Oil Pump differences

[d112crzy]

I was just broswing http://www.importperformanceparts.net/ and noticed that the f22a1 from the prelude has a different oil pump than the f22a1/4/6 in our cb7's.

Part #'s from http://www.importperformanceparts.net/
OPH26-HV- Prelude F22A1
OPH20-HV- Accord F22A1/4/6

The F22B1/2 also have the same oil pump as the prelude f22a1.

Shows the same part number(93744) for both

Prelude(No.5)

Accord(No.7)

Anyone know what the physical differences are?

not sure on the differences, but i bought the b1 pump from them, therefore the #26 PN. i'll see if i can find pics

edit: only one i got...prolly wont help much

I have no idea what the difference is. They look the same on the outside. I haven't bothered to take them appart though. Both cars produce similar oil pressures... I've got an accord f22 in my prelude right now, and the gauge is constant between the 2 motors. I'd guess they think there is a sensor or something on the prelude that there isn't on the accord.

I think it's the same 'coz at hondaautomotiveparts.com if you order either one it will highlite the part if you check it on the other, meaning if you click buy on the oil pump for the prelude and then go to the oil pump for the accord it will already be highlightened (on red)

I knew of these differences as well Jose in part #'s, but not physically, never cared or had reason to find out.

[bcjammerx]

so same physically just different number?

You think it has something to do with windage trays? They have different pick ups. Who knows. I guess I'll just get the one for my engine.

[preludeman92]

There's no windage tray on the prelude motor and apparently only on f22a6's too.

[bcjammerx]

so are they the same internally just different part numbers, or does no one yet know?

[preludeman92]

They're the same externally. Internally, they may be different. They function the same though.

[bcjammerx]

ah...and that's the most important difference

On the F22a6 you have an oil cooler built into the oil filter housing base area. You also have a windage tray on this motor that requires a mating F22a6 oil pickup. Those are the differences I know of.

The Prelude F22a1 and All 90-93 Accord F22a1/a4/a6 oil pumps are the same according to Majestic Honda's part #'s. They all retain the same oil pressure relieve valve spring as well. So they should not be different.

TOGA has their own designations, but the OEM part should be the same.

Anyhow, I would stick with OEM when it comes to oil pumps, from personal experience. You just don't chance critical items with aftermarket quality, which is not as high as OEM. Sure you may think that aftermarket should be better/more advanced, but in most cases they are not.
