AVGxp Posted August 24, 2020 Share Posted August 24, 2020 (edited) I recently got a VF52 to replace the stocker in the car which appears to be going. Along with it I got a inlet hose, and a ebay intercooler (temporary solution, I didn't need better performance just something that doesn't leak). I've gotten a kit with all the turbo gaskets I'll need but I was wondering if there are other things I should do while replacing it. I'm planning on replacing the pitch mount as well with a group n variant, is there anything else that will be easier to do or I should do anyway while I have the turbo out?

Max Capacity Posted August 24, 2020 Share Posted August 24, 2020 New oil return hose. You'll have the inlet tube off so it might be easy to line that up after the turbo is on. The vf52 also requires a Tune which will need a Cobb AP. I find bolting the turbo to the up pipe makes it much easier to line things up at the same time. oil return, inlet and up pipe. I found the studs get in the way. Oh, use anti-seize compound on all threads. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

blue wrench Posted August 24, 2020 Share Posted August 24, 2020 This would be a good time to unscrew the banjo bolt that feeds oil to the turbo and inspect the filter inside. Clean it, replace it, or remove it. Is this on the 08 Legacy? If so then you may also need to replace the top section of the oil feed line that bolts to the turbo and the lower coolant hose, due to different lenth/fitment from the stock VF46.

Thanks for the heads up, didn't realize they were different. I'll add that to the list Edited August 25, 2020 by AVGxp Link to comment Share on other sites More sharing options...
chato Posted August 25, 2020 Share Posted August 25, 2020 upgraded oil feed line might be a good idea Link to comment Share on other sites More sharing options...
AVGxp Posted August 25, 2020 Author Share Posted August 25, 2020 On another note, what's up with the stock bpv? Can I reuse it and does it need anything replaced when I move it over? Link to comment Share on other sites More sharing options...
Max Capacity Posted August 25, 2020 Share Posted August 25, 2020 (edited) It will be fine. Both my cars set have stock one's. The third picture shows the T fitting in the line to the Fuel pressure reg instead of that hose coming off #4 intake runner.

Rojasher25 Posted August 26, 2020 Share Posted August 26, 2020 upgraded oil feed line might be a good idea+1 Iag braided hose kit. Fairly inexpensive and makes connections easily accessible if you ever need to disconnect in the future. It feeds the vvt solenoid and the turbo. We have replaced a couple oem ones that crack.

AVGxp Posted September 12, 2020 Author Share Posted September 12, 2020 So I finally looked at the turbo the day before the swap and I don't have the coolant lines, I bought new oil lines anyway but I haven't been able to find the coolant lines by themselves for sale, does the dealer sell them separately?

Max Capacity Posted September 12, 2020 Share Posted September 12, 2020 Yes, the dealership or any of the on-line Dealers parts site will sell them. This list here works pretty well. https://legacygt.com/forums/showthread.php/oem-online-subaru-parts-vendors-list-42243.html Most local dealers now have the same on-line pricing. Check your local dealers site for "parts" 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

dgoodhue Posted September 13, 2020 Share Posted September 13, 2020 How do you know the stock turbo is going? Is it is the turbo bearing, have you checked the oil for bearing material? There is no point in putting a new turbo on an engine that has metal in the oil. Link to comment Share on other sites More sharing options...

There is no point in putting a new turbo on an engine that has metal in the oil. I took the car to a subaru specialist autoshop and they told me the turbo is in bad condition. So today I took it apart and there is scaring in the turbine and some shaft play, but that's not even the fun part. The previous owner had swapped in a td04L-13t, I don't know if it's just because he had a bigger turbo he didn't want to sell the car with it or he wanted the faster spool of the td04. https://imgur.com/a/NGharpZ Edited September 14, 2020 by AVGxp Link to comment Share on other sites More sharing options...
Rhitter Posted September 14, 2020 Share Posted September 14, 2020 It's probably because he exploded the OEM turbo and wanted to make it "run" before dumping it. Get an oil analysis done. Look for metal in the oil. My OBXT build Link to comment Share on other sites More sharing options...

Look for metal in the oil. I just had an oil change done and the car has been sitting for weeks now while I waited for the title to come in. Do you think I'd have to run it a bit more for an oil analysis? Link to comment Share on other sites More sharing options...
dgoodhue Posted September 14, 2020 Share Posted September 14, 2020 I would return the car if you can (even if you have to eat some of the costs). There is a very high chance of your car needing a motor once you start driving it. Link to comment Share on other sites More sharing options...
Max Capacity Posted September 14, 2020 Share Posted September 14, 2020 I would think 100 miles on the oil would be good for the sample.

I'm actually not too concerned about it, except for the turbo the car is in really good condition so I would think it was maintained well before being passed to the sucker that I am.

Max Capacity Posted September 15, 2020 Share Posted September 15, 2020 Main thing is you want the sample when the oil is warm. Not just after a start up. BTW, I use Fumoto oil drain valves on my cars. Look them up. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
