I am build a ls vtec motor, I just bought a head that was missing the intake mani and TB. I bought a edlerbrock intake mani and I was wanting to use my stock ls TB. Anyone know the main diff. between the grs tb and the ls tb?

 

The tumbler is different, ie the part the throttle linkage mounts up too , the GSR pulls from over the top the LS pulls from under the bottom, if you look at both you will see what I mean , other than that they are the same

 

yes you can use it..

 

thanks a lot, the search button is my friend
