Check out the "Results" section of each scenario, I gave an estimated range there. Though all cars are going to be different, it should give you some idea.

all cars have drivetrain losses manufacturers measure engine output at the crank on the motor, not at the wheels as we do on a rolling dyno. Typically, manual transmission cars are around 15% loss while automatics are around 20%. 15% of 215hp is 32.25 horsepower lost which puts you around 180 to 185 hp on most manual transmission IS300s.

depends on what you want out of the car. N/A mods are going to be a waste if you're just going to go turbo in the future, just save your money. On the other hand, boosting the IS is a very expensive proposition.

You've already found a bunch of info on N/A mods, for good information on forced induction: New to Forced Induction? All answers inside!

I'm planning on going with something like Scenario 3 but without the SAFC or EMU and maybe not the Mazzuri Super system too...

Would I need The SAFC or EMU? It only helps to control the ECU right and helps it gain more horse right?!??!

So I wouldn't need it right if I decide to go with:

SRT Intake - $450
Exhaust (maybe just a Axle-Back) - $300 to $600
Cam Gear (HKS are good right) - $250 to $350 total including tuning

So how much Horse would I gain with just these three? +30? +40? +5?? haha

you don't need the SAFC or EMU, but it would get you more power.

don't expect a whole lot out of it, maybe a couple tenths.
