Yes, theyre the same sleeves as all b series engines...just 3mm thinner.
84mm vs 81mm

All you can do is get it tuned really well...and hope (or you could sleeve it and be done w/ it)
Just dont be surprised when it happens
this is incorrect, they are the same thickness as all other B series sleeves, just a different siameese design casting for the b20. The casting has a tendency to crack along the seams between the cylinders. Contrary to most "internet forum" knowledge, the b20 ISN'T just a b18 with 84mm cylinders. Also, even if that was the case, you can't overbore the b18b clyinders more than 1 or 1.5mm anyways.

Yes, ls's make good power and are reliable compared to the b20. I think the gsr is the best motor to boost period. it has stronger rods, better flowing head. not ridiculious compression, much much better rod and main bearings...etc
