Im assuming you are coming from a d series?.. If so then ill probably recommend a B18 engine. B16 would be fine too but you'll want some torque to do some hill climbs.

Crossing out the b16, theres the b18c2 and the b18c7. Theres also the jdm b18c which makes a bit more power than the c7. Out of them the cheapest is the b18c2 which features a two stage vtec and is found in the integra vtir. It is a good daily engine but if you want more power go straight to the c7 or jdm b18c from the integra type r.

With any of these conversions youll need the engine package which will include everything to install. Usually these come with eg/dc2 mounts so for ek you will need a set of ek mounts. You can go OEM which are found in the ek4 or em1, or go aftermarket like hasport or hardrace. Along with this you will need the loom from the em1 or ek4.

Other than that, everything should be alright. Hope this helps!
