Ok the problem is I can decide on a turbo. I was looking that the GTX 3576r and the PT 5858 and 5862

Turbo Compressor ind diameter Compressor exd diameter Turbine diameter HP

GTX3576R 58.00mm 76.60mm 68.00mm 400-600

PT5862 58.00mm 76.20mm 71.00mm 600-640

PT5858 58.00mm 76.20mm 64.90mm 600-620

I see the numbers I understand the numbers but Ive been reading that the gtx will spool but still have it up top and the 5862 wont. But i know the EVo guys are saying the 5858 and 5862 will blow the GTX out of the water as far as faster spool and top end. Does anybody know if that is true? Will the bigger turbine on the 5862 spin it faster or cause lag? Will the 5858's smaller turbine diameter cause it to tap out on the top end. And also the GTX 3576r comes with a .82 a/r and the PT turbos only offer a .63 a/r. im looking for the mid to top end power as my redline should be 7500 or better with a P and P. I could use some real help. Please leave the smart ass comments to yourself im not a noob to cars just to mazdas im used to building hondas and evos and not having to put up with DI. THX in advance
