hey guys,
just a quick question, if i install an oil cooler kit on my em1, do you need a larger oil pump to keep oil pressure up in the engine, im just worried as there are more hoses and such and the oil cooler itself you might loose some oil pressure in the engine =S
thanks,
steve

you cant get larger oil pumps.

yes, there are more hoses, and yes, it will drop pressure, and yes it is important to monitor this change when you install your system.

if it drops too much, then you might need to rethink the parts you use, quality and quantity wise...

if you have used quality parts and it still drops too much, you can "shim" the oil pump to provide higher pressure...

IMO oil pressure should be around 20psi at idle, going up to 70psi by 2500ish then 75-85psi over 3500rpm to redline

on a b16 so long as you don't use a big oil cooler it will be fine.
If you need to you can increase the oil pressure, there is a DIY that you can show you what to do

thanks guys, i just didnt want to cause any damage by installing one and then not having adequate engine oil pressure, thanks for shedding some light on this =]
cheers,

You should be ok.... Yes depends on how big the oil cooler system.

I would like to say " she'll be right"...

90% chance it wouldnt drop your pressure that much if its a half decent setup. If you drop too much then just do the washer trick or get the k series oil filter (learnt from tinkerbell)

You don't really need an oil cooler on a street car if all you were doing was normal sprited driving and the 1/4 mile at WSID. Unless your car goes to Wakie often and you do over 10 laps at a time, you don't really need the oil cooler.

100% agree to the above....

However I wouldnt push it over about 4-5 continuous hard laps in mid summer

^^^ agree.... been mointoring oil temps lately...sometimes i hit 100 degree in traffic.

hmmm, maybe divide you 10 by 2 and you'd be closer... especially on a hot day...

measured from sump? take off plate?

i was hitting 125'C on the freeway without oil cooler at 110km/h prior to fitting an oil cooler...

(but that was without the block heat exchanger - like most VTEC engines have)

125ºC on the freeway? Stock B series don't hit that high. I remember they hit 115ºC or so in that summer torture test at Tsukuba.

Yeah, also depends on the engine. An engine running close to 13:1 would put out more heat than a stock one running at 10-11:1 full throttle.

i am refering to a stock engine.

it would be suicide to run a built 13:1 engine hard on the track without an oil cooler... even on a cold day.

Nah, I'm not saying that you are lying. You did mention that you didn't have the block heat exchanger on.

ok, cool.

i was just providing an example of a driving temperature extreme without any form of oil cooling.

(measured at the sump.)

its more to do with the revs.. on hwy driving on an ITR ratio box you will be traveling about 4k rpm constantly for 110..


correct me if im wrong
Only the ITR had the heat exchange and some older b18c2's (dont think AUS got them)... Most b16s and b18s have no OEM exchanger

I remember reading the DC2R hitting 140degrees in the enduro... 115 is rather low

B16A2's civic & delsol 'do' have water/oil heat exchanger.

Not sure about B18C2's? I would have thought they would have them too?

k series oil filter is the same as b series.
so what's the go?

not sure which dc5 filter they are talkin about.. might not be talkin about oem here... there is like a million post about using k series filters on b series to increase pressure as they are smaller..

mine was measure off the head. I know its not the best place.

some b series motor don't have the water to oil exchange.

yes also the rev at 110 factor in the oil temps.

meh, i can't go into those sites at work.
lol.
but yeah, OEM, k series is the same as b series.

so has Honda changed spec of the older style (B & D) filter to the newer style one (K series)?

see how the Ryco catalogue states Z79A for older style (B & D) and Z547 for newer style (K series)

Z79A (76H x 82D):

Have you seen this first hand.. .

from the post : -only older model b18c had them and all ITRs.

Trust oil cooler kit was never made for the dc2r and ek9. It was only for dc2 and ek4. I was under the impression that this is b/c they had no facotry cooler.
Even on the product specs it stats the cooler is only for cars without a factory o/c... so not all b series got them

the JDM first gen B16A integra had them,

but my 98+ DC2 did not have one :(

looks like this DC2 guy has one though:

Also Hamp offers smaller filters to increase pressure.

Max-Hondapower sells these. I use them on my ITR and they work great! :thumbsup:

Thats cool. But I am saying B16A2 aussie, 'do' have a heat exchanger, I saw it 1st hand, yesterday in fact. ;)

what's the heat exchanger that i'm supose to be looking at? i'm abit of a noob on this one.

P.S my car hit 110 degrees waiting in an underground carpark for 20mins, i was kinda shocked at the temp

sorry, it is here:

limbo - 110 degrees for what?

oil or water?

water can hit 110 if the thermofans take too long to come on,

it would be unusual for your oil to heat up without actually driving :confused:

tinkerbell

see how the oil filter attaches to it - the oil flows around the inside of that circular thing, and in another chamber inside the circular thing, coolant circulates...

this way, under hard driving - the coolant (with a big "air to liquid" cooling radiator) can absorb the heat from the oil, via the "liquid to liquid" heat exhanger...

DLO01

Thats interesting if at or near idle. If you have the exchanger, oil temps should come down simular to your water temps.

See this photo:

Disregard the blue adaptor plate, that is my plate which runs to my cooler and remote filter. This is where the Oil filter usually sits.

See that metal pipe comming up at an angle? and the rubber pipe that extends from the metal pipe? This is one of the water lines. The other one you cannot see. Water is passed through the filter mount to cool the oil.

where is the temp sensor located?
