We need a sticky for this! lol. If your truck is a 2003 you HAVE to convert your fuel system to a returnless setup using the corvette fuel filter if you use the TBSS/NNBS fuel rail. 04+ trucks all have the return-less fuel system already. You WILL need to modify your stock crossover on your fuel rail or use the TBSS/NNBS rail. I was fortunate enough to know a friend with a TBSS and got the TB, Intake, Fuel Rail, and Injectors(30#) from his TBSS for $100 which was a steal. Then you WILL need an X-Link adapter, there is no way around it, $227 after paypal fees. If you use the TBSS injectors you will need injector adapters. mini delphi to ev6. Your stock injectors will work on the TBSS/NNBS fuel rail. You can purchase the evap at o reilys for $15. There is no difference between the NNBS and TBSS intake. The Newer(09+) NNBS truck have a different style throttle body but all TBSS and NNBS throttle bodies are 87mm. I ported mine and will let yall know the gains of the swap after its installed and retuned which will probably be this weekend.

 

recap:

(03 only) corvette fuel filter $40

TBSS TB andTBSS Intake $200ish

X-Link $227

Evap $15

retune

 

any other questions just ask

Maybe because i havent gotten under the hood for this yet, but from what i see, the stock 03 fuel rails have two lines, the tbss rails have just the one. If the "fix" is just the 2003 vette fuel filter...doesnt that have 1 in and 2 out? Or is that 2 in and 1 out? I'm trying to understand this setup before i start the conversion.
