Rebuilding my Trans, what to order?

[Cammaxon]

I just got off the phone with Jack from Jacks transmissions, I have a pretty good idea what i'm going to get but wanted mitsustyle input

Welded center diff for $50?
orrr
4 spider for $399?

I have heard many people complaining about how crappy it is to turn with a welded center diff, I refuse to stick with the 2-spider, and the 4-spider is $350 more than having jack weld mine up. HONEST opinions.

Stock 1st gear with new synchro?
orrr
Evo 3 double synchro and evo 3 input shaft for $319

I wan't to rev my lime green spilner mobile to 8000k rpm, launch it like Apollo 11, all day long no problems.... and my goal is for 500whp (up a solid 100 from current)


Which brings me to clutch disk, price isnt a big deal they are all within $20
6-puck sprung? (my choice unless u can convince me otherwise)
6-puck solid?
Street disk?

The order goes through tomorrow so w/b asap!
