I have a fully built Short block and Head for my new setup. I have a lovefab GT2 manifold,3" downpipe, Precision 750 with 2.5" pipe. I have a GT3076R with Tial turbine housing (.82 AR). I will be running 1000cc injectors with this setup. With running 9:0:1 compression what kind numbers are you guys seeing on the GT3076R @ 20psi or so. With race fuel can the turbo @ higher boost levels make 500whp?? Or is that pushing the limits of the turbo. The other option would be the GT3082R running the Same GT30R turbine but with a different cold side. 2.5" outlet compaired to the 2" outlet of the GT3076R. Basicly I want to match the best turbo possible for the setup that I have. I dont want a laggy car so a GT35R is out of the question.

the most i have seen out of a 30R on s2000 was 506whp @21psi on a bone stock internally F20c. It was also running c16, but still had stock compression. The 30R really is just out of breath by 500whp, it can do it but thats basically at the edge of the compressors ability. The 82mm compressor would be good for about another 50whp before the turbine is out of breath. If I was you i would stick with the 3076R and do somewhere between 475-500whp @ 21-22psi or so. The 3082 isnt a bad turbo either, but the 76mm compressor is a better match to the 60mm turbine. Hope this helps.

More please, I also am interested in this topic. I have read so many great things about the GT30R so my inquiry is not intended there. I myself wonder about the GT3082R when I lay in bed at night. There is always speak of the laggy GT35R, Is there information available as to whether or not it is the turbine or the compressor side that accounts for it's lagginess. Possibly it's both, but I wonder. I am currently getting a quote on a GT3082R so for me this would be helpful information if someone with more knowledge on this topic could enlighten us. The turbine on the GT30R as we know works extremely well with the F20, but to then add the larger .70ar and 5.8mm on the compressor side in concept seems it would be better. Unless it's the compressor side of the GT35R that is the cause of its lag. For me that is the question I would like explained due to my huge interest in the GT3082R, or this could just be crazy talk and I know I've heard that before. Please allow me to bow in front of my fellow FI S2K'ers and share with me your wealth of wisdom on this matter.

The GT35R doesn't fuggin lag! Why does everyone on earth think this?

My turbo is a 30R compressor wheel and a 35R turbine and its made by precision, i'll post the graph tommorrow to show spool but it's make 403@8PSI stock compression.

403@8psi. I wanna see that graph!

I know I have the option of running a GT3076R with a 4" inlet 2.5" outlet on the compressor. The other option is 4" inlet with 2" outlet. What would be main differences be on these compressors as far as the changes in compressor outlet. Right now I have a Tial .82 A/R housing on the turbine, and a 4" inlet 2" outlet on the compressor. Seems to be that the GT3076R is going to give me the spool up and midrange power I want rather than all top end peaky power. Traction itself will be a issue so really finding the best hp to lay to the road is my goal. If I can have 450-475whp with a good powerband I think I would be totally happy. Also I am running a upgraded stock diff with comptech housing, J's Racing 4.30 FD with hardened bolt set, and a ATS 1.5Way carbon LSD. For the clutch I am running the J's racing Hyper singe with flywheel( Basicly Exedy). Do you think that combo will be ok for those Hp levels?
