I must say it certainly was Nissan's Answer to the V-tec, the good thing is the SR20 was a popular engine, and renowned for its reliability, so Nissan made the variable lift and timing version of it so kept the good same engine.
No doubt Honda chops and changes the codes all the time. But the good thing is that all SR20's look a stunning engine, easy to work with and can show a big FU to most daily drives.
