Cutting Zf5 ear for ATS turbo up pipe clearance?
- Thread starter mjpike

I don't remember it being so much a clearance issue with the up pipe as it was with the down pipe. Some one already cut and ground the ribs on the back side of my ZF before I got it but as you can see its a tight fit. Gonna have to go look to see how the cast up pipe clearance is unless some else remembers off hand.
Here is the up pipe clearance, doesn't really look like any thing was cut off to make it fit

I never had to with my factory and 093 ATS kits. I think you may have to with an 088.

Mine has a 085; used the install instruction for the 088, and they appear t be the same except for the airbox.
States in the instructions that you have to trim that triangular chunk off of the trans for downpipe clearance. The one your down pipe is hitting in your first pic.
At first, I left about 1/2" of it left on the transmission, and the downpipe rubbed on it and squeaked, so I knocked another 1/4" or so off of it, and everything clears now.
A sawzall makes really quick work of it from under the truck. I was able to trim it the 2nd time without even removing the downpipe.

I've been made aware offline that the ear seen is whats supposed trimmed earlier in the day. It still went in and did not touch the trans when the support was snugged up but it is super close.. First pic is the initial eng/turbo swap, second is today. Now I know where my exhaust leak is coming from.
You'll probably want to replace it to help deal with any vibrations/movement that occurs. Don't want the slip joint wearing causing leaks prematurely. If you have access to a torch or a big enough wrench you could probably just fab another one if you can't source another or weld your old one back together.
