In case you didnt know, which you dont. I come from an EXTREME MILITARY BACKGROUND. I was out of highschool at 16 and in the recruiters office before I was 17. My father was 24 years in the Air Force and I probably spent mor time on military bases than you have been alive. Dont feed me that **** about the military, my father had to be snuck out of Iran in the middle of the revolution under a blanket in the backseat of a car. you dont see me whining about it. Yeah it sucks that you were in Iraq, but NO ONE put a gun to your head & made you enlist, you did that on your own KNOWING FULL WELL THE REPURCUSSIONS OF YOUR ACTIONS.
Now on to the subject at hand. The internet. For you this service of the forum is free, but for the NICO founders it costs money to host a website and it costs even more for them to have enough space on a server to host the same question 14 billion times....hence the search feature.
Now back to your military comment....the military also teaches you the importance of honesty, honor & integrity. If you had done your research, as NISMO RB25 stated you would not have asked if you should get the clip and how much it would cost. You would research the MANY nissan/RB forums and find the answers...they ARE out there. but I will make it simple, no sarcasm at all
RB26DETT into S13 will run you no less than $10,000 to do it right and worry free.
