I know its been covered but I just want to double check so I have everything in order. Just a few questions about using a NNBS/TBSS intake on the Lq4 im building to go into my 99 NBS. What do I do about the fuel rails since im return style? I know I can but a aftermarket DBC throttle body. What about sensors? Do mine swap over or should I find an intake with them already? Injectors will go off of what the fuel rail is? Probably have to get pigtails for them to hook up to my older wiring?

I see I can run a vette regulator to keep the return style.

Ive heard that both of them flow very similar besides a few differences like PVC placement and all. Any concerns about the hookup from the vacuum booster? Thanks guys

 

When I did mine I had the matching harness so I cut the EV1 connectors off and soldered them on to my exsiting harness, used the corvette filter right on the end of the rail, installed an xlink(dbw), repositioned a few wires for sensors (used the ones from my engine), and ran a pcv line to the airbox. Everything was pretty straight forward, once to get it in place you'll see.

 

Thanks. That vette regulator/filter seems to be the way to go. Does that mean I can get rid of my filter under the truck? Reason I ask is its a rusty piece of **** and i need to replace part of that line and it would be much easier to not put a filter back in there.

 

Ya, you'll just have to modify the lines a little more, not a big deal.

 

good deal. Intake and TB should be here next week. Almost tempted to throw it on the 6.0 in the tahoe to see if I can notice a difference
