JDM H23 HEAD ?
i dont know if the blue top will bolt on but. Even if it dose bolt up you wont be able to rev any higher then what your h23s redline is right now because. In your h23 you have 50mm main bearings. In the JDM h23 vtec the main bearings are 55mm giving you that extra 1k rpm redline. So if you want to have vtec. Buy a h22 or buy a h23 vtec.
