Hi 1. I have swapped in a 1uzfe v8 into my mitsubishi van. At the moment it is not performing at 100%, I feel some type of hesitation when trying do fast accelerations. How much can a faulty Airflow meter affect the engine's perfomance and what octane fuel can you suggest to be best? I run a 5 bar fuel pump, is that sufficient to sustain the enigne?Can I also get 0-100 km/h times for a stock 1uz. 2. I would like to achieve 300 to 350 rwhp without any forced induction or changing of the bottom end while still keeping the car reliable, any ideas? 3. If I did have to go the Forced Induction way, which options would be best for always giving me power in any situation. Low end to High end. Thanks BTW for your reply in advance.
