I have a 70mm I've been fitting up to a project car and I am wanting to just do a fitting on the oil feed inlet.

I called up On3 to ask what thread the fitting is on the inlet side and they told me to buy the flange that bolts to the turbo that has the 1/8" NPT fitting provision. Seems like waste of money to me when the turbo is already tapped. They could not tell me what it was tapped for.

I bought an 1/8" NPT to -3 fitting last night but the 1/8" NPT is too small and doesnt engage any threads

I believe these are the same cartridges as master power so if anyone has info on an MP oil inlet, please post up

Thanks

the MP 70 I had was 1/8" NPT, are sure that's what fitting you have ?

I've got. 76mm and I'm pretty sure I used all the fittings out of my precision turbo on it. Ur local parts store should have an adapter if u need to adapt it up a size. Do you not have the 2 bolt flange that goes on it?

It might be a 1/8" BSPT instead of NPT. Honestly, I haven't tried to put a fitting on mine yet, but I suspect this might be the problem.

Absolutely, I bought 2, 1 for the -10AN gauge fitting that has a -1/8 NPT port on it for the oil feed off of the filter housing

My local speed shop has a ton of Earls/Russel/Fragola/RedHorse fittings but they dont carry the flange that could bolt up to the turbo on the inlet side. From ATPturbo it looks like it'd cost me about 35 bucks to get one versus trying to just get the right fitting for under 10 at the local shop

Its peanuts compared to the amount I've spent on the setup so far, but it doesnt hurt to try and save some $$ in unecessary places

In the picture you posted - the 1/8" NPT is the female end - the tapered male end is the -3 AN. Are you looking for something like this?

I figured it out today. I got to sifting through my bolt bins and trying stuff that might fit...

Ended up getting this in there...



Wasnt sure what pitch it was so I went over to the hardware store and found a nut that would mate up to it. The correct size is an M12x1.50

It looks like Earls sells an M12x1.50 to -4AN fitting so I'll get one of those and reduce it down to a -3

For kicks, here is the project so far

The oil feed kit that RPS sells screwed right into my On3 Turbo. I'm almost positive its 1/8NPT/ -3AN. I have the 2 bolt adapter for the drain though.

just for kicks by the way, if you have your old valley pan flanged bolts, they thread right into the ON3 oil feed and drain flange mounting holes lol i found this out after i figured out that the bolts that came with the feed and drain flanges i geto were entirely too short lol
