Where can I get parts

I need to know where i can get high proformance parts to build up my mazda mx6 engine.  it is a v6 2.5 and i know people buid them up to high horse power but sumit is not showing any parts.  I have never built any import just chevys.  I got this rust and damage free 1994 mazda mx6 LS with 93K and i want to make it as fast as i can.  I dont want to drive it on the street just the strip.  Where are tose guys getting the turbos and parts to make the tuner cars rununder 10 second 1/4 miles
If anyone can help i would be so happy I am not looking for any cheap parts I want this car ro be fast and safe
 
thanks
