Let me make sure I'm getting this right, the .80 thousands comes off the hump in the center of the piston leaving a small flat spot? Would you happen to have any pictures of a piston that has had this work done to it?

Is there any differences between the NXS crankshaft compared to the 6NZ crankshaft? I know the stroke is longer on the NXS crankshaft but is that it?

LOL...I’m not gonna to try that. I really was wondering if the length of the NXS crankshaft was shorter than the 6NZ crankshaft. Other than that everything is coming together nicely. Here’s a couple of pics of the block and crankshaft after getting everything back from the machine shop and a shot of the pistons after having the bowls cut to lower the compression. I also had them coated.

If you are still planning on using the liners from your 6nz kits i would highly suggest you check the piston to wall clearance and your piston ring end gap of the one piece steel nxs pistons in them....the one piece steel pistons are gonna require more clearance and probably gonna have to hone the liners to acheive it and the ring end gaps they need.
