i am wondering for a stock bottom end engine and a H/C swap what size injectors should i use for the lsx intake w/ 90 mm TB?? this car is a daily driver also..

 

are you using the existing heads and cam in your sig?
you might be able to keep the stockers, since they are good up to about 450rwh
so unless your making more then that
if you are you could use 30lb'ers

 

i would use the same heads but just change the cam...

 

ya you should be find with the stockers. there is plenty of 10 second cars with the stock injectors and since you already got an 02, you already got the bigger ones. if you plan on useing a dry kit with this, i would reqemend some 30s or 32s but no bigger or you will have some tunning issues.
