the best way i learnt about the RB was working on the engine itself, but not by myself to begin with. im lucky enough to have a tuner/mechanic that is willing to teach me when i want to know something, and is always happy to answer my quesions. it is quite easy to think that the spark plug/coilpack is a single unit, as you cant see the spark plug until you take the coilpack off it....
i guess everyone has there own way of looking into things and finding out info, i did some research on the RB while i was waiting for my car to come over from Japan, but the real learning process didnt start to happen until i got the car itself.
i can now pull things apart on my car and know i can put it all together back safely and not have any issues.
it all takes time tho
