Anybody have any ideas as to the greatest amount of horsepower one can setup on the B18C5 with *stock internals* without having major reliability issues? Who on here can claim the most HP without upgrading pistons/rods/etc?

 

this means stock block? or just stock bottom end......

anyhow with i/h/e the results have been posted around.

 

Stock B18C5 running stock compression.

 

270whp & 170trq with a JRSC on stock internal.

 

i've seen 275/180ish(i think) on 6psi drag kit. stock b18c5
