Turbo Oil / Water Feed Lines and Sizes

[Fender13Bender]

Quick questions, getting ready to finish up my engine and I'm going to go ahead and do the water and oil lines for my GT4094r before it's in the car. Top mount manifold, etc.




I'm going to do Summit AN fittings and stainless steel hoses, like so obviously:

What size do I need for the oil feed and return? -6 feed and return? And where do I find a restrictor to use with these lines? I'm really clueless here. Same thing goes for the water lines.

Thanks guys!

When i had a gt4094r it had the restrictor built in check in the oil inlet you should see it in there

-4 feed oil, 0.035 restrictor from ATP turbo, -10 oil drain, -6 for water lines.

It's been a while since I've gotten a restrictor so hopefully someone else can confirm or suggest another size.

Thanks man, perfect info.

Summit the best place for this stuff?

Any problem with running - 4 for oil feed AND water lines, or - 6 for oil feed AND water lines?

Sounds dumb, but I'd like them to match.

Does sound kinda dumb. LOL. If I had to choose I would go -6. You still have to run a -10. Your however going to have a hard time finding an adapter for your turbo oil inlet. Probably going to have to run a reducer at the turbo.

I personally like Fragola parts.

ATP stuff on the way


T4 divided gasket

-6 AN water fittings

Oil feed flange with built in -4 AN fitting with gasket

Oil drain flange with built in -10 AN fitting with gasket

Looks like on my turbo there is a restrictor built in, so I should be good there.

Alright, for those running water cooled turbos, where are you doing your water feed and drain?

I'm thinking engine block drain plug for the turbo drain, and using the location where one of the throttle body coolant hoses goes? Its next to 2 sensors under the imtake manifold, it's a threaded piece so I'd add an AN fitting.


I don't want to have no flow through the turbo or have it hooked up wrong. Will this work?
