White smoke

[Charged1]

Hi I have a GTZ turbo conversion , and have recently had the turbo fully rebuilt but now under hard exceleration I get white smoke blowing out the back , any ideas what might be packing up now , have had no loss in power at this stage , cheers

White smoke is lean. IE you need to feed the engine more fuel, either by modifying your map, by increasing your injector sizing or by increasing the pressure in the rail.

I'm no expert on smoke signals but my Boy Scout book has a page on this topic:

Chief Screaming Engine says that
"Heap White Smoke Sometimes Means Something Inside Engine Wants To Surrender"

Common car smoke signals:
Blue = oil
Black = running uber rich
White = steam = Water getting in - usually due to BHG (unusual for a 4AGZE)
Brown = running lean (nitrous oxide)

Sounds like ya motor aint so good.

Would suggest a leakdown test to see where the prob is

white can also mean brake fluid in fuel

no not all of them have them you need the ask.
get a cylinder leakage test tells you whats happening normal.
conpression test tells you only compression not much really but if there out by heaps something wrong.
