I was trying to see if anyone has used the 03 cobra 39#injectors in an ls1 car with success!

 

You don't want to use these on an LS1. They spray in a 'V' pattern instead of a cone shape like and LS1 injector. These spray in a 'V' shape because the Cobra motors are 4 valve and the injector must feed both intake runners.

 

Sheit: Are you sure? I just bought a set of 36# off ebay from a 96 Cobra.

 

96 cobras has 24# injector stock, so the 36's are most likely not stock for the 4 valve heads.

Just talked to seller. They are not SVO/Motorsport injectors. I should be OK.

 

I have been running the 39# cobra injectors for a few months and they seem to work fine.

 

You could try looking up stock turbo Eagle talon and Eclipse Injectors. 450cc from those, which = 42 lb/hr. They are low impedance too.

 

They will work, just not the good to run on a two valve motor. The spray pattern is a dual cone that aims the fuel at the intake port walls instead of on the back of the intake valve. Spraying fuel on the port walls causes fuel suspension problems that causes fuel puddling in the port.

 

Thanks for the info, I'll stay away from those injectors.
