B20Z 2.0L DOHC non-VTEC 99-01 CR-V 143hp - underpowered
B16A2/3 1.6L USDM DOHC VTEC 93-97 DelSol VTEC/99-00 Civic Si 160hp - good if you want a decent starting platform
B18B1 1.8L USDM DOHC non-VTEC 94-01 Integra RS/LS/GS 140hp - not worth the conversion cost
B16A 1.6L JDM DOHC VTEC 89-91 Civic Si-R I/CRX Si-R, Integra RSi/XSi 160ps - older version of B16A2 & A3 (see above)
B16A 1.6L JDM DOHC VTEC 92-95 Civic Si-R II/ 92-97 CRX DelSol SiR 170ps (same as the engine above but with better output,... as you can see not all B16A's are the same make sure you know where yous comes from)
B16B 1.6L JDM DOHC VTEC 98+ Civic Type R 185ps - great engine ofr a swap if you can find one
ZC (JDM equivalent of D16A1) 1.6 L DOHC 86-89 Integra 86/87 113hp 88/89 118hp - less powerful than a local exi engine.
1.6 SOHC, VTEC D16Y8 1.6L SOHC VTEC 96+ Civic EX 127hp - same engine can be found in local Vti's
B18C1 1.8L USDM DOHC VTEC 94+ Integra GS-R 170hp - another great conversino engine if you can find one
Personally i'd go for a B18C6/7 1.8L JDM DOHC VTEC 96+ Integra Type R 200ps, it's a great engine and is all you'll need right out of the box, alot of tuning potential if you can find one of these engines.
aslo see ifyou can find a K20A 2.0L JDM DOHC i-VTEC '02+ Integra Type R 220ps
or
H22A 2.2L JDM DOHC VTEC 92+ Prelude Type-S, 97+ Prelude SiRS Spec 220ps
