I don't think I would with that many miles but who knows maybe they're all babied highway miles. If you do decide to turbo, get a compression and leak down test done to make sure your motor is healthy first.
First off the engine should be in a 100% healthy state before considering turbo. Like chillboy was saying compression test the engine and leak down aswell.
You can get the compression specs. from your service manaul (chiltons or hayness or factory). The compresion difference between the cylinders should be no more then 10-15%. If the compression reads below spec i would consider a wet compression test. Put about 15 ml of oil in the low reading cylinder and retest. What the oil will do is if the rings are bad it will seal them temporaily for the compression reading. If the compression increased then you know your rings are worn. If the readings did not change then you have a issue with the valves (ie. burn valve) or leaking head gasket.
A leak down test is similar to compression testing. The cylinder you are testing is at TDC and a pressure gauge is used to find out percentage of air leaking out of the cylinder. You will hear where the air is leaking and can determine what your problem is. (ie. bad intake valve or exhuast valves burned, it may blow into the next cylinder showing blown/leaking head gasket)
If you need any help doing any of these paticular tests, just ask.
You should generally know if your engine is in a healthy enought state to be turbo charged. Regardless of the kms/miles does not mean the engine is not healthy. does the engine burn oil? Does the engine blow smoke? Is general maintence done or is there a lack there of. Maybe the engine needs a quick refresher and it would be good.
i recommend you do the leak down and compressiontest and post back.
If you don;t know how to do a standard compression test you can ask here.

^^ good info!
i should do that on my beater.
but i have a question. with the wet test how would the compression raise if the rings are toast. wouldn't the oil just leak past it?

What the oil does is create a temporary seal. Mind you the weight of the oil needs to be high (40w possibly). The oil will leak past obviously if the rings are bad, however not all of it. It may not seal them 100%, but enough for you to see the compression raise.
