Focusing on what's important
Why would anyone do this?
Yes, we agree. At first glance this is a dumb idea. We do not recommend you delete your VVTi. The vast majority vehicles benefit from having functioning VVTi. VVT-i has been proven to work extremely well in a huge variety of scenarios. We LOVE VVT-i. So, why does this exist?
Well, in certain scenarios, someone may want to delete their VVT-i. Here are a some possible examples:
- BIG POWA! DRAG RACING. For head availability, you use the VVT-i heads which are still plentiful. But you've got BIG cams and stiff springs, which always fight with the VVT-i control. You don't need VVT-i doing anything unpredictable. Let's get rid of it to make sure that cam stays locked where it's supposed to be.
- Someone might want a simpler configuration for tuning and wiring purposes. A good example of this would be someone who want's to swap to a new head from an old 2JZ-GE head that runs a distributor. Using this delete would allow a more stright forward swap without having to worry about tuning VVT-i.
- Aesthetics. Someone is building a show car, and want to remove the factory VVT-i Gear for something more pleasing to the eye. This will get that done.
Selenoid Removal
We've included a VVT-i Solenoid Delete that allows for passage of oil. This keeps the first cam journal properly lubricated and eliminates the ugly factory piece.
Some Details
The PHR VVT-i Delete Adjustable Cam Gear is constructed of billet aluminum. The outer gear is hard anodized to reduce wear.
Our locks are constructed of Stainless Steel to for strength and resistance to rust or corrosion.
The Gear features a stainless steel cam seal boss. This allows the cam seal to seal properly while sliding on the boss. which would otherwise wear out if the cam gear was made only from aluminum.
A Locking Cam Gear
Adjustable cam gears are important for dialing in opening and closing events on camshafts as well as lobe centerline. You camshaft was designed to target these specific events and you need an adjustable cam gear to adjust them as close to your specifcations and requirements as possible.
Beyond that, you may be able to find additional horsepower or tweak your power curve to your specific needs by adjusting the valve timing with these gears.
PHR Cam Gears also offer an engine dress aspect that looks amazing in your engine bay and pairs perfectly with PHR's accessory pulley kits.
The Powerhouse Racing Billet Adjustable Locking Cam Gears are the only gears in the world for the 2JZ that offer a way of locking the gear and absolutely eliminating any chance of slip. See our video below. The PHR Gear comes with the 0 position lock which will be the most widely used postion. For those wanting to adjust their cam timing the PHR adjusting kit is available. This kit allows adjustment from 1 degree to 9 degrees positive or negative and assures that your gear CANNOT SLIP FROM ITS ADJUSTED POSTION.
