The power valve screw issue scares the crap out of me... would a 350Z (or maxima) intake manifold (possibly just upper, on the pathfinder lower?) work in place of a pathfinder manifold? I know low end torque would be sacrificed (but it may ahve more top end), but would it work? I was also thinking of maybe fabricating just an upper manifold, like a plenum with velocity stacks inside of it? I dont mind some fabrication, or adapter plates for the TB if necessary. Just a vague idea at this point and looking for some ideas. I know its not that big of a deal to loctite them, but I usually cant leave well enough alone.

I have a 2003 nissan pathfinder SE with an auto tranny. I am more of a manual transmission sort of guy but this car was originally purchased for my (ex)girlfriend to drive, but now its my primary vehicle. I do not care for the way the transmission shifts, it feels to be geared more towards comfort than "performance" or transmission longjevity. I know it was realitively easy in my TH-350 on my old monte carlo drag car to make it shift quicker and harder (a spacer plate with different holes/restrictions between the case and valve body, and 2 removed check balls) and on newer cars you can use some sort of power programmer to increase line pressure and firm up the shifts, but I have been unable to find either method for the pathfinder. All the power programmers seem to just increase engine performance, do they mess with the transmission settings also? Thank you in advance for any information.
