does an s14 engine fit w/o modification in an s13?

[silviase]

Hey guys I was wondering if anyoe out there has ever put in an s14 eingine into an s13. If yes are there any
modifications that need to be done

not sure, but i've seen a video where they put an s15 sr20det into an s13. so it's definitely possible, just don't know what needs to be done to get it to work.

i fyour talking about the ka24de then i belive it's a direct swap..

s14 = OBD II
s13 = OBD I
Everything is about the same, but you will have to swap some extra parts (motor, dist, ECU, sensors).

Someone correct me if I'm wrong, but I know this is the case with other new to old swaps (e.g., Hondas).

There are differences in sensors and some wiring.

i would say that the "longblock" (valve cover to oil pan) should be the same.....KA motor, right. but most of the bolt-ons (ie intake mfld etc) wouldnt cuz of OBD II like HippoSleek said. i think anything OBD II  related would be intake/sensor/wiring. if just replacing a KA in to a 91-94 you would think its the same..?? thoughts??

Swap the S14 motor, and use all the S13 DOHC electronic stuff (Distr', ECU, etc...)
