Need some info from the RB30 Guru's. RB30 pistons in RB25 block? Does it work! Compression good? Anyone done this before and having no issues? Reason i want to do this is because my pistons on my RB25 are cracked and we got loads of R31 skylines here in South Africa so the RB30 pistons are cheap and readily available. Where as the RB25 is a import motor for us and parts/spares are expensive! If you guys could be of assistance that would be legendary! Thanks!
