Legacy US Legacy 2.5GT to EJ20 TT JDM

Currently doing a swap. Have a Legacy 2.5GT body with a 2.2 replacement motor in it. As far as I know it was straight plug n play with all wiring harness's so its still stock. Recently picked up a EJ20TT JDM for a decent price. But I have not been able to find wiring diagrams for the JDM engine.

I am really looking for a good wiring diagram for the Japan motor/fusebox/ecu ect. the actual motor installation wont be a problem. I can do the installation/fab/mechanical converstions. I just want an accurate diagram on wiring so I don't fry anything lol!

Any info/diagrams/tips would be very greatly appreciated! Thanks in advance and thanks for these great forums!!

First off figure out exactly what you have. There is no such thing as an "EJ20TT"

You could have anything from an old EJ20R to a newer EJ208

If I recall correctly, the twin-turbo JDM motor can only be used in a right-hand-drive chassis, due to the way the steering column interferes with the secondary turbo on a left-hand-drive car.

There's a reason those engines are so cheap...
Like cartwheels4amile said, the engine won't fit in a LHD car because of all the steering gubbins being in the way

Plus it is a severe downgrade from the EJ255.

Why? Because twinturbo?

So everyone ****s on this because of the LHD/RHD issues. Well I have a postal and am thinking of getting a BE front clip for 2k and doing the swap. Can some one tell me why I shouldnt?

because the b4 has massive valley of death. they're sequential turbo's, not parallel. everyone i've ever known (and there's been a few of them over here in aus) have converted them to single turbo.

Why covert to single. From what I have read the VOD is because people can't shift? And what would be the point of doing the TT swap only to have to then go single. Seems like people just want to take the easy way out . I have been listening to the go single argument for years with the JZ/RB crowds. I have swapped to a big singled JZ car only after my twins started to smoke I don't care about subie big hp just want a fun daily.

4cyl engines split the exhaust pulses up too much for twin. especially boxer engines. 2jz's are 6cyl engines. you are comparing a 2jz to an ej20. you have no idea what you are talking about.

Nice, let's be condescending and insulting.

Where exactly did I compare anything?
I just made the point that I have hard the twin/single argument a number of times. Stop being a fourm bully I am too old to give a ****.
