The guy who builds these motors has run a 250 shot on a plate kit with a 750cfm double pumper with great results in his rx3. He recently switched to a trick turbo setup on the same motor build running 31psi with great results so I'm not to worried about the strength of the motor (unless I really **** some tuning up). I just always tune way too safe since it's so basic (using my tunable devices, which are few), so I want to bring out more power by setting it up for what is was meant to do. I know I need to throw more money into it to reach what it was built for, but I'm trying to not waste money buying part that have little to no use (which I see on a lot of cars... all the time). Any other advice helps. Thanks guys.

Your intake manifold isn't holding you back at all. You'd have to double your power before it does. The stock exhaust manifold and a lack of tuning definitely aren't doing you any good though.
A 100 shot is a misnomer. A 100 shot jet isn't necessarily 100 hp. It's not that simple.

I agree, your manifolds are not your limit. The same 100 shot jets on multiple cars will yield very different horsepower numbers. Some might be right on with a 100 horsepower increase...some might be more, and some might be less.
