IM LOOKING TO SEE WHAT ENGINE IS BETTER D16Z6 OR D16Y8 AND WANT TO NO THE ENGINE FACS CAN ANYBODY HELP ?

 

think the hp specs are like 127hp on a D16Z6 and 130 on a D16Y8..

And that's like...when the motor's new and such, when you account for wear, it's probably less, as for the tq. lbs, I'm not sure...what other facts are there? They're both single cam engines...they're both vtec...they both requires tons of money dumped into them to be powerful N/A and the best route for either of them is a turbo w/ like 9lbs on stock internals..

I'm not sure what else ur looking for
WORD

 

THANKS FOR THE INFO SO I SEE D16Y8 IS BETTER WHAT COULD I DO TO PUT MORE PWOER IN A D16Y8 LIKE WHAT KIND OF CAM,CAMSHAFT,CLUTCH,INTERNALS,ANYTHING TO MAKE PROPER POWER IM LOOKING FOR

with either of the motors, ur not really going to get a lot of power N/A without dumping a shitload of money into it, if you really wanted to go all motor then you'd have to bore & sleeve the block, all new aftermarket internals, the camshaft and camgear won't do anything for u right now until you get everything setup w/ internals, high comp valves, retainers, etc. - then you're going to have to do real time tuning with it...N/A pure power D series are kinda rare as expletive..

You're better off just turbocharging it, I hear you can make ur own for about 600..though I've never seen it...

There are other things that need to be taken into account, one of them being the Y8's different oil pump which doesn't flow as much volume / hour as the Z6 nor can it sufficiently provide an adequate margin of safety for high RPM operations.

 

He wouldn't know that the Z6 head flows better either.


If I remember correctly, the Z6 only makes 1 or 2 less horsepower than the Y8.

 

Z6 - 125hp
Y8 - 127hp

The Y8's have faulty oil pumps that are prone to fail. I'd get a Z6...the head flows better and they tend to be more reliable. However, the transmissions in the Y8's are better because of the steel shift forks.

 

^^ What he said.... I've gone though 2 z6 trannies, shift forks suck....

 

thanks alot so the z6 tranny is not good and the y8's tranny is good so it all depends on what i want to do thanks alot for your information

 

so i think im going for a z6 what turbo would be good for it

 

will a y8 tranny fit on z6

 

z16 engine y8 tranny . z16 forks do suck, so if you go turbo. y8 tranny or build your tranny with some enforcement. For turbos go to http://www.turboneticsin.com, if that don't work for you. I have plenty more to choose from. I'm about to go turbo, just need to finish my interior first. good luck

 

the z6 tranny doesnt suck, its the drivers that do. if everything else in is good shape and you can half *** drive you wont hurt the shift forks. most people slam then into gear while downshifting, not rev matching, etc, etc, is what makes the z6 shift forks break.

 

that's true too. But I'm not going to teach ppl how to drive, so just expect the worse by offering them the best. My z16 tranny is fine, and it should be fine when I get a turbo. I'll just wait, rebuild if I NEED to. good comment tho.

 

z6 trannies are way better cause they don't have steel shift forks. the steel shifts forks are very thin and bend easy. they twist when they bend and cause wear on the syncro collar and on the syncro itself. one good thing though is that the Honda tranny syncro's can take a hell of a beatingbut the bent fork will wear them fast. the bent fork will also cause the collar not to go all the way into position and the tranny will pop out of gear when you release the clutch. the aluminum forks ussually break cause someone tries to go into first too fast and slams it into gear and breaks the fork. i'd rather have the fork fail all at once and not do any damage to the syncro than to have it wear the syncro over time till it finnally won't go into gear anymore.


and yeah i'd go for the z6 motor. only reason that the y8 puts out more power is cause it has slightly higher compression. the y8 head isn't as good as the z6 and neither is the oil pump. i unfortunatly had a poor machine shop experiance that ruined my z6 block. i now have a y8 block with a z6 head on it. i made sure to port the pump outlet and adjust the regulator but i still haven't hooked up a oil pressure gauge to see what my oil pressure actually is at. i'll be doing that when i put the turbo on.

 

The Y8 is a piece of **** and so is its transmission. Z6 FTW.

The Z6 has 125hp and the Y8 has 127hp.

 

yeah...notice how I inserted the word "like"

 

Why not just do the mini me swap z6 head on y8 block?

 

why would someone take the y8 head off of the y8 block to begin with.


stock for stock, i'll take a d16z6 over a d16y8.

only thing that I don't like about the d16z6 is the dizzy pattern, but it's not like that's a big deal.

I prefer aluminum shift forks myself. But I don't really give a ****, whatevers available for me.

IMO, get whatevers easier to find, easier to put into your car.

 

is the d16z6 and d16y8 better than the d15b vtec? or is it the other way around ?

 

NVM

The y8 has a square combustion chamber, the z6 has a hemi-spherical combustion chamber. (its easier to make more power with the z6 head.....when your boosted)

I agree, however I believe the Y8 manifold flows better?

I believe the D15b is rated at the same output of the d16z6 and accomplishes this through slightly higher compression.

In above link, HMotorsOnline lists the D15B at 130hp.

I'm putting one in my car next wednesday or thursday so I'll let you know what I think of it. If you see my other post, you'll see I don't plan to keep the D15B, just 'borrow' it until my D16Z6 bottom end gets refreshed. Then, I'll either use a D16Z6 or D15B head, depending on which one I figure out to be better. . . hopefully someone can help with the specs.
