RS Machine Pistons

[bigdare23]

I would drop the flat face pistons since you're going with a gsr head (might put you out of pump gas range). Since you're using oem rods, I wouldn't take that motor to 9500 (and I doubt you would be making power up there anyways). So I would rev it within my power range.

When it comes to valve train, rule of thumb is match brands. If your cams are skunk2 get skunk2 springs and retainers, so since you're planning on running blox cams, you should be fine with their springs and retainers (and that's going to save you some $$$). Everything else seems fine.

As for your original question, I believe those piston in 84mm size and a stock gsr head gives you about 12:1 c/r

I am not trying to get into not running pump gas. i am trying to get the compression to the max of 12:1, but i was thinking that i could use the ls rods and use get them cryo treated and use arp rod bolts.. and i am good to go and rev to at least 9500. I am not saying that, that is what i am going to be revving at, but i am wanting the motor to be able to do that..

what would you suggest in my setup too get to at least 200 to the wheels..
