The 99-01 Altima alternator is a 100A unit. As a cheap easy upgrade, it's a nice choice. It's good to hear that it swaps straight in and it's probably a better fit for most people.<br><br>In my case, my car is a rally car, and when the lightbar is mounted and on, it will be drawing over 60A in lighting alone, so I didn't even look at the Altima units.<br>
<br>I swapped the pulley not because I had to to make it fit, but because the smaller Maxima/Altima pulley (both use a 63mm pulley), compared to the 70mm pulley on the Sentra would have meant that the alternator would be overdriven. Besides taking a bit more power from the engine, I was concerned that long-duration high rpm situations (like my car will see) would burn out the alternator.<br>

<div><font face="Arial" size="2">I swapped in a 99-01 altima alternator into my NX.
I read on the sr20forum that it outputs 120 amps, although i was unable to
confirm that. However, the installation was straight forward. It was a direct
swap, I didnt even swap the pulley. The altima alternator housing is slightly
larger than an sr20 alternator housing. The pulley on the altima alty is smaller
in diameter than the NX2K alternator, but it falls in line with the sr20 drive
belts. I still have the stock pulley just incase something unfotunate happens
down the line. I have had it on for several months without issue. I picked it up
at a local junkyard for $50.</font></div>
<div><font face="Arial" size="2">The maxima alternator sounds like alot more work,
since all of the connectors on the altima alty are exactly the same as the sr20
alternator.</font></div>
