SR20DET red top potential HP?????
I’m looking for some information on the SR20DET red top, I’m looking to build one with around 15:1 compression ( if I can get more that would be awesome) with mechanical fuel injection running alcohol but it has to stay within this rule book just curious what people think I could expect in horsepower at the crank? Also wondering if Nissan made a crank from another engine that would fit in this engine without altering it that would have a longer stroke to try and get a little closer to 2.4L without going over? Any links on performance parts would also be appreciated? Thank you.
