I'm putting a 1.8 vtec out of an integra in my escort. Out of curiosity I put the tape across the bay in my mk5 zetec s and it would go straight in. The shape of the wings even lends it's self to using the original mounts.

Standard lump will return a solid 280bhp with a low boost turbo reliably.

Seen a few folk running 350 ish on standard internals.
