I wanted to know if a bigger tb is better or stock is better for my setup. Right now I have the stock tb on but i wanted to know if I got a bigger one will that be too big or will it be the same as stock.


This is my setup...
b18cr....
stock bottom end
mild port
stock valves with ti retainer with 85 lbs dual springs
Skunk2 pro1 camhaft with edlebrock cam gears
aebs intake manifold
undecided on headers (dc sports 4-1 race header or something similar to hytech big tube header)

 

Stock is fine. There are other areas that can be upgraded before you'll need to look at the TB.

 

will I am going to put on some 450 dsm injectors too.. Wouldn't I need more air flow for the injectors...

 

No, you would need a tune.
