  • 12. What do engine tuners think of it? Tuners love the SR20, it is a cost effective platform to modify until your power goals are set above 400 PS. Check out our SR20DET tuning guide to read an in-depth guide on how to extract more power out of your SR.
  • 13. Does it have “cool” factor? With it being an engine primarily only available in Japan, SR20DET’s are considered a cool platform. While Japan, Europe and Australia were offered the SR20 from the factory over in the United States and Canada no 240sx’s were offered this potent turbo charged engine.
  • 14. How does it sound? With the right exhaust manifold (GReddy) and straight through system SR20DET’s can sound cool but it’s still a four pot, so.. not so great in the sound department.
  • 15. Are replacement parts hard to source? Standard and upgraded parts are still readily available for this engine throughout the world. There is a vast SR20DET aftermarket offering so many upgrade options that owners are really spoiled for choice. Check out our friends at Enjuku Racing to see what’s in offer in the United States.

So now you’ve read the SR20DET specs and understand why this engine kicks ass why not see how it fares when pitched in a head to head battle against the RB20DET?
