Thinking of how to modify your 4AGE and budget is not a concern to you. There are a lot of information around and here is one of a very good information and all the parts that needed to modify a 4AGE to a 240hp Normally-aspirated monster. Normally-aspirated 4AGE variant used in the Toyota Formula Atlantic Series is what we will discuss here. The displacement is still at 1.6L, but they fitted it with a fuel-injection/ignition system by TRD. In full-race trim, you can expect to get 240 beat-you-till-you're-senseless horsepower! At home in a 1,260 lb. race car, 0-60 passes by in 2.8 seconds!
Quick calculations show that this monster of a motor develops 150 hp per liter. To put it into perspective, if the 5.7L Corvette engine was tuned to the same level of the 4A-GE race motor, it would make around 855 hp! And the F/A motor doesn't even have steel cylinder inserts!
