EJ257 vs EJ255: the key difference

The EJ257 (STI) uses a semi-closed deck block that provides significantly more cylinder wall support under boost than the EJ255 (WRX) open-deck design. This makes the EJ257 the stronger foundation for higher-power builds. See the full comparison in our EJ255 vs EJ257 guide and EJ engine family guide.
