I have been hearing and reading that the b20's cylinder sleeves are weaker than any other but with a low compression of say 9.0:1 and boost of say 15 psi max, am I still looking at possibly cracking the sleeves on the b20? I have both a stock b18b and b20b and am wondering which will be be better to boost. It's going into a 93 del Sol S with ultimate goal of low 12 second 1/4. I plan on boosting only, no VTEC for me so my compression should stay low. I am leaning towards the b20 because of the extra torque. It would still be more expensive to stroke the b18 to a 2.0 keeping the sleeves stock than it would to just sleeve the b20. Any input?

if your so worried about cracking a sleeve while boosting you should just save yourself the worry and resleeve one of those bad boys. Turbos and a 12 sec 1/4 mile are serious stuff

 

 

Sell both motors, buy a GSR swap and have the block sleeved for 84mm pistons.
