i have a spare rb25 block that i can take them from, just they arent in that good condition is all, bit of corrosion at the very ends. wont affect how they work, but something less to worry about, as i went through a period where i would get a water leak a week, after the turbo upgrade on the rb25 ..
i was trying to get the rb25 ones from nissan as stated, but they are all gotta come in from japan, so they would rape me with the prices of them.
