YOU ARE PURCHASING THE BAFFLE BOX & SURGE PLATE/WINDAGE TRAY & BLOCK OFF PLATE ONLY. ALL OTHER PARTS ARE FOR ILLUSTRATION ONLY.

Oil control panels for FRONT sump 1JZ-2JZ Toyota & some Lexus. This is the SPORTSMAN VERSION which allows the use of the factory oil level sensor, THIS KIT IS TO SUIT THE ROUNDED FRONT SUMP AS DEPICTED IN THE PHOTOS.

The 2JZ engine while being very strong physically has some real problems when it comes to oil control. The sump is a problem,being very shallow & wide both fore & aft with no surge control. The factory panel does nothing to control surge, it's basically just to prevent the crank from whipping up the sump oil into the rotating assembly. This system is the best available for the factory sump. Whilst not being specifically designed for dedicated drag use, when I designed it I took into account high rates of acceleration and deceleration. The windage tray is an important part of the system allowing windage oil to be stripped from the crank and providing a calmer environment for the oil to deaerate and drain back to the sump proper. 

Would Suit :

1JZ / 2JZ ROUNDED FRONT SUMP LEXUS STYLE. This style of sump is used in some later model JZ motors. We are aware that they are present, but not limited to, in JZX110, JZS171, some Toyota Aristo models and some Lexus models. If you are unsure please send us a photo as stated above and we'll be glad to help you pick which is to suit your application 

Other Information:

Prior to shipment we will need photos of your EXACT sump you're are using as between models/series/build dates the sump setups can change. Given there are so many styles of oil pickups between the different JZ sumps (we are aware of 4) this kit fits nearly all of them. One will require slight trimming of the baffle box.
