Engine originally came from a front clip. It was in a skyline for a little while running with little issues. It never saw above 14psi when we had it back in the day. I don’t know of it’s history before hand but anything is possible from JDM land. The scoring of the bores is from the rings, engine had a rebuild at some point. The pistons that were in it were +.5mm over. Good times. ---

Don, Bores measured out at 86mm. Pistons were oem. I’m blaming detonation and pieces of turbo. ---

Definately detonation. some of the scoring could be blamed on rings from over expansion but not all of it. Someone at somepoint beat this sucker hard.lol good times.😃 If you look closely most of the scores do not reach the top of the bore, in fact they stop just below the ridge line. Perhaps the pics do not show this detail well enough. The head doesn’t look that bad in person, seriously it doesn’t. There are signs of detonation but that is not severe detonation. I have a cylinder head that we can compare to see what severe detonation looks like 😛 Newman, interesting. Measure twice, order once 😛 However regardless I would have went 87 anyway. Do the pistons you removed look like factory units? ---

> [@newman](#): > > I measured like 10 times. The pistons i pulled are certainly OEM I’m sure you did, I wasn’t doubting that, that was just a small joke based on our conversation the other night. I was also saying that even if you hadn’t I would have gone with 87 regardless. ---

Is 87mm the max bore size you can go to, or is that leaving room for future block life? (another clean up) ---

I brought all the motor parts into work with me today. I am going to degrease them, start glass beading all the bare aluminum parts and sandblast all the parts that are going to get powder coated. The motor is going to look brand new. I would like to glass bead the head, but I really don’t feel like tearing it apart, so i’ll be cleaning that by hand. Everything else will get some attention. ---
