360 LA turbo exhaust question

The easiest and cheapest solution would be to try and make a rear mounted turbo setup work. This will lower your temps and still produce 4 psi.

If your headers are still in good shape and are of quality, wrap them up!

If you want oem manifolds, that’s fine too, you can wrap those up. Going with rear exits would be better for a rear mount. Don’t bother cutting them out, the turbo is going to do all the induction work instead of a scavenging style exhaust design. What works here is exhaust gas velocity and smaller pipe size is ok.

Tie in both exhaust banks like normally, and choose to mount the turbo maybe on the other side of the T-case drop, so it’s still somewhat protected.
