I want to run a car intake and I got a ls2 intake and throttle body and was wondering if the ls2 throttle body is compatible with the factory lq4 setup?

 

Yes it will bolt on. You will need a X link controller for the TB plug to the truck plug, some fuel line work, injectors, adapters.

 

I wanted to keep everything OEM. Is there a way to do it without the xlink?

 

i think i read somewhere here some guy just rewired the TB plug onto a nnbs TB plug. I looked at some diagrams of them and it seems doable.

 

isnt there something different about how the throttle body functions are processed in the TAC module?

 

Don't think so. All i do know is that the NBS TB has 2 sets of "LO REF" wires and 2 sets of "5V Ref" wires. And the NNBS, in your case ls2, has only 1 set of each. It's somewhere in this forum I read that a guy did it, he just left those 2 unspliced or just spliced em in with the others and it worked. I can't find the thread tho..

 

what about using the corvette ls2 TAC and Gas pedal?

 

yeah that'll fix your TB plug issue, but how will that LS2 tac communicate with the lq4 pcm? Unless the plugs are the same..? which i doubt
