I need some info on this cause i had an oil issue with my 04 sti and now have F'ed up motor......owwww the pain i feel....... and does anyone have a good engine with no more then 45000 up for sale with stock turbo???

I'm just wondering if the turbo has a built in oil restricter like the external ones needed in the Garrett bb gt series turbos. If it does, it would make sense to leave the filter in since otherwise it will have a high chance in impeding flow especially out of a .035" hole size.

Just read the other thread "Turbo oil-feed / AVCS line replacement" stating the restrictor is built into the banjo bolt for the turbo oil supply line. So I personally would not remove that filter. I would replace it if damaged or if you could not remove debris embedded into the filter.

I'm going to do a short how to this weekend. As of right now, my plans are only to inspect, clean, and maintain the filter.

I removed my filter yesterday. I thought it would take just a minute to do and 2 hours later and a trip to the parts store, I got it done. I used a ratcheting gear wrench to remove the banjo and when I got it all the way out, the wrench was stuck on the bolt and the bolt would not come out because the uppipe was in the way. So, here I am, oil going everywhere, gear wrench stuck on the banjo, banjo stuck from the uppipe. I had to push the oil line down and in the process, the copper washer under the oil line fell down, lost forever in the Subie twilight zone. I did, however, get the banjo bolt out just before the oil line was about to snap. Had to jack the car up and feel around all over the place for the washer-never found it.
Called Napa and they have copper washers. Took off in the wife's car for Napa and found a replacement washer.
Oh yeah, BTW, the filter was spotlessly clean-not a speck of anything in it. So, actually the entire process was a waste of time and now I read where the filter needs to be left in for proper pressure drop.
Is this true? Do I need to take the banjo back out? Please say no.

so you took your filter out?

i haven't heard anything but it does make sense that the filter does have an effect on flow and pressure. Because there is a possibility, i would be worried about the increased oil pressure overcoming the the seals on the turbo.

on the other hand, if forced performance recommends removing it then how effective of a restrictor is it?

I was hoping we would get more input from the pros on this subject.

My car is a daily driver with 410ft/lb of torque depending on which dyno you tune it on and I accelerate pretty hard most of the time but back off around 6-6.5krpms. I very rarely take it to the 7.2k redline. I have tracked it once and burned a tank of gas in 84 miles.

I use it hard but take really good care of it. Amsoil Series 3000 oil and check the oil at every fillup.
