1JZ-FSE problems

With proper car care, significant problems with the 1JZ-FSE engine installed on it should not arise. However, there are a number of disadvantages of this engine model that can cause difficulties:

1. Ignition coils (may periodically burn out);
2. Injection pump and injectors;
3. Overheated catalysts can create problems and are difficult to remove.
4. If the pressure sensor is faulty, the engine cannot be started.

Tuning to increase power

Tuning a naturally aspirated engine is always a rather dubious question in terms of the result. You can change the camshafts, the throttle, flash the computer, but you will not get a solid increase.

Installing a turbine or compressor on an atmomotor will be much more expensive and less reliable than a swap on a turbocharged version of the 1JZ-GTE.
