I have a 5-speed. Now i plan on going all motor for a while and just finsihed my upgrading my hole front brake system. Now i want to move on to the tranny. I dont want to get to crazy collage kid hear not tons of money but i get paid really good. I am going to do a phantom grip diff, cuz people are having problems with new skool. Spec stage 1 clutch with alumin fly wheel. i already have ES motor mounts inserts. What else can i do to help give an improvment while i have the tranny down.

Definatley get the safing brackets so your differential pin doesn't slide out and turn your spider gear into a time bomb while driving. (Which is how my first tranmission exploded.)

yea i was going to have them weld the pin in place

No one else has any sugestions!!!!!!

I suggest that you don't get the phantom grip for the reasons that Dino discusses here: http://forums.2gnt.com/dcboard.php?az=show_topic&forum=8&topic_id=38769&mesg_id=38769&listing_type=search.

Internally, the trans is great. It'll take what you give it. If you want to make it better, invest in a good LSD conversion (search for RetroFit in this forum). Run good fluid, use a bigger trash magnet. Not much else you can do otherwise. Rates of T350 failure tend to be low when properly maintained, even well over the manufacturer's input torque rating.
