ej22e to ej25de swap

[parkcityboyx]

has anyone had any experience with this kind of a swap? im aiming to put a ej25de into my legacy brighton that originally had a ej22e.

i do know that there will be some difficult wiring, and it would be best to get the ej25 ECU as well as sensors. but i also know theres some other things that i will have to do.

if ANYONE knows has experience with this swap, or any type of counseling before i start the project, PLEASE do not hesitate to put some say in. i dont care if your completely honest with me and im being a retard and forgetting something :smt021 just help me :grin:

thank you guys so much

just dive in....

rarely a motor swap goes exactly as planed. between the 2.2 and 2.5 it is a fairly easy swap.

might find differences in connectors etc, but its all work around-able...

cheers.

The EJ25DE is not the best choice for a North American swap. Assuming your talking about the JDM Forester DOHC 2.5ltr.

"Yes the JDM ej25de fits right in. All you need to use is all of your outer parts (intake, injectors etc). Make sure the jdm engine has the egr return -->drilled and tap<-- ..."

North American N/A EJ's are a simple process:
-motor is re-and-re (every EJ motor is identical, all mount points are the same)
-use the ECU that comes with original car.
-charcoal canister may be located differently depending on EJ25 you choose.

I'v helped a few friends do EJ22 -> EJ25D. Its not that bad everything is plug-and-play with little modification/massaging.

IMHO:

"The difference between the DOHC and SOHC is not all that great. SOHC has more torque while the DOHC has more top end pull. The difference is so small that it could boil down to port design or just a matter of ECU tune that was put on the car. Nothing really to do with the number of cams or anything like that.

The SOHC is simple to work on, where the DOHC requires a bit more attention to detail during timing belt changes or headgasket changes. I would go with a SOHC motor
for that reason alone." - NASIOC

2.5RS motors 02'+ is a nice clean motor. No real issues and very reliable. But hey its your money your choice.

Good luck
