Welp, making progress still
undercoated the bay

cleaned up the intake manifold while swapping to the pasture TB.

Also swapped cam and crank gears to the pasture car parts to match the ECU which is officially done now thanks to the local expert.

Had a really dumb moment where the motor wouldn't seat on the trans due to the friction disk not being lined up perfectly but thats what i get for putting the clutch on with the motor hanging in the bay.
Glad i figured it out and got it bolted up, onto the next thing.

I put the American engine harness back onto the motor and found i am 2 sensors shy of complete. :?
figured out that it was the Camshaft position sensor and the knock sensor.
The JDM motor did not have either but very luckily has a spot for both so i ordered those and put together what i could without making it hell to add a knock sensor later.

welp, still updating, not that anyone cares but trying to keep track of this build.
Last weekend was very productive, don't have any pics but i got my oil pick up shortened and the temporary "shortened" pan on until i can cut and weld the actual longterm pan. Cleaned the exhaust ports and mounted the factory subaru manifold which will need some work as it hangs crazy low and the flange almost touches the rear apron. Not sure if I'm going to attempt this myself or let a professional handle it but I'm tempted to take a crack at it.

After all that i was able to put oil in it and gas it up then try to fire it. EXCITING! until it didn't start. I was still reeling from the fact that i got everything connected to even crank so i didn't get too bummed out. No swap starts on the first try, right? I went back checked everything to make sure i wasn't missing something and couldn't figure it out so i had the wife try again and this time the fuel pump decided to start leaking so i called it immediately.
Ordered new fittings and I have a spare pump just in case but i feel like it might be overkill. My close friend who was helping me a lot when this project started, ordered this pump and its like 75psi operating where the factory was about 37.
I have an adjustable FPR with a gauge on it that i might throw on to be safe. Not sure how the factory FPR is handling the extra pressure. Could just buy a lower pressure pump i suppose but this pump is already on the car and i can just lower the pressure at the FPR.

Planning on really running the wires and mounting the ECU this weekend as i know that i have them connected correctly to crank now. Once that is done and the fittings come in I'll start troubleshooting the no start, make sure i have spark and all.

Thanks for sharing your build! I often find myself talking to myself here too lol

I like your plan for the radiator. That's where I would want it to be if I ever go this route. I have a Kombi which I plan to convert to Subaru power, so a lot of what you're doing won't help me, but a lot might

I'm looking forward to your next post!

Thanks Dean!

Haven't had much happen on it lately, The fittings for the fuel pump are taking an eternity to get here and i want to make sure it fires before i go much further. Still not sure exactly how i want the radiator but I'm now considering running it kind of angled to the decklid with the offsets on to make sure it gets plenty of air. lower mounting would be easy with the motor and plenty of empty bolt holes but I'm wondering about the upper mounting. May be necessary to use some rubber mounts if attaching to the body as the motor will obviously move more.

ALIVE!!! ITS ALIVE!!!
got the fuel pump back in and fired it up. Sounded like it was down a cylinder or two at first but they eventually fired up and sounded like it was running great. Need to get the radiator in and pumped so i can run it longer.
