    B17 pistons in a B18C5?

    this combo works, right? no issues with the ls valve reliefs clearing with the itr cams or anything? compression height is close enough between the two?

    its fine valve train-wise, but the rod-ends are wack.

    b16/ls swap nice
    gsr/itr/ctr swap nice

    why whats the story with the rod ends?

    The reason I was wondering is cause I'm real tempted to do a boosted ITR motor in my new civic. I know a kid looking to get rid of a complete ITR swap but he's got CTR pistons in it so I need different ones anyways. might as well go a little bit lower than stock as long as I'm in there.

    how about P61 B17 slugs? that would put the compression at around 9.8:1, I like that even better than the ~9.3:1-ish it would be with the B18A/Bs. Any such issues with those?

    meaning the clearances in the pistons width-wise for the wrist pin end of the rod are different? so one combo there would be interference and the other there would be too much of a gap?

    which is which? ie- piston or rod could be machined to fit the other?

    anyone know this or if B17 pistons fit in a B18C5?
