...same question?

 

Use an adapter with a stock TB. But thats not worth it.

 

will the ls3 tb hold boost? is it that the tb open oppisite way or is it that with the tbss tac the car tb doesn't open all the way. i think with the drx-link you have to cut a wire depending on what tb you are using. but if you gain 15whp with the swap then loose 10 because you use the car tb do to being boosted, then its a pointless swap. but if the ls3 tb yeilds no loss from the tbss tb and will hold the boost then thats a swap i'm willing to look into. are the runners short on this thing or longer than stock?

 

hey guys, not to hi jack the thread. but im wanting to do this swap also, however im going to buy aftermarket fuel rails and use my stock injectors. will any ls1 style rails work? and will it work with my stock injectors? i really dont want to by new injectors,and im already buying new rails. just want to know what "style rails" i need to work with the tbss intake. thanks

 

??? anybody?

 

Nice gains, congrats!

 

I have an 01 suburban DBW set up. According to the torqerush site a straight adapter harness will run the TBSS tb. Any one done this? Any idea where to get the harness?
Are the NNBS throttle bodies wired the same? Jay

 

i need to hurry up and find a good deal on a intake

 

use your current stock fuel rails, or use the ones that came with the intake. You can use return or return-less . . .

If you get the aftermarket rails, you'll have to fab your own mounts to the intake.

I did the swap on my 04, it's already a return-less fuel rail. I just reused the fuel rail that it came with, Dr X harness, and the truck TB. I did not need to get any extention harness for the MAP sensor, just open up all of the electrical tape, move it to where you want it, and then tape it back up. There's plenty of wiring already there, there was no cutting at all.

 

I'd like to see someone make a retrofit kit for the 99-02s to re-use the stock fuel rails as well as a throttle cable bracket that retains the stock geometry.
