hey guys i have this ge sleeved and o-ringed b20 that is just about 86mm. I have decided to re-sleeve it if i use it at all. Just wanted to double check on here and get your guys opinions. Everyone i have spoken to thinks its pretty much a waste of money and time to try and use it how it is, and i agree. just thought id be sure. 500whp is the goal as well.
thanks

 

I've never heard of someone boring to 86mm. 85mm maximum but not 86mm, however I could be wrong ..

 

86.mm on FI is not a good idea. I would send it in to get resleeved. In the long / short run if you don't resleeve you would be spending more, than if you would have started fresh with a resleeve.

 

86mm NA on a an 84mm is rather common for a B20, but I'd look at the components and parts to use before you decide. It would be a shame to destroy something once, and can't the parts needed to replace.

 

86MM is ok for na but for turbo i sagest no bigger then 85 we can resleeve it for $550.00 just let me know when its on its way

 

OP, there you go, $550 for a resleeve. How much more would you end up spending if you were to build the block and have it take a sh*t on you?
great customer service GE.

 

i have a freind who used to have a 87mm b16 all motor in his drag civic, sleeved and concrete filled.. and i have a friend with 85.5mm b18.. all motor..

 

N/A would be fine, but not for F/I

 

concrete filled? what the heck is that?

 

people do it for crazy high boost cars ive seen or heard of a few supras in the 1500whp range doing it how muxh stronger it makes your block i dont no but it sure as hell prolly keeps **** from moving around in there

 

just like it says... in between sleeves and block is filled with concrete.. its for race car only.. other wise **** wud overheat fast...

 

86mm can be done with boost but headgaskets will own you

 

ok yea pretty much what i expected/kinda wanted to hear. Yeah i Pmed golden eagle last week for a quote so yea, i figure around $650 for a resleeve+oringed after shipping is all said and done? not a bad choice and pretty much my only option unless i want to waste more money. thanks guys

 

DEVCON to be exact... **** that ****. (re) sleeve it

 

I would use a loose piston to wal clearence and run that bitch

 

lol i honestly want to, but i cant hardly afford to buy and assemble everything once. I definitely dont want to do it twice. plus it will be a daily driver and see some long distance trips. reliability is very important

 

why do you want to go 86 when you are only looking for 500whp people make 500whp on 81mm all the time

 

i dont, i purchased the block used and was under the impression it would be fine to use. I get it and its 86mm and still needs a hone lol. if anything i would just be trying to "make do" with what i have. what bore do you guys recommend for when i get it re-sleeved? like 83mm?

 

83 or 84mm

 

i would go with 83 or 84mm personally.

 

dang beat me to it! i was too busy reading the thread! lol =P

 

x3

 

ok word thanks guys. this build would be moving faster if i had money lol, but soon enough ill be sending the block back to GE.

 

Even if you found an idiot, I mean NA guy to buy it for a decent price, you'd still be paying about as much to get a sleeved LS block from GE. In the end I'd choose the resleeving, due to it being a good deal. I'd go with 83-85mm, depending on the goal.
