My 73 Suby drivetrain conversion upgrade!, New rebuild going in January 2025 Options

Okay this has been a long time coming. I am finally going to pull my incredible, reliable, powerfully awesome 158 hp NA 2.5 Subaru Drivetrain. In goes my new 2.5 Subaru Turbo motor out of a 2009 Forester XT. I will be pushing 220 plus depending on if I upgrade my turbo over the stock one. Pretty sure I am sticking with stock to start. That is a pretty easy bolt on upgrade later. I have a 2004 WRX 5speed tranny to mate up to it. Will be doing a firewall engine mount connecting to a Small car motor mount. Tranny ears for the back. Using Outfront header to move the turbo around the front of the motor. Outfront Wiring harness to the Stinger ECU. Still need to figure out the intercooler but staying in the engine bay under a GT grill. More details to follow but plan to pull my old drivetrain this weekend.

Okay so plans have changed & I am going to be putting in this 2005 WRX motor with 55k on it. My 2.5 will go in eventually but my plans are to build it out a little more. Going to get a larger turbo for it & other odds & ends to push 400hp with it. So this 2.0 motor will be pushing 220 easy & looks great

Did a little more test fitting. With the tranny hangar's it sits a little low. It can go up another inch at the least & I think closer to 2. Compared to my previous cradle & tranny setup. Which definitely sat up higher. Where it sits now I wouldn't need the cutout for the starter & clutch fork. I would rather have it sitting up higher even if it means a small cutout in the truck. Of course I also have the cuts already so only makes sense to keep it that way. Things do line up nicely to use an early stock engine bar. With a little customized piece attaching to the front of the small car motor mounts.

Anyway thats all I have time for. Heading to Dallas for a week for work. Then a stop in Phoenix to golf & catch a spring training game or 2. Plus a bonus I get to meet Rich. He bought my original suby drivetrain. So we'll get to talk 914's & conversions for a bit next Friday morning. Couple pics of it up in place. I also put the intake back to stock. Was going to flip it but that won't work with me doing A/C. Won't be to big a deal on the intake. I'll just use a similar bend to what I had before. Instead of it going to an air filter it will got to my Intercooler. Just going to start with the stock air intercooler & see what kind of results I get. Most likely will end up with a different intercooler setup. For my initial install it will be fine.
