Can anyone confirm this?

Curious if the HPFP and injectors are larger on the LT1 than the 5.3L/L83 ones of if they are the same.

Thanks!

 

If you'e talkjing about the camaro or corvette motor then yes

 

I am referring to the 16+ Camaro and 14+ Corvette...

And when you say "yes" - do you mean yes - it's bigger? or yes they're the same?

 

yes as in more flow I'm going to upgrade to the lt4 pump and injectors

 

99% sure the pump is the same and the injectors are larger from L83 to L86. Lt4 are larger on both still.

 

If this is true then it's true that the LT1 injectors/pump are the same as the L83 - (as it's been confirmed elsewhere that L86 and LT1 are the same) - Which makes sense since the L86/L83/LT1 are the bulk motors (so it's cheaper to make the pump/injectors all the same) and the LT4 is lower volume so that'd be the only one getting an upgrade.

Just gotta find out about the in-tank pumps now

 

LT1/L83/L86 HPFP are the same.

As for injectors

L86 118.7lbs
L83 96.5
LT1 corvette 121.1
C7Z06 140.7

not sure on in tank pump

 

This is awesome info!
Where did you get this? Jw

 

How did those injectors end up working for U I’m having some issues with my truck injectors and wanna put some LT4 injectors did you have to tune the truck after or change the high pressure fuel pump or even the one on the gas tank??
