Oil Pumps

[dumbo]

I just finished my remote oil head, and bigger cooler, doing the na-t.

I know the gte oil pump flows more gpm, but the gte also has piston squirters and a stock cooler.

so my question is will my ge pump flow enough with my new setup to keep the oil pressure high enough?? and does the gte pump fit into ge, like can i just replace with no mod. i'm pulling my pan off to weld a bung in so it wont a be a big deal to swapp.

Oil pump was replaced about 10k kms ago when rebuilt. here some pics of the remote head, thermostat, and cooler.

Heres a few pics of the setup, tell me what you think. thanks guys.

well first off im not gonna lie, im no expert and i don't know if it will work out or not but lookin at the tsrm and the epc the oil pump for the two engines are the same, which to me says the only difference between the systems is the oil jets, since the systems are the same except for the oil running through the turbo and the oil cooler it may be that he oil jets are just to keep the pressure up so that the oil flows smoothly through all the excess piping in which case my guess would be that you probably do need them, take a look for urself http://cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=LU&P=1. this one shows the same pump for both engines http://cygnusx1.net/Supra/Library/EPC/291420/engine.aspx

The GTE pump is geared for higher flow...for the reasons the OP stated. Plus it has to feed the turbo. I would use a GTE pump for this motor...it should fit. I would shim the pump relief valve ~5mm for the extra pressure/output.

The oil cooler circuit is set-up to provide full flow to the motor (a good thing) and it should help to keep oil pressure up where it needs to be.

If you don't know find out for sure BEFORE POSTING..

The GTE pump gears are indeed taller to feed the extra volume of the GTE accessories.

it may be that he oil jets are just to keep the pressure up so that the oil flows smoothly through all the excess piping

How would a controlled leak keep up pressure? It lowers pressure. Just like opening any valve would.

I chose to ignore the ignorance and stupidity in the post Nick

ok as i appreciate the advice, i dont wanna sound like i'm knockin either of you.

hacki sack kid, the oil jets would further lower my oil psi, since more flow would be needed. but thank you for stating that the pump themself is the same. that makes this easier, maybe.

jdub, so the gte pump is geared for higher flow, is it the gearing in the pump?? wouldn't that make the pumps different?? what drives the pump, is it there???:aigo: now you say "The oil cooler circuit is set-up to provide full flow to the motor (a good thing) and it should help to keep oil pressure up where it needs to be."--that is stock right? mine is designed full flow to engine, then when warm to to cooler, well its close but nevermind that.

i haven't be able to find anything thing as far as part numbers online, dont wanna waste my $$ on a new pump if its the same pump, but the drive/driven(however it is driven) is what makes the pump flow more.

ps, i'm not worried about the turbo oil, it dont flow much, but my cooler is(i think)

Dumbo: The GTE pump has a longer body and internal gears so moves more volume per revolution than the GE pump.

I believe the GE pump in NLA so they just use the GTE number for both.

The pumps are physically interchangeable consider the GTE pump a Hi Volume pump when used in a GE.

wow how long did i take to type that, ij keep it coming

About 1.5 minutes

ok thank you, so what do you think, should i use the gte pump, got no squirter, but the full flow oil cooler... in the pics. is the ge pump enough to keep pressure up, or should i get the gte pump.. these are i belive

That's the way I read the 1st post

The pumps are different....that's really all you need to know.
I would bite the bullet and get the GTE pump from the dealer...the online sources are infamous for sending a GE pump. It's happened more than once

If you shim the relief valve like I said, you'll get even better flow.

Your cooler circuit should be fed from the NA stud (pump output) on the block. That way, you have lower temp oil to cool the bearings and the turbo. It keeps the oil at the correct ops temp viscosity as well.

what does NLA stand for?

 

[IJ.]

I used to run the GTE pump back when my car was NA/t, more volume is a good thing as long as you remember to add 1 Qt to the pan.

NLA = No Longer Available

yup it is, check the pics i was kinda proud of the setup, but no input on it yet, thats ok the pump is my real question:icon_bigg

ohh i see, i'll bite the bullet and phone the dealer tommorw:cry: so since i have a cooler and turbo would i need more than a extra quart, or would i not need it if it was a stock na with a gte pump

 

[jdub]

An extra quart is all you'll need...that goes for a stock NA too

You do it to make sure the pump pick-up is never uncovered during lateral or deceleration.

ok, i'm gonna phone the dealer in the morning, scared of the price, and availbilty. and i will run the extra (litre:naughty:, damn close neways) but i hope it dont go over the turbo drain bung that i gotta weld in my pan

 

[dumbo]

ohh a little advice on shimming, i know once i see it it wont be hard, but you say compress the spring 5mm right? do you know what that bring max psi too?

If the bung is near the top lip, no way the oil level will get near it.

I get about 50-60 psi at 4000 RPM warm.
