I'm still a bit of a n00b when it comes to Honda engines so sorry for the dumb question(s). I am currently working with a D15B Vtec engine in my 96 civic ex. I have also just learned that there is a 3 stage vtec for the d15b. I also noticed that the 3 stage vtec have two vtec solenoids, mine only has one, assuming i have sort of a basic vtec on my engine. what are the differences? what on is better? and if I wanted to "Upgrade" (if its even worth it) to a 3 stage how would i go about doing it? Note: i do plan on boosting in the near future. I appreciate all the help and info provided.
