Throttle Body Jamming - Replacement Options? Oversize?

    So I shat my pants the other day. Throttle stuck open while passing traffic on boost. Lifted... But she still kept on at full steam O.O;

    I've already cleaned the crap out of the throttle bodies however I believe the sticking is coming from the butterfly shaft seals as it only sticks under vacuum.

    I intend to upgrade the turbos soon. Not sure to which ones yet... But I'm really not happy with low down torque. I.E. anything under 3~3.5K rpms.

    So the question is:
    Can you get replacement seals for the butterflies? Is it even serviceable?
    Should I just replace them all together? And if so, should I get aftermarket ones?
    Will larger after market types have any effect on improving low down torque? Or even requiring other supporting mods?

    Cheers all. :br:

    Throttle catching on Inlet cam cover vent pipe, that's normally the issue. Just tap the vent pipe back into cam cover

    I'd already checked that just recently... and I had already fixed it about a year ago.

    tassuperkart Its a lie I tell you!

    Unless you are boosting and revving the thing to buggery, upsizing in TB/s will only make you feel better when you tell people you did it!

    Years ago, we did some subjective testing on the dyno on a Pulsar Turbo ET that was boosted to buggery and back to back tested the stock (iirc) 44mm TB and the bigger VL TB (54mm) that every Pulsar turbo owner "must have" to make any powah.

    The results were "spectacular" to say the least!!! Well a spectacular fail. No difference!

    The smaller Pulsar ET TB flows 400Hp plus.

    Sounds like the pegs either side of the throttle bodies need adjusting. Adjusting Throttlebody

    Mine were sticking and too and doing this fixed it.
