I picked up the 02 z last week and plan on taking it to the track within the next month or so.

dumped moroso spiral flow
55# injectors

ftra
ported tb
built 4l60
tci 3500 stall

Before I go to the track Im going to make a few changes:
swaping the spiral flow for a dynomax bullet
swap the tci for a circle d 4c 3600-3800
msd wires
ngk br7ef plugs
adjustable lca's
!swaybar
add a second stage, 75 shot out of the hole another 75 in 2nd
275/40/17 mt dr's

Im thinking it should do a 11.5 on motor and a 10.5 on the spray, ideas?

 

I think 10.50's is pretty ambitious with all of that nitrous and that little tire.
I'm going with a 10.85.

 

thats the reason for breaking the shot up into two stages

 

I still think it's ambitious. I just don't think you'll have enough power and a good enough 60' to run a 10.50. Hopefully I'm wrong...just my opinion.

 

I think you should come close if the car will hook. Good luck!
