    The first thing to upgrade is the valve springs and push rods. They are the week link on higher rpm's. 6k isn't to bad, but does your 98 have the original springs still ?

    the car has stock valve train Still and I figured I wasent gonna go past 6100 so it wouldn't be too bad on my valvetrain is it a bad idea? I have the weak 273 gears and right when it shifts it puts me at 3800 rpm I want to be in the 4100 rpm range

    You'll probably be OK, but those stock springs are weak. If you would upgrade to the comp 918 springs and a good set of push rods, then you could set the rev limit to 7000 and not worry about it ! If you remove the rocker assembly's & put air into the spark plug hole, it will hold the two vales shut at a time to swap the springs. One afternoon to do them. Not too costly either.

    a stall would be the way to go to get those post shift rpm's up.....

    Today I had my tuner raise my shift points 1to2 at 6000 and 2to 3 at 5900
    it feels like it moves faster but it could just be me by summer I plan a 342 z06 differrential swap and a nice stall hopefully that Will net me a low 12
