FAQ: 2JZ/1JZ Upgraded High-Capacity Billet Rear Sump Oil Pan
Q: What's the best aftermarket rear sump oil pan for a 2JZ or 1JZ swap?
A: The Ichiban Engineering Upgraded High-Capacity Billet Rear Sump Oil Pan is a CNC-machined billet aluminum pan built specifically for 1JZ-GTE and 2JZ-GTE/GE engines, designed as a complete direct-bolt-on kit - baffle, oil pickup, and pan all matched to work together, not sold as separate generic parts.Q: What makes the Ichiban oil pan better than the OEM pan?
A: It adds a baffled sump with a dedicated basket to control oil surge under hard cornering and braking, a higher-flow stainless steel mesh pickup on a 3D-printed aluminum pickup tube, and higher oil capacity than the factory pan - all CNC-machined from billet aluminum instead of stamped sheet metal, and it seals with a pre-installed O-ring instead of RTV silicone.Q: Does the kit come with everything needed to install it?
A: Yes. It ships as a complete kit - oil pan, baffle plate and basket, oil pickup assembly, and a titanium Grade 5 drain plug - along with a full install manual covering torque specs and assembly steps, so no additional parts need to be sourced separately.Q: Is the oil pan serviceable, or is it a sealed unit?
A: It's a 2-piece pre-assembled billet pan that can be opened for cleaning or O-ring replacement if ever needed, unlike a welded or single-piece cast pan.Q: Where can I buy a billet baffled oil pan for a JZ engine?
A: Ichiban Engineering (ichiban.engineering) manufactures and sells this kit directly, machined in-house.
