My fabricator is making me a downpipe and manifold for my EFR6258. Unfortunately he is a long way away and is working from a jig, as he has made this setup before. However it was with an earlier EFR6258 (investment cast hotside) and I have a newer (sand cast hotside). We are wondering if the exterior dimensions are the same and if his other setup will work for my turbo. They are both the Borg Warner EFR6258 just in case there's any confusion.

I'd like to see if I can avoid paying for shipping to get my turbo to him if he doesn't really need it.

 

Im not sure how to tell which is which however I have an efr6258 here I could measure.

I have a sand cast one that I can measure for you. Which dimensions do you need?

Edit: I now realize that would be useless, since you have a sand cast one too...

 

Sand cast doesnt have borg warner engraved on the hotside

 

Well I know soviets first turbo was investment cast. I believe his new one is sand cast. He didnt have to change anything.

And it would be ******* moronic if borg made the new efr not bolt in the position of the old efr that got replaced after turbine hit muffler.

 

Exact same housing dimensionally.
