Im planning on adding an additional 12v battery to my Myo4 wrx. After researching alternators ive found mine to be a 75 amp output with a three phase y plug. I have found that the forrester alternators are higher rated for the added kit and some are rated upto 110 amp ie the 2.5 of similar age. Can anybody confirm if the forrester engine bay layout is the same as an impreza wrx to save me the time of ordering wrong parts. I have looked on the forrester site and have seen some people mentioning they have used alternators of impreza's but not sure what year and models are compatible.
Any help would be much appreciated as i want to get on with the install asap.

 

Since it's the same engine, I'd THINK the alternator would fit the same way.

Can you not Google a pic of a Forrester engine bay?

 

Looks the same from the pictures i can find, was hoping to find some1 who know for sure to save the hassle of returning parts.

 

I know the STI ones are 90 amps (newage) though not sure about the forrester ones (or the legacy ones).
I would also price them up, you will be in for a shock at how much they cost
