Oil Pump Selection?

[slomove]

I am in the process of re-assembling my refreshed ZX1 engine.

The oil pump may still be O.K. but the gears are a bit scuffed and while I am at it I can just as well replace it.

 

Looking up the usual places I find following brands:

 

Kragen:

- AE Clevite $ 280

- Sealed Power $229

- Melling $214

 

Autozone:

- Hi-Tech $172

- Melling $140

 

Summitracing:

- Melling $143

 

NAPA:

- Unknown brand $240

 

So, any reason not to use the Melling pump from the auto store?

 

In another post Gary Slutz mentioned an HP oil pump but I am not sure what that is.

I understand that Quicksilver had a billet pump at one time but maybe not for the ZX1.

BTW, I am going to use ACL Aluglide aluminum-silicone bearings as recommended by the engine builder.

 

 

Thanks,

 

Gert

can't help you with bran decision, but check out www.rockauto.com. They have many brands, and I have found their prices and service to be excellent.

Melling has always been reputable amongst the domestic engine builders.

 

~I've~ not been happy with Sealed Power.

 

Don't know Hi-Tech

I have used melling in the few engines I have built, never had a problem.

Gert - Northern Auto Parts has the Melling M213 oil pump for the ZX1 available for $113.46. I’ve never used them before but might be worth a shot.

PS: I've never seen a HP pump for the ZX1 motor.

Hi Gert,

 

The one I purchased came from a member and he didn't use it, prior to selling his car. He treated me very well on price.

 

It was from CFM # M6600ZX# and was with the Billet gear. Their contact info is: www.c-f-m.com 407-339-9211

 

I wanted the Billet gear pump as I had read of failures at 7,500 RPM + with the others.

 

Folis gave me a heads up on rear main seals leaking, not the seal, but the seal housing gasket. He told me he changed a few seals till he did the gasket correct. I would go over to the Birkin site and pull up his posts or ask him for more info.

I am planning on replacing my stock pump with CFM's SVT oil pump (referenced above). They are, however, on backorder until around the 11th of July. It is a stock Ford pump, only with billet aluminum gears instead of plastic. Supposedly, it is no more durable than a standard pump, but it will take greater revs. The stock pump gears come apart over 7400 rpms. The people there are friendly and helpful, and the parts I have purchased from them so far are 1st rate.

Plastic, what???

 

Obviously the ZX1 oil pump is different from the ZX3 and SVT pumps. The pump that I removed had some pretty good looking ground steel gears. No Plastic whatsoever. And probably no wonder that it is more than 2x the price of the ZX3 pump?

Perhaps that's why the CFM pump is $299 and the billet gear set only is $249; A cheap a$$ Ford pump!
