hey fellas noticed this for a week now after returning from work and starting the car to go home from the station the car lets out a little puff of smoke and then nothing
but when i drve it and floor the car and it comes on boost i can see smoke in the rear view mirror but cant really tell what colour as its night time by then looks like blackish grey smoke
are my turbos on the way out
the turbos have a loud squeal and lets outthis hissing/whistling noise when let go off the accelerator after flooring it

The first puff of smoke would be your valve stem seals... the smoke coming from the car when you accelerate is FAIRLY normal depending on how much there is... remember that turbo cars are dirty cars - then theres the squeeling! i don't like the sound of that at all

Yup it sounds like the valve stem seals are starting to go.
I wouldn't worry about it too much, just keep an eye on your oil level. If your really concerned, you could get them replaced. I think they cost about $8 each from toyota multiplied by 24 valves gives you close on $200 just for the seals. Most mechanics will want to remove the head to do it, meaning more gaskets, lots of time and while the head is off you may as well get it serviced and the valves lapped. Don't expect too much change from $1K.
Or as I said earlier, don't worry about it. It will only be noticeable as a puff of smoke on startup for a couple of years. Just make sure all thoes little puffs don't result in an empty sump.

If it is just the valve stems, don't panic, I drove around for 18 months on my last 1G with leaking valve stems. It is just a sign of the engine ageing. If you don't mind a puff of smoke on startup then don't worry about it. If you do, then fix it. The joys of owning an old car mate.
If your seals are just starting to go, then you probably wouldn't notice the small amount of oil loss, so just do your normal oil checks and you shouldn't have to worry any more.
The "smoke" on boost is probably just the engine running rich and it would have done this since new and you haven't noticed until now. It may be your turbo oil seals but we can't tell unless we see it.
If you are concerned, why not take it to a mechanic and get him/her to look at it. They are not all evil you know.

Just to add my 2c 
My 89 GZ20 Soarer with 1G-GTE does basically exactly the same... a puff of blue smoke when I start it up, resulting in need a litre every couple of weeks. And when I floor it I get clouds of brown/black smoke out the back and my rear bumper is caked in SHITE... REALLY annoying :\
I'm in the process of trying to solve the soot issue as I don't think its natural, so I'll try and let you know how I get on... as for the valve stem seals, well fuck it, 1k is coilovers and I know which I'd rather spend 1k on

With regards to the blue smoke at start up, its a puff of blue smoke as soon as I start the car (definite blue, not white) and if I drive it straight up the driveway it'll puff more blue smoke out, but once its warmed up a bit and got the oil circulating it stops smoking blue (only about 20-30 seconds till it stops)
The other thing I've noticed is after a fresh oil change it doesn't do it, but as I'm changing my oil about every 4000kms I'm not gonna change more frequently just for that... just means I ahve to top up every fortnight in between changes...
My car had only done 113,000kms when I picked it up, although I suspect its been deregistered and re registered so probably was sitting around for a year doing nothing which wouldn't have helped the seals at all...

I assume that you have the boost wound up! If you get the car on the dyno you will find that at boost levels above 9-10psi the thing starts to run so rich it does not matter. Mine was in the order of 10.5 air/fuel ratio. The black smoke is unburnt fuel. While I am not recommending that you just go ahead and just do this - I found that by disconnecting the vacuum/boost line to the 'rising rate' fuel regulator I was able to achieve better air/fuel ratios. I did this on a dyno to confirm that the car was not leaning out anywhere. Not only did the car put out 10kw more at the wheels the driveability was vastly improved. As I said make sure that you check the result on a dyno.

some things wrong! First place to look would be fuel pressure.

well im thinking of doing something soon ,
the first puff of smoke is defenitly blue , the other i cant really see as im driving , ad looks very much blackish brown
im thinking of getting a safc soon so i will get itdynoed and tuned then
car runs ok otherwise
i have als noticed sometimes usually at cold running temperature at standstill the car sorta gets a bit stuck when taking off at the lights , u can feel the car sluggish only very tiny bit , then takes off , it happens only for the first 1/2 a second or so when taking off after a perfect standstill
nly if i take off very slow can u notice it , if the car is given enuf juice it goes as normal

Try using a slightly thicker oil... fully synthetics can be quite thin (e.g. 5W30)... If you use a really thin oil with slightly crap vss's you will smoke more

ya ive been from 5w-50 , to 10w-50
no im going to 15 w cause i think that will suit my old car better
fully synthetic is too thin for a 1988 model car as well as the car wasnt made to run on them anyway
thanks

On an interesting note, now that I've done my manual conversion the car doesn't seem to smoke as much when I floor it. Albeit the battery was disconnected for 3 days so perhaps an ECU reset fixed the problem. Also I haven't directly wound the boost up, its a Gen 3 1G-GTE so 11psi standard anyway, with 3" exhaust and no filter. If I get a chance to dyno it I'll try disconnecting the vacuum line to the FPR... I am however planning to install a boost kit and get around 1bar (maybe a little higher for testing *evil grin*) but we'll see how I go, I want it on the dyno once I've done that to check where optimal boost level will be...
