What would happen if you ran a car with the turbo off?

I am wondering because I may purchase a car that had its turbo stolen. I was wondering if I drove it a small distance (under a mile) if it would cuase any serious damage.

If yes, then once i hookup a new turbo how will I know that everything is working right and not damaging the engine. Can I just install it and start it? What could possibly happen if something is hooked up wrong? How will I know?
 
well let me begin with saying it isnt good at all. A turbo car pumps out alot of fuel so without that compressed air it will suck. I have had IC pipes blow and that is like running without the turbo and its no good. You wont be able to go faster than 15-25 mph and you could accelerate faster on a skateboard than a turbo car without the turbo....now if you change to fuel pressure it would be different. I say if you have more than a 1/2 mile tow it or push it, because making it able to drive normal without the turbo is too much trouble.
 
If it is around a mile that you are driving then why don't you just tow it. It will be faster and then you wont have to worry about doing any damage to the car.
 
Are you talking about an open exhaust, or something put in its place? If your O2 sensors are still working, the ECU will probably tune to accomodate, but if you're going without them, it'll go into limp mode.
 
When intercooler piping blows off it sucks driving a car more then 1000 feet. I dont know if it will be the same but it might.
 
after I put my aftermarket boost gauge in I took my car for a test drive just up the road, and on the way back I was about 100 yards from my driveway just hit max boost in 3rd gear and BAM, uicp blew off and I almost ate teh steering wheel! good thig there was no traffic coming so I could just coast the rest of the way. Just my 2 cents! :)

haha almost as bad as hitting fuel cut!!! wastefuldreamer IC piping coming off is cutting the turboout off the intake track. Plus I dont believ the ecu will accomadte too much.
 
The main thing you need to do is make sure when you put the new turbo in the car that you make sure all your water and oil fittings are secure. DO NOT reuse any of the banjo washers. You can but remember that the only thing worse than water all over the turbo is a nice oil fire. just make sure the fittings are secure and you should be ok. www.vfaq.com has what I used the first time I did a turbo install. I have done four of them now and no problems yet :)
