Sup guys? Just sitting here going through the forum and suddenly was curious about something. Im not real familiar about what parts swap to what but I was wondering about this! I have a 04 ccsb that I am putting a lq4 in and I am putting a tbss intake on it...! Question is...is there a 90mm throttle body that will plug into my truck? I have a machined adapter that will bolt a 3 bolt throttle body to a 4 bolt throttle body intake if needed...and if needed...yes my truck is DBW...hope for some good feedback...thanks!

 

the LS3 Throttle body will work. you will also need a Dr. x harness to control the TB. Have a read through this thread. Has lots of great info.

Damn I love it when there is proof! So big question is where do I locate this x harness?

 

Just google it.
Torque Rush LS2, LS7, LS3 to LS1 throttle body adapter harness

 

Just run the new truck TB, some call it a 90, it's an 87mm. No reason for an adapter plate, but still need the x-link.

 

x-link is like 220 i think

 

just bought mine 237 shipped
