Thread: Turbo Oil Line and return line ??

i always use a nissport oil dist block for the oil feed coming off the oil filter housing.

then i do a 1/8" npt to -4an

then i make my an hose to whatever length i want

if turbo is ball bearing with -4 run a restrictor

or -3 an hose

with the drain i would run a -10 an hose
i use a 3/8npt on block to -10an fitting

ATP offers all these things to setup just about any turbo or setup
they sell premade hose for feed and drain
or you can piece together

Autometer has some good feed hoses that they sell for gauges but u can use for turbo feed

Replace #1 in your parts list with three of these. They are a little cheaper.
Earl's 981603 Earl's AN to NPT Adapter Fittings

#2 is right: Earl's 991701 Earl's Female NPT T-Fittings

Replace #3 in your list with this one if it is cheaper and you want to order all from one place: Auto Meter 2269 Auto Meter Adapters, Extensions & Fittings

I hate to say it, but your McMaster Carr links don't take me anywhere. =(

As for the actual hoses, get this one foot line: Earl's 63010112 Earl's Speed-Flex Lines

And this 3-foot line with 90 degree end: Earl's 63011736 Earl's Speed-Flex Lines


Those links above get you everything except the adapter for your turbo (something male to -3AN male), and the adapter for the oil pressure sensor (1/8" NPT male to 1/8" BPT male).

If you can find a Stewart Warner pressure gauge adapter kit (part number 1073) it has both of the special BSPT adapters you need. The one for the block, and the one for the sensor. It is hard to come by though. It's listed in this catalog: https://www.pegasusautoracing.com/2012/047.pdf

And that's where I bought mine a long time ago... But it's not on their web site any more. Maybe a phone call?

I found a new source for the adapter for the pressure sensor! And at $20, it is $10 less than what I paid a long while ago... =/

1/8" Male NPT X 1/8" Female BSPP Adapter: AirForce Airguns | Crosman Air Rifles | Benjamin Air guns | Beeman | Pellet Guns

So order everything in post #22, and this fitting, and then all you need is the one for the turbo to -3AN. And I think you will find part #402833 on this page is what you need for the turbo... But MAKE SURE before you buy.


It looks like it will be a $95 order from Jegs, plus a $20 order from R&L Gun Supply, and an $8.50 order from ANplumbing.com.

Thank you so much man i will place that order today see if they can ship it out on monday .. i will post a pic later on today of my turbo just to make sure what size thread it is .. is a Garrett T3/T4 .57 Trim
