Sleeve or not to sleeve

[X22098]

i have a b20 block and i dont know weather to sleeve it. I was planning on getting new rods and going with a 84.50 mm piston (wiesco) also putting a 75 shot of nitrous into it. Is this going to be enough or is the sleeving of the block ness?

for that low of a dose..dont waste the money..but if you are already tearign the block apart and plan to go bigger in the future..why not do it now...because you'll jsut have to tear everything out again

yea i have to take the block apart and replace the rings i burned up 2 of them.

Yeah save the money for something else like tuning or cams. With that shot you would be ok with a block guard. You mite want to look into a V-tec head also.
