So is a tbss intake the same thing as a nnbs intake?

 

id cut the stock rail and flare it, worked fine for me and was cheaper.

 

tbss and nnbs intakes are the exact same yes

 

Use your Current Injectors, put them in the tbss fuel rail, and connect the vette filter and regulator to the rail.

 

 

im running nnbs intake. i had my cousin cut the inlet tube on the nnbs rails and make angle cuts on the pieces and weld it back so it raised it up about 1" and ended up being a few inches shorter, and then welded the flared piece back onto the end. it didnt cost me anything and looks better IMO. i also had him weld a nut on to the side of the rail and i bolted the filter/regulator to the rail.

and id drove home from where we did the cam/heads/intake swap and then 40 min to the tuner the next day. but i wouldnt reccomend it if you can avoid it. it was running rich and difficult to keep running. after the tune, its awesome.

 

Will the Tbss intake not bolt right in?

 

it will bolt right in just like the nnbs intake, but nnbs intake is everywhere so much easier to find. I got mine for $150 bare. Now they can be had for like $120 bare or like $250 complete.

if 03-06, the fuel rails are returnless and the intake will be basically plug and play depending on which injectors/tb you use.

if 99-02, you have to either modify stock rails to fit the new intake or use the vette filter/regulator to convert it to returnless.

 

What kind of gains have you seen? Is this a 5.3?

 

SWEET!!! I have an 03 and for some reason I got it in my head that I was going to have to modify/change my fuel rails. So all I should have to do is change the purge solenoid and map sensor?
