nitromethane myself.

Swap heat exchangers out for headers. That's the biggest available performance increase without increasing displacement. But you lose heat, if that matters.

This was a 1.7. It was first a 1911cc, which is just pistons and cylinders. Then by putting a 2.0 crank, rods and pistons, a little head work and it is a 2.0 . The heads were the biggest difference. But these 1.7 heads work fine with a little work.
