What thread is the feed on turbonetics?

Im using my old oil line, but obviously my banjo bolt doesn't go in. What is the inner thread size on a turbonetics turbo (through AGP) so I can make my own?

The thread pitch on the garret oil feed is 1/8 npt. If you are using a stock feed line, you wont be able to get a banjo bolt with that pitch. If it is a braided line, you can get a 1/8 npt- #4an 90* fitting that will work. All you have to do is unscrew the banjo fitting from the line and then just connet it to the new fitting

I think the problem is finding someone who sells those. Any clue?

WTF Both of my Garrett CHRA's have a 1/4" NPT oil inlet.... 1/8" is small - that's what most gauges are threaded for.....


XtReMeToYz - Post a picture of the end (turbo side) of your current oil feed line and I'll get you the part number of the fitting that you need.

You might want to recheck that. Last 5 garrett turbos Ive had have all been 1/8" npt, including my current pte.

Look at these specs(dimensions) from turbonetics. http://www.turboneticsinc.com/turbo_dimensions.htm

I was apparently missing an oil filter that turbonetics includes with the turbos, so thewy sent me that as well. Solid 30 dollars spent WTF

That's very weird.... I checked mine yesterday, and it is definitely 1/4" NPT. Here's the write-up I did with the fitting that screws into the CHRA. It is the 1/4" to 4AN fitting....

So, it looks like it could be either one.

For anybody still wondering, measure the oil inlet of your CHRA with a set of dial calipers. If you measure approximately .360 then it is the 1/8" NPT fitting. If it is closer to .460, then get the 1/4" NPT fitting.

Thats odd. I have never seen a garrett center with a 1/4 npt oil feed. I guess that is their way of screwing with us and them making more $.

Anyway, thanks for the heads up. I will keep this in mind next time someone asks.
