Are LS1 and LT1 injectors the same?
Hey guys, I need bigger injectors, and I have a friend with 42 lb SVO's that I would like to use, do I need to modify anything to make them fit, aside from recalibrating the computer? Thanks!

No they are not the same. They are rated at a diffrent fuel pressure. LS1's pressure is higher and run at 4bar and the LT1's run at 3bar. I wish I had some more detailed info for you but i'm quoting an article in my GMHT january issue. TTT for ya. Hopefully someone has some more specific info yor you.....

You can use the 42 lber with the right tuning, they would be more like 46-48 lbs for LS-1 fuel pressure.
I'm using 30 SVO's just fine, go to LS-1tech for some formulas
