2.2 Need More Power

[Uwon]

Hi everyone,
I recently acquired a Frankenstein '70T. The body is soooo ugly....so I'm not posting a pic of it.



Intention is to fully restore it back to original, as much as possible, save for the motor (matching numbers as far as I can tell), I would like to pump it up to about 200hp, rebuild/strengthen the 901 transmission appropriately.
The motor was recently fully rebuilt by a knowledgeable Porsche trained indi here in Canada. It has only been running about 45 minutes since its completed rebuild. The build sheet includes everything that one would normally replace/refresh except that the crank was not balanced. Exhaust is standard, Webers appear original but who knows.
I come from the 3.2 world so I don't know that much about these earlier motors.
The car, when fully restored will only be used for street and spirited driving, no track, etc.
So here are my initial questions for fellow forum members:
1) Can 200hp be achieved with only a top end disassembly and not a full teardown? If so what combination P&S, porting, cams, ignition, exhaust, Weber mods should be considered?
2) If 200hp cannot be achieved without a complete teardown, what combination would be best suited for street use? I know that this may be considered is a loaded question with many answers, but there must be a reasonable time proven formula.
3) I've read lots about the ST motor but it all relates to the later iterations for '72-73 model years. What were the particulars to the '70 ST motor which I presume was based on the 2.2?
TIA
Johan
