TBI performance mods

I just bought a 91 TBI RS with 29k original miles. I would like to know what are some basic mods to get the car into the high 14s or possibly mid 14s without NOS. I have to be able to beat the Rice and high 14s is faster than 99.99% of them.Thanks

Scan the past boards, check out the tech section and read/do the ultimate tbi mods.

ultimate tbi inc. open element filter, intake, headers, catback, 3.73 or 3.42 rearendgears.

custom chip will be needed after you do this to get it running at its best.

That should do ya. Brands, check the boards.

Just out of curiosity, wadya pay. If its ok to ask.

I made a little site that has all the mods I did and how I liked them and what was worth it and what wasn't. Take a look.
