ZC or d16z6
ok so heres the problem.. i want to stick with a D series.. for several reasons.. 1) there cheap and easy to work on 2) aftermarket parts r cheap to get 30 when i race someone at the track.. and beat them.. just the look on there face would be enough when i tell them i killed them with a D series motor.. but the thing is.. would i be able to make more power with the ZC or a D 16.. im looking to build this motor over the winter.. i would like to run 15 pounds of boost on a fully built motor.. so im debating is the ZC would be a better canadate for this.. o and also the motors will be bought from Hmotorsonline.. unless theres a cheaper site.. and please feel free to give me you advise on what d series.. and please keep the flaming to a min. on the motor choice.. it is my car.. and if i want to build a d series.. i will

D16Z6 or D15B VTEC, but the ZC has poor aftermarket and replacement parts. The potential for a good efficient build is much better with the D15B and D16Z6, and that's really what it comes down to.

D15B JDM motor doesn't have bottom end aftermarket parts.
ZC bottom = Z6 bottom.
There are ONLY 2 parts for a Z6 that you can't get on a ZC...easily.
1. Aftermarket intake manifold.
2. Cam gears. There is a set made by JG...and hard to get a hold of.

40 HP, or 400 Hp? You can get 40 more horses out a stock internal D series all day.

Re: ZC or d16z6 (stock_honda_coupe)
i've got a z6 head and i'm thinking about doing a mini-me swap on my b7 soon for some cheap kick.
is the d15b7 block a good candidate for a rebuild with the z6 head for raised c/r or is the z6 block just better?
and whats a good psi range for the best power for minimal daily driving?

DD is a must.. thats why 400 HP seems abit to much.. altho ive seen it on some mustangs idk.. maybe i should just built a b series.. but everyone seems to have them and i wanna do something different.. thats why i was thinking D anyways thanks for you help.. guess everyone will have to wait and see my build post to see the motor i choose thanks for your help in my decion. altho i can safly say D series is out completly..

I think the Z6 will be a great candidate for your SOHC build regardless. USDM engine, lots of support, plenty of parts just for that engine.

the best way is to get a dx block, with a vtec head,
change the internal to a zc, an go from there,
dx block= torque
vtec head= high end
= one mean D, lolz
yeah im fan of a D too
dont hate

This topic makes my head hurt.
First of all you guys need to think about this:
There are literally 4 or more different ZC engines - DOHC brown top; DOHC black top; SOHC non-VTEC; SOHC VTEC, some carb'd old-*** ones, etc. etc.
So are you talking about a DOHC ZC? If so don't bother building it. The aftermarket is limited for them, and they seem to have more head gasket issues than SOHC engines when it comes to boost.
IMO the ideal SOHC build for boost would be a 1988-1989 D16A6 from the CRX Si or 1989 Civic Si HB because those engines have cast iron main caps and are the strongest SOHC blocks around. Either keep the non-VTEC head and have a GOOD port and polish job done to it, toss in some 9.5:1CR slugs (this is actually a touch higher than the stock 9.2:1CR) with some 86-89 Integra D16A1 rods and you'd be golden.
A SOHC VTEC engine such as a D16Z6 or the SOHC VTEC ZC would be nice too.

Well there are a few problems with your suggestion.
1. The 92-95 DX block is a 1.5L block, which means it will have LESS torque
2. You can't stuff ZC internals into a 1.5L block unless you want the pistons to stick up out of the cylinders at TDC
3. If for some odd reason you're talking about the 96-00 DX block that is 1.6L those blocks suck compared to the older ones. They are known for mysterious rod knocking issues
4. The VTEC head alone doesn't really allow or make for higher rpm than a non-VTEC head. Stock for stock the VTEC head has a slightly higher redline, but if built properly you can rev a good old non-VTEC D head as high as any VTEC head. The 88-91 D16A6 non-VTEC head is well known for it's portability and it also has more cam choices than any other D head
