According to the repair manual (see pic) the output of the generator should be 1680 watts. To convert watts to amps you have to divide by 12 volts: 1680 / 12 : 140 amps.... Thats should be the minimum...

 

Interesting reading about voltage regulator here : http://forums.pelicanparts.com/porsc...placement.html

and here http://www.renntech.org/forums/index..._1#entry178700

It can help reduce cost....

 

That one is specified for a tip, so I called the guy. He said I need this one, which isn't a Bosch but a direct replacement for the Bosch AL0812X that uses an OEM clutch pulley and a Bosch regulator. This does get confusing.

 

It is in fact very confusing. 120 amps again. I've read so many post now that I don't know what to think. Especially there is one on Renntech for installing a higher amps output one over 200 amps but no replied... I carry on my search and will let you know. Please let me know your outcome...

 

I agree the issue comes down to amps. if you go to autoparts websites most come up with a 120 amp version for our cars, but a few return a 150 amp one for a couple hundred more. When I had to replace a radiator a couple months ago I realized the parts places frequently list a part for a 996NA car as being compatible with a Turbo, when in many cases they require different parts.

Does anyone know the original Bosch part number for the 2001-2004 Turbo?

 

Yes! Agree with you. If you look at this one the advertise ti at 150 amps! http://cgi.ebay.com/ebaymotors/NEW-A...#ht_2918wt_941. I also went to many french site in europe and they are rating the TT alternator at 120 amps

I called Ryan at Suncoast and he gave me the Porsche p/n as 997-603-012-01, which is one of the interchange numbers from the link you provided above. He didn't know the Bosch p/n. BTW - a reman from them is $1,300!!

 

Bosche AL0812X will get you the 120 amp version.

Amperage requirements vary depending on load. If you have headlights, foglights, wipers, A/C on high, stereo blasting you may exceed the alternator's output thus will begin to deplete your battery. Otherwise there's no problem with 120 versus 140. With a voltmeter you can at least keep an eye on the situation if you see voltage down around 13 with the engine running.

Around $400 for a rebuild will get you a genuine Bosche rebuilt. Not a Bosche "like" alternator that "like" might work for "like" a little while. Some of the ebay stuff is major crap. It it's less than $400 it's a chinese knock-off.

 

I've had enough. I called Rare Electrical and spoke to a guy who seemed to know his stuff. He says the 150 amp model is for the 2005 Turbo MY and the 120 amp is for all the other 996 models and years. I bought one from them for $190. He was adamant that is the one I need.

 

Ouch! $1300.00! Glad we got internet to found some options...

Thanks also for the new english word I've learn today: "Adamant"

 

DANGER! Will Robinson. Very misleading ad, that one. It lists Porsche as an OEM for alternators. Never does mention the true manufacturer other than their part number, 0-124-525-057. Google that and all you find is the pulley. That's the part number for just the pulley. Now what about the rest of it?

You may get lucky with such crap, but you might fry your ECU as well.

 

Amazing how difficult it is just to save some money Over 29.000 feedbacks !!!! And only 31 bad ones....

 

Depends on the question you ask. Does it fit? Yes.

Is it a quality replacement for an exotic sports car? No.

Americans aren't difficult to please, cheap crap satisfies. What can I say? Look at the "Real Housewives" ratings. Who'd a guessed?

 

I ordered the cheap one and will report back on outcomes good or bad.

 

I know what you mean. I live not far from a Walmart... But I hope you understand that many times, parts prices for exotics cars are too high and it is possible to found cheapest alternate. Ex: oil filter, air filter... Pelican is offering alternate parts at better prices including alternators and starters etc. so far so good with what I purchase from them....
