can somebody tell me what the maximum bore size you can use for an all motor application on a b series motor if its sleeved...?????????

i know golden eagle will do a special sleeve for all motor only up to 91mm, but i dont kno if they were only speaking specifically for a prelude motor...

I read somewhere about 94mm. But dont quote me on it, it could have just been 91mm.

wow 94mm?

thanks for the input.. anyone else?

87mm on most aftermarket sleeves. 84.5mm with a Dart block, and about 81.5mm on stock sleeves. Most of the time 85mm is as big as you really want to go with a street motor, certain companies have had good amounts of success with 86mm motors. Most of the time anything larger than 85 is reserved specifically for race motors that won't see a lot of use before being torn down and rebuilt.

thanks.. that sounds more like it.. i didnt think 91mm in a b series block would really be a possibility.. a h-series. yeah since its 87mm stock... so an extra 4mm isnt that bad.. but 10mm...wow...

ya i heard Max bore for all motor is 85mm... but personally i would go 84mm, that way you have room to bore it again if something goes wrong.
