Screeching On Start Up

[warzone]

Well this is my first post here, and decided to sign up after lurking for a little while and reading some useful posts, I bought my dream car a few months ago and it's a beauty, 1999 Skyline GT-T manual =) But I have a problem or two that I would like advice on if possible.

- On start up - the car screeches quite loudly, and then stops after about 1-2 seconds and you never hear it again until starting up again (it seems like the warmer the car is, the less screeching is heard) - I had it serviced last week and they stated it was the starter motor as they checked the belts/tightened etc. I'm attempting to find a starter motor for my car but am having trouble, is there any specific place to look or is there another possible reason for the screeching?

- Second issue I have is, the turbo has quite a noticeable whine when it spools - At first I thought it was maybe a hose leak but once again Autotune stated they checked and tightened the hoses (but I am not all that convinced). I tried reading on the whole "whining" noise of a turbo, and some people state it's normal and some state they are worried - I feel like I get good boost so not sure what's causing it.

Thanks for the input in advance.

Oh and one other note - where would be a relatively cheap place to get serviced in VIC (melb - northern suburbs).

Ps. Attached pic since I am new here =)

the screech, if not a belt squeal, may be the starter motor sticking and not disengaging properly once you let the key go.

as for the turbo whine, it's not just the usual induction noise that you are hearing? maybe google a few videos on youtube of turbos spooling to see if any have a similar noise to yours

As mad082 has said; It could be the starter, often clutch dust etc, makes the starter shaft sticky, and causes the pinion to stick in the thrown out position, and if it stays engaged with the ring gear, you'll get a hell of a racket.

Flushing the starter shaft with contact cleaner will remove the stickiness, and no more screech. Opinions differ on whether a small amount of lube on the pinion shaft improves or exacerbates the issue in the long term.

Also; just "tightening"the belts is not always enough.

The tapered section of the belt lands use a "wedging" action in the pulley, even if the belt is not visibly cracked; the belt can wear to the point that the valleys of the belt can rest against the peaks of the pulley. You then lose the wedging action, and this will cause the belt to slip.
