I'm looking for but haven't been able to find a Nissan OE / Atsugi turbo auto pump (p/n 15010-07P02 or 15010-07P03) - ASCO and courtesy parts are out. While digging around I stumbled on what might be an alternate, the ITM 057-1084. Has anyone tried this pump?
Rock Auto lists it for the Z31 as follows:
[pre]ITM ENGINE COMPONENTS Part # 0571084
Automatic Trans; Turbo
http://www.rockauto.com/catalog/more…818&cc=1209541
A google search for the same part number shows an ebay listing where every application is "turbo, auto":

yesben13: (2013-10-16 05:20:16)
wondering if anything ever came of this?
shromy: (2013-10-16 17:55:58)
In theory it should be the same pump, Someone would need to buy and open it up to confirm.
jaqattack02: (2014-04-23 13:12:47)
Did anyone ever buy one of these and check it? They are still listed as turbo auto pumps on Rock Auto.
Z_Karma: (2014-05-14 18:50:49)
I just purchased one as a replacement for the one on SS 820, I'll update when it comes in.
Z_Karma: (2014-05-16 20:31:52)
Measurements according to this thread:
http://z31performance.com/showthread…-Auto-Oil-Pump
would indicate that the ITM 057-1084 i got from RockAuto is a turbo 5spd and not a turbo auto.
The outer casting has no identification marks.
Guts:
Inner ring, tooth thickness: .4925
Outer ring, tooth thickness: .4945
Sorry Mario, your turbo auto oil pump is in another castle…
michaelp: (2014-05-16 22:10:18)
I'd just like to point out that the 1984 new model introduction states all turbo models got high-volume oil pumps, and I myself have owned multiple 100% stock turbo manual cars 84-87 which all measured out to match the high volume pump. So its a weird topic.
michaelp: (2014-05-16 22:12:35)
One of these days I want to order the Melling pump and measure it.
Z_Karma: (2014-05-16 23:50:26)
Well i'll measure the one out of the SS motor i'm rebuilding and post the dimensions here it for posterity.
G-E: (2014-05-16 23:52:53)
Is that ITM a new casting or did they reuse a nissan casting?
88sinZ: (2014-05-17 00:58:13)
I'm not going to throw a turd into a pond, but i've seen casting flaws in reliant components to come out with shit quality and false tooling in the casting.

Test yo jank, or just run what you slap on the engine.

Z_Karma: (2014-05-17 04:16:07)
Yeah, I have my misgivings about it after finding its not a Nissan or Atsugi core.
It's an aftermarket casting for sure.
G-E: (2014-05-17 04:36:59)
Well I was asking because an aftermarket part doesn't even have to use the same sized gears/bearings/anything as the original… like that other waterpump that comes with a cast impeller…

This is why I'm curious on the Melling pump. They simply list to use a different pressure bypass spring for auto cars. It could use larger gears than the NA pump, or it may not.

or just slap some washers under the spring and measure with a gauge until desired pressure is attained
G-E: (2014-05-18 06:17:40)
Can someone who has one of those atsugi pumps pull out the gear and compare it to the ordinary pump? specifically the housings?
If the high-flow one uses wider gears, that width has to come from having a thinner front wall of the housing, but I'd like to see any machining differences…
Augustus Maximus: (2014-05-19 16:33:24)
The gearing is much wider…unfortunately they are both in my cars at the moment.
Z_Karma: (2014-06-02 07:00:30)
This ITM pump will be going back to Rockauto.
Comparison photos are to the Atsugi pump out of SS820, original motor.
Inner Gear
Outer Gear
Case of Atsugi has a relief for lubrication under the outer gear
Bypass machining differences. ITM is just milled out. Plungers are both fully seated.
Depth of outer gear relief
Height of inner gear standoff
Depth of pump cavity.
Spring assembly seems same, springs offer similar resistance when compressed.
ITM defects, crossthreaded plug, where bypass relief was machined there is exposed voiding (air pockets) in the case.
It would appear that both pumps housings have the same pump cavity volume, but the ITM has smaller gear surfaces, thereby providing less flow.
G-E: (2014-06-02 07:14:40)
Awesome pics, but if the base depth of the cavity is the same, and the atsugi has a wider gear set, that means there's actually less room behind the gear where the oil squishes out ?
Z_Karma: (2014-06-02 17:55:30)
That makes sense to me. My guess would be that the larger gears and the smaller secondary
cavity would mean that it's able to maintain a higher oil pressure at lower RPMs than the narrower gearset.
And according to Teck@EPR's post, the Atsugi pump measurements
matches what he had for a turbo-auto pump. Interesting....
I know he had claimed to bore them out or something, are there any images of this?
Augustus Maximus: (2014-06-02 18:44:28)
SS pump is not turbo auto, is it? IIRC turbo auto is wider.
Z_Karma: (2014-06-02 18:51:12)
It's a definitely a 5spd with the original motor, but the measurements from it match what Tech@EPR was calling a turbo-auto pump.
Doug: (2014-06-19 04:43:56)
The Sealed Power 224-41959 is a turbo auto pump.

I've been saying this for ages. The new model introduction for the turbo Z31 states *ALL* turbo cars got high volume pumps. I've measured multiple turbo manual pumps to be the same sizes as the "turbo automatic" People then argue "well its probably been changed". Which is BS.
Rick88ss: (2014-10-18 14:04:28)
So what's the verdict? Are all genuine or atsugi later model turbo oil pumps the same Auto and 5 speed?
Rick88ss: (2014-10-18 16:10:11)
Pep boys has melling m110 oil pumps for $141 with the 25% discount (treat25) until October 31. Also free shipping just in case anybody needs one.
Rick88ss: (2014-10-29 04:16:56)
I opened up the Melling M110 pump and measured the gears. Both gears are 15mm thick so it seems that it is a turbo automatic oil pump. I have some pics I took with my Samsung S4 mini.
One thing to note is that the gears have fine metal dust on them. So I would recommend opening up and cleaning any new oil pump you get even if it's not going to be ported.

Awesome info Rick. I just ordered one.
However, it was 164.99 and after the promo code (treat25) it was only 123.74+ free shipping. [archived image: biggrin.png]
At that price, i may have to order another one for the next build.

Pics added 2 posts back. How do they look? It took me awhile trying to figure out how to post em.
Z_Karma: (2014-10-29 18:34:14)
Works for me!
G-E: (2014-10-29 18:53:44)
Nice clean casting…
BTW if anyone is ordering one, order a second and send it to me [archived image: smile.png]

+1 to G-E

Just to add some more photos, i received mine today.
Gear width (inner, outer gear was the same but image was blurry:
Cavity Depth:
Oil pressure adjustment for auto cars, the top spring was in the pump, the lower is what i assume they mean by RED spring, even though it's black.:
Casting was nice and clean with inspection/quality control marks.
The sand that Rick noticed:
Enhance!
Can you zoom in on grid A-3 and extrapolate the perpetrators features from their reflection in the car window across the street…
My guess would be a dried lubricant/preservative or something. Crystals around 0.2mm square, which crushed easily.
The mfg date stamp is march 2003, box says Feb 2008, Taiwan. Either way, it's been on the shelf awhile.
Rick88ss: (2014-11-05 03:03:37)
So you got yours. The particles in your oil pump look a little different than the ones in mine but more noticeable. The particles in my oil pump look more like metallic dust. Either way it's a good idea to take it apart and give it a thorough cleaning and priming. Is it common practice or a good idea to pack it with petroleum jelly or just pour some oil in it and spin it?
Z_Karma: (2014-11-05 17:20:09)
I'm going to pack the gears with assembly lube. I've always followed the idea of turning a freshly built motor over by hand a few times with the plugs out,
just to help circulate the oil into the places where it has drained out during the rebuild.
