Well for now ( ;0) ) Im going to go with an N/A Application. I have the gsr bare block here, I get my crank in a few weeks since this crank was a little damaged and brand new rod bearings. I am still going to replace all the main, thrust bearings and other necessary parts. Now I have changed my mind on the CTR pistons because supposedly it will put my compression over 11.5 and I will have pinging noises and have to retard my timing. Now, if I go with the JDM ITR Pistons, I will have around 11:1 CR and I should be fine with the 93 octane that we have here. Other than that, Skunk Intake manifold, ecu mapping, cams, skunk valve train, 65 mm throttle body, and a few other things going on in the head. Just strengthening the bottom end a bit so I wont hve to worry about locking it up later. Any opinions?
