i have 90k on my g35 coupe 6mt and i was wondering if there is matenence that should be done around 90k. the only mods i have right now is jwt popcharger,ztube,plenum spacer,and testpipes

Shocks and bushings if those haven't been done before. Those are the first that come to mind. Then check your belts too.

I believe you do a transmission flush at 90K?
