    You can mod it and keep reliable. It's just that stuff WILL break more often.

    Ask me how i've broken 3 transmissions on a 3.4 setup

    Cause a part time job can pay for a new transmission!!! Will a 3.4 with pcm tune, headers, 180*, and cai blow a tranny? Would a 3.5 be safer?
    Would an alternative to headers be Powerlog front manifold and downpipe/ubend delete?

    3.6 would be optimal with these.

    it's torque and heat that ends up shredding your trans.

    bigger pulley + more timing = better.

    Every bit of this.

    Whatever you do to the car...if you don't have double, or sometimes triple what your putting into mods, then you shouldn't really tearing into it...because when you spend $200, you end up spending $300+...

    I was going to add that the first transmission wasn't actually dead when i had it built. Flexplate cracked and it wasn't but $2,000 to get a built trans with upgrades AND the flexplate replaced vs $600 for just the flexplate replaced.
    The stock trans was worn pretty badly. Clutches were charred, Input/output was missing a tooth here and there, 4th gear had half the splines missing.

    The 2nd and 3rd were rebuilds of the built trans, TQ converter **** the bed the first rebuild, Channel plate gasket and another i can't quite remember went the 2nd time and car was losing 2qt/day in trans fluid, which made the tq converter **** the bed again.

    4th trans is a charm though, added a trans cooler on the 1st rebuild of the built trans.
    2-3 times daily 1-2nd gear WOT and we're still cookin'

    This thread is too long for the question.

    Theres a million different ways to get there.

    Traction would be your best bet.

    Guy did bolt ons and slicks and resulted in 13.67 or something around there.

    On a 3.8 pulley.

    Headers, Intake, Tune...3.8"

    Slicks.

    13.6 @ 99.

    Also, if that car had rockers and a 3.4"...lol, 13 flat?

    I ran 13.8 @ 99 with PEM's/3" DP & Exhaust/3.5"/1.84 Rollers...but on street tires and no tunez...
