1) You have what's usually referred to as a 67mm turbo. This is considered an approximate 700rwhp turbo through a 6spd.
2) This turbo will outflow the stock injectors, so running it without an upgraded fuel kit is dangerous. If for some reason your boost control fails, your air outflows your fuel, and melted pistons result (even with race fuel or aviation fuel). You need to get rid of the oem fuel system immediately. Your new fuel system should use at least 780cc (75#) injectors.
3) Boost is not determined by the fuel, it's determined by your turbo and your fuel controller. If you block off your wastegate (or modify the boost controller to achieve the equivalent) your turbo is capable of well over 35psi of sustained boost... However, don't run it that high! You must use your boost controller to ensure that you do not run more boost than the octane of your fuel can support.
4) Are you running an auto or a 6spd?
5) I believe that the exhaust a/r on this turbo is inappropriate for your application (too large). Ask your supplier if you can replace it for a smaller exhaust housing (eg. .80 a/r)
6) The compressor housing outlet is a bit small. See if you can get it replaced with a housing that has a 3" outlet.
7) Which intercooler are you planning to use?
