best mods for a 07 4L80e?
Car has a 403 Ls3 that had a APS twin kit with upgraded turbos.
What are some upgrades I should do while its apart?
shift kit? clutches, harden input, output and intermediate shafts. Anypump mods?
The car has made 800 rwhp and 900+rwqu @17lb threw a 4L65e
still have some room to make more.
combo should be good for 1000+ rwhp & tq
Thanks
Nick
