I think just about everything turbo will be a "hassle" you need to swap x-members and stuff but its all do-able.

Not sure about the harness differences, but im assuming its quite different between NA/Turbo cars.

It has it's ups and downs. I did this exact swap

Expect everything to cost more and be longer than planned. It took me 6 months to do mine. The wiring was the biggest problem to tackle for me.

I'm not sure what you're really asking. Practical way all depends on your skill level/available time/money. If you're mechanically inclined, go for it. If not, well it will cost quite a bit to have it done. All in all, I'm glad I did this. I learned a ton doing it, and will probably swap something else like this later in life.

Agreed. Don't swap if you're doing it for money purposes. Do it if you love the work.

One of the easiest Subaru swaps there is. Not a single wire needs to be cut and spliced because you've already got a GD chassis. Just get a complete Ej205 engine swap with uncut wiring harness and replace it in your car.

But why do just a WRX? If you are putting 40 hours of labor into your car, either add in an Ej257 shortblock swap at the same time, or get a complete 04-05 STi swap. For the trouble there's no reason you shouldn't be running 2.5l of displacement.

bump an old thread:

this is the swap im doing, and i havent heard anywhere else that it is a plug n play swap. do you mean just engine wiring harness uncut, and the bulk head harness from the rs will plug into a wrx ecu?
im looking at wiring diagrams right now and they look very different....
