Default TUBRO (yeah i spellit weird) HELP! PLZZZL

Hey I have an 89 turbo and it runs but the turbo doesnt seem to. On the road tho sometimes the stock gauge would jump to 8 psi. It sits on the 0 when driving and -4 when its idling. ALso it puffs out random white smoke and it runs absolutely perfect otherwise!!?? ANy suggestions? Thanks

Correct me if I'm wrong, but that sounds like the way a stock turbo is supposed to act. At idle it has negative pressure, no exhaust pushing the turbo. At normal driving to slow acceleration it could be 0-4psi and under full acceleration hit 6-8psi?

Does the car feel like its under boost when you accel or does it feel boggy and slow? could just be a bad gauge.

Do a diag

http://www.toyota-supra.info/forums/...read.php?t=323

From what I've read from other posts here my might have a vacuum leak somewhere. If I had a turbo I'd be of more help but I'm just a N/A

does it feel like its boosting normal when you hit the accel or when you hit the accell you get no boost?

I had already done a diag and it came up a 52 (knock sensor) and that was all.

Also the car is not boosting wat so ever.

The white smoke could also indicate a BHG or shot turbo. lol. And try to borrow a friends boost gauge, one with a vaccum line, or just go buy a cheap one, The stock ones are known to suck.
