Any ideas how to get 100-150 more hp out of the engine besides a supercharger?

Nitrous is the only other cheap/easy answer. Other than that, you'll need to do internal engine work: Cams, heads, etc.

And even with bolt-ons AND most engine internals, unless you spend about as much or more what FI would cost, you still won't get much more than about 75-80 more RWHP. And at that point, reliability becomes an issue.

I bolted on a good 150whp in about 4 hours on my Vortech v3 non-intercooled install..

I understand the merit in going NA, and the feeling of acomplishment that comes from building your own motor, but for $3,895 you just cannot beat the whp gains of an "entry level" supercharger kit.

how does reliability becomes an issue?

Anytime you're going into the engine you run the risk of increased failure rate. Modding engine internals, even if done properly, retains some amount of "infant mortality" due to any one of the various parts that were changed or disturbed. I'm not saying that EVERY or MOST modded engines will fail; just that you increase the probability to some extent.

Also, consider that each parameter of these mass-produced engines are slightly over designed or designed with no margin. By modding internals, you're potentially reducing those margins and in some cases exceeding margin(s). You just need to be sure that you or whomever is doing the work knows what they're doing (as if I need to state that).

i hear this will give you 40 WHP:

And it gives your car much better aerodynamics, something a supercharger cant do!

so if i were to go with Intake manifold/ported heads/ camshaft i am actually (ford top end package) putting my engine at risk

If you're not going supercharger at all then a set of CNC ported heads, custom grind cam shafts for N/A, and LT headers. You can also add FRPP intake. This is what I'm going to go with.
