Tonight Zoomzoom and I installed a pair of Dave Newbern’s Bosch injector sleeves .


As many of you know the diameter of the secondary injector openings in the LIM is larger than the outer diameter of the o-rings on the Bosch 1680cc injectors.



Dave’s sleeve provides more support for the o-rings by filling the gap.


Dave included a set of detailed instructions with the injector sleeves AND a throttle body O-ring, which he is/was apparently sending out with the bushings because he has a bunch of extras. What a cool guy! I highly recommend Dave’s product to everyone using 1680cc injectors.

Great idea, thanks again Dave.

Your a good mechanic!

With the injector sleeve, can you leave the diffuser? I know a bunch of people who had to remove it using other rails.

I reluctantly removed my diffusers a long time ago so I'm not sure. However, from what I remember the nozzles on the Bosch injectors are too big to fit in the diffusers. Assuming that this problem was overcome I believe the sleeves would still fit with the diffusers in place.

Seems like a simple and elegant solution to the problem. And hey they're actually reasonably priced too. $25 isn't bad at all. What are they made of? Aluminum?

Those will not work with the diffusers. The injector will sit to high and you wont be able to bolt the rail to the manifold. I dont see a problem using those sleeves but they are not really needed since the setup works fine as it is.
