i have a tbss intake for my o1 sierra nbs. i need it to be dbc does any one know if them ebay 92mm tb are any good and will a 92mm fit a tbss intake if not then what tb do i need to get.

 

Nick Williams, FAST and more. I just installed the TBSS intake last week and went with a 90mm Holly. It is around $400

 

They do come up on here sometimes but u can try LS1tech.com they come up over there a lot. I have a edelbrock 90mm DBC . So that's another brand you can look for

 

The Nick williams 92mm tb doesn't cover the seal entirely on the TBSS intakes. I will either try running the Nick Williams one I have since it seems that it might cover barely enough to seal it or get the edelbrock one because it comes with new TPS sensor and IAC sensor.
