hey does anybody know if you can use the fuel injectors from off a ls1 to us with a lt1 and does anybody know what the fuel injector size is on the ls1

[96Camaro]

Yea I beleive you can. But you may need the computer tuned for it I would think.

[93*z28]

i dont think i can mess with the computer its an obd 1 not a lot you can do with that

[Trash man]

if i can mess around with burning chips for my TBI motor(88) u can tune urs. i think madz28 does a tune for u, ask steve93z(beleive thats his name) he has a warmed over 93 z i beleive

Physically, the injectors will fit. There were several sizes used in the LS1's, and most of them were 28#/HR. But that's the flow rate at 58psi used in the LS1 fuel systems. When you put them in an LT1 with its 43.5psi fuel system, they will flow just about the same as the 24#/HR injectors that were used in the 94-97 LT1's. Unfortunatley, thats about 10% larger than the 22#/HR injectors used in the 93's. The long term fuel corrections might be able to adjust for the extra flow, but its always risky, since running a larger injector than its tuned for results in the ECM pulling fuel out with the LT corrections, and when you go WOT, the ECM will default to a 128 LT correction (BLM) and it runs too rich.
