Well I've been here for a little while. Have not offered much in entertainment so here is my stab at a build worthy of dorkumenting.
Little back history. Bought the OBXT new in 06.
Was a replacement for my single cab 2500 ram. Should have never dropped that truck from the fleet but that's another story. I was on the fence for a long time what Subaru was a good fit for my family. In the end the OBXT Limited fit the bill.
For years I just ran it stock. No mods just maintenance. Then came 90K and a weird issue. In the end it was a seized waste gate. My thinking the dealership would find the culprit while doing the 105K service and I'd be rolling down the road... Nope. Service was done but problem not solved. Only suggestion was a new Boost solenoid. Ended up at Garage One for further diagnosis and a fix by replacing the hot side of my VF40. a little over 600 bucks and it was good to go for quite a while.
FF to 120K and I started noticing oil seeping from the IC and really start getting my head wrapped around what is going on with this motor. Was having issues with stalling for quite a while. Picked up a Cobb AP and began throwing off the shelf maps at it.
Long story short here I have collected some nice hop up parts that aren't even on the car any more. Have gone back to stock on IC, intake, Up Pipe and what I really should have done was replace the AVCS. Wrapping all the vac lines was also a huge step forward. Lesson learned here.
So around 140K my turbo began squealing until it really warmed up. So it was time for a replacement. I decided to go with the 16G in the VF40 housing. Plus pull the perrin up and went to gutted stock. Main reasoning was visual inspection can be hit and miss fail with smog stations. I chose to look as stock as possible.
160K now and I'm for sure in head gasket failure land. Crappy looking coolant bubbles after warm up in the overflow. It's time to pull it.
Funny cause I have never heard of someone pulling the motor for a valve adjustment... Now I know why. It needs gaskets replace more that valve adjustment.
So I'm compiling a good size cart at Infamous now. Will add some items I'll get from Subaru. Hoping some of you experts can pipe in on some advice.
1) Should I just plan on replacing pistons and rings?
2) Better to just short block and rebuild this old one for future swaps?
Have discussed this a little else ware on the forum and really grateful local members are offering to help! This is huge!
I have not rebuilt a car motor before and going forward with it is going to be a learning and satisfying experience!
