I just got my turbo kit in from Autoworks and it came with 440cc precision injectors. They didn't come with the bushing for the IM, just the o-rings on the injectors. When I went to install them they wouldn't sit in the stock bushing all of the way. Do I just lube them up and put the fuel rail back on and tighten it down? Or do I need to shave some off of the inside of the bushing?

 

for my rc's i shaved some off... I would assume that you have to do the same for the precisions.


Looking at the pictures, it definitely looks like you need to trim some down...
Try a dremel.

 

Dremel the o-rings so the injector fits snug inside of it.

I just put the Fuel rail on and tightened it down. Fit perfect IMO I think that is the way to go.

x3. Avoid forcing things. Can you tighten the rail until it squishes the incorrectly-sized o-rings in? Probably. Should you? Probably not. Premature breaking and/or shifting in front of the nozzles can occur, and nobody wants that to happen at 14psi

 

my 780's fit fine, i just used a VERY small amount of vaseline put it on with a brush, and they fit nicely.

They didn't exactly snap into place, but they went in with little effort. I was just expecting them to go in like the stockers. So I got them in and went to connect the plugs and they wouldn't go in. After searching for the reason I narrowed it down to the little nipple, inside the center section, by the metal prongs. You can see what I'm talking about in the pic of the 2 injectors in the manifold in my first post.

Here are some more pics of them installed and with the injector next to the plug.

 

Problem solved! *edit* You can tell on the one in the top right corner better!

 

I was told with my RCs not to shave anything off the o-rings the instructions also said not to

I'm not going to touch the Bushings. I think that they were designed that way.
