What is the cheapest combination to get a 1911 out of a 1.7 stock everything?

Here is what i have in mind..

94mm pistons and cylinders.. I've heard 94mm is barely adequate so 96 might be a stretch...

stock cam

1.7 heads bored out to the OD register of a 1.8/2.0

Stock crank

stock rods

dual empi 34 carbs

Any other combination that is cheaper and more efficient?

I don't remember a 94 mm option.....

play with this: https://vwspeedshop.com/Engine%20Calculator.htm

Just plug in the BORE 93, 90. I believe were stock for 1.8, 2.0 and 1.7.
and plug in STROKE 66 or 71. stock for 1.7, 1.8 and 2.0

the liter #s are rounded up. 1.7 = 1680-ish, 1756cc = 1.8 and 1850-ish = 2.0

71 mm crank and 96 pistons gets you 2056cc

then hit the displacement button. You don't have to fill in the other stuff until you want to know the CR, etc....

there are others... google VW engine displacement calculator
