Drop the transmission and put in an upgraded Level10 Torque converter with a 3,200 rpm stall. (Talk to Sam @ Level 10 and tell him Dan sent you, $400 for the upgrade vs $500 retail.) Next, add you a good sized tranny cooler like Eric Adkins talks about on www.sentra.net. Last, you add the turbo kit from HS! You'll be all set, no turbo lag, you'll be launchin at 3,200rpm off the line in an automatic. I wouldn't be surprised if you get into the high 13's or low 14's with that setup.
In the case that you have an extra money to spend, get the rebuild kit from Level 10 or their full automatic transmission. That'll hold 600hp/500tq and comes with a lot of stuff (throttle oriented shift kit, superpump, hydrosystem, clutches, bands, etc). The special prices have to go through through Sam @ Level 10 for any discounts on Nissan Performance Transmission & stuff.
