OK, I haven't pulled the overheated engine on my '02 WRX, but planning for the worst. A couple quick questions, since a EJ257 swap seems to be the way to go:
Do I need to upgrade to the STi injectors or is there enough headroom in the 2L injectors to work with the larger displacement? Obviously a tune is necessary.
How does the displacement bump affect turbocharger behavior? I haven't dug around for compressor maps or anything like that, but am I correct in assuming that the larger displacement won't cause compressor surge or over-rev the turbo?
