'06 WRX Motor Swap - Installing a 2L EJ205

[LaszloT]

Hi,

We're interested in any of the challenges and considerations of this type of swap for our build planning.

We have a built EJ205 motor from an '04 WRX and we'd like to put it into an '06 WRX chassis. It's a stout-er motor with a higher redline

Our '06 WRX currently has a COBB turbo back exhaust, an STi turbo and a protune on the COBB Accessport, and 220,000 km on the odometer

1. EJ255 coming out is a 2.5L motor with AVCS on the intake cams
2. Plan would be to swap the long block and use all the EJ255 engine peripherals and accessories
3. I heard cam sensors are different

We'd appreciate your thoughts on any adaptations required, i.e. Non-AVCS motor will likely throw a CEL which we can turn off with the COBB AP

The WRX will be used for Autocross and a few lapping days each year.

Happy new year!

Oh, I should add that the car still runs well but is starting to consume oil
