Here is my take:
First what are the likely power outputs of each engine. An example the L16 and A15 weights are 30lbs apart but invented in stock trim the L16 makes 15 more horsepower. Also you,need to consider gearbox rules a high strung engine will need a proper gearbox.
Next what are the tracks or track you will be racing on like? The difference between the SR20 and L16 is 400lbs, at a low to medium speed circuit I'd give up some power for a lighter car.
Lastly what is your budget? Let's say you could have any of the engines for free, the big expense is going to be tires and fuel, the more powerful heavier car will use more tires and fuel. A car that is easier on tires make make it possible to keep fresh rubber.
My coupe makes the whole season on a set of tires, I buy them in the fall and so end one season on fresh tires and then start the next season on tires that are still good. Like you I have a choice of engines but stick with the A-series, since I have spares but also because it's the most budget friendly. Just something to consider.
