ETK Engines

I'm trying to make a different turbo for the F4 version of the ETK 800 series, but I can't seem to find the engine slot to actually find out what the slots are called. Where do I find this file?

 

in common.zip in vehicles folder

 

You mean the slot in the jbeam? If you're looking at the thing I think of, it's at the bottom of the engine jbeam

 

Thanks, managed to find it.
