Alternator part number

Hi there,
Could you please provide me with the alternator part number for a 1992 MR2 Turbo. Thank you so much in advance.

If your car is prior to 11/92, it's 27060-74330
 
If it's from 11/92 on, it's 27060-74440
 

Thank you so much!

Is there an easy way to tell which alternator is on the car (they all look the same to me)? I do have a 12/90 n/a converted to an early 93 turbo...

Alex, I think from memory, the earlier ones had a Square plug housing on the alternator & the later models (post 92) had a Round plug housing.

Not quite right.
Early SW20 alternators had a round plug, while later ones had an oval plug.
 
Also note that the NA alts mostly were 80 amp while the turbos were 90 amp.
Another difference between them is the turbo alts have wider bolt spacing and won't fit the NA mounting brackets -Something to be aware of if you were looking for a replacement.
 

Ok my 15yr old got the alternator out in an hour and a bit. The only thing that stumped him was when he removed the main mounting bolt last thing, the alternator wouldn't come down towards him. I thought the 2 brackets might have been tight and we tapped it a piece of wood and a hammer but no good.
So I got under the car and pushed the alternator upwards and it came out of the brackets and then through a gap and out the bottom.
Next Steve started to dismantle the alternator. It was fairly gunged up and some of the Phillips heads need tapping to free them. I showed him how impact drives are used. I think the bolts would have come loose by tapping a screwdriver, since we barely hit the impact. Anyway stopped when we got the brush holder off and one of the brushes was worn down signif. So took it to Bill Buckle's. The parts guy asked for the original Jap vin, not the import numbers assigned when brought n to Aus. Went home found the original frame number and rang it through - will be here in the morning.!! Wow!!
 So there was some correlation between the Import listings (which did not list the part) and the local listing which did. So he was able to match up the right part. I imagine we'll have it all back in the car tomorrow night. All up a couple of hours or learning for my son and I'm very confident, no more charging light coming on.
Before we started, many threads were saying too hard, exchange it etc. Our experience has been the exact opposite, even deciding to dismantle the alternator itself was simple. Mind you we took the alternator out the bottom with the car up on stands. Think we saved a few hundred $$.

Congrats on tackling the job.
 
BTW, it was mentioned that it was 'pretty gunged up'
Can be caused by a leaking cam cover gasket, when the oil drips down and into the alternator.

I've got a 1990 turbo.  Lithia Toyota quotes the Alternator part number as 270607418084 and it's only USD 211 (plus delivery) vs jp-carparts.com part number 27060-74330 which equates to over USD 1,500 (plus delivery).
 
Can anyone shed any light on the correct part number?  Maybe I'm just reading something wrong?  The Lithia link is below.  
 
Thanks for any and all help with the part number.
 
Cheers
Colin

Oh Crap, I forgot to update what happened.
My son pulled the alternator out from underneath (I think it may have to go upwards a bit first) - 30 mins.
Pulled the brushes out - 10 mins - took them to the Toyota dealer who did all the partnumber work.
Next day new brushes  - installed into the alternator - 10 mins - then 30 mins fiddling to replace the alternator,
 which was fiddly trying to line the holes up etc, 2 man job had it quickly  sorted. All up cost $15.
My son seems to be winning at each of the tasks I give him.
He just pulled the driver's seat out and got stuck into reconditioning the leather - looks great now - all the white wear marks are blacked again.
