2000 LS1 Injectors??? HELP! anybody REALLY know what the hell size the fuel injectors are for a 2000 Z-28 ??? I searched the net and found this FINALLY... after 2 days...
'98 Chevy LS1 25.2lb/hr @ 58.0psi (Part no. 12533952)
'99-'00 Chevy LS1 26.2lb/hr @ 58.0psi (Part no. 12456154)
'01-'02 Chevy LS1/LS6 28.6lb/hr @ 58.0psi (Part no. 12482704)
Some local guys seem to have info that says the 2000's come with 22# injectors.
Also what is the stock base fuel pressure for the LS1?
any help is appreciated... i need to figure out my fueling situation!!!

Re: 2000 LS1 Injectors??? HELP! This is directly from my Stock 2000 PCM's fuel injection scale.
At atmospheric pressure:
3.33 g/s
3.33 g/s = .0073414 lb/s (because 1 lb = 453 g)
.0073414 lb/s * 3600 s/hr = 26.4 lb/hr
So 2000 Cars have 26.4 lb/hr injectors
This is directly from a Stock 1998 PCM's fuel injection scale.
At atmospheric pressure:
3.62 g/s
3.62 g/s = .0079807 lb/s
.0079807 lb/s * 3600 s/hr = 28.7 lb/hr
So 1998 Cars have 28.7 lb/hr injectors
All F-body LS1's are designed to maintain 4 bar fuel pressure. 4 bar fuel pressure converts to 58.015 psi.
