hey i was wondering, i want to get some better throttle body setup, buit im not sure how to go about doing it. iknow for the lt1s you can by the 52mm TBs compared to the 48mm stock, but i dont know about on the L03s, so any suggestions on cheap ways to upgrade in any way??

 

Several individuals and companies will port/polish and even bore out your stock TBI for a fair price. Or you could do those yourself.
(See Ultimate TBI mods)

You could also look into
a TBI with 2" bores from a BBC or an aftermaket unit from Holley.

They sell on Ebay all the time
thirdgen's classified section is a good source as well

The TBI unit is not really the biggest bottle neck on the car.

 

For an L03 I would simply suggest the ultimate tbi mods.

 

im not familiar with these "Ultimate TBI mods" stuff, can anyone educate me?

It's all in the tech articles. Do a search too. Much can be learned that way.

 

how much hp gains will i get? how much better with these mods help my throttle body?? is there any hp or tourque gains?

 

Yes you will see a gain. How much, i have no idea. Just do a search. It's been covered A LOT before!
