RU18YET Posted April 2, 2013 Report Share Posted April 2, 2013 I am buying TBSS intake manifold and TB for $175. It is coming with the rail and injectors. I have been trying to figure out exactly what I need to make it work and have read many different ways. 1. I will need to go to o Riley's and get an Evap purge 2. I will need a corvette fuel filter w/ regulator to use tbss fuel rail. 3. http://m.summitracin...arts/cei-108115 I believe I can use a harness like this to use the ls2 TB. It's a lot cheaper than x link and people say it works. Opinions? 4. Will the ls2 injectors plug and play? Or will I need 8 adapters?

GI.SS Posted April 2, 2013 Report Share Posted April 2, 2013 i think being you have a cable driven TB, it would be easier to use a 90mm cable driven tb and sell the tbss TB to pay for it. Quote Link to comment Share on other sites More sharing options...
RU18YET Posted April 2, 2013 Author Report Share Posted April 2, 2013 I don't have a cable TB. 78mm 8 pin just like your stock TB Quote Link to comment Share on other sites More sharing options...
GI.SS Posted April 2, 2013 Report Share Posted April 2, 2013 i honestly dont think that adapter will work and its x link only for the 8 pin to 6 pin tbss TB Quote Link to comment Share on other sites More sharing options...
zachm89 Posted April 2, 2013 Report Share Posted April 2, 2013 The TBSS injectors are a different plug than your factory truck injectors. I would just reuse your factory injectors until youre ready to upgrade to some 42# or bigger, i dont think the TBSS injectors are going to be a huge difference in actual flow numbers than the factory truck injectors. You will need the evap but not the filter and regulator unless you plan to drop the tank and remove/destroy the factory regulator on the pump assembly, it will work just fine. The dr x harness is the way to go for the wiring, I wouldnt cut any corners there as i think any other harnesses on the market wont allow the throttle blade to open to the full amount.

Thanks for all the help, I guess ill have to fork out $225 for the x link So my factory injectors will fit in the tbss intake and fuel rail? Also I've been reading about the whole returnless fuel system that the tbss's have. so I can just hook up the fuel line just like its setup now and but with the tbss rail?

zachm89 Posted April 3, 2013 Report Share Posted April 3, 2013 The install will be different between an 03 and 04 SSS so be mindful of that when swapping info. The 03 trucks had a return style fuel system, 04+ have returnless so yes, all you have to do is hook up the feed line, run the new evap solenoid off the side of the rail and use whichever injectors you want. If you use the TBSS ones like I said I think they are a different plug but not certain but yes the stock truck injectors will fit the rails. Not sure on length differences between the two, I think they are the same iirc. Only thing you might have to so is swap the o-rings. Quote Link to comment Share on other sites More sharing options...
