TBSS Intake manifold swap

Has anybody ever thought about doing this? From what i have been reading they will bolt up to the stock heads, and flow alot better than the stock truck intakes, plus they have the 90mm TB opening. And a place in dallas called ADM Performance is porting them out and picking up 10-15 horses on the port job for 200 bucks.

Im looking at swapping 243 heads and LS6 cam into my 5.3 and was thinking the TBSS intake might be an easy swap to get some more power, plus the bigger TB.

More air in=more air out and more power.

Actually: More Air In + More Air Out = More Power

I'm feeling anal today. I know what you meant. :lol:

I think Virgil is going to try this - you might check with him or I guess he may see the post. :thumb:

TMI Moze... :laugh:

What year TBSS can you use? What mods are required to do this?

You'd probably be better off having the heads worked up before going to the other intake.

i am doing this swap here in the next couple of weeks i already have the intake setup.....they are saying at least 15rwhp from the swap plus if you get the rails and injectors you get a better flowing rail and 33lb injectors......just need to buy the wiring harness adapter for the injectors and eletronic throttle body

Does the stock DBW TB on the truck use the same connector? I def think this is a worth wild mod, i was watching one on ebay that was complete minus TB and missed it at the end and didnt get my bid in, it went for 160 bucks.

Ok, well i put up a wanted thread looking for a TBSS intake setup, and got a PM about a guy that has the complete setup, manifold, fuel rail, inejctors and TB, he removed it at around 2K miles and installed the maggie.

The TBSS injectors have a different plug than the truck injectors? If so ill probably sell them and get some 8.1 injectors, that way it will be plug and play on my truck, id rather do that than cut up the harness to swap connectors. I was also under the impression that the DBW TB's all used the same harness plug, but if i have to change it, then i guess i will.

no they use a diff wire...they sell the new harness on LS1Tech.com for $189...also you would be better running the LS2 injectors...but it's your choice...there are also a few other little mods that you will have to make but they are really just vaccum lines and such

Can we get pictures when done? Can you jus swap the 5.3 injectors over to the TBSS intake if needed? For the TB can you just simply swap the connector out or do you need the swap harness?

I did a search and found this swap harness. Plug in harness for installing
LS2 intake and injectors on a LS1 motor.

awesome find!!!!

yeah and it says its only 80 bucks for the kit.

does anybody have a link to a thread listing out everything that is needed to do this swap?

Also is there anyway to get the stock vortec engine cover to go back on? Not sure how the TBSS engine cover would look, but maybe not bad if it were painted.

Also remeber that the LS1 has a different Inj. connector than the truck injectors.

you can also go to Casper's Electronics and order the injector conversion harnesses. they are 7.95 each and require no re-pinning just plug and play.

OK, it looks like another potential problem with the TBSS intake swap, is the fact that the TBSS fuel rail only has a feed, for the returnless fuel system, and on the 03 and down trucks there is a feed and return, so would using a 99-03 vette fuel filter/regulator assembly solve this problem?

The you would just need to run a new feed line. Also the above wiring kit wont work on the 03+ trucks, but you can go to LS2, LS7, 90mm throttle body to GM truck or Holden electronic throttle LS1 adapter harness and they have the x-link 2.0 that is plug and play and works with the stock 03+ truck pedal and TA module, and you dont have to cut the harness.

cool. so on 03 + trucks that use a returnless fuel system this swap will be even easier.

Its 2004+. as my 03 has both lines on the rail.

i think the guys on the TBSS forum are a bunch of morans. I posted a topic over there asking for an intake manifold and everyone wants to sell me their airbox. even after i posted saying i want the manifold that bolts to the heads and has the injectors mounted to it people are still wanting to know if i mean the airbox

Not sure about that, i put up a post looking for a complete TBSS intake manifold with injectors and rails and TB and within a few hours got a PM from a guy that has a maggie on his TBSS and was about to put the stock stuff up on ebay.

With grammatical errors like that, it's no wonder you didn't get what you asked for...

yeah right hit man my wife who is an english teacher and knows NOTHING about cars understood that i was not looking for an airbox. sorry i did not use the gramer book to post. you must have been one of the guys over there posting up pics of the intake tube or asking me to buy the stock airbox for $150

Has anyone done this swap yet? any pics?

bump...
