Hi everyone, I'm new to the forums, but have owned an 09 for a couple years. I would like to build my own engine and would like some recommendations regarding components. My build will not exceed 1000whp, my target is actually 900whp. I'm also looking for a tear down / torque spec manual. Nissan for that? I am capable of buying direct from both JE and Manley, so I'm looking for any reasons why It would be recommended to buy from ams or such shops over going direct. Any information would be very helpful. Thanks.
