Need help with my 5.3 to lq9 swap
#43
I live in California so they are quite strict, so what would I do if the new motor doesn't have it? Should I be fine just using the intake from the new motor or would I get a check engine lite because it's not plugged in?

Newer fuel rail is most likely a returnless and will not work.
Injectors will most likely flow the same so you wouldn't gain anything. You probably tear the o-rings taking them out too.

Yes, would need to reuse the exhaust manifolds or find shorty headers with the provision that are CARB legal. There a waist though...

I beg to differ on the fuel rail, the returnless will work, ask me how??!! Vette filter with built in FPR, wix makes one i think i paid about $20 for...
8.1 marine injectors probably best way to go, if the fuel rail is retunless and/or flex fuel the injectors are usually slightly higher flow rate, at least thats my understanding....

It won't work in CA.
Long Tube's are not CARB approved. You can not move the Catalytic converters from the factory location. You also can not delete them either. If they look like they have been replaced, they will look for the number on the Catalytic convert to make sure its 50 State legal.
Now that being said, They have no Idea if the EGR is functional or not as they do not test it. I had mine turned off along with the Air injection. I got tired of replacing the Air injection valves at $50 a pop. That system only works on start up and the EGR rarely turned on due to the speed limits and my Driving habits any way... Both Items were virtually useless.
His vehicle was built with it and if its not there you will fail the visual. It's already been recorded in the system as having them. If another station says they are not there, Inspectors will show up at the station to find out what happened. Then they will Flag his truck in the system and could possibly bring him in for another inspection or suspend his registration.
The 8.1 and the flex fuel injectors have higher flow rates. But The flex fuel ones have a different connector. I believe it is an EV6 Vs. the Mini Delphi connector on the regular trucks. If you need them, Get them. A tuner can change the flow data and tune accordingly.
