    Engine Swap for 2003 WRX

    I realize this isn't exactly a build but I'm swapping my motor in a couple months and I had some questions. Can anyone give me an idea of the complications you run into if you drop in the 2.5L instead of the 2.0? I've heard you have to swap the peddle assembly but it wasn't from the best source. Any suggestions on the best place to get a new motor or long block for a reasonable price? And last, has anyone ever bought a motor from engine land inc. in Montreal?

    -Thank you fro your help.

    I did that swap to my 2002 back in 2009, or rather, I paid a pro to do it. I've done turbo swaps, pipe installs, etc, but decided to let this messiness be done by somone else.
    No pedal swap involved with my EJ25; he reworked my 2.0 heads/valves, and reused all of the "top end" parts, so it all just kinda went back together and was ready for a tune, if memory serves. I was using a crate short block, and non-stock parts for turbo, injectors, and intercooler.

    It's been a while, I may be forgetting something.

    Do something about the compression ratio.. whether it be chamber matching the heads, thicker gasket, or hybrid pistons. Other than that, make sure you don't use head gaskets made for a 2L.. and you're going to need a custom tune.

    It is less fiscally responsible to "drop in" a 2.5 vs. building a hybrid motor.
