    LT4 Magnaflows Resonate Horribly on my LT4

    When does the ZF tranny oil need to be changed?

    Stick to the ZF recomendations of GM or BMW oil. I went with Redline synthetic with an extra bottle of limited slip additive for the rear axle. You have to suck it out or drill a drain hole.

    New Opti Installed now high RPM missfire

    Still think the Delteq is a good design Sorry for the confusion. I replaced the stock opti as a preventive measure with a new cheap ebay opti still using the Delteq when I replaced the water pump again. The Delteq is a good design in that it removes the high voltage/arcing/corona etc. and only...

    Which type of flywheel?????

    The short throw shifter from ZF Doc would have been nice. As far as trans oils--tried them all from Redline Synthetics, etc. I think it was 75W-90 all the way up to 75-140--Only quiet when cold in the mornings otherwise no better than the 10w-60 from Castrol/BMW. The thicker oils did exhibit...
