Greddy Turbo working on auto RX8
Hey G-Gray dude, I live in San Francisco, since we live in the area that is very close to each other, I would really like to meet you and be friend with you so we can share our idea to make our car strong. I am really looking forward to it. Especially i want to see your car turbo charge in my own eye.

I heard rumor that Greddy are no longer produce any rx8 turbo, is that true? I check the internet recently especially ebay, there only a few left. If they dont make turbo anymore, what other option do we have?
I have questions about the GReddy turbo...do I need the emange with the cobb AP or can I use the Cobb by itself are there any other parts i should upgrade to withstand the power of the turbo
Check out Mazsport's 300 series turbo. Scott will help you get the right setup for your car.
As far as upgrades, depends on what you plan on doing with the car, and how much boost you plan on running. If you are not planning on tracking the car and sticking with the stock boost levels of the greddy turbo kit, I'm guessing you would be fine as is. If you plan on going for higher boost levels, at the very least you'd need fuel system upgrades. If you plan on tracking the car, you should look at upgrading the cooling systems.
If you autocross, my best guess for upgrades (assuming the standard greddy 6 psi) would be make sure you do something to get the fans on sooner (like Cobb AP or Mazsport cooling fan mod). I would also recommend a second oil cooler. You can pick up a used cooler and lines from a parts car, or you can hit up Mazmart for a new one. I'd also recommend switching to a more water-heavy coolant mix. The Mazmart water pump is also a great idea.
If you get all that and still end up having cooling issues, you can also look at Ray's radiator.

I really want to hear the sound of RP supercat with greddy exhaust and MM cobb acessport.
