dgoodhue Posted November 25, 2018 Share Posted November 25, 2018 On a 2.5i with the motor swap, I would do valve cover gaskets, head gaskets (Many start to leak around 100k), timing belt, pulley, tensioner and water pump. IMO stick with OEM for the timing belt components. Probably a good idea to change the plugs if they are due (every 30k miles) I think ARP heads stud are overkill for a 2.5i. Same goes for the Killer B pickup, upgrading the oil pump. Link to comment Share on other sites More sharing options...
TimothyOnline Posted November 28, 2018 Share Posted November 28, 2018 I think ARP heads stud are overkill for a 2.5i. Same goes for the Killer B pickup, upgrading the oil pump. I'm going for a "poor man's WRX" theme here. I see you're new here, but my car is well known by us older members. I keep a note book with everything done to the car. Impressive! It's amazing how much longer peoples' cars would stay on the road if they would only take a few minutes each week to punch things into a website (i.e., myCARFAX) or run their receipts on a scanner. I hope I didn't come off as as insidious; I have merely heard recommendations to stay away from non-OEM coolant for fear of head gasket problems. If newer head gaskets (i.e., MLS) are addressing the issue, then that's a win for all of us who get ramrodded into buying "All Makes / All Models" coolant at gas stations. :thumbsup: Link to comment Share on other sites More sharing options...
Max Capacity Posted November 28, 2018 Share Posted November 28, 2018 I do have ARP head studs in the wagon and great tunes in both cars. Also, over the years on here, I have not heard of many GT's with HG problems, compared to 2.5i's. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

It is your car & you can do what you want My response was directed towards the original poster daughter car with a 150K miles and likely a 4EAT. He probably just wants something reliable for her. I was just trying to steer him towards where I would spend my money on a daily. Link to comment Share on other sites More sharing options...
hadvw Posted November 28, 2018 Share Posted November 28, 2018 Just one note, and this may or may not be controversial: I had my regular (non-subaru) mechanic do a compression test, and he got around 75-80 psi for each cylinder. Which is way low, even for the lowered-compression EJ255. He said he did it twice. Car was running fine, I was just curious if there were any issues to be aware of, as I had been thinking of trying HPDEs. Everyone agreed there's no way the car could be running normally with 75 psi. Took it to a subaru shop, who told me he doesn't do compression tests anymore, they're not that useful on Subarus, and did a leakdown test instead, with 5/7/5/7 % loss (resonable numbers for age/mileage). YMMV. YCTMAV (Your Compression Test May Also Vary :-) Link to comment Share on other sites More sharing options...
Max Capacity Posted November 28, 2018 Share Posted November 28, 2018 Yep, the important thing about the compression test is that all numbers are within a %. doesn't really matter what the numbers are...within reason. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.
