ls2 injectors in ls1 manifold question Got a great deal on a set of ls2 88lb’ers and need to fit them into my current ls1 manifold and rail. I know i need top spacers but ive been told the bottom o-ring will not work. Anyone know the size or where i can get the o-rings for injector to manifold?

I did but those are for the tops which are the same size. The bottoms differ in size, i know fic has a conversion kit but its like 120 bucks and comes with the connector adapters as well. I dont need all of that cause im running microsquirt.

If you call FIC they will sell you just the o rings. They won't charge your for the whole kit. I got my top hat adapters and o rings from them. They were extremely helpful. It worked perfect on my ls6 intake, which is the same as the ls1 if I'm not mistaken

The LS1 and LS6 intakes are NOT the same. In fact the LS6 intake is a common upgrade for the LS1. Later LS1's have the LS6 intake standard.

Oh OK. The wording made it look like he was talking about the manifolds. My bad!

Bottom O-ring on LS2 I believe is 14mm just like LS1. The LS3s have the 11mm o-ring.
Don't quote me on that. I've got so many damn injectors in bags around here, I don't know which ones originally came with what o-rings. But that's what I recall. I had to swap them off the LS3s but not the LS2s.
Also, for anyone wondering...
LS1 = 60mm injectors
LS2 = 48mm
LS3 = 34mm
Buy your adapters based on the original height needed minus whatever injector you have.
