What Are the Common Issues and Known Problems?

The most common Supra MK4 issues include CT12A ceramic turbo failures (requiring metal wheel turbo upgrades), weak A340E automatic transmissions unsuitable for high power, insufficient stock fuel pumps above 400 hp (needing Walbro 255 LPH upgrades), dashboard cracking on all models, and hatch glass stress cracking around the third brake light. Most problems have established aftermarket solutions including turbo upgrades (GT3076R, GT3582R), manual transmission swaps, dual fuel pump setups, and reinforcement kits.

Turbo Failure (CT12A Ceramic Turbos)
- Ceramic wheel turbos prone to failure
- Solution: Upgrade to metal wheel turbos (GT3076R, GT3582R)
Automatic Transmission Weakness
- A340E not suitable for high power
- Solution: Manual swap or build transmission
Fuel Pump Issues
- Stock pump insufficient for >400 hp
- Solution: Walbro 255 LPH or dual pump setup
Dashboard Cracking
- Common on all A80 Supras
- Solution: Dashboard cover or replacement
Hatch Glass Cracking
- Stress cracks around third brake light
- Solution: Reinforcement kit before cracking occurs
