Can get a complete NNBS Flex Fuel intake complete for the cheap, and wanting to put it on my 05 5.3. I know I need a Xlink, but will I run into any other problems with it being a flex fuel intake/injectors?

 

I've seen complete intakes for around 250-350 depending how new , what injectors and what it comes with . A option is use the lInk I posted about a brand we TBSS intake bare for 95$ and piece the rest together . There's a good chance u will come under the 300 mark and at least the intake itself will be brand new just a thought

 

Yeah the intake I found is 100% complete, just wanting to know what's the typical problems to look out for.

 

Just so I understand the question, you currently have a non-Flex Fuel vehicle and you're trying to convert it to use Flex Fuel?

 

I think the injectors are the 32-34 lbs flex fuel type so they should be good for a little while but if you start playing with the fuel trims or get another cam that drinks more fuel then maybe bigger injectors. I went with the marine 8.1 44 lbs injectors to give me a little room to grow but I'm going with 243 heads and a cam with more lift.

 

My engine is not flex fuel, but the intake is. Would that be a problem?

 

Btw, I'm not converting to flex, just wanting to use the intake

 

You will need to deal with the EVAP and retuning for the bigger injectors... thats pretty much it.

 

Soon as my LS1 is assembled and installed I'm going to start a thread for 04-07 Classic since there is a million ideas and not really any definitive instructions. So far I know that the evap connector does plug into the NNBS evap, and the correct evap lines for the NNBS do fit on the 04-07 classic and are pretty cheap. You need to change the injector connectors or buy adapters for the EV6 injectors, I plan on chaging my connectors for a cleaner look.

 

Thanks for the help guys
