Hi my 300zx tt has been stood for about 2years now i hav started it but turbo nedle is not moveing :cry: dos that mean that turbos are jamed our some thin? can this happin or could it just be the nedle, Is there anyway i can check that turbo are working (need to sort this out coz summer is coming :hyper: ) would b greatfull for any help :nana2:

HAve you driven it? If so, how fast id it, no turbos working = not fast, look at your pipes feeding the boost gauge, But you wont get boost just reving it anyway, it will only show vacume.

to tell u the truth i havnt driven it yet as i said just started it. so nedle only moves when u drive it yes?

Not true, when not running boost guage should read zero (middle of guage). When you start the engine (idling) it should read negative values. Revving the engine slightly should cause the needle to move slightly. However, you won't be able to generate boost (positive numbers) unless there is load on the engine, ie you are moving.

 

If your boost guage is not moving at all then I would suspect a problem with the guage before assuming your turbos are dead. Even if both your turbos have siezed then the boost guage should still read negative values at idle.

 

Hope this helps.

mine did the sam when the pipe fell off my boost guage. probally hose related

well its not moving at all so i guess ur right rory any idea where i can find this boost guage pipe? and the car is a 1993 uk twin turbo manual and it has 80000 miles on clock with fsh how many milse these stock turbos last?

My tubs were still OK at 105k miles before I had them replaced (upgraded) for piece of mind. If you've been stood for a while, there is a chance that the smaller rubber pipes that feeds into a little black box toward the back left of the engine bay (drivers side) has perished or fallen off (happened to me).

dos anyone hav a pic of this turbo boost gauge pipe i mean where it gose and where it comes from? thanks

The one that came off mine was on top of the engine, towards the left a bit, just look for a pipe thats OFF. And see if there is a tube near for it to go on.

thanks mark will hav a look

My Turbos worked well up to 130,000. Then one went big style hence complete engine replacement with upgraded lump and roller bearing T28's. So you got a while to go yet. Just change the oil frequently.

thanks had a look at this small box and pipe in engine it seems ok im going to hav a look in dash coz had immoblizer removed they must have done some thin there while they were doing that mean while if anyone can think of some thin alse give us shout thanks to all of u for help
