Hi,
I've seen it done once before to a mk6 escort (95-2000).
A large section of the slam panel had to be chopped out to fit it.
I'd advise a 2L zetec transplant. Mine (standard) recorded a 15.7 @ Santa Pod yesterday.
If you want more serious performance, then a 2.3 converted RS2000, or a zetec turbo are the ways forward.
Ralph.
