EJ20TT, Need some info, and Wiring Diagram

Hi im currently working on a project, of putting in a Japanese Spec EJ20TT engine into a 914 Porche, what i need to know is what car the engine originally came in, what type of performance parts are availible,and any other helpful info. Also if any one has, or knows where i could get a wiring diagram for the computer and engine harness. Any info would be helpful, because this is my first venture with a Subaru, but I think it will be a neat car since the 914 weights only about 2000 pounds and the TT engine supposedly produces 325 horsepower (280 rated, but i heard it is more like 325).

I REALLY NEED A WIRING DIAGRAM PLEASE HELP IF YOU HAVE ONE OR KNOW WHERE TO GET ONE.

EJ20 twin turbo was from 2nd gen (BG5) and 3rd gen (BH5) Legacy Wagon GT-B, or B4 RSK (BE5)

You need to know exactly what year and what model your car motor is because Subaru changes wiring pretty much every year on every model.
I believe the engine codes on 2nd gen is EJ20R (could be EJ20H)
and 3rd gen was EJ208.

Usually there is a sticker on timing belt cover with serial number.
Post that number.
Also post a pic if you can, it's really hard to tell though.

I can get you the wiring diagram from Japan, once you know exactly what you have. of course it's in Japanese but it's better than nothing
