On a LS (not sure if a b20 piston will clear) you can add oil squirters into the oil galleys like the vtec models, you can add ARP bolts, you can have the rotating assembly balanced, add a girdle as Kai said, ect. Golden Eagle Mfg. sells parts for Frank motors. You may want to check out what they have for you. I think as long as its built correctly (parts I said, plus some other random stuff) it can and will be just as reliable as a GSR or B16. Your going to just have to build it right and take good care of it. Just my opinon though.
