Good evening to all from the East Coast. My name is Derek, I've had a 5th Gen Legacy GT for about 2 years now. When I purchased this, it was at 19X,XXX miles with 1 owner and 11 pages of service history from a dealer. This has been a GREAT CAR! Super fun and love the challenges associated with having a unicorn. Recently I wanted to rebuild the suspension in the front from the ground up and replace absolutely everything. I also needed to do a timing belt which is what led me into this position I'm currently in. Look below at the waterpump I had to cut out with tin snips
DISCLAIMER: I know this will be A LOT of work. I currently work as a mechanical engineer and design custom equipment for different industries and have automotive design experience. Also I know some of this may have been talked about before, information is kind of scattered everywhere so I apologize for that. If anything please just enjoy my struggle.
ALSO: This car is actually really clean with no rust on the body and has limited rust everywhere I'm not removing parts lol.
Since I've gutted a lot of stuff from my car to drop my turbo and remove the water pump, I discovered I need a rebuild on my turbo. I'm very temped to figure out a new setup with the turbo in a more "normal" location. I currently have a FMIC from my 04 WRX I was going to retrofit into the front of my car and create piping to route everything. I wouldn't mind running a down pipe from a typical WRX but I don't know that it would clear underneath the car (it looks like it would be TIGHT).
Another concern of mine, and a large one at that, is the heads. I currently have STI heads from a 2011 as I know that the heads on our cars are special. Is there anything special that may be needed to just bolt the STI heads on my block? I know that it has a special blueprint according to IAG.
As for the headers, what exactly would need to be changed? I have access to my own license of CAD software and can model pretty well.
This very well could be worth not doing, that's why I figured I'd ask. It may just be worth slapping a rebuild kit in my turbo and putting everything back on and leaving it the way it is. I look forward to responses as I haven't heard or many if any people attempting this.
