Hello,

New to the forum so any help will be much appreciated. I have a 1995 850 turbo. I recently had to replace the cam sensor and noticed that my top-side intercooler hose was blown out. I had not seen any boost problems but did think the car was a little sluggish. I have now replaced the hose and now the car has got a lot of power but now the boost gage is going off the charts. As soon as I noticed it I have been careful to keep it in a safe range while driving, but I would like to know why it is over boosting. I read a couple of forums and have checked for broken or unplugged vacuum lines and I actually did find two that were off, but even after putting them back in place, I still have the over boost problem.... although it is not as severe now. I guess it is possible that I still have a bad vacuum line somewhere, but I do not have a diagram to go by. I am getting good "blow off" as I can hear it after acceleration. Are there any specific symptoms for either the actuator hose or the boost solenoid?

I know I just threw a lot our there, but I am just trying to narrow this problem down. Thanks in advance for any advice.

 

Wastegate actuator.

 

That is the actual wastegate right? Any suggestions on where I can pick one up for a decent price? Are the wastegates on the 850 external? Would it be better to pick up an aftermarket model for better performance?

thanks again

 

Did you connect the hoses to the EBC properly?
