Curious if anyone else on the board is running this older Turbonetics turbo. This turbo was on my GN originally when I bought it and now sits under the hood of my T. I made the swap when the T70 went in the GN. As much as I would like to "upgrade", I really can't find a reason to. It spools great (.82a/r and 9" converter) and pulls like crazy. I ran it at 28psi on race gas and a Job Spetter tune in the GN before I went with the T70 and went WELL in the 11s with it. I have been beating the crap out of this thing for over 7 years now I think. It never misses a beat.
From what I understand, the Stage 4 came about as a custom turbo for a GN owning doctor in FL. The turbo became an instant hit and Turbonetics made it a regular in their product line-up.
