Spent a few minutes and whacked on a 90* adapter with the TIG. I'll snag some VHT 2000* to coat the turbine housings to minimize surface rust (it does a shockingly good job in my experience) and these should bolt in place. I'll see once they're in if I have enough play in the exhaust to line it up, it should be REALLY close to the VS Racing units I have in place now and the flanges are all the same.

My water fittings should bolt right up, and I'll toss some AN fitting caps on the feed/return fittings on the motor and it should be ready to rock.
I do have a few other items left on the list. I put both CAN buses on one... bus, and it was noisy, which made the keypad mad. So I need to divorce the secondary bus. That's just making a quick adapter and moving a couple plugs over to it, so not a big deal. Once that's done and I can actually signal and honk the horn, I'm going to start putting miles on it and sorting out the tune.
The tune still confuses me a bit as I imported my Elite 2500 tune into the R5, but it's FAT everywhere. Dunno. But it runs great where I've leaned it out, so I'm sure there's a table somewhere that is different between the two. I've honestly not spent a ton of time working on that yet, so I'm somewhat excited to get it dialed in and start turning the boost up a little.
These are actually SMALLER turbos than I've been running (57mm vs. 62mm) with a similar size exhaust housing. As I have zero plans to forge this engine, the ~625-650 RWHP range remains my target, and I'll trade some peak HP capacity for nasty fast spool. Considering the displacement I think this setup should be a lot of fun.
Anyway, I'll throw these on this weekend, find out all the things I didn't think of, cuss a bunch, and then get annoyed and work on the Aston Martin the rest of the weekend. Probably.
