Stock 4AC Dyno Results

[Overdrift]

there still is a little hope. doing more research i have found that toyota made a 3A-S engine which was a 1.5L similar to the 4ac. The 3A-S is said to have a better flowing sohc head and comes from the factory with a twin carb setup.








I can't find any proof but it is said it makes 90hp@crank so prob around 70-80whp stock.


The 3A-S was only available in Japan in the 1986 Tercel SR5.
