I recently bought a complete Greddy T67 kit for the 7M from Maeso. I have the manifold, DP, oil lines, accordion hose, etc. The kit is nice but I am struggling to understand the turbo lingo and would like help in deciphering the information I have gathered on the web.

This is what I have found thus far on the turbo:

Greddy T67-25G
TD06 hot side, TD07 cold side
Comp Inducer - 2.381"
Comp Exducer - 3.070
Turbine Minor - 2.130"
Turbine Major - 2.402"

What I need to know is if I am the proud owner of a dyno queen lag monster or a decent street-able turbo???

My goals are a reliable DD in the 450-475 rwhp range. I have not installed the kit because I am going to rebuild the motor sometime this summer. Based on my goals, should I keep this turbo or sell it for a smaller one. I was told that Greddy's numbers don't coincide with other companies and this turbo would be comparable with say a SP58. Is this true or false? Where should I expect this turbo to spool at?

The turbo is comparable to a T3/t4 60 trim.. On precisions site the 60 trim with a comprable sized exhaust wheel (2.559/ 2.121 T31 wheel) says it will support 580hp.. In my opinion it will spool quick and give you the hp your looking for..
