Trying to get the LS1 "style" injectors into an LS2 intake. I have the fuel rails setup, but either need special o-rings OR sleeves for the injector bosses in the intake.

If anybody has the fix, please let me know ASAP!

Thanks

I 'll take this one Dave,
The LS2 injector 0-rings are the right od but the LS1 injector is smaller id so the injectors flop around in the LS2 manifold injector ports. Been there.

Yes, I too have tried that approach, that is why I posted here. LS2 o-rings DO NOT WORK on LS1 injectors, waaayyyy too loose.

I have a set of larger OD and larger thickness o-rings on the way, but I'm not confident at this point. I have a source that has made "sleeves" that reduce the LS2 bore down to LS1 inector size, but I thought someone here might have an alternate solution.

Anybody else??

I have done the swap. I got the orings from sdpc and the part number is 89017587. I just stacked two nuts to space the rail up 1/2". It was the easiest part of the install.

Call me i have 2 sets of the orings in stock!!

Scoggin Dickey's don't work. There is absolutely no way those o-rings will seal properly, especially over time.

Looking into G-forces solution

I have sold well over 40 sets of these and have yet to have anyone run into a problem. Let me know what if you come up with a better o-ring & if I need to look into something else!!

It is dangerous using the ls-2 o ring on the older injectors they are to loose, a real potential for vacume leaks. I machined up some sleeves and pressed them in the ls-2 intake,a little bending and redrilling will allow you to use your old fuel rail also.

Dave F

do you have the sleeves available? I've gotten the rail taken care of, but still working the the o-ring/sleeve issue. Katech supposedly has orings with propper ID and OD, but I haven't gotten them yet.

I check, and my intake defintely leaks with the Red LS2 orings installed.

can I use the truck style injectors off a 07 GMC old delphi small injector plug, I beleave these are refered to as mult tech injectors. I need to instal them into a LS2 intake manifold, do I also need new intake manifold bolts? am I better off wiht a LS1 or LS6 intake can I then reuse my injectors?

mmmm which way is correct? You say fuel rail spacers, and another guy from fuel injection shop said I need injector top hat sapcers, my injectors are truck injectors not LS1 injectors wonder if they are too long or too short compared to the ls2?

I never got a good answer from anyone, even lingenfelter was not sure if it would work, fast wanted me to buy their 500$ kit, my injector company said i needed different ones.

My setup was with ls1 injectors and it ended up working just fine. Not sure the differences going to truck ones.
