It is nice to hear that some people do like the rb.. I did a complete research before I made my decision on it.. I talked to guys in australia where the skyline is the car of choice for racing like in japan... the truth is you can only go as fast as your pokets can take you.. I wanted a motor that had a bullet proof block because I can always replace the internal with tomei part. If want more power then what the stock engine can handle.. so thanks lostyouth for support...
