The JDM DOHC ZC 1.6L is a totally different engine than the D16Z6... The D16Z6 is SOHC with VTEC, comes from USDM 92-95 Civic EX/Si's... The DOHC ZC is DOHC non-VTEC comes in JDM 88-92 CRX/Civic Si's & Integras (forgot which ones)... There is a version of the ZC that is SOHC and VTEC, and is similar to the D16Z6, just with a more agressive cam... If your talking about this one, Id choose that over the D15B VTEC, because its almost the same engine (same agressive cam), with .1 more displacement, so more low end torque than the D15B...
But as for DOHC ZC vs the others, I dont know... Some will argue the DOHC design is better than the SOHC even with VTEC... But it has limited after market support, and is an older engine... I hear that the ones being sold now are the 'bottom of the barrell' stock, which means they are the shitty ones they didnt sell yrs back, and are now running out of the good ones... But this is just what I heard...
I personally went with the D15B VTEC for my swap... Still havnt swapped it yet, but Im sure Ill love it!
As tankard said, probably the best swap for a CRX or EF Civic is the B16A from a JDM CRX/Civic SiR... Its got 160HP stock, and is fast as hell (in the light weight EF chasis)... But they are a tad more expensive than the others spoke of in this thread... And I say best only because of price, ease of install (its relatively easy since both car and engine are pre-OBD), and amount of power... In other words, best bang for the buck...
