They are out of business. Checkout our forged oil pump gears as a replacement. Forged Steel (4340), not sintered like stock and thoroughly measured for accuracy to avoid the problems Circuitworx had in the past.

Another option is TOGA

Sorry, there's nothing special about that website or TOGA gears. TOGA gears are powder metal, similar/same to OE gears. They're no stronger as far as I can tell. I have a few of them here at the shop. They are not high volume either--- relative to stock anyway, they are the same volume and same dimensions in every way. The TOGA housing is it's own housing, but is identical to the Aisin housing that toyota uses short of the Aisin letters cast into the housing. Dimensionally identical...
TOGA gears are made in a plant in Brazil as I recall. I actually called the plant a couple years ago when this whole circuit worx debacle was going down. TODA, with a D, is a japanese company that made gears for a while and I believe they were billet or forged. I never saw a set.
If you're trying to upgrade from the OE gear, TOGA is not an upgrade. May be a sideways move at best. Unless you know how to measure a circuit worx gear set, then you should avoid them. They had massive machining tolerance issues in the last year or two of production. Was evident when mic'd.
Fred had a good suggestion or just stick with OE.... or drysump

Toga is a cheap import and not worth the money...Toda on the other hand is a quality part and I believe that is what MW is selling...
I believe Toga is from China and Toda is Japanese...
