How to change my 1976 L28E to an L28ET

[76_280Z]

Hey everyone,
I’m working on converting my 1976 L28E into an L28ET and could use some guidance from those who’ve done it before. The engine is already torn down, and my goal is to build it back up as a turbo motor from the ground up. I’m planning to run around 8psi of boost—nothing crazy, just a solid street setup.
I’ve searched through the forums and found bits and pieces, but I’m hoping someone can help me with a more complete list of what I’ll need. Specifically:

• What internal components should I upgrade or swap (e.g., pistons, head gasket, oil pump)?
• Which turbo setup works best for this kind of build?
• What ECU or fuel management options are reliable and relatively straightforward?
• Any tips on sourcing parts—junkyard compatibility, aftermarket suppliers, or trusted vendors?

I’m not looking to cut corners, but I also want to be smart and cost efficient about sourcing parts. If you’ve done this swap or have solid info, I’d really appreciate your input.
Thanks in advance!

Did you see the turbo threads here?  Kind of hard to find.

You don't need to change anything internally. Typically you would add some top ring gap on a turbo motor, but these motors already have plenty.

My build is probably the cheapest high tech option possible, and I am very happy with the turbo's response and power. Back in the day it would be simply swapping some junkyard turbo model parts, but these days they are rare and not worth it. There are many ways to go about it, main factor is budget.
