difference between blocks

i currently have a b16 complete sitting in the garage but befor dropping it in i want to get either a gsr or typer block. are there noticible gains with the typer or am i better off getting a gsr since there are more common. oh and is there a difference with the jdm version, or is the difference just in the head.
thanks

what you get depends on what you plan and how much money you have.

google it. theres tons of info.

ok. right now the money isn't a huge issue. i was just wondering if the crank and pistons are different.
thanks

well the type R has a higher CR and a little better flowing head....the price difference is going to be about $1000 from a GSR to an ITR.....personally i would go w/ the GSR and build from there....

thanks but i am not getting the head i already got a head. i just wonder if the blocks have any differences, pistons and crank..
thanks

pistons are higher comp and probably built a little better...idk exactly

ah ok. thanks dude if anyone knows for sure let me know
thanks
