Good evening all,
I have a 1993 with a Garrett T04Z. I am looking to replace the turbo oil feed and return lines. I found a bunch of things on the feed side that reference 4-AN lines and fittings so I think I'll go that route. But I'm not clear on the adaptor that I need to go from standard NPT to 4-AN on the top of the engine near the oil fill tube. Can anyone here provide guidance on that? And for the return line, is the factory ovular connector with the 2 bolts at the top and bottom a "standard" size? Like, could I buy a flange for a T4 turbo and it would bolt up there to the side of the engine? Or do I need something specific? Or (best case senario), can anyone link me to a feed/return kit that has everything I need? Thanks!

 

If these are the questions you're asking you'd be better off handing the car to a shop. It doesn't seem like this is something you should be messing with.

 

This might be a better question for the single turbo forum.

Do you have the turbo currently running in the car and are looking to replace old/ratty/leaky lines?

I think it's fairly well documented what size lines and what type of adapters you would need. I'd dig through the single turbo forum.

If you are putting that turbo on now, that is a SUPER old tech turbo, going to be lag city.

For the oil feed, you want this adaptor: https://www.summitracing.com/parts/EAR-9919BFHERL

For the return line, I used this for the front cover; https://www.ebay.com/itm/32488631430...hoCNckQAvD_BwE

 

Awesome thanks!

Lol, all due respect, I'm ASE master certified and used to work at KDR when I was a kid. Just couldn't remember and wanted to ask before disassembling so I had all the correct pieces I needed :-)

I have a tool or two 😉

 

Appreciate the input Dale. Turbo was on until last night. I finally had it with the exhaust leak and disassembled to determine cause (warped fanges, go figure). So i figured while i had it apart I would redo the oil feed and return since it's a little economy-engineered at the moment. Functional, but certainly not ideal. Thanks for all the input!
