The stock 2g alternator puts out 75 amps for US models (Canadian are 90 amps).

Heres some vfaq info:

There are some indications in the archives that the 90 amp alternator is the same as the 75 amp U.S. stock alternator, except it is rated for 90A. (Read about this here.) Wes Grueninger asserts that the two alternators are, in fact, different, with the 90A having an extra output tap attached to the wye terminal in the diode rectifier pack. In any case, the 90A alternator has a rated minimum output of 50A, with a 90A typical output rating. Even Canadian DSMers complain that the alternator on the car is undersized.

For auto owners, Kyle Zingg posted that the alternator for the auto cars has a different part number, at least for 1Gs. The part number for the 1G auto alternator is MD153843. Manual owners have the same alternator on both the turbo and 2.0L non-turbo engines. It has also been reported that 1G and 2G alternators are the same aside from the actual output plug, which can be swapped.

I have the 1999 Mitsu Eclipse service manual and it says for the NT the alternator is 90A part #M04661998 (the 2.0 turbo is 75A part #MD313392 for M/T and #MD327513 for A/T).
