I was wondering which one swaped stock into our cars would run faster? b16= horsepower : b20 = torque???
I’m thinking the b20?
If both had a either a jdm y1 or ys1 transmission, the b20 would probably be a little faster(as long as you’re not talking about the USDM B20B).
A stock B20 vs. Stock B16. I say probably a B16. The B20 would have you off the line though.
I say, all else beeing equal (car and its weight, tranny, driver) the B20Z or JDM B20B equipped car would definitely win.
Example:
92 civic Cx stripped interior
2nd gen B16A
CTR Tranny LSD of course
Toda unltra light flywheel
Mugen 3-puck clutch
Tanabe header
RsR N1 cat back
test pipe
HKS powerflow
Z.Speed cam gears
Mugen ECU
15" pirelli
dyno:156hp and 111lbs at the wheels
93 integra Rs full interior
JDM B20B
YS1 w/LSD
Fidanza aluminum flywheel
ITR PP and disk
test pipe
K&N drop in filter
all season 14" tires
all else is stock
dyno: 140hp and 135lbs at the wheels
The heavier DA stayed a half car lenght ahead till the top of 3rd gear when the EG started to catch up… this was repeated 3 or 4 times in a row, from a standstill or from a rolling start.
So I imagine that stock for stock (EG had all the bolt ons and ECU tuning, DA had nothing) the B20 would get better times.

Off the line a B20 will kill a B16. But once VTEC kicks in the B16 is making a good bit more power. By the end of the 1/4 I think it’d be ahead. Around town the B20 will feel quicker since it has a more useful powerband.
A stock B16 makes how much more power than a stock JDM B20B???
The B20 not only FEELS quicker, but it IS quicker…

If trannies were equal, the b16 will then have the most useable powerband because if the b20 redlines around 7000, the b16 tranny will catch around 6200rpm or so between shifts and even 6500, only have about 1000 more rpm to rev as oppossed to almost 2000. That’s why honda gave the b20 a longer gear ratio.
hey brekekex, i think you posted the stats on the JDM B20B on another post but im not sure. what are the numbers of a stock JDM B20B? also where did you get you info on this engine.
thanks

Is that why honda gave the B20 a longer gear ratio? Thanks… that explains the stock non vtec integra ratios too I guess…?
My tranny has closer gears than the EG’s CTR tranny… and his redline was nearly 9k, mine was at a stock 6800rpm.
Short gears rule on pretty much any small displacement naturally aspirated engine. The B16 has a higher redline, but so what when the power output is ultimately less?

Man, here’s from actual experience. A B20 car with a GSR tranny (my hatchback w/out the turbo on it, before the H22) ran much faster than a B16A hatchback… I’m talking like 4-5 car easily. I ran a 14.1 on street tires with just intake with my B20 hatchback w/GSR tranny. I could even pull on modded Integra GSRs w/bolt-ons pretty easy on the highway. Even though the B20 doesn’t have VTEC, it still pulls like a mutha. If I had to seriously decide between either a B16A motor or a B20 motor (US B20Z or JDM B20B… same chit), I’d get the B20. Not only does it “feel” faster, but it pulls so much harder than a B16A car, even when the B16A car is in VTEC… this is from personal experience.
" Which is faster? B16=horsepower VS. B20=torque??? "
Im sure most Honda tuners agree, in NA…
Its easy to make more HP, but its not easy to increase torque.
The way of increasing the torque is through displacement.
B20 already has balls.
Not tryin’ to start any beef or anything, but…
In NA, displacement wins. B20
Exactly, all you have to do to increase hp is to continue making the same amount of torqe (or even a bit less) at a higher rpm. Enter vtec - Honda’s little gimmik to take advantage of gearing to make a low torque car faster (and “sound” more impressive with the artificial hp ratings). And it works too.

Anyone got any b20 times for DA?
My b16a ran 14.909@92.6 with b16a,headers,intake and chipped ls ECU. 144 whp.
I’ll take a b16 over any ls/b20 since it revs like a tractor compared to the b16. Sure, the b16 makes the power higher in the powerband but it get there alot faster.
BTW I got a 1.8 right now
B20 NA has that potential too. In fact, a stock B20z with i/h/e & FPR can make 140 whp, but along with 135 Tq. Add higher cam profile and it can keep the Tq flatter in the highend. This is enough to park the B16. B16 cant get more than 120 ft-lbs to the wheels.

Hehe… a tractor huh? Heh… educated comment no doubt.
140whp with no bolt ons on a stock B20B… oh, and 135lbs at the wheels… I like tractors.
I assure you, the B20 gets there faster.
"In fact, a stock B20z with i/h/e & FPR can make 140 whp, but along with 135 Tq. "
Hehe… those are JDM B20B numbers with NO bolt ons… stock exhaust. Only mods are: K&N panel filter, and a test pipe.

Oh whoops, better than i thought.

IF you ever had a b16 you would understand what I’m talking about.
You got a K&N, I got dirty filter on stick
I got $120 header, you got a test pipe
big deal,the b16 will make atleast the same hp stock as a stock “JDM” b20.
So no one got any times for their b20s?
I dont think b20 is bad, it just isnt all that(not stock anyway). Especially since you probably paid twice as much for b20 long block as I paid for my complete b16a with tranny.

Haha… funny how you assume what I had or did not have, or what I do or dont understand.
I will assume you have never been in a B20 powered car… tell me I’m wrong, becasue I KNOW you dont understand, which you proved with your “tractor” comment earlier.
Thats fine, stock for stock the B16 makes the same hp as a B20, and it also makes 30lbs less, you know… torque?
And yeah… I definitely paid more for my B20 than you did for your B16… but thats the price you pay for a 1 year old engine as opposed to a 10 year old engine. Tell me what a 8 year old 2nd gen B16 is worth, and I assure you its gonna be the same if not more what a 1-2 year old B20 is worth.
Cannot say whether or not I paid 2 times more for my long block than what you paid for your complete B16 swap as I do not know what you paid for it… but if your assumption was right, then damn man, you got some pretty HOT hookups.
Anyways, no time slips here as the 1/4 mile does not tickle my pickle a great deal… but a few runs with a friends B16 powered EK Cx h/b made me relise that I made the right choice with my swap.
Anyways, having said all that, a B16 is a hell of a lot of fun right out of the box, no doubt.

Did you get the B20 inn Toronto? I’m trying to figure out how much one of these things costs and where to get them in Can.
thanks

You are wrong.
Its not an opinion,it a fact. LS/b20 revs like a tractor compared to b16.
If LS/b20 shitty rod ratio would have been a good base for a performance engine there would have been no need for honda to develop the b18c.(yes I know that the b20 came after the b18c but the crank/rods, which is the reason for my comment,is the same as the LS). BTW the b18c doesnt rev like b16 either,but its better then the ls/b20. No wonder honda scraped the b series for 2 liter performance engines.
Also, look at what kind of vehicles honda developed the b20 for.
This concludes my participation in this thread, but I’d still like to see b20 times if anyone got them.
