not boosting much

my zed isnt boosting up enough, i had some small vac leaks. could one of my turbos blown? if so how can i tell? how much dose a second hand turbo cost (ive had a look, but after your opinion)

thanks

 

How much is "not much". Check that all your engine electricals are working and look for any other leaks before assuming it's blown turbos. Might have ECU error codes too, so do an ecu diag as per tech articles.

If you want to tell if it IS the turbos, check for blue smoke coming out of the exhaust

 

Blue smoke is Fuel andrew...
white smoke is turbo seals
black smoke is oil

you want to be looking for white smoke.....

 

Incorrect....

Black exhaust is usually excess fuel.

White exhaust is usually bucketloads of excess fuel (hard to start), or water vapour.

Grey smoke is usually oil (like in a two stroke)

 

im so confused lol i dont think its turbos the car is running fine (no smells, noise, still handles right) just no boost

thanks for the info though will have a look for smoke =)

 

My money is on ''boost leak''.....

The number one cause for lack of boost in a ttzed is a vacuum/boost leak. Sometimes very hard to track down because there is so many possibilities, but the ONLY way to check is by way of a "boost leak test".

You might spend a whole day tracking down and rectifying all your leaks, but if you don't do it..... you'll only end up "chasing your tail" trying to get your zed running properly

 

i have just started to notice blue smoke and a bit of a smell had a quick look on the side of the road today and there might be a small hole in one of the mufflers

 

well hopefully get everything running smoothly in the next month or two =)

 

check ur coil packs and connectors leading to the spark plugs. if they haven't been cleaned they will most likely have this green corroding crap in there. also check spark plugs they may need replacing. and make sure all cylinders are firing.
