Here are power goals, 200@9psi on a JDM D15.

Now, i kinda wanted to shot peen the rods, but its becoming critical that i have a car and i want to know if shot peening D16A6 rods will make a real difference, or will they hold the same at that low psi.

 

You better tune that bitch. 200 on a d is hard.

 

honestly you probably dont, but it would be a good idea just in case.

 

Well, im taking it to the man. This guy is said to be a genius in the southeast, one of the top tuners down here in GA at one of the hotest shops around. So, tuning is not a worry, it will be tuned, and it will be tuned good. So, you think it helps that much, or at that point is it all about the tune?
