ls/vtec swap????
i have a gsr head already but i need better pistons??? spoon sports type r pistons or jdm civic type r pistons??? if anyone has either these pistons or a different kind let me know how they work.
your gonna have some crazy *** compression with the civic R pistons...probably around 12:1 or more.
