I have a b16 head right now, and i was trying to figure out the best block to use to produce the most power. comments

 

try a b16 block... what its made for, but you can easily put it on a gsr or just go lsvtec.

 

gsr block and type r
might want to try doing the b20

 

B20 or LS........

 

well what are your plans

turbo I would get gsr block and if you can afford it type r. Matched with the b16 head it will lower compression.

ls/vtec go with something like the ls block or if you want to go big b20

 

i would do a b18 block but make sure you get grs or ls b18b or b18c, b18a do not rev. with b18 block you have potenal for very fast all motor
you can use any b-block you want b16 b18 or b20
