Help! Difference between S4, S5 LIM, installing injectors
 
Ok I bought a turbo LIM and a UIM off ebay for my S5 TII. I asked him what kind they were S4 or S5 and told me it didn't matter. But I bought my injectors and they wont fit in the secondarys. I'm guessing it's a S4 manifold

My stock S5 TII manifold

The one off ebay

Yea I know right? I'm still kinda new to rotarys and ive never seen a S4 turbo maifold up close but it looks like someone cut some pipe and hammered them down in the injector holes. wtf?

They adapted it to run some aftermarket injectors. You will need to cut those pieces of pipe out to run stock injectors.

thats a s4 manifold with inserts to suit a differnt injector base to OEM injectors
if the inserts pull out , should be OK
- remember fit your atomiser cups and square edged base rubbers with your OEM injectors

if no atom cups, you can use double up squared edged base rubbers

Thanks everyone ill try to pull them out. What could I do if they don't, could I just cut them down and put a couple of washers for spacers below the secondary fuel rail if its too tall?

Ok I just got them out, those bastards were made out of aluminum. My first attempt with one went well. Sprayed silicon all over it, got a wrench and turned it then pulled as hard I could and it came out. But the second, different story. I guess with heat rising up and down it expanded the metal over time and seized in there. Thanks for the input

Just a thought, what kind of injectors would have this been for?

those may be the injector spacers for Bosch 1600's.
