What does it take to get that intake manifold/throttle setup. That would open up an L27 VERY nicely.

Think I will shoot for that, by next summer sometime. Need to find out what would be the best bang for the buck. Headers or porting is probably also going to be worked on also.

To drop 1.5 seconds your going to need about 100-125 horsepower increase or an incredible increase in torque. An agressive cam might net you about 50 but you may need head work, stronger springs, etc... to go with it. Depending on the cam'* lift you might be able to put 1.7 rockers in for a little extra oomph, but I would just get a higher lift cam since you would be doing it anyway.

N20 would help a lot to get you the need HP if your into that or a turbo setup.

Considering that stock time. Shaving more than a second off your ET takes a bit more work than that.
no way does a stock SE run 15.5... my parents old one ran 16.1 on a cold night

Technically no. But it is easier for sure.
