Ok Guru's. You guys know a hell of a lot more than I do. I want more power and I refuse to get passed by a GTR on the highway again. I have been looking at nitrous and weighing the pros/cons. I have read a LOT over the last couple weeks. I have a pretty good general idea on how to make it safe on a GEN 4. With the info I have been told by some good reliable people lately. The tuning issues may be coming to a completion and tuning may be able to be done by flashing the ECU in leiu of the full custom wired in ECU. Supercharging a GEN 4 sounds like it will be possible soon. With the exception of the intake being two throttle bodies, and not one oval compared to the GEN 3. Is the front of the block for the mounting points the same? Essentially would the install of a PAXTON be IDENTICAL less the plumbing from the intercooler to the throttle bodies?
