Need to go over injectors and what you need
Excellent little video
Do more Silverado upgrades please great video by the way keep it up
Great video! To add Glenns auto performance makes an absolutely beautiful and affordable drive by cable throttle linkage adapter for the tbss manifold. Highly rec.
Great video
I got a 2006 Canyon that originally came with a Returnless Fuel system So running a Returnless system is a breeze. Gotta love when the regulator is built mechanically in the fuel pump. I also have a NNBS intake and it has a hard nipple for the PCV.
Literally used that exact bracket and throttle body on my swap. (2001 Silverado 1500 with an LQ4/80E swap) The only issue I encountered was that my cruise cable has too much slack. I solved it by crimping a lead fishing weight on the cable. For the fuel line, I used a C5 Corvette fuel tank transfer hose with the C5 fuel filter. It is plug and play, looks factory, and keeps the fuel lines from being up against the firewall. I am 4 years and about 25K miles on intake swap with no issues.
Awesome! Yes the C5 filter is a common part we recommend for swaps like this. Keeps things tidy as well.
@@Sdpartscenter - I need to upload a walk around video of mine. Most people do not realize that I swapped intakes. The NW throttle body is about all they notice right away.
Thank You ! Tech To Know
Good stuff..
Video Request: What LS7 parts (+ other parts) will fit a Dart LS Next 454? Lifters, heads, etc. to finish a Dart LS Next 454 shortblock.
I broke mine plug that's where I got leak thank you
I like torque and if I gain some horse-ponies so be it. A daily driver is not going to see 6k or 7k RPM everyday or perhaps ever. Has anyone tried to more with the truck intake other than shave it to look pretty. Has anyone cut the cone out of the center near the Throttle Body that forces air to the center first, before this air is dispersed front and rear? Some clean up and porting can be done to match the ports better and have some positive results. Now aftermarket intakes do away with this centering tube. Working on V6 imports, some incorporate a vacuum valve to change from long air stacking to short air flow at 3,200 RPM’s.
With that, the budget minded guy/gal who spent their retirement putting 3-4 kids thru college. As an ASE master tech since 1978, I’ve seen Nissan place an intake gasket with a counter-clockwise triangle in the port to increase low pressure rotation to help complete combustion burning and performance. Both may have benefits as we both know from the 50’s how air in motion, stacks up behind a closed intake, but a straight line is much better for high RPM. I saw this on the highly modified Corvette with carbon fiber bell shaped ends and a throttle valve inside each carbon fiber intake tube. They designed it to synchronized with 4 left and then to 4 right. Cable driven at one location of course, but a red-line starting at 9k on the dashboards tach. I find it interesting of what people & engineers come up with.
Like the famous “Smokey Yunick”, velocity stacks, volumetric efficiency, etc., a tough B-17 bomber pilot who in the 50’s stirred the imagination of thousands of back yard mechanics, only to have son’s who build engines with more horse-ponies than the other guy who gathered pink slips...from car owners. Truck intakes maybe ugly, but still have a place in the “LS” world. Also 2003 utilities had DBW instead of cable but small & 3 bolt. Enjoy learning!!!
Great info! Where does the feed tube come from that hooks to top of 92mm TB?
2006 Silverado 1500 with the LQ9. Looking for a factory crate replacement if at all possible. Does this come in a short block only setup, or next question, I would think the cathedral style port heads will bolt up to this block the same as the original. Really what I want is a factory crate LQ9 replacement. Great videos, thank you all very much.
Yes I have been working on putting a 5.3 into a 94 Silverado. I cut the windshield side of the dash to fit and took an inch out of it to bring the door sides of the dash in closer.so I have an 02 dash in the 94 I'm currently removing the cab harness and fuse panels to put inside. I have the power mirrors installed. The dash is also wider so I'm using some billet aluminum for door panells. My question is what all will it take to make the instrument cluster work. I have everything from the donor truck... Also I'm running a 350 turbo behind the 5.3 that's built. Wanting to keep fuel injection and put two small turbos with can and tune it. What would I need for 3.73 gears 275x60/15 drag radials to get in 6s 1/8 mile and be streetable.?????
What problem did you have using the factory o ring from the newer style map on the earlier map sensor? I used this o ring on my swap and had no issues yet and have put over 20000 miles on it so far. I know I had to grid on the map sensor retainer.
I am working with the intake manifold from an LFA, it appears to be the same as the TBSS or "NNBS" and haven't found anything to suggest that it is a different part. It seems to have a second map sensor though, it is on the side right behind the throttle body. Any ideas on what it really is? Or any nail in the coffin against using this LFA manifold altogether?
Like the info I want to put a 09 5.3 intake and I have everything however what about using the newer 08 injectors do I need a special harness or pigtails again
When you speak about doing the custom tuning to adapt all of the signals between the six and eight pin plugs will the truck still be drivable? My tuner is a little ways away just wondering if I'm going to have to plan to trailer it there or if there will be damage done if I drive it.
I have trailblazer intake and xlink I always throw p1516 code reduced power. Went back to stock throttle and still does it not as much. Could I have 2 bad throttle bodies. I really like performance with ls2 throttle
NO=ow that was a good video and Im not easily impressed. Straight to the the points, hit all pros and cons. Explained everything good even for the less knowledge engine people. Toss in a few plugs for parts and done. Very nice!!!
Hello i have a 03 5.3 silverado im getting the crate engine ls364/450 and im gona mount the ls3 intake manifold on it i already bought ev1 to ev6 fuel injector adapters and rn im looking for the x link but i dont know if i need a gold or silver and also i need help with the MAP sensor how would i go about that
Were did you get the throttle cable bracket and does it have provision for cruise control?
What do we do for the radiator hoses that run under throttle body? I have the new one and it doesn’t have the connections
What about the Dorman Chevy Avalanche part # 615-183 intake onto a 2002 5.3? I really like the looks of those stock intakes, Could I just buy the Cathedral port to square port adapter? And convert from return to returnless and convert to DBC?
Plus I have the two fuel lines on my 03 classic weird hey not the single fuel line
It is a LS Gen 4 Intake
My 2004 Suburban has a return style fuel rail from the factory.
Must be a early 2004.
Is 2011 GMC Sierra 5.3 intake manifold is the same as a trailblazer SS intake manifold
What about the other port on other valve cover
👌🏿👌🏿
So I have a tbss intake band the manifold in rectangle and he told me this.
Bro that manifold won’t work unless your lq9 has rectangle ls3 style hesds
I got a gen 3 ls 2004 is it a 1q9 or lq4
I showed him pictures of the heads same heads (6.0ls) and he told they won’t fit cause there cathedral and that my manifold is rectangle and he told me they won’t work I just wanted my tbss intake to get ported all the way and a new throttle body someone help me
Fuel mileage? Smog? 0-60?
Swapping a 5.3 in a 1995 S10 that came with a 2.2.. Will I have hood clearance issues with the SS Trailblazer intake ? Also considering a F.A.S.T intake , but don't know which one will work so hood clearance won't be an issue. Donner truck engine is a 2006 Yukon along with it's 4L60E transmission.
👋👋
Hi, thanks for this super informative video. I'm in the process of swapping a TBSS / NNBS intake manifold on my 04 Tahoe Z71 ( flex fuel equipped with Z on 8th digit of the VIN# ), i got the manifold with fuel rails already but still need to buy the injectors and throttle body so i have few questions for you, if you don't mind, what's the price on your X-Link harness and where i can buy it? also will your X-Link harness work with an after market throttle bodies too or only OEM ones?? what's the larger diameter throttle i can use? and last but not least since i now have flex fuel system do i have to buy the injector adapters to be able to use the bigger TBSS injectors or must use my current ones?? Thank you very much in advance
You can use the flex fuel injectors on your truck as they will fit those rails.
92mm is the biggest you can go on the TBSS/NBSS intake. And since the X-link only works with OEM or NW throttle bodies, using the stock 07-13 gold blade throttle body is what you will need with a gold blade X-link.
@@Sdpartscenter sweet and thanks for your response, can you please provide me a link or part number so i can go ahead and order the X-Link
@@Sdpartscenter alright i already got the X-link from you at summit racing ( gold for the new OEM LS3 90mm throttle body i got ) and since my Tahoe has return fuel system i also bought the C5 vette fuel filter/regulator but now i'm having a problem because i hooked up the vette filter to the tbss ( return less ) rail but now my both ( feed & return ) factory hoses are kinked against the fire wall because the filter is way to back on the tbss rail so i was thinking in modify the rail inlet by shorten it so the filter location will be closer to the crossover port so my factory hoses will connect to the feed & return lines on the filter without getting kinked back there, i really would love to hear your opinion about this i want to do or maybe you can suggest me something different to solve that issue i'm having, thanks again
just sent you pictures to your instagram of the progress on my TBSS/NNBS intake swap
Does the x link come with the tuning data needed to convert the dbw ? I lready have everything to do the swap besides the xlink .. heard mixed reviews on it
Your tuner will absolutely need to be experienced with installing and using an XLINK, They do not come with a how-to on the tuning for them.
Strange. Could have sworn "Richard Holdener" also dyno tested this and it made more power on a stock 5.3
Just what we'd found while testing.
¯\_(ツ)_/¯
Here's the TBSS intake with larger throttle body, graph overlaid over the stock 5.3L run in the same video:
czcams.com/video/rzzGidbDhvY/video.html
Richard is one of the most well educated and proficient tuners of all time. His lawn mower prolly makes an extra 100 hp. I do appreciate the hard work SDPC puts in.
I have a 2002 yukon denali 6.0. And my yukon came with dbw throttle body not cable driven. And I have tbss intake on it. I was told that I need a silver blade TB and the xlink adapter won't work. Because the 2002 use a different TB ,tac module ,pedal assembly and pcm calibration . And that a straight adapter harnesses should be good enough. Have you run into any thing like this. Or may be is something you guys can look into and see what I can do to use a 90mm or 92mm on yukon.
Sorry we do not offer a solution for the early drive by wire trucks and SUV's.
I have a 03 with a 4.8 motor. What kind of performance build can I do to make it an everyday commute plus off road or drag?
Truck Norris Cam with . 560" lift springs, turbo, no need to use this intake.
I have HP tuners. What additional tunning were you referring to for when you adapt the throttle body and x-link adapter?
I've never heard of any in my internet travels, supposedly plug and play
@@Diabloshell I've been watching a lot of tuning videos lately and I think in order for you to get the optimal performance, anytime you change something on the intake, it helps if you tune your Mass Air and just make sure your AFR is happy
But ya, it'll run after installing
I've added 2 of them so far
Does the tbss intake pick up any power on a bolt on a 6.0 lq4 2500hd?
Especially in the 200-3500 rpm range.
I’m getting ready to do this. What did you find out?
@@Motoxr32 i haven't did it yet. But it looks like the tbss intake is the way to go.
What "custom" tuning needs to be done if you use the x-link?
Some of the ETC parameters will need to be adjusted, other portions of the tune will need to be optimized for improved aiflow including your MAF tables. There might be some documentation on the HPTuners forums, but it's something that's best performed by an experienced tuner.
For those of us with a return style fuel system, do we have to modify the fuel rail to make the filter fit with the stock fuel lines or will it all connect easily without kinking the fuel lines???
You'll have to convert the fuel lines on the chassis to returnless. Most people use our fuel filter kit, some fab/assembly required.
Filter kit: sdparts.com/i-24498808
Video on that product: czcams.com/video/G_yI175P9h4/video.html
Scoggin-Dickey Parts Center won’t the fuel filter on the rail push the factor fuel lines back against the firewall? Won’t kinking the fuel lines be a bad thing?
Corvette filter/regulator for 59. Or buy a fuel reg with 3 ports. Ive ran both. Did not see a difference under 500hp
So you say older style trucks. But what does it do for 2008 5.3 Silverado. Truck intake on 2008 is as good or is the trailblazer SS 2009 better
Nnbs and tbss intakes are the same. You already have this on your 2008. A ported version will give you up to 18 hp more on a heads/cam application. Chuy's porting and polishing has proof and has them available to buy.
For us throttle by cable guys what do we do with the old coolant hoses that run under the stock throttle body
I just did mine last week what I did is I got a 1/4 hose barb connection and passed it over it it’s okay to do that if your not in places where it gets real cold since that hose line passes hot coolant thru the intake and you don’t want hot air but I’m in Texas haven’t seen real cold weather yet lol
Thats just there to heat up the throttle body. So its useless and can just be bypassed with a barb fitting.
06 here, so if my original old style fuel rail wont bolt on, what do i do? I have the tbss rail also. Do i swap injectors? As the plugs are different, i cant use tbss injectors?
Swap the fuel rail over, you can use the original injectors. Be sure not to pinch/cut the o-rings on the injectors. The TBSS injectors can be used but you have to either change connectors or use an adapter plug (Casper's electronics has some of these components). You will also have to change your injector tables to the TBSS injectors while making changes to your tune.
@@Sdpartscenter according to the seller they are 36lb ev6 and i have 36lb ev1 ? Either way, i probably wont reuse either set. The tbss ones are really dirty. So are you saying to swap my original rail on the tbss? Will that require any modifying physically? And it would simplify the tuning portion
@@Sdpartscenter in the process of doing this on a 2003 gmc denali suv but the denali has a a return line what u guys offer for that?
@@ManuelGarcia-cb3lw corvette fuel pressure regulator
So I have a 89 gmc c1500 would I need to get the c5 corvette filter and regulator???
If you are doing an LS swap, yes it'll work great!
Is their a part number for the pcv at the top of the intake??
It's just a hose connection that's part of the intake itself.
Will this work on a 2008 5.3 Silverado Flex Fuel? @Scoggin-Dickey Parts Center
Yours came factory with this intake.
@@Sdpartscenter SWEET Thanks!
This a good upgrade for a 02 5.3? What part #
Parts are linked in the description above.
It's a good supporting mod if you plan on doing headers and/or a cam as shown in our dyno video:
czcams.com/video/rzzGidbDhvY/video.html
04 4.8 here does it requires tuning what's needed I'm on a very tight budget to none just want my engine looking better than the old ugly on lol
If you change the throttle body size or different map sensors, most definitely.
@@Sdpartscenter um what's the difference if not changing anything other than jus the intake I think stock injectors are 26pounds per hr and also map sensor I'd have to change that out ? and isn't the map sensor on the tbss on the bk instead the top like my original on is ?
@@Sdpartscenter I was thinking keeping the same throttle body and map sensor also should I delete the EVAP
Can you give me the part number for the wire throttle body connector I need one for my build
You mean this part?

I Just want to get away from the fly by wire throttle body in my 04 5.3 vortec
This applies to the vortec 8100 too, right?
Sorry, the 8100 is it's own animal. For that it's either factory intake or a pricey one-off piece from somebody like Raylar Engineering, they do offer modified stock intakes that have the internals trimmed and opened up a smidge.
@@Sdpartscenter That's what I thought... Thanks for the prompt reply! I have been eyeing Raylar products. Looking to exhaust all options. Although, the ol' 8.1 doesn't have much support. Have a good day.
Can you use the same injectors?
You can, but they'll usually be at the limit for any other mods. Just keep an eye on your injector duty cycle with the tuning. Most will swap over to the TBSS injectors or something off the flex fuel trucks. Some will require an adapter or re-pin the connectors.
Make sure you use the right injector data!
Scoggin-dickey sounds like a Borderlands bandit clan name
Thankfully no meat bicycles here haha.
will this work on an 08 5.3 suburban?
Yours is an NNBS, so it won't be an improvement as you technically have the TBSS intake installed so you're already starting at a good point.
You have the gen 4 LS truck intake already, you don't need to touch it. Yours is GMT900
The upgrade is for LM7/LR4/LQ4/9 trucks or GMT800 1999-2007.
whats the part number on the throttle?
i have a 02 Silverado whit return fuel line
SD92MM, but we are currently out of stock. Some vendors might still have one in their inventory as we supply these throttle bodies to multiple companies.
sdparts.com/i-22676170
No one cares or likes electric powered throttle body . Those are horrible!!! I would never want a computer controlling how much of the butterfly trap can open up.. I rather have control manually with the gas pedal a wired throttle body is better then advanced.. because the computer won't ever be as accurate
