Default alternator question

I searched but cannot seem to figure out if the 2010 wrx/sti 110amp alt will fit on an 02-05 2.5l n/a engine. I have big 3, grounding kit, and interstate megatron plus in the car and i am running a good bit of power so I want to upgrade from my 75amp alt and I will also be running a 2nd battery. I will be running about 3000w rms in my car.

The fact of the matter is you're going to need a lot more than a 110amp alt for 3000rms :/

I figured I was looking at the maniac stuff but they never respond to emails. I was looking at their 140 and 160. I know the 140 only does 75 at idle and that isnt so great.
I have access to the 110amp right now, and I am only running 1500w rms and that should be plenty for now until I upgrade everything around tax time to 3000w rms.

I mean if you've got the alt, may as well go for it. Unless you get something custom wound, I think the maniac alts are about your only choice. Unfortunate that they haven't been responsive....one of those guys posts here occasionally.

I have access for $50 that is why I was wondering if the 2010 110amp fits the 02-05 2.5rs engines. There are actually more options Singer makes a 200amp comes with an upgraded pulley to get some power at idle, dc power makes some big boys, mechman makes a 105amp(sure they can do bigger), and I think HO makes one.
