its all decisional as of right now, i am trying to put together a low 13 sec ls/vtec to go into my ej1. Right now, i am thinking omni power valve trane, eagle h-beam rods, undecided pistons, and probably gonna run the stock cams for about a month. I was thinking about girdeling the bottom end, but I am getting a golden eagle guard. There is so much controversial stuff, thats why I am asking about the pistons, maybe I should go with an aftermarket company.
