Nice to see another one of us
Well this 1.8 is not stock, so that is part of the problem of its bad fuel mileage I will admit, the other is its untuned, which a AEM wideband is in the future so I can tune the airflow meter and the last reason I have too much airflow thru the front, as my temp gauge reads 160 when cruising down the freeway. Compared to the 1.9, this engine is is a 100 times better, and if I can get the fuel mileage up close to the 1.9, I would be very happy. So lets say I would like to get 30MPG with this engine, and even modified I think it can be done.
The engine makes more power and can actually move the car when you need it too, less vibration and much smoother especially at idle, no more planning ahead to pass someone, and the best part: no more of those famous 1.9 valve seat issues.
Your mods are encouraging for me though that I can improve my mileage. I am currently getting 23.5 MPG
If you want more info on the swap, I have a parts list/how-to on another forum. Basically you will need a parts car to pull it off.
