MazdaSpeed MX-5 upgrade questions.

MazdaSpeed MX-5 upgrade questions.
I have an 04 MazdaSpeed MX-5 and from what I've read it has 8.5 pounds of boost and around 178 HP. (to the crank I'm sure)
Q:1 My goal is 200HP so I only need to gain an extra 22HP. Any recommendations? I have done the search but I haven't found any threads building on the MazdaSpeed which has a factory turbo.
Q:2 How do I increase it to 10 pounds and will that hurt the stock engine/turbo?
Q:3 How do I make the pshhht louder when the wastegate kicks in?
Sorry for the 3 questions in one thread but I didn't want to crowd the forum with 3 different threads.
Thanks in advanced, Josh

Also, the whoosh you want is outta the blow off/recirc valve... and you're not going to get it with the stock ecu because that air is metered... if you vent to atmosphere the car is going to spike rich as it has already measured that air. Also, I believe that the stock valve has problems holding above 8psi because if its design, you might wanna get a DSM valve... but really, read this.

200 RWHP isn't too difficult (or expensive) on the MSM. I see somebody has already linked to mazda-speed.com. You can take the IHI up above 10lbs if you bypass the electronic boost cut, but with your goals that's unnecessary. Most MSM owners seem to use recirc valves rather than BOVs. They're reasonably loud if you care about that sort of thing.
Replace the stock throttle body inlet and recirc valve early on.
