Here's what I experienced with the install:
Xcessive LIM with KGParts Rail and 1680 injectors:
1. LIM sits more towards the front of the car. This wasn't a huge deal, but it made the Greddy Elbow sit closer to the Cusco Strut Tower Bar. And since I have Poly motor mounts and the LIM causes the engine to be raised about 10 cm, I had to grind the Elbow a bit to fit and mash the Cusco bar on the underside. PITA!
The other problem was that since the LIM and now UIM are more forward, I couldn't use my stock oil inlet pipe, so I had to customize a 2nd Gen pipe a bit.
2. The KGParts Rail does not fit as is with the LIM. I had to do two things.
First I had to add about a 1/8 inch shim under the bracket to raise the rail so it would fit correctly with the injectors. The injectors looked like they were in the right place as far as the holes go (centered).
Second, I had to radius the injector rail brackets at the bottom (I think on the outer side) that hold it to the LIM otherwise they hit the LIM.
3. The plugs for the additional injectors suck. They are hard to install and I don't know if they are fully seated and not allow any vacuum leak. They don't move but...
Hope that helps.

Brain fart: And since I have Poly motor mounts and the LIM causes the engine to be raised about 10 cm...
The LIM does cause the UIM to sit a bit higher (but not 10 cm); what I wanted to say above was that I also used their oil pan and that caused the engine to be raised about 10 cm. Duh.

Yeah it does make the UIM sit farther forward, causing the oil filler neck not to fit. Also, I'm guessing your installing this on a single setup, is this correct?
I'm using the plugs they gave me, and they don't seem to be leaking. (No funky idle issues etc.)
If you use a stock fuel rail, (not the KG one.) you will have to grind bolth the LIM, and the rail to make everything fit.
