2JZ-GE NA-T Build - GTE Water Pump Does Not Fit, Use GE Pump

Coolingintermediate✓ Community Verified

Problem

When building a 2JZ-GE NA-T, using a 2JZ-GTE (twin turbo) water pump seems logical since you're adding turbo components, but the GTE water pump does not physically bolt up to the 2JZ-GE block.

2JZ-GTE water pump bolt pattern does not align with 2JZ-GE blockTT water pump will not physically install on NA motor

Root Cause

The 2JZ-GTE (twin turbo) water pump has a different bolt pattern and mounting configuration than the 2JZ-GE (NA) block. Despite sharing the same engine family, the water pump housings are not interchangeable between GTE and GE variants.
