Default EJ20tt swap In a 2002 auto wrx

Hey guys,
i know that im going to get a lot of blow back for posting this, but i need to know some hard facts, not speculation on swapping the legacy motor into a wrx. Ihave read a lot of the second turbo running into the steering colum, but i have seen the youtube video of the rs that has the motor in and its left hand drive. I plan on going standalone with AEM or can i use the fatory harness with a reflash. I would really appretiate constuctive replies, but if you want to discourage, please reply somewhere else. thanks

Factory harness will not run it. With AEM your tuner will hate you. 15 year old engine. Save your money is the only words of encouragement I can give.

In order to do a JDM Subaru factory made twin turbo on any subaru the brake master cylinder needs to be on the passenger side of the car/engine bay. So I belive that u have to have a right hand drive subaru or; dash, pedals and steering. The second turbo goes in the same place as the brake master cylinder here in the US.

The only twin turbo engine that will work is an EJ208. You can use both your WRX intake and exhaust manifold. Of course then it wont be twin turbo anymore....and thats a good thing

Is there any particular reason you want to swap to this motor?

As someone who has swapped one of these motors into an older Impreza (I believe it's only been done once, maybe twice) - putting it in your WRX will make your car run like absolute ****. There is no reason to put it in your car. Your car will be hard (if not impossible) to tune, it won't pass emissions, you'll lose power and reliability.
The transmission, however, is very nice. Well, it can be depending on which model you get. But the EJ20R, if I recall correctly, had 50/50 AWD and a LSD. That might be worth swapping.
But the engine is pointless on any post-98 USDM Subaru, let alone a WRX.

Totally different ballgame. OP is talking about keeping it twin turbo on a much newer car than yours that came turbocharged from the factory.

change the brake booster to a smaller aftermarket one and it will clear the primary turbo

after looking at the dates i know im late but here is the deal with a tt in a wrx i have a 2004 wrx same as your 2002 it can be done and honestly its not as bad as everyone seems to think!!! yes every one is rite the steering will not fit yes the bosster wont fit and yes the downpipe doess not fit.....and i read all of this befor i bouught the engine it didnt scare me one bit the tricky part was the uppipe no one ever mentions the up pipe and the go and return oil feed lines for the turbo,, i built the uppipe downs pipe rerouted the oil feed lines and boom i have steering the booster every one told me buy a small after market one,swap it out with a justy booster bla bla bla as i read the coments i seen that if no one knew that the uppipe wouldnt fit they knew nothing about this swap so what i did was saved my time and money and just cut the booster and rewelded it to fit the turbo and downpipe...it was alot of work and was it worth it YES IT WAS it cost me 600$for the engine i used my old transmision and clutch system and i used old metal tubing i had at the shop off old exhaust i had kepted and the ful swap took me 4 days and it was ready to have it sent out for the wiering so realy i saved about 1500$and gained more power and the one that makes me the happyest is if and when i spin out another rod!!!!it will only cost 600 to fix
