why would someone swap a b20 in? is it to handle more boost or nitrous? i have seen a few around.

Torque. They don't handle boost or nitrous as well as other motors because of the thin sidewalls.

yes b20 is a big 4 banger for honda and puts out some decent tq #'s for a honda but still u might as well go with a b18 of some sort.

Not so much. More to do with the weak rod bolts and r/s ratio. Cylinder walls are thin, but are the least of your worries when using completely stock bottom end. All of this can be fixed with aftermarket rods, pistons, bolts, ect, and having the block resleeved.

Lots and Lots of good info on H-T about these. Search

i had a b20 in my da integra and i have it in my ek now. b20+b16 tranny is so fun its got the torque feel of a v8.

My bro has a b20b with the p8r head and its a great motor. The torque is much better than a b16 and I'm sure if he had a b16 tranny on it (currently ls) he could beat swapped b16s civics. Also they are pretty cheap (about $500) if you need a replacement and don't wanna spend a lot of money.

Just make sure you either get a US b20z motor or JDM b20b w/ p8r head. Those tend to be the ones with the most power.

It has more to do with how the walls are constructed, siamese sleeves. It's not simply a bored out B18B block, it's got different sleeves, so although the rod stroke ratio blows ***** for revving to 9000 rpm, the sleeves will give out under boost easier than the LS, GSR, Type-R, assuming you eliminate thousands of other variables.

b20.... ir'd rock it over b18b
IF i was planning on just simple bolt ons and as my daily driver I'd for sure rather rock a b20 with gsr tranny over a b16 & b16 tranny any day of the week....
just IMHO... doesn't really matter unless you r redling your car every single day..

the b16 will more forgiving with more abuse.
