Whats all involved to increase the beta's displacement from 2.0 to 2.2? And how much of a power increase could you expect by doing that?

 

depends on why you wanna stroke it

 

you could bore it out by 40thou and that prob would drag displacement to 2.something

custom crank would be required if you want to stroke it out to 2.2L

 

I often wondered this too. If the stock 2.0 is rated at 140 hp, then a 2.2 would have to be a bit more right?

 

I did the calculations once when I bored my block for the 83mm Wisecos, but it just barely got to 2.1L


Stroking a small motor is pointless. Just turbocharge it and get 3x's the power.

 

its not rated at 140...its rated at like 132
and thats flywheel ratings

a 2.2 would probably give you 20ft/lbs IF THAT and youd lose top end in the process (you dont really gain hp in it, you gain torque stroking a motor)
