little background info..
drag turbo kit w/ upgraded bla bla
b18c1 bottom end w/ 9.0:1 pistons and rods

tuned to 12psi for daily driven, friend turned boost to about 18 w/ out adjusting the fuel.. im guessing it blew the headgasket and cracked the sleeve..

first off, can this bottom end be resleeved with the damage? and if so im gonna go w/ an 84mm bore.. please lets hear your opinions on this. thanks

Yes, any company can resleeve that block. Why 84mm ? Why not 81mm?

i talked to a guy named micheal up in CT that does machine work and uses AEBS sleeves and he highly suggested it cause he said its cheap HP i know it would be cheaper just to keep the stock 81mm and only replace 1 piston instead of all 4 and alot of the shops including inlinepro in NOVA all suggested it cause thats what they use on there race cars..

Why not 84mm? Everyone wants more power, right? Displacement is free power and torque...

if the crack is only at the top and doesnt reach all the way to the bottom, it can be resleeved.

Is this going to be a race car? If not, I'd stick with 81mm and avoid spending another grand on a new set of pistons. Besides, 81mm will give you more "meat" in the cylinder walls, so you don't have to repeat this mess all over again.

81mm bores have made well over 500whp. So unless you're chasing Gary G., I'd stick with a street friendly 81mm. The money you save can go towards an SC63.

If by free you mean the cost of new pistons that fit the bore, yeah, it's "free": About $800-$1000 free.

i think he meant that piston prices dont really change between bores, so going with bigger bore will give you more power with the same price tag.

Just about any aluminum block can be saved! It can always be welded and fixed.

the block has already been sent out to aebs.. we are gonna go w/ an 84mm bore and forged pistons agian.. this car is a street driven car occasionaly but mainly track.. it put out 305 whp w/ basic bolts ons and some good tuning w/ the 9.1 pistons that are in it now. im currious to know what it will put out w/ 9.1 84mm 12psi? anyone have an simialar charts to show?

btw the greatest thing is that they shop said its garunteed to about 25 psi and before the bottem end will blow agian it will burn up a valve, so headwork is gonna get done soon also..

and maybe since i was the person who put this car together from scatch my roommate might sell it to me in the spring if he decides to sell it.

25psi only? I believe GE's were rated @ 50psi of boost, or somewhere along that line?

Good luck on the rebuild!

i was quoted about 25-30psi when w/ a 84mm bore.. with a stock 81mm up to 55psi.. im sure if its tuned correctly it will go higher than 25psi but this is only a t4 turbo and it cant make 55psi.. now if it was a full drag car then yes it would be a lot more power..

I usually tell street cars to stick with 81mm because it's good for about 700whp. Most people wont be making that much power on a street car, so why take the chance of scaring up the block and then resleeving all over again?

I mean sure you can go .5 overbore again, if you happen to scar up the block, making your bore now 84.5mm and then maybe go on 85mm, but what after that? Do you really want to run 86mm on a street, turbo car? If it's a race car then sure go ahead run 86mm because if it blows up the team has about 3 other blocks ready to go. However the street guys don't have the luxury of having spare motors sitting around. If you sleeve it at 84mm and something happens two times to the walls then you will

a) take a risk of cracking the sleeves because now the sleeves are pretty thin.
b) Have to shell out a lot of money and wait a long time for custom 86mm pistons if you wanna try runnign 86mm on a boosted block.
c) have to resleeve the block again if you mess up the 86mm

At the end if you stick with 81mm you have a lot more sleeve to play with incase something happens to the block. You could always go 81.5mm then maybe 82mm 83mm and then 84mm. There are piston companies that have shelf pistons for 81.5, 83mm as well as 84mm pistons. This is just me personally thinking and planning for the future.
