Where To Find .075-.080 Oil Restrictor for MHI

[spadepro22]

I'm looking to find a kit or something with a .075-.080 restrictor to feed a MHI 20g. I've seen hoses and stuff but no restrictor.

How about an FP oil filter and restrictor? I'd drill one to size.

Forced Performance Turbochargers: FP -4 AN Inline Filter

I asked FP over the phone and I told them I wanted the black filter and was going to drill it to .075" but they recommended the red filter. I explained everything about my turbo and they still recommended me the red one which is .125" orifice. I have a 14b center section converted to a 20g. Haven't ran the turbo yet so no first-hand experience.

Just buy the -4an aluminum fitting off ebay for ball bearing turbos and drill it out to the diameter you want. I did the same thing and haven't had an issue yet. Came with a .040 and drilled it out to .075.

Here is the one I'm talking about, they have -3an and -4an:

Another reason I decided on the FP filter method was because it acts as both a restrictor and a filter, plus I can monitor oil pressure after the restrictor.

I ran the fp red filter with my borg and still spiked over 100 psi to the turbo. I then switched to the ebay fitting I have now and have yet to spike over 100 psi.

Where is the -4an? And then I just take a .075 dill bit to it?

Make sure you put a gauge at the turbo and check it. Defiantly err to the high side....It's easy to fix a smoky turbo but one with a junk thrust bearing is garbagio!

The 4an is on there somewhere, if its not just give it a day or two and it should pop back up. And yes I just went to the hardware store and bought a drill bit thatvwas equal to .075.

pm me i have one, if you want.

I have also drilled the black fp filter, worked like a charm. I actually prefer it since it has a built in filter.

For checking pressure I used an inline gauge adapter, it has a 1/8 npt threaded hole so you can hook up a pressure gauge:

I called extremepsi and they said the line was -4an so I guessing -4an fitting would work. Could some verify that?
