The price has gone way up since I bought mine. It's something like $280.00 USD. They are replacement gears.

 

i've got one, they're great

contact Viren (b18bturbo) he can get you one

 

Why did you guys change the stock one? Do they eventually become fault?

 

The factory H22 oil pump gear is brittle, often shattering or easily scorching if you start adding a very light flywheel with a lightweight crank pulley, along with attempting to turn higher RPMs. They are also know to shatter when great amounts of horsepower are added, somewhere above 500HP in most cases.
Unless your removing a lot of weight from the rotating assembly, which negatively affects the harmonics, or shooting for a very high HP number, the gear isn't needed....BUT, it is very good insurance. Yes i've purchased one myself.

 

is it considerably lighter than the stock unit???

how much does it weigh... I was going all motor without any balance shafts they suggest it for high reving 8000-8200rpm...

 

It's not lighter, it's stronger.

 

The factory gears are cast aluminum units while the ProDrives are billet aluminum, not 100% sure of the grade. Weight differences should be slight if not negligible.

 

ProDrive gears are billet steel, not alluminum. The OEM gears are sintered cast steel.

To tell you the truth the ProDrive gears have gotten a fairly bad rap lately.

 

Big whoops, my lisdexia kicked in.....I mean... STEEL

 

well i'd like to know because at 295 US ... i'ts crazy price... almost half of a nice set of rods...

i'm building an all motor-motor and removing balance shafts and somebody told me to replace this gear so .. i wanna know what is reliable and what is not.... for us canadian's that's alot of money .. because we double it...

so how do you tell if they are a bad now or stuff.... CC operations suck or just machining process or they don't fit right etc ????

let me know cause you guys have more exposure at this.

 

There's alot of information here. Some salesguy from ProDrive came in to defend ProDrives honour.

When I bought mine they were selling for $180.00 USD with a 10% discount from ProDrive to Honda-Tech members. I don't think that discount holds anymore and I don't know if anyone knows why they've uped their price to $295.00. The guy I talked to was named John and he's on the board as prodrive-john. Guy liked to talk and he was going on for about half an hour on all the drag events he was dealing with and machining and manufacturing processes for the products they sell. Those are the best guys to find.

 

Just thought i'd add that Melling makes a complete oil pump for the H series. I know for sure that the Melling pumps are the best upgrade you can make as far as air-cooled Volkswagens go since i've used them in the past, but I haven't dealt with them since I started playing with Hondas. For now i'd highly reccomend the ProDrive gear.

 

what are u guys oil pressures when u first crank up your car in the morning my h23 is 82psi on stock pump

 

That would very a good amount between cars depending on the ambient temperature, the type and weight of oil used, and what your idle rpm is first thing in the morning.

 

10w30 idle at 1100rpm
