Will it be a good idea to buy an ebay turbo kit and swap out the turbo and intercooler? Or should i just invest in a greddy or esmeril turbo kit?

 

seriously?

 

Closed for trolling.

If you are actually serious, then try again tomorrow, only make sure you highlight exactly what you have discovered while researching how to turbocharge your RX-8. If you need material to pull from, try the stickies at the top of this subforum and the links in my signature.
