I searched recent topics, just a quick question. Is the bore size of the CTR pistons the same as a usdm gsr?, in other words.. could i slap ctr slugs in a gsr bottom end?

 

yes, assuming your block is fine and not taperred/doesnt need bored/honed

Yes you can,but your compression ratio would be to high to run pump gas (without retarding the timing excessively).

 

i couldnt run it on 93 gas?

 

You could,but you will have to take out so much timing to keep it from pinging you won't make much power.11.5:1 is a good choice with some aftermarket cams to make good power with 93 octane.

 

so jdm itr pistons should do fine then i assume

 

yer assumption is correct.. 11.59:1 compression when you slap in the jdm itr's.. assuming youre keeping everything else stock..
