Hello I have a Porsche 914 with a built up 4 cylinder, with a remote full flow filter, the bypass in the engine case blocked. I have been using a Motorcraft FL-1HP filter, it has a 600 psi burst strength, which my engine builder says I should have because of the full flow conversion. Well now I find that I cannot get that filter anymore, out of production..
So what filter is a good replacement?
I see WIX has two filters that cross reference to the motorcraft filter. wix 51515R, and wix 51622 I called wix and they told me that they do not have a burst pressure for the 51515R, but tell me that of the 51622 is 500 psi. That 500 psi maybe close enough, plus the 51622 filters to 28 um they told me, were as the 51515R filters only to 61 um.
So I was ready to order the wix 51622 from Summit Racing, but Summit calls the 51622 a "transmission filter".
So what gives? is this transmission filter ok to use for engine oil?
Is 28 um of filtration considered ok? Or is there a better filtration level that comes in a high burst pressure can that will be safe for my full flow system?
I also looked at the motorcraft fl-1A, which is what ford told me was the replacement for the discontinued FL-1HP, but it only has a 200 psi burst pressure, which I dont thunk I want.
Is the wix 51622 with 500 psi burst, and 28 um filter size the best I can do? Are there other compatible high pressure filters with a lower micron rating?
What do you use in this kind of application? (I know the fram hp1 has a high burst pressure, but I have had them fail internally, and refuse to run any fram after having three different fram filters fail on me in the past)
Getting this kind of info from the makers is very difficult. The motorcraft phone help was bad, she kept asking for my VIN number after I told her it was a custom motor install, then she wanted me to spell Porsche. she didnt get it, ugh!
