help a brother out

Looking at a car for a friend 91 Laser RS turbo. the car seems to run pretty good except the bastard won't make any boost. I did the easy things to check waste gate arm, 0 shaft play and the wheel spun freely. I could spin it with my finger and it would keep spinning for a few seconds on it's own. I'm beginning to be at a loss here. The car is REALLY cheap and would make a great driver for my friend. Could anyone please suggest a few other things to try before we say to hell with it. Also one last thing I just thought of the car doesn't smoke at all so that along with the turbine being seemingly good I dont think it's blown.

thanks very much

check all the clamps on the intercooler pipes, it could just have a really bad boost leak somewhere... you could do a boost leak check too. vfaq.com will help you with that

Sounds like a boost leak also. Are you hearing th BOV at all?

no bov what so ever. thought about boost leaks as well the ic piping seemed ok but I will go back over them again to make sure.

Although the the actuator arm is attached doesn't mean that the flapper is fully closed. Remove the arm and make sure the flapper is fully closed when the arm is re-attached. Check for any major exhaust leak before o2 housing, wouldn't hurt to bring a compression tester on your next trip. I also think boost leak is a good possibility as well.
