can stock oil pump support 550hp? or do i need toda or prodrive oil pump?
thanks

 

Use a ITR oil pump. Bolts right in and pushes a little more pressure than your GSR pump.

 

i talk to acura. they said ITR and gsr are samething.

 

looks like from your sig that you work at a honda dealership. Do you know for a fact that the type R and GSR pumps are different ? http://www.acuraautomotiveparts.net show the part numbers as the same (9043). Just wondering since I bought a new GSR one and thought is was the same as a type R.

I'd run stock. The gsr and type r are identical.

 

When your talking to Acura, your probably talking to some lazy parts person (my assumption) that does not want to do the research and crossrefrence the parts. Believe me I know. I have lazy parts people at my dealership too. Fact of the matter is that the ITR does flow slightly more pressure because the gear rotors have tighter clearances. My friend and I did a comparison from his LS pump or GSR is your case and the ITR. I could be wrong though. Nobody's perfect, not even Honda techs! hehe. Do some more research and you might find something different. But from what I've seen there is a SLIGHT difference. You will not see a 100psi difference but 5-10psi you will see. This is only what I have seen though. And remember this was a LS pump we changed. I am assuming that the GSR and LS are the same. Like I said earlier I could be wrong. Hope everything goes well and keep me updated.

 

Also, for some reason ITR parts are cheaper than some GSR parts. Weird. I don't know why. Oh well. Call acura and see what happens. Web sites are lazy too.

 

GSR and Type-r use the same oil pump (same part number). dunno where you get that idea from

Jeff-

 

Stock pumps are good to over 1000hp if the motor is built right...

 

do you use stock pump in your car?

 

Yup, brand new oem gsr pumps in all our motors.

 

thanks for all information

 

Type R is cheaper than GS-R, they have the same part number....

the flows the same, I am sure they have the same tightness in clearance

 

I would guess if the part # is the same its not going to be like a cracker jack box, some are type r some are gsr. they would have to be the same right??

 

Also you might want to match up the year with what you have. For example, an obd1 doesnt have the CKT sensor on it, and an obd2 does so that is were the oil pumps differ. I found this out the hard way. I think the obd1 pumps are cheaper for this reason too.

Tony, I coulda swore you guys ran a dry sump...are you guys upgrading to dry sump this year?

 

G-rotors are an excellent, highly compact design.

Also sintered/powder metals get a bad rap.

cool stuff can be found...

the connecting rods on corvettes are all powder metal

 

He still has to run the oil pump as its primary pump. I guess tony will go into detail about this.

but I thought you only run the stock housing and remove the gears?

 

We are running a dual stage dry sump pump, both stages being scavenges, and the oem pump for the actual pump. There are reasons behind this. One being that the oem pump is a better pump design.

 

Hehe once again true for the B series motors and not for the H's mang.-pdang

 

LS and GSR use different pumps. The LS doesn't need the same oil flow as the GSR since it is not designed to rev that high. The GSR and Type R pumps are the same. I have checked their online part requests and they have the same part numbers.

 

So what are you running Peter? I wonder what Lance is running in the HP civic also

 

How exactly does this work?? i'm not sure i understand how the stock pump sucks from the tank??

Good point about difference in years. And I was modest. I said I could be wrong. Thanks for the info because I learned something now.

PS- doing warranty V6 transmissions for Old Man River's Accord doesn't make me a oil pump expert... I know. hehe. Thanks again.
