A quick question about 2g ALTERNATORS

[-DSM2NR-]

are all the 2g turbo alternators the same and can I, for example, put a 99' turbo automatic alternator on my 95' turbo manual dsm?

 

[4BangR-x]

yes siir

 

[-DSM2NR-]

can somebody confirm this please

Well, according to my research all 2G turbo alternators are the same, rated at 90 amps.

But when I check online auto parts pages (Like http://www.autopartspeople.com or https://www.mitsubishiparts.com/oe_parts_catalog.html ) they classify the alternator for the 2G turbo in 95-97 and 97-99.

But I'm pretty sure they are all the same.

The 1g autos are different then 1g manuals, but the 1g manuals are the same as the 2g manuals turbo or n/t. 2g autos are the same as 2g manuals. USA spec alts are 75 amp and Canadian spec is 90 amp, i know there is a how to on this mod somewhere.

all 2g's are 90amp alternators.
there is no fancy canadian model, they're identical just labled differently.

With some more searching I found some useful stuff from 1111 AAQ

Has anybody ever converted their U.S. spec (75 amp) alternator to a Canadian spec. (90 amp) alternator?
Search for this topic now!

This is possible, and the Canadian part is a direct bolt-on. Some dealerships may get confused over what you are asking for, however. You may be able to get around this by ordering a Galant VR-4 alternator instead - it is also 90A and will bolt right on.

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.

Read this post by Gary Selph for a description of possible alternator replacement options, including the Mitsubishi part number for the Canadian alternator. Also read Dean's Daily Discussions #8 for a little encouragement on how simple the replacement process should be.

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.

It has been reported that Mitsu alternators rotate in the opposite direction of most alternators, making aftermarket units problematic. Read about this here. For this reason it is possible that aftermarket parts may not ventilate correctly, leading to premature failure.

Manual owners have the same alternator on both the turbo and 2.0L non-turbo engines.

Not true on the 1G's, the N/T have a 65 amp alternator and the turbo versions the 75 amp alternator.

ok, so the main point here is that any 2g turbo alternator (whether auto or manual) will fit on any other 2g turbo model, correct?

Thanks for the help guys, especially 4BangR. Sorry but I can't give you any more REP since I gave you some on a previous thread already

 

[mn95TSi]

should fit, the amperage may be different though.

while trying to get new ones from autozone- ive end'd up with 3 differant ones.
Its prob just because there system is Eff'ed up

yeah, I'm running an Autozone one right now and it seems like it's already messed up (only 500miles after installation).

I don't want to go through the same route again and replace it with another Autozone one so I decided to go OEM.
