Well, in terms of horsepower gains, it depends on a couple of things, and correct me if i'm wrong about any of this.

1) I need it to be a daily driver, so it has to pass the emissions testing we have every 2 years here in Toronto.
2) I'm going to need to put a lot of clicks on the car on a daily basis so i still need to be fuel efficient, i guess the supercharger beats the turbo here.

So I'm thinking of running between 6-8 psi. I'm actually selling my LS, (long story), but i'm deciding on which integra to buy next. I love my car, so i'm sticking with the teg. I'm looking to spend the least amount of money possible here. So I'm trying to decide if buying a gsr would be better than buying another LS and making it an lsvtec. Would i really need to change my bottom end for lsvtec? If i have to pull the engine for whetever reason then i'd rather get a gsr. So a stock bottom end for the lsvtec is what I'll be using.
I'm not considering turbocharging either car, I like the simplicity of the supercharger, and I'm not looking for crazy numbers. Anything to get me into the 14s. So which jrsc would fit a ls/b16a1 tho?
Thanks a lot for your help, i appreciate it
