Differences between D16Z6 and D16Y8?

RosSi · 11-19-2002, 08:26 AM

Like the title says, can someone run down the major differences between these two motors?

Spade · 11-19-2002, 08:27 AM

OBDI and OBDII
Headgasket.
Intake manifold.
Chamber design.
Cam.

brcivic411 · 11-19-2002, 08:50 AM

hey spade, anyway we could drill down even more.. like:

Quote:

OBDI and OBDII - requires 2nd O2 sensor, etc...
Headgasket. different material? thicker?
Intake manifold. y8 has a larger design, etc...
Chamber design.
Cam.

Spade · 11-19-2002, 09:04 AM

Yup.

Y8 has thinnest D series head gasket.
OBDII..different distributor Second O2 sensor, Knock sensor, all the pain in the *** crap you don't want to deal with when attempting to tune an engine.
Y8 larger runners that are slightly shorter.
Chamber: smaller and more angular for better burn.
Cam: Slightly longer duration. 1-2 degrees.

The Z6 has the better bottom end while the Y8 has the better up top. Honda made that Z6 block stronger and the Z6 has the wonderful and tunable P28 ECU. The Y8 has the better tranny. The gears are closer on the Y8. That's all that I can think of right now. I'm sure there's a lot more, and I'm sure the gurus of H-T know them.

haloseven · 11-19-2002, 11:30 AM

so is there an advantage to swapping in a y8 tranny over my stock Z6?...thanks...

NOt worth it. Get a SRR final drive kit.

SRT-WHORE · 11-19-2002, 11:39 AM

I agree. The tranny is better, but not that much better. I don't have the tranny because I swapped trannies. I have it because it came with the engine and car. The SRR would probably be a better choice.

X2BOARD · 11-19-2002, 12:06 PM

How exactly did they make the Z6 block stronger ?

Rods are beefier basically.

As far as up top, I think the z6 doesn't fare so well in terms of quench zones and it handles combustion gases less efficently than the Y8.

SRT-WHORE · 11-19-2002, 12:26 PM

Well said!

brcivic411 · 11-19-2002, 12:29 PM

you guys amaze me

Spade · 11-19-2002, 12:31 PM

Don't forget you could just get LS rods if you are worried about your Y8 having weak rods.

SRT-WHORE · 11-19-2002, 12:36 PM

Of course you could, but that would be modifying it. The question was what is the difference between the z6 and y8. It sounds like stock z6 vs stock y8. We all could come up with ways that the two could be improved but that isn't the discussion.

Good stuff. Thanks guys.

monsta · 11-19-2002, 08:44 PM

Spade, the Y8 trans is the beter trans, and if you are going to auto-x I would reccomend the Y8 trans over the Z6 Trans anyday, teh Z6 Trans has Aluminum shifter forks, and the Y8 is steel, the Z6 has the tendoncy to bend when used hard, even break....

All i could see is both engines are terrible in producing large amounts of horsepower

. I know this because i have the d16z6.

This I didn't know, at least not the whole story of it.

The SRR final drive kit, more preferred over the Vti LSD equipped transmission or just a greater addition on to the Vti transmission?

function83 · 11-20-2002, 02:27 AM

seems like you guys got every difference.

The head is not efficent from factory... a good PnP job will fix that... these motors have been taken to the 400whp mark.

VTC_CiViC · 11-21-2002, 09:10 AM

As I'm sure Mr. Bone will state, the S40 (I think thats the 5G EX) and K4F trannies use the same ratio's, but the 6G trannys are physically stronger internally.
