HF's are 1819, I ran 13.90 with IHE, gutted with shitty tires. before going turbo.
I then did a full MSD ignition and drag radials but never got any times. I think mid 13's is reasonable to expect with some Mods. you will need $2,000 to 3,000 before even thinking about turboing this set up. Unless you want to hack it all up. trust me its not a matter of buying a turbo and slapping it on. there is extensive modifications (ie: stock radiator gone, stock front cross member gone). if you want to do it right. Just do little things at a time like Headers one month and maybe then Cold Air Intake the next.
