So I've been lurking here for awhile, but haven't really posted. I'm collecting parts for a turbo build on a 2013 Suburban 5.3L LC9. Not looking to make crazy power, just low 400's, and keep it street reliable. Anyway, been searching and can't find clear info on what injectors will work...

I think LS2 style injectors or LS3/7 injectors with Fast spacers will both work but read this post and seemed like there was a difference in length between LS2 and "truck" injectors.

Anybody know if these will be plug and play? Or what are my other options?

New to alot of this, but based on some calculator I found, think I could use 42# LS3 injectors. Would need 60# if I wanted to push it further, but doubt I will at this point with the stock engine and tranny.

My stockers flow 32#, what's the max anyone pushed with these?

Thanks for all the great info here

It will be pretty easy to push past your low 400's goal, I'd think you can still make 450-500 easy on low boost still.

The stock injectors won't be enough that's for sure but if it's a flex fuel pump you should be alright to around 500.

I'd look at these, they are direct drop in units.

Appreciate the link. I do have flex fuel, so think my pump will be fine for my current goals. Questions about the LS2/LS3 injectors come from the fact that I can pick some up relatively inexpensive from the corvette forums (less than $300) so if they are plug-n-play, was considering going that route until I decide to push the build further.
