Just installed the engine forward portion of the racer x fmic and I can verify that it does not fit without some modifications.
You will need to do some cutting of the lower shroud and !metal surrounding it. In addition, and this is the big one - you will need a legacy gt front bumper beam or you will have to cut off the lower portion of the stock beam. I chose to cut off the lower portion of the stock beam. You also need to relocate that little sensor in front of the ac condenser.
The foam does not have to be cut, but I cut mine anyway.
I tried uploading an image but it must have been too large. If anyone needs to see what it looks like let me know and I'll resize and post from my pc.
