JZ-Swap Fan Clutch Solution - Tacoma 2.7L Fan Blade on 7M Clutch

Coolingbeginner✓ OP Confirmed

Problem

JZ-swapped MA70 Supras have difficulty sourcing the correct 10-blade fan, and existing fan blades can be off-balance (especially if trimmed), cause vibrations, and risk contacting the radiator or shroud. The OEM 10-blade fans are becoming nonexistent in the aftermarket.

Root Cause

The stock JZ fan blades are too large for the MA70 shroud without modification, are increasingly unavailable, and trimming them to fit causes balance issues and vibration.
