im sure someone has done it but is there a turbo that will bolt on to a base model 850 and can it be done for a reasonable price?

 

nope, just buy a T5

 

Yes. Put a for sale sign in the window of the n/a, sell it, and buy a turbo.

 

It can be done and has been done. It's not easy and it's not that cheap unless you are a good "U pull it" warrior. Have you done any research on what you'll need to modify to do it or are you just asking if it can be done and have no idea what's involved ??

If you have no clue and haven't done any research on what all needs to be changed besides just bolting on a turbo its easier for all of us and you if you just sell it and buy a car that's already equipped.

But, yes all the Volvo turbos will bolt on once you replace the exhaust manifold that's the easy part, the plumbing and support systems are what gets involved. After all, a turboed 2.3 is almost identical to your base 850's. There are different cams and little things.

 

planning on doing this in a few years when I buy a newer car
you're looking at new exhaust (manifold and downpipe), intake tubing, intercooler setup, oil lines, you'll either need a new computer or megasquirt it
I'm sure there's more, but that's what I can think of off the top of my head
and don't let anyone tell you the engine can't take it
the only real difference in the internals is that the turbos have a less aggressive cam and their connecting rods are 5mm shorter (not stroked, lower compression)
so... if you're willing to put the time and money into it, assuming you're starting with an engine in good shape, you'll be making much more power than a stock turbo

 

Different ecu, exhaust, intake, intercooler, wiring harness, TCV valve, exhaust valves, vacuum lines, and injectors are what come to mind immediately. Additionally, you'll need to change your head gasket to a thicker one to accomodate the lower compression ratio (10.5 on the n/a vs 8.5 on the turbo) that the turbo is goona need.
