Whirring belt noise

[craz0]

Hi all I got my R33 GTST (auto) a week ago, it has 88400k's on the clock (well that's what the odo says) anyway after a a bit of a drive when I stop and shift it from drive to park it makes a bit of a whirring noise the noise sounds like its coming from around the timing belt area it only lasts about 15 to 20sec, the alt, ps and ac belts are all in good nick. But even when just sitting there and I move the Auto lever from park to reverse or to drive then back to park it makes the noise.

So I'm looking at changing the following:

Timing belt

Idler Bearing

Tensioner bearing

Crank & Cam seals

Water pump

Thermostat

It's a bit hard to describe the sound but what I'm mainly after is abit of info on, if anyone has done this of late and was able to give me a rough estimate on price and where is the best place to get these parts from?

Any help would be appreciated.

My car does this now too. Lots of cars do this. It's strange but it does no harm.
