Comptech with 7# pulley puts down ~300whp. No engine managment or larger injectors needed with that setup.

You are going to drop 5K on a supercharger with no company behind it? If a vendor was selling a comptech blower BRAND NEW for 2K, i might, MIGHT, consider it. Get Vortech

well the way i see it dude the company whom makes the blower is still in business, and everything else is a stationary part, and wont fail. Am I wrong? keep in mind this is my first honda. I've always bolted upgrade kits to VWs.

Turbo - you'll be happier in the long run. Ride in a SC and turbo S and you'll see that the difference is like a Miata vs. an S2000

well I AM much more familiar with turbo setups. I ran a T68 ceramic on my last car but it was turbo from the showroom. Will this car handle a snail that big with stock internals????

You're fine up until 10 psi of boost. More than that and you typically need a built bottom end or a 3mm headgasket.

The stock shortblock is estimated to be good up to 600 hp, so a thicker headgasket to lower compression will allow you to boost higher to compensate and it's fairly inexpensive.

As you can see, I'm making some nice numbers on a very small amount of boost and lowered compression - turbo setups are very efficient and keep the stock powerband very well. My dyno curve is extremely linear as you can see:

This is off my wastegate spring, 7psi (it will be even more refined when I go to retune and get a 15psi setting):
