Re: oil pumps for d sereis (honda lover)
nice thanx bro. have u ordered stuff from there and how good are the oil pumps? or any of there stuff cuz i also see bearings also. well i got a 99 ex turbo only pusshing 5 psi u think its god if i should get a h.v oil pump?

Y8 pump is barely enough to supply itself at high RPM's!!!
Take a stock pump and make the modifications as shown on the endyn website. With these done, your pump should flow more than enough to supply what you really need.

i dunno man, ive not had any oil starvation or issues thereof for 40k, with abut a year of that up to 8200rpm and the rest of the time 7.5k...
plus the thread starter is not a high-revving bish like us, he is simply boosting a bit.

I hear you, but I on the other hand have had issues, twice now. Maybe your just lucky.

Not enough supply of oil to certain bearings at high rpm's
Honda reduced the oil pump output by 30% after 1995 for reasons unknown. It may or may not affect you, but it is the biggest issued with d16y5, d16y7 and d16y8 engines since they came out

How ever, for the many that HAVE experienced oil issues, there are probably 3-4 times as many who HAVE NOT experienced the same.

Re: oil pumps for d sereis (civic-4-ges)
well these motors arent junk so its a good thing that they arent all oil starved and spinning bearings. i think if that was the case we would have a recall. but this guy is boosting so why take a chance? i just have stock d16y8 no boost some bolt ons. im not buying a hv oil pump. but it was on my list of things to do when going the turbo route.

Re: oil pumps for d sereis (civic-4-ges)
I'm going to have to agree with Builthatch. I haven't had any problems with my stock Y8 pump.

Where do you come up with those numbers?

Oh wait,your not on d-series..Oops!
Ok...design spec from Helms manualforboth D16z6 and d16y8.
Note they are not at the same rpm when teasted, but obvious d16z6 is giving higher peak numbers. Proof is in the print!
Note: Operating temperatures were not noted, but I don't see how Honda would not test oil pump output with the oil at same temperature.
D16z6=45.0 QT. @ 6,000 RPM
D16y8=35.2 QT. @6,800 RPM

i have had 3 d16 vtec engines have oil related bearing failings.
for the turbo engine we built for my friend we went with a toga pump and based on pressure it produces more than stock oil pump. i beleive we saw pressure in the range of 25-80 psi where the stock one was 10-15 psi lower.

Exactly, I have seen those numbers before and have explained that they are absolutely useless because of the fact they are measured at different rpms. You made the assumption that the Z6 is giving higher peak numbers, but you cannot do this. By doing so you are assuming that the flow rates are perfectly linear, you cannot make this assumption. Most flow rates are not perfectly linear.
Without having flow rates at the same rpm this data is completely useless and it is impossible to say that the Z6 pump flows more until you show a FLOW CHART.

It's not a belief it's a FACT. Those numbers are no good. They tell you nothing. The Z6 pump could also be choking up top. If you know anything about mathematics or statistics you know that it is foolish to ASSUME something is linear when it is most likely NOT.
Look at a fuel pump's flow chart, you'll see that as the pressure gets higher the fuel flow increases, but only to a certain point and will eventually fall off. It is NOT linear.
Maybe you should come visit sohchonda.com.

Wrong, by stating that the Z6 peaked higher numbers, you are assuming that the numbers are linear.
Let me give you a couple of examples so you can understand.
This would be a linear flow rate for the Y8 pump.
5000 rpm..........20 qt/min
5500 rpm..........25 qt/min
6000 rpm..........30 qt/min
6500 rpm..........35 qt/min
6800 rpm..........35.2 qt/min
The numbers are most likely not linear and could look like this.
5000 rpm..........35 qt/min
5500 rpm..........45 qt/min
6000 rpm..........50 qt/min
6500 rpm..........45 qt/min
6800 rpm..........35.2 qt/ min
Notice in the second example the peak Y8 numbers are higher than the Z6 numbers? This could be the case, you don't know and I don't know. So by saying that the Z6 peaked higher numbers you have assumed that the flow rates are linear.
