Answer 1

Amount of displacement is not the only thing that determines power output. The type and size of the induction system, the number of valves per cylinder, the size and type of exhaust system, the cam/cams profile, and other things affect power.

Answer 2

Engine power isn't totally dependent on size. Compression ration, valve timing and breathing capacity of the head, ignition timing, Fuel injector or carburetor size, exhaust back pressure, combustion chamber swirl, computer chip and software variables, and a whole host of items determine the eventual power of any motor. The old Jensen Healey with a 4 cylinder used to smoke Corvettes and a lot of other large displacement cars back in the days and it was a 4 cylinder. However was highly tuned for vast amounts of power in a small package.
When a manufacturer decides to "boost" up the power of a motor for their car, they look not as much at the size of currently produced engines, but more at the "structure" of the motor. How thick are the cylinder walls, how tough are the crank and bearings, is the head assembly strong enough, etc. That is their main determining factor and not actual cubic inches.

Answer 3

Yes it can. If you insert a turbo in a 1.6 it will have more power and torque than a 1.8. Also if you modifiy the VTECH mechanism in the 1.6 to lift the valve more and longer at higher RPM it will produce more power than the 1.8

Answer 4

i love honda to strart of with do you have a doch with vtect
yes no
if so then after market in take pipe with pod filter ]
get after marked turbo kit with computer and intercooler
get good oil for gbox because they go boom if non slip diff i know i did 3 have fun and have some money to get it done fast as you will you know why
another thing
get the 1.8 cams they bolt straight in and give better power
