Hello everyone,

I bought a precision turbo and don't have the downpipe or the elbow. I do want to get one made and I'd really want some suggestions into what I should be buying as wanting to keep the stock cat and running a cutoff switch such as this one:

If I want to run the stock exhaust, will it restrict my motor hence harming or shortening the life of the engine?
I'm open to other suggestions or routes but I'd really be curious as to any recommendations.
Also, how do I figure out the sizing for the fitting that is tapped into the oil pan from the oil return line on the turbo?
I'd most likely need a new fitting as the previous owner did not include a tapped oil pan.

Best suggestion ever: tap timing chain cover for your oil return. -8 or -10 an bing will be fine.

 

When running a stock exhuast, heat is the thing you need to worry about.

 

-10 AN return (to the timing chain cover)

 

Thanks guys, any idea which vendor to go to get the bing to weld onto the timing chain cover?

 

if you go into the fi for sale theres a guy (catsS2000) hes who i bought mine from he sells them just pm him very fast shipping and very helpful!

 

thanks i actually contacted him about it! anyone know the deal with the flange size for precision turbos?

 

I believe it is based off a garrett t3 for the return line. At least the gasket I used was for a garrett t3.

The flange/tube I just made myself. I don't like using a hose fitting so close to the turbo, as it always crowds an already tight space.





And the only technical drawing picture I could find from precision that at least had dimensions.
