I don't really reply to posts, but this one is interesting and my post is based on personal experience. I recently had a major engine failure on cylinder wall #4, and it was damaged beyond repair (needing 87+mm to "function"). Well, I live in Alaska and there's no Mitsubishi dealers up here. For a brand new block shipped to AK, the cheapest I could find it for was $1961 shipped. Used blocks are impossible to find here and the lower 48 a lot of people are unwilling to ship to AK, and if they do, shipping costs are not cheap either. Well, the option on sleeving the block including the Darton Dry Sleeves, shipping, plus labor (machine shop work on both head and block, plus the sleeves installation) is going to cost me $1493. My builder is a good friend with the machine shop people, the best one in the area, and every machine shop work he needs for builds is through them (more like a contract). I'm in a win-win situation because I basically "regain" the integrity / strength of the block back, and if something happens again (hopefully NOT!) I can just change that one sleeve and not all 4 sleeves, plus I really saved some money. Just my $.02 based on personal experience.

 

So 1493$ for all for sleeves installed and machine work? What's your current power level? How many miles have you been able to put on the motor?

 

probably already been said: sleeving is for aluminum blocks; you add iron sleeves. our blocks are iron. there is nothing to sleeve. that's why the 4g63 is so stout.
P.S. i've sleeved a Honda block. having a dropped sleeve is NOT fun. i can't say i'd ever do it again.

 

Correct, $1493 for all. Power level will be hopefully 500+whp, since it is currently being built. Mileage wise, don't know how many miles I'll be able to put on it, but hopefully a lot.

 

stop putting holes in em then

sleeving a 4g63 is a pointless waste of time , it will fail

 

I got a block for sale. 600 shipped 80k miles. I spun the rod bearing and just put a new short block in. Pm me if your interested
