20g oil feed an fitting

[Usatuff]

Anyone know what pitch and thread the banjo fitting is on the turbo? I already have a bunch of SS line laying around so I just need the fittings and don't want to buy a kit

Either 12mm x 1.25 or 12mm x 1.5.

what would be recommended for SS line size, I have -4, -6, and -8

 

[JusMX141]

-4AN at the biggest.

A 20G is designed to be fed from a low-pressure source, so use caution if feeding the turbo unrestricted from the filter housing with a -4AN supply line.

All MHI turbo oiling information can be found here.

I was actually thinking about keeping it the way it is, off the head. Or would the OFH be a better place for the feed?

As long as you're not going insane and running as much boost as the turbo will make, the head feed will be just fine.

Curt Brown's 1G which set the no-nitrous Evo III 16G record was using a factory 1G feed line from the head.

Yea I don't plan on going crazy because it will still be drivin daily in the summer. Also do you know what the pitch and thread are of the bolt in the head?

I know this is an old thread but thought the info for this could help since there was no one size mentioned. There are 2 different CHRAs 20Gs can come in. If you have a 20G hybrid out of a 16G then it will be 12x1.25. If it is a true 20G then it iwll be a 12x1.5. I am having issues finding the 12x1.5 banjo bolt and decided to go with a/n fittings to lessen the headache I already have over this car.

Thank you, but that was covered in post #2.

It doesn't matter whether the 20G was bought or built, it can still have either thread on the inlet. I've had brand new 20G's from a Mitsu box which had either. The most common among 20G's is definitely 12mm x 1.25.
