would 01-03 gx pistons drop in d17a2 with good p2v clearance

zeal calculator is giving me a static comp of 11.87.1 and a effective comp of 11.71.1 , and a piston to deck height of , 0.031 but not sure if this is below or above cylinder i think below not sure please help

 

Someone here used GX pistons on their NA build, I'm pretty sure they're a straight swap, but hunt down the build thread and you could ask that person directly.

 

Stock cam it shouldn't be a issue... google "pms pistons" little to no valve reliefs.
These pistons are also kinda hard to get
13010-PMS-A00 std size 6 available
13020-PMS-A00 .25 os 5 available
13030-PMS-A00 .50 os none available

Take this with a grain of salt: I also remember a N/A build being done with the gx pistons that resulted in higher compression. I would imagine it is totally possible with no modification.

 

I don't believe anyone has actually used gx pistons in a NA build yet. Jonathan2006 and Bomerman both talked about using the pistons but Bomerman backed out and Jonathan2006 hasn't sourced them yet for his build.
