    honda/acura noob here.

    how does a b20 compare to a b18? is there a big difference? ive heard yes and no from multiple sources so im not sure:confused:

    thanks for all the help

    also... how fast do you think a 98 integra with a b20b with a couple small bolt-ons would run in the 1/4?

    With a B20B it won't be much different then the original LS motor. If you go with a B20Z, you may notice a bit more power...

    its just that b20 blocks aren't build to rev high, so unless you plan on building the bottom, i think (dont quote me) the max a b20 stock can hold is about 7200rpm before the bottom end goes out. I like the b18, whether it the c1 or the c5 both are nice, rev to 8k ish and with a few minor bolt ons will consume your need for speed.

    Until u discover the world of super/turbo chargers :)

    i no the b18 has much stronger cylinder walls due to the smaller bore than the b20 so if u plan on doing anything extreme such as high boost or high compression b18 is a better route..as far as stock performance goes the b20z is slightly better in hp and torque than the ls b18b1 but other than that the b18s outperform the b20s i do belive

    I'm in the same boat. I have a running LS eng/trans that I wanted to put in my 94dr, But found a b20b and a GSr Vtec head and wondered which would be better to go with.

    I don't want to rev past 68-7000 (I'm too old to be rebuilding things all the time), just a 'spirited' little car that I can have fun with and still put the kids in back..

    b20Vtec*>B18c>B20b>B18a/b

    For non-vtec motors more displacement = More power.

    For the original post, not sure what you'd run the 1/4, but you'll feel the difference driving around town and up hills due to the extra 0.2L




    *assuming its built properly
