we did a garrett 3082r on an inline mani and built cp piston 9:1 comp. engine. if i remember correctly we had trouble making power past 20 psi. we made about 430 or so on 23psi pump gas and only made 480 something on 28 psi with q16. this was also with the e cover so i think the small 2" outlet makes a restriction compared to the full sized cover with the 2.5" outlet.

all i know is what the recipe tells me i bought the car like it is gt30.82 is the turbo
Ok, here is how garrett does the naming of their turbos...
GT = Ball bearing
30 = The family of turbos ( turbine wheel inducer )
76 or 82(your case) = the exducer of the compressor wheel ( the large side of the compressor wheel )
So when you say GT3082 what you are saying is you have a garrett ball bearing, 30 series turbine and a 82 mm compressor.
So what you have is no infact a gt3082....you have a 76mm compressor in a B housing ( im guessing ) with a .82 a/r turbine housing. The turbine housing does not mean you have a 3082 just because the turbine says .82 thats different all toghether.
Your turbo is maxed out around 425whp, maybe 450whp. Take a picture of the compressor housing, that will tell more. Hope you understand all this.

go to this link for the pic its not that good but it all i can do with the light and my crap phone. but i believe its the 82 hot side (turbine) like you said not compressor.
