so i've searched and searched but i haven't been able to find anything.
I am currently building a crazy setup with a y5 head and i'm looking for a d16 block. A friend of mine has a d16a6 block, but i don't know if it would be better to get this a6 or look for a d16y*

i know that they all nearly identical, but what's the differences between these?

 

The fundamental architecture of the D-series hasn't changed in some 15+ years, there have been small revisions made here and there, but nothing to really give one block a clear advantage over another. From my experience, it seems like the Y variants tend to spin bearings less often than their Z cousin's, but that's just my observation. Personally, I'd go for the newest possible block just for the low-mileage factor.

i have thought about this, however i plan on putting new rings, bearings and seals in whatever block i end up with.

first off, why the Vtec-E head. that is probably the worst one you could use. just go buy a complete Z6. even though i have a turbo y8, the z6 is easier because of the obd1.

lol very true...you wont be going very fast at all, but you can save gas...


i would just say put on a z6 head w/ a y8 headgasket and be done

 

come on guys, ROLLER ROCKERS AND A MORE AGGRESSIVE CAM!

 

You guys have forgotten the JDM D16A, 140hp SOHC VTEC came in (as far as I know) the few EG coupes that came out in Japan and the 92-95 Domanis. That, my friends is the best D series motor imo. Rare but existant.

In my area I personally know of at least 10 people with spun bearings in y8's, and only 1 spun bearing in a z6 (i did it... with nitrous)

 

ditto on the Y8 Bearing issues. Most of the Y8's that end up for sale in my area have a spun bearing in them and around 60k miles or more. Most of the Z6's are still running strong, and they have 150k + on them.

 

ummm damnit I have a y8, just curious if I don't run it to 6k rpm every day like I currently do will it be alright?

hmmm never heard or seen anything bout it....do you have anymore info on it?

 

a6.

 

He means the JDM SOHC ZC VTEC, which are not rated at 140 but more like 130. Identical to the D16Z6 but there are rumors that it comes with a more aggressive cam.

 

from what ive read A6's are supposedly the best cause they have steel or iron (forget which) main caps not aluminum like 92+ D's.

 

complete z6, y8 headgasket, y5 sparkplugs works best i think

 

ZC is dohc non vtec

Wrong, ZC came in two sohc forms, one vtec OBD1 and the other non vtec OBD0. Along with the DOHC ZC version

correct. this is a great block to use because of its strength. i would go with a JDM d15b, an a6 or a z6 in that order. since youre already building a head, the factory HP levels are going to be the same anyway. the JDM d15 has slightly smaller displacement, but has a better R/S ratio and is more suited for high rpms. stay away from any of the Y motors. they have a re-designed oil pump that restricts oil flow by over 35%. THAT is why people with EK+ civics report more spun bearings.

 

right on

I can add to the statistic. My Y8 just spun 2 bearings. That thing was taken care of and it still **** a brick on me. All i had was I/H/E and an AEM cam gear set @ +4

yep. my neighbor is a 40-ish yr old woman with an 98 automatic 4dr LX. she spun a bearing around 85k last year. does that mean that the y-series motors are junk? no, but if you are planning on quickening your engine up, i would avoid them. good oilflow keeps your engine alive.

 

That might be a stretch. Oil pumps from y's are what destroys them, they **** the bed all the time. The way to do it is swap out the y oil pump for say a z6 oil pump and you should be golden.

 

my buddy just hit 320k miles in a d16z6 stock 94 ex coupe. i would either do the z6 or a d16a6 with a d16z6 head(to keep it odb1 less wiring issues)

 

If u are looking to build a motor for n/a why not run the d16b5 it stock is 12:5:1 compression
