A few months ago on a road trip in my 2007 Legacy I heard a ticking noise from the engine.
I pulled over to figure out what was going on, the ticking noise seemed to change with revs but not directly.
I decided it was best to drive the 30 minutes back home - gently.
Before getting back the ticking noise had stopped and I noticed the boost gauge firmly stuck in the bottom half.
We took another vehicle on the road trip and after a month or so of procratination, I finally pulled the turbo out of the wagon.
What I discovered was a twin scroll VF45 apparently with the twin shaft option, with the turbine and compressor flopping around like a d**k in a shirt sleeve.
I do not like this configuration.
I'm not sure how to proceed with a replacement. I've been looking for a second hand VF45, but haven't had a great deal of luck.
The VF44 seems to be more available. My understanding is that the VF44 was largely fitted to autos and has slightly different spooling characteristics.
I have a six speed manual (TY856WBEAA) with a EJ20YHFELE (atleast that's what the plate says).
A few wreckers have VF44 turbos for around $800.
Another option would be either of the TD04HLA-19T or TD04HLA-20T Kinugawa turbos which seem to be around for about $1800.
I would imagine that any of these options would require a retune. I'm not sure whether that would need to be up on a dyno or not.
Would a replacement VF45 require a retune?
Is there someone near Palmy who can retune legacies?
I'm also slightly concerned that there might be an issue with the oil supply, I wouldn't want to put in $2k of turbo to blow it up immediately.
Any tips on checking oil pressure with a push button start model?
Any tips on the replacement in general?
I'm not looking for a power boost, I enjoyed having it as my daily driver with enough guts to make open road driving a little more fun.
Thanks.
