Dont hate me...

[ae86ca18det]

people prefer the sr20 because its huge aftermarket support, its an aluminum block, which actually is barely lighter, and comes turbo, so from the factory is already beefed up to withstand turbo applications, the bottom end has more structural support. but in my opinion i dont like the sr due to its head design, the best head design is the ca18, which is identical to the rb motors, cam over valve set up, instead of floating rocker arms , i prefer timing belts not chains, the SR. was actually built to be an ecomony engine for nissan to replace the ca18det which had a much more higher cost to build. so ca18 has my vote any day, but the KA24 PUTS OUT KILLER TORQUE!!!
