stock ls1 w/ stall converter
I'd go with Fuddle. You can't beat their service or pricing.
I got a Performance Series 4000 stall with 2.2 STR for $400 shipped. They don't have that deal anymore and now its $400+shipping
With full bolt ons--those being LT headers, ORY, LS6 intake and lid, underdrive pulley, 3.73 gears and a good stall converter-- I have seen A4s in the 11s with sticky tires.
If you go with Fuddle, the money you save could get you a set of 3.73s or some headers or something. You can find pretty good deals in the "For Sale" section on headers and intakes, but I'd get a new converter. Good luck and have fun!
EDIT: Definately do a tranny cooler with the stall install!
I went from 13.5s to 12.5s by just adding a Yank 4000 and a set of M/T ET Streets. Had a lid also. Everything else was stock. Added Headers and true duals, dropped to 12.2s and picked up 4 mph. Add a 100 shot, 11.3s!!! Converter should be one of the first mods you do.
