850 R Turbo Problems?

850 R Turbo Problems?
Hello,
I am new to this forum and I just bought a '96 850R Black Wagon with 175K miles for a very fair price. It has a lot of little dents, runs a little rough and has stupid purplish tints. I plan on "restoring" it.
Before I put any time or money into it, I wanted to know if this was normal. When I drive it flat out, floor it, the turbo will "cut out" after a few seconds, but if I keep the boost needle right at the end it takes off like a rocket if the tires don't smoke. Is that normal? I don't know much about turbos, except they can be stupidly fast.
Also, when I accelerate from a stand still, it's kind of rough, unnecessary vibrations. Could this be fixed by a good tuneup and flushing the transmission?
Very interested in what you guys have to say.
thanks,
Dave

Where exactly do I look? do I have to take that "cover" off the turbo, it's hard to get a good look at the turbo. Maybe from underneath?
and, what kind of spark plugs, spark plug wires are best for an 850 R, by best I mean good performance and reasonable cost.
If these are too standard of questions is there an archive or list of common questions. I don't want to beat a dead horse, just looking for advice.

For the hoses on the side of the air box is the turbo boost control valve. Follow those hoses to the turbo.
For the Ignition stuff go OEM. Bougicord for the wires,Bosch for the cap and rotor. OEM plugs unless you are going to run High boost. If running higher boost Autolite Coppers work awesome gapped at like 0.26 to 0.28

Just check all the vacuum lines running between the turbo, engine, boost solenoid, etc. They tend to get cracked and old. For plugs, go with factory, and for wires, Volvo or Bougicord (they make the OEM wires, so while they cost a little less, they're identical to the OEMs. Or, if you're on a budget, Bosch is okay, but the price isn't that much less, so I'd stick with Bougicord. (FCPgroton is a good place for these items.) If I were you, I'd check out the "resources" thread, and do a "stage 0," (details are in that thread) so that you know where everything stands with your car.

I'm going to get this kit on FCPgroton for $170, it should straighten her out a bit. It runs a little rough and there is a little vibration on acceleration until the turbo kicks in.

Is there really a procedure to this...? I am new to Volvos and also turbos...go easy haha Oh and a tune up made a HUGE difference on my car.

What about exhaust? I don't want it to sound like a rice-burner, I want it to be throaty and roar, but not too loud. Any suggestions? Within reason, $200-400.
This 850R really puts a smile on my face, I really can't believe it when I gas it up around 40-45 mph and the tires break free, it's too much fun.
thanks

Yes they are fun now that mine is a manual tranny I had it chirp in 3rd gear taking off easy and getting on it after rolling. I am running 14 PSI boost as well.

The one I linked sounds good.
Here is a link to what I have. It is a 3 inch down pipe no cat and a dynomax muffler with dual tailpipes.
