Z6 cam gear on Y8 fix timing issue?
okay i got a friend that just built his D16y8 for boost and i was tellign him about the pain in the ass the timing was when i had mine. i know there has been advances in the p2p timing maps over the past few years but i was wonderign if it would be easier/possible to just use and z6 cam gear and timing belt so he won't have to worry about that.
he's shooting for 400hp at whatever amount of boost it takes to get him there lol. |

I have never heard about any timing problems with a hole y8 motor. If you do the z6 cam gear your just asking for it. :3

If you put a Z6 cam gear on a Y8, the motor will be mechanically out of time.
If you do an OBD1 conversion on a Y8, you will not find 12 degrees base timing with the distributor anywhere remotely near center. This is not a problem, stop making something out of nothing over it. P2P maps are minimum allowed timing maps, they are most certainly NOT the timing maps you run when OBD1 converted. Take Z6 mappings for NA, set your ignition timing for 10-12 degrees at 10 psi. This will make a decent basemap to tune from, and the engine will likely want more timing in the lower and midrange RPMs, but don't ---- with it until you get it on a dyno. |

Re: Z6 cam gear on Y8 fix timing issue?
Yeah, I deleted it due to excessive whining. It took me two afternoons and $100 in dyno time to figure out what was going on, and I've never owned a Y8; I was sick of 11 pages of excuses and people who couldn't be spoonfed enough.

Re: Z6 cam gear on Y8 fix timing issue?
Yeah, what he said!

Re: Z6 cam gear on Y8 fix timing issue?
that sucks, there was actually some good info in there. if you read between all the whining

Er, $100 of Steve's money, I meant to say. ;)

Re: Z6 cam gear on Y8 fix timing issue?
Nah man, that was your money... I was just holding it. You earned it! By the way, Y8 with 45000 miles since boosted and 25000 since tuned on dyno is still running incredible. Now, if I could just turn up the boost and lean it out overall due to the new fuel pump install...
And for those that are reading this and still want to know more about the Y8 timing, listen to JD, its a simple matter, do not make this harder than it is. Do what he instructed and stop whining. This matter is now closed! |
Re: Z6 cam gear on Y8 fix timing issue?
Sorry to be one of those that want to be spoonfed...
If it makes you feel better, I can be forkfed. Anyway, I'm looking for information on the y8 head and the timing... A decent source. My last CRX (RIP) had a z6 block/y8 head and was running on a stock (I think, screws are stripped to open it) p28. Ran shitty, boggy as ----. When I bought the car and drove it home, I called the guy and asked if he knew why the car seemed boggy, the dude (young teen car noob) said it ran just fine. I knew the difference between "running" and "running fine," and the car was not running fine. He gave me a chipped p28 with the car (it was turbocharged before he got it) and I used my handy willem to burn a new map to the chip. Popped it in and always had a CEL but it ran MUCH better. That was about a year ago and I forget what I did to the map to make it run better, or what map I used, blah blah. Anyway, my current CRX will also be running a z6 block/y8 head setup. The chipped p28 should still work fine. But it will be boooooooosted. I'd like to get some more info on the y8 timing before I jump into tuning a freshly built setup. Detcan and LC1 won't be sufficient to do a street tune? I hate paying people for ---- I can do myself, and want to avoid the dyno costs until I'm ready to fine tune it. So where's some good y8 timing info? |

I just summed up everything you need to know in this thread.

Re: Z6 cam gear on Y8 fix timing issue?
after posting this i had went and found that thread again to remind myself of what the final outcome was. still good info after all these years :y
