head work is needed -ie larger valves like the 2.0l heads-42x36 with some port work.
Maybe even more compression to 9to1.
A header instead of the HE's will help too.
I have got you to maybe 90hp doing all this, so about 10hp.
What else, maybe going to larger pistons will help.

Actually, if you really tune the engine with updated parts the little 1.7l is quite a good motor.
