What is causing my car to blow smoke?

Anyway, under normal driving conditions (Idling, Normal take offs) the car blows no visible smoke. But with fast take offs the car sometimes blows quite a bit of smoke. The smoke looks brown.
If im just driving in second/third gear, then flatten it (to redline) it wont blow much, if any smoke. Its only really if i take off from first that it does.
Compression seems to be ok, (i checked it, then put some oil in the cylinder and rechecked it, and not much change in PSI).
It doesnt seem to use any engine oil (I regularly check oil, and always at the same level)
I also stopped using Flash lube (as i thought this could maybe minimise smoke) but same still. If i damage the head i will just get hardned seats.
Also, a few months ago, the turbo started to blow a LOT of smoke, and all the time. But that was blue smoke. I got a bush and seal kit for it, and did a basic rebuild of it then it stopped blowing blue smoke.
The car has always blown smoke on fast take offs (for the 10 or so months ive owned it), and it hasnt got any worse.
What could it be?

blue is oil
I would normally say fuel is black smoke but then again with modern fuels this may not be the case.

you will most likely feel the car bog down when it hits the rich spot

Also, totally un-related.. But does anyone know how shit it feels goin from an LSD to an open centre? I couldnt find a replacement LSD, or centre (well not without spending $1000+) so just stuck in standard banjo. Complete garbage to drive. I took off from the lights near my place the other day and its on a slight up hill and one tyre was spinning for what felt like a couple hundred meters. Thru 1st, 2nd, 3rd...

Fuel is normally black.
You get the same on the dyno if the car isn't normally taken to full noise.

I think smoke colours are still the same with the unleaded fuels, only difference seems to be you don't get that nice white/light grey exhaust after a long trip.

I'd go somewhere with either a gas analyser and/or a dyno and get a good tune.
Best of luck!
