Default Tbss on L33

I have a 2005 L33 with a Z06 cam and was t thinking of swapping the stock intake for a tbss intake. Researched it and it seems I even if I use the tbss throttle body I will need a tb link that cost about $250 even though both throttle bodies are dbw? Link and tbss with tb $400 plus some other incidentals, don't know if its worth it for a small gain in hp?

They are both DBW, but completely different.

I would go ahead and put the intake on and get a cheap adapter to use your stock throttle body until you can find an affordable option.

After doing some research it looks like I wouldn't gain more than about 10 hp on a mild 5.3 build like mine. I think the money would be better spent on good limited slip unit. Maybe a manifold swap later...thanks for your input.

Yes there are many dyno results showing that the net gain for swapping over to the NBSS/TBSS intake manifold is not worth what it will cost you to swap over to it. I think for highly modified engines, everyone is going the FAST route. If I were going to invest in an intake swap, it would be ONLY the FAST, or the Dorman intake that has now copyrighted the early FAST intakes.

How much do you think it costs to swap over? Even if it costs half of a FAST intake for the complete swap, it gains more than half of the overall power/torque.
