How much do complete turbo drivetrains go for?

[racing1g]

I recently purchased another GN with body issues but a flawless drivetrain and i'm wondering what they are currently going for. 1987 GN with 90k miles, all stock except for a turbonetics upgrade turbo, precision extended stock location cooler, and mildy built 200r4. I can't seem to find any for sale to get a reference price, mods i'm sorry if this is in the wrong spot.

Edit: It after looking again it's pretty much exactly like my other Buick. It has 42.5# injectors, Terry Houston 3" DP, and a MAF translator as well.

That is pretty clean, I can give my opinion on a Low /high estimate I figure: $2500-4000 for turn key engine. Trans add $400-800 unless you have a build receipt for the trans you usually don't get too much more.
That is if it is running well with no strange noises.

Thanks for your advice, it all runs like a top but I have no use for another drivetrain. Looks like she may be going up for sale!
