ok got my y7 coming...more help needed
ok...the y7 is coming and had some questions
internally are they the same...for turbo-ing again? and are the bearings any different that the weak one in the y8's? anyone running boosted Y7s with good experience? thanks jman |
Re:ok got my y7 coming...more help needed
did i post in the wrong spot again?
lol sorry jman |
Re:ok got my y7 coming...more help needed
Who said the y8 has weak bearings? the y7 and y8 bottoms are nearly identicle.
The major problem with y8's are the shitty ass oil pumps that fail and destroy the bottom ends. In fact I think all obd2 d-series pumps are crap. |
Re:ok got my y7 coming...more help needed
I have worked on 2 y7's with both around 100k that had killed bearings. I would like to find out what difference there is in the 88-95 pumps vs the 96+
|
Re:ok got my y7 coming...more help needed
It's because they put that homo crank position sensor down on the oil pump, it fucked everything up...
lol, thats the only difference externally, I havent looked inside both to compare yet. Jeff |
Re:ok got my y7 coming...more help needed
isn't the y7/y8 bottom ends pretty damn close to the z6 (minus that obd2 bullshit of course)?
|
Re:ok got my y7 coming...more help needed
yup
|
Re:ok got my y7 coming...more help needed
next questions.. the unreliability factor that the d16y motors are experiencing; is that what's driving the price down? I mean the dude did get a pretty square deal.
Would it be possible to dump the knock sensor and install a z6 oil pump (running OBD1 of course) and then have a more reliable motor? |
Re:ok got my y7 coming...more help needed
yup youll just have to run OBD 1 or 0 and change the oil pan.
|
Re:ok got my y7 coming...more help needed
so d16yX series engine, z6 oil pump w/ z6 pan and thats it?
obviously obd1 due to the Crank fluctuation sensor. |
Re:ok got my y7 coming...more help needed
you do not have to use the crank sensor at all
and the y7 does have a boss (hole) for the sensor if i want to put it in the y7 block ill simply take it outta my y8 these blocks are identical....the pistons are a little different...thats all spent all day yesterday finding this out ls/vtec owners dont use knock sensors and do just fine jman |
Re:ok got my y7 coming...more help needed
and yes the stock y7-y8 oil pumps suck ass
im upgrading to a high-flow toga pump and acl bearings (they have special journals for more oil any comments?...ill be building my y8 block on the side jman |
Re:ok got my y7 coming...more help needed
if your using an OBD 2 computer you need the sensor.
|
Re:ok got my y7 coming...more help needed
onyx....im not questioning your knowledge but do you know this from hands on experience or from other forums?
i talked to 3 guys from honda and 4 guys that are running the y7 block in a y8 car (head and comp) none said it would matter let me know jman |
Re:ok got my y7 coming...more help needed
I have worked on several OBD 2 cars and my knowledge of OBD 2 systems will kill that "theory" that you don’t need the crank sensor on an OBD 2 car. Hell my ------- sol was OBD 2a and so is another friends sol that I have converted a D16z6 to run OBD 2 ECU's as well as B series ECU's. You need that sensor with any and I mean ANY OBD 2 ecu. Sure I can take a few sensors out and the car will still run but it won’t run correct.
|
Re:ok got my y7 coming...more help needed
ok...is there a spot on the y7 block for the sensor?
yes or no? thanks jman |
Re:ok got my y7 coming...more help needed
I said that yesterday but teg told me it ran fine without the knock sensor ??? someone with a y8 go unplug the knock sensor and tell us how it runs :P
|

Re:ok got my y7 coming...more help needed

Re:ok got my y7 coming...more help needed
see there we go
i talked to 4 guys from honda yesterday and all said i would get codes but no limp mode....arghhhhhh need someone that has taken a y7 block and put it in his or her car under a y8 head and comp jman |
Re:ok got my y7 coming...more help needed

haha jman |
Re:ok got my y7 coming...more help needed
no its a mount on the pump go OBD 1 and its in the oil pump, drop to OBD 1 and use a z6 oil pump and youll be fine

Re:ok got my y7 coming...more help needed
why not just swap the oil pump off of my y8 and use it?
funny...both oil pumps (y7 and y8) have the same model # hmmmmmmm ??? jman |
Re:ok got my y7 coming...more help needed
that will work but then were back to the oil pump being junk
|

Re:ok got my y7 coming...more help needed

jman |
Re:ok got my y7 coming...more help needed
yeah the mount is there and its threaded so you can jsut screw it in
|
Re:ok got my y7 coming...more help needed
whewwwwwwwww
all of this for nuttin! lol thanks man but i did learn alot jman |
Re:ok got my y7 coming...more help needed
as for the oil pumps on the y7-8, toga make a high volume pump and bearings for this motor of mine
anyone use them? lemme know jman |
Re:ok got my y7 coming...more help needed
lol i thought we were talkin about the CFS (Crank Fluctuation Censor) too. :-\
|
Re:ok got my y7 coming...more help needed
well we got it straight now...i can use my knock sensor on my y7 block
any comments on the toga pumps and bearings? jman |
Re:ok got my y7 coming...more help needed
lol i'd just start a new topic for that one ;)
|
Re:ok got my y7 coming...more help needed
just leave the stock bearings in there...just slapping new bearings in it will not be a great idea
|

Me personally I dont like anything obd2 other than the entire harness can come out of the car from the ecu plugs. |
