I recently bought a Garrett T3/TO4e 57trim turbo, the oil feed inlet on it is 1/4" compared to my old turbos 1/8" inlet. I cant find a 1/4" to -3AN fitting anywhere and that is the size oil line i was running on my last turbo..
should i just go up to a -4AN line? because ive found -4AN to 1/4" fittings.
or should i try and find an adaptor of some sort?

thanks in advance for any input.

 

Is there a chart to go by when choosing oil feed line size to turbo size?

This may help the op..

 

I use -3an and had a turbo with a 1/4NPT inlet before.

I used one of these to solve the problem: http://www.veneersupplies.com/produc...-14-to-18.html

 

Another option is running a oil feed flange. You can find them with a 1/8 in. NPT inlet and combine it with a 1/8 in. to #3 AN adapter. You can also find them with a built in #3 AN flare.

 

Thanks guys, yeah im gonna look into the brass adapter fitting for now.
Just so i can get my car on the road, ill probly end up upgrading to a feed flange eventually but the adapter should get the job done!
