I need a Y8 head
 

I am in very bad need of a Y8 head or z6 pistons or rods. I have a Z6 head I can trade or something. Let me know if you thanks

post in the classifieds.

Re: I need a Y8 head
 

good job faggot :8

Re: I need a Y8 head
 

why would you want a y8 head over the Z6 head? :1

Re: I need a Y8 head
 

Fixed that for you...

;D

Just playin.

Re: I need a Y8 head
 

simply because z6 heads sucks. I will pay for shipping and take it off ya hand.

Re: I need a Y8 head
 

lmao

Re: I need a Y8 head
 

get more compression with a Y8 and they are newer, maybe thats why

Re: I need a Y8 head
 

that still doesn't make up for the horrible timing problems with the Y8 head and dizzy. i will never owne another motor wiht a y8 head as longa as i owne a honda. why woudl you want more compression?

Re: I need a Y8 head
 

oh god, more y8 hate. I'd heard all the oil pump stuff, but what's the hate agains the timing problems and dizz? Does the head flow about the same as the z6, aside from the different combustion chamber designs?

Re: I need a Y8 head
 

The D16Y oil pump is the only structural problem with the Y8.

The timing issue doesn't exist. It takes just as much work to set the timing and tune a Y8 as it does a Z6. The problem is people don't understand how to use a timing light, or expect an ignition map off a Z6 or a LS6 Corvette to plug and play with their Y8. ???

Re: I need a Y8 head
 

not everybody wants to have to tune their car on a dyno with a stethescpoe to get the timign right. the p28 maps are already there to use with the z6 head. i had a big enough headache with my old y8 to not want to use one again. guess it's just a personal preferance.

Re: I need a Y8 head
 

The Y8 maps are out there now, you just have to look for them in one of the moderator's bin depositories. :P

Re: I need a Y8 head
 

oh ok, last time i was looking you were pretty much telling everybody to quite askign you and that you were done with it. good to know you shared your research and hard work with the normal people. kinda wish i still had my old car so i could try them out.

Re: I need a Y8 head
 

LOL u think i am serious?? LOL

Re: I need a Y8 head
 

Sorry if you got screwed on that deal, but I for a week there I averaged ten messages per hour from people who kept asking me if they *really* needed timing lights, etc. And, really, it's not terribly hard to understand that you have to synch ignition maps to ignition timing. SOHC_MShue and ElSpool and others have been saying the Y8 doesn't like timing for *years*.

Re: I need a Y8 head
 

kinda of ironic because i believe i tuned my Y8 with crome using a basemap i got from you :P haha

Y8 not liking timing? Nonsense, i ran the afc hack at 8 lbs with no ignition retardation for months :1

Re: I need a Y8 head
 

Go try that with a T3/T04E and shoot for 300. Hell, ---- 300, try breaking 200. Yanking timing on the 10 psi scalar from 12 degrees to 7 degrees made 27 whp on a heat soaked engine.

Re: I need a Y8 head
 

that sucks, my car never ran as good as i thought it could. it ran real good down low but once you got around 8-10 psi it would feel like it was being held back and i knew it was a timing issue because of the maps. me and a group of other y8 owners on pgmfi.org were tryign to figure it out before JD decided to bust it wide open. we were never really able to get it perfect but we had it so it was pretty close.

yeah i did :-[

oh i can imagine all the messages you probly got.

Re: I need a Y8 head
 

If you look at the Y8 combustion chamber matched with the Y8 pistons, you'll see that it has very nice quench areas. The flame front propagates very quickly in this engine. Too much timing on this motor is very easy.

I spun a rod bearing on my Y8 from running to much timing. I took over a year, but that made it more evident as to what was going on. I was only pushing maybe 150whp, but most of the top rod bearings were pretty worn from over advanced ignition timing.

JD seams to have done nice work with the Y8. I'd take his advice like the bible.


Using Vitara's with this head "should" get rid of all that quench, so more timing "should" be possible. JD, what pistons combos have you tried on the dyno with this head?

Re: I need a Y8 head
 

And I got spoonfed a primer on the way down by SOHC_MShue, and ncturbocivic relayed more of the same from El Spool. I was just first to find a D16 guy with dyno money. :1



I've only met one guy who cared to take his D16 to the dyno. Amazingly, it still runs. :1

I have a half dozen B-boys wanting dyno time, but they are mostly flakes or you have to roll them out of bed to play with their car. Ridiculous, really, but that's car ppl.

Re: I need a Y8 head
 

Hahah, just reading the thread title, and I knew JD's timing advice would be inside. What a nice guy.....

Re: I need a Y8 head
 

If I ever meet you, I'm going to teabag you.

Re: I need a Y8 head
 

Does'nt a y8 head give you like 2hp over a z6 head? Wow that would really be worth the $ and 4 hours of labor ::)

Re: I need a Y8 head
 

wow, this guy really knows what's up. We should listen to HIM! :l

Re: I need a Y8 head
 

Sarcasm, n00b, do you see it?

Re: I need a Y8 head
 

lol @ n00b...

Z6 heads flow more cfm @ higher lifts than Y8's. But y8's have other characteristics that make them good in their own right.

Saying that swapping a y8 head for a z6 head only results in 2hp, since the factory hp ratings of these motors reflect such a change, is re-damn-diculous.

However, going from a z6->y8 head(with a different rocker/cam setup ;) ) could give a significant gain in mileage(I've seen 5-6mpg in highway and city) and a "hp" increase due to the mild compression increase... Porting the 4 crappy intake bowls only helps...

Re: I need a Y8 head
 

*yawn*

Re: I need a Y8 head
 

I guess you're right. High 14sec N/A d15 with 45mpg mixed driving w/ o2 enabled is sorta crappy anyway... I know, I've got lots of excuses in there, but I think it's impressive for what it is. Just like the stock bottom turbo'd crx's out there running 12.7's @ 106mph. It's fast for what it is. Everything is relative.

Also, I wanted to mention that less spark advance, with the same burn, leads to more power. People always think this is a bad aspect of the y8 heads, but in actuality, it means the mixture burns faster, and needs less timing advance. This means less force is exerted before tdc, which is good.

Re: I need a Y8 head
 

No, it doesn't mean much of anything.

Burn happens so quickly, and in such a manner, that unless timing is grossly out of wack there is no appreciable pressure built at or before TDC. There is no situation here where ignition timing is varied and burn held constant. All the Y8 head design does is promote initial ------ of burn via quench. As such, your insinuation of Y8 > Z6 is invalid; aside from what timing they both like for a given airmass, they might as well be twins and dress up like each other.

Can you stop turning a silly thread based on misinformation into a pseudo tech debate based on the finer points of nothing? Thanks.

PS - 12.7@106 is a reflection on the suspension, 200-220 whp on a stock engine is nothing to write home about.

Re: I need a Y8 head
 

i have the Y8 head and Z6 pistons/rods.i could use another z6 head. im in Omaha. if you remeber me.
