You have much to learn. I have closed this for now. Start reading first, and only post when you have something clear and precise to ask. Be prepared to list your engine management, supporting modifications, where you are getting your parts from, and why you believe that the compressor maps for that turbo are a good match to the Renesis engine.

Until you can explain those, you are only going to get lots and lots of flaming. Educate yourself on those points first, THEN ask.
