Alright Im hoping you all can help but not sure on the answers Ill get on this lol. Ive been wondering about which route to pursue performance wise. As you probably remember I have the auto tranny. I have 4-2-1 headers, cai, 2.5 exhuast with 4inch muffler, and Evo F.G hood. Im picking up Centerline Storms soon. Now the tricky part, lets say I add 70mm TB and Airram(or custom one just as good), under drive pulley, and 1.8 cam. Is it in the realm of possibilty(with a brake stand and O/D off then O/D on into 3rd) that I can hit low 15 seconds in the quarter? Id like to think so but idk. So some honest help here would really help me out and be greatly appreciated too. Thanks!

Im really just curious as to what the Tib is capable of with only N/A bolt ons.

 

if you were a MTX, u could hit 14's with good tires with those mods, but very doubtful with the auto-tragic trans.

 

Dont use the chrome wheels and it will also help the time. I think you can break 16, but IDK about low 15s (I dont drag thats just from reading from others).

 

Stick = low 15's easily

auto = high 15's, mid 15's if your lucky...

 

I'll go with Alex on this one.

70mm might be a bit big for a N/A TB. 65mm TB/Air-Ram I did lose some low-end responsiveness. In an auto when you can only brakestand to like ~2k, it'll be tough to get the car moving into the 4k+ range, especially with first being longer in autos.

 

just take a look at tdonnel's car... it's one fast n/a tib!

 

stick n/a tib tho /\

 

Im GEUSSING that Id hit low 16s now. my tranny is good(only 2000miles) 4-2-1, exhaust, intake, lighter weight parts. Im atleast hoping for lower 16's. And with all I mentioned you still dont think a time of 15.5 approx or lower is possible? Am I fighting a losing battle? lol

 

Manual = hot
Auto = lame

Auto's longer gears and more drivetrain loss kill it. I'd say you'd get mid 15s with those mods, but why pay out the butt to be as fast as a manual with I/E? I ran 15.5 I/E.

 

spend the money on a manual swap. that will be one of the biggest upgrades you can do. if you dont know how to drive stick, rent a stick car and have someone teach you in a parking lot.
