Hey guys, I'm building an ls/vtec right now and have a couple questions. 1) I'm using PR3 pistons from a usdm b16. It will net me 12.2:1 compression. This should be good for 94 octane pump gas if I take out a couple degrees of timing right? I've got crome and my ecu is chipped so I can tune the fuel in to a good mixture but I'm not sure about the timing for na applications. I've also got 460cc injectors so I'm not worried about fuelling. 2) I know that the studs would be better than stock bolts but are the stock bolts good for my application just to run for the summer? I'm going to be upgrading to studs next winter and h beam rods, forged pistons, etc. Just want to know what the bolt are good til. 3) Would the stock cams be ok with this compression for a little while? Its a JDM GSR head and cams. I went with the gsr head because it was a good deal and they have the quench pads which is nice for high comp applications.
