Can a C Type Turbo be Switched out with a D??

[Commander5993]

I've been reading up some about the Turbos, and I just need to confirm a few things.

First, our deuce has a C-Type "whistler" turbo.
Question: Can I replace this C-Type with a D-Type Turbo?

I know I've read some threads, where members seem to state that they changed from one type to the other.

But can the Turbo's be exchanged and bolt up without any modifications?
Or does something else have to be changed or modified when doing this?

Also is there any further engine modifications or adjustments that would then have to be made??

Thanks in Advance for Any Replies!

Straight across switch. No mods needed.

"C" and "D" turbos are completely interchangeable as stated. There is a gasket on the oil tube, you might want to have a spare on hand in case you damage it taking the old turbo out. Other than that its a no-brainer swap.

If your looking for a d turbo i have one off the truck already that ill swap for your c turbo.

I have no dyno proof, but I know my C to D swap yielded lower EGT's (50-75F) and 3-4 more psi of boost. Oh and it make it livable while driving.
