B20 myths.

[AK_CRX]

Im glad to see people on this site not putting down b20's, its a nice change from other forums The b20 even in stock form is a bad ass motor, I was running consistant 14.3 with mine, it was stock other than using oem 93 integra LS cams (slightly more aggressive) intake, chip, and no exhaust. I was running mine obd-0. Also good to see that somebody else in this world knows that a stock B20, even the low compression b20b, even with an LS tranny, will OWN a stock b16 with short gears (S1, J1, Y1). If I was running b20z compression ratio with a y1 tranny I know I could have hit 13's... I really miss that engine, need to start putting one together

No, it will not, not without a good driver. B16A's in low level full interior hatchs with bolt ons and a good driver have run high 13's low 14's. It will come down to who has the better traction/launch and can get through the gears faster, not to mention keeping a B16A in the powerband isn't real hard. Don't get me wrong, I like the B20B/Z great motor and they go cheap so it leaves a lot of cash left over to mod them. But some of you are talking like it's going to put bus lengths between on a B16, and it's not, like I said before, it is going to come down to driver.

Never said a b20 was better than every b16 in the world, I am only saying that I have YET to see a stock b16 or a b16 with comperable mods that I had run a better time than me (14.3) And they have a short geared bad ass tranny to their advantage... b16a's are great motors, and I realize they have great potential etc, but stock vs stock I prefer a b20 all day long wether its at the track or daily driving. Ever seen a stock b16a that can spin the tires into 4th gear? Not that this means its going to be a faster car, but it does mean that this engine makes torque that b16a's can only have wet dreams about. How bout a 2.23 60ft, on street tires, launching @ 2,200 rpm? Most honda engines would fall on their tits if you launched them @ 2,200. As a matter of fact, a b20 makes more torque @ 2,200 rpm than a b16a makes at PEAK! I think about it like this...
b20b/z: fatty torque curve(more of a straight line) from 2,500-7,000
b16a: lots of horsepower from 5-8,000 rpm

In my eyes the b16a in stock form is a one trick pony, it goes really good from 5-8k rpm. I've been trying to figure out for years why people have such a hard on for b16a's

haha amen brotha i building my b2o right now b16 is over rated just like the z3 fenders...lol

[lilol89crx]

ill go with the b20....i want more tq! but my ls outta do nicely for now

[jcrx]

Well, you have fun, it's obvious you have never driven a B16A as it has a nice bit of power even below 5000rpms. Maybe mine is a weird one. And I can live with only chirping through third.

hey i found somebody whos selling a b20b motor and he said just to tell him what kinda tranny i would be using and he would send me axles he said it has 30 to 48 thousand miles on it for 450$. so my qeustion is that worth it? and what else would i need to make it work in a 91 civic si. With and intake exhaust and header im geussing id be maby running low 15's (please correct me if im wrong). your help would be greatly appreciated! thanx

[IceCold]

which of the b20's is vtec?

i was told that none of the 2 liter CRV engines came with vtec

[jcrx]

There is no vtec B20, but people make them all the time.

[IceCold]

so you take the bottom end of a b20 and put a vtec head or something?

Yeah, try reading the first few posts.

I have found quite a few different B16's out there. Some that are not as strong as others, others that amaze me. But overall, I am seeing more and more "weaker" 1st gen B16's.

Overall, if it came down to me choosing between a B20, and a B16A. I would choose the B20 again, hands down. I was very impressed with what they can do.

Also, you cannot compare time slips with people on a worldwide forum. There are so many enviromental factors that take into play. Elevation, RH, etc. I could drive the shit out of my B20, not vtec hatch all day at the track, and not break into the 14's/ Yet I take a trip up to Washington, and the time dropped into the mid 14's. I sure as hell didnt learn to drive any better between that 10 hour drive.

Bore it out and the r&s will turn out better. A buddie of mine put a B16 crank and rods and a lot of machine shop work into his B20 and it comes out to a 2.2 w/ r&s of a B16. he can rev to 12 grand before the motor started testing for stress equal to 9 grrand on a B16

whered u get that from? cylinder bore has nothing to do with r/s ratio. now i can see the r/s with a b16 crank and rods but not only by boring it out. also it would have to be bored/sleeved fairly large to get 2.2 outta a b16 stroke.

[freakypn0ylykhoy]

what is the best head to put on a B20???? i heard a b16 head is better then a GsR heaD but what about a Type R or Prelude Vtec head????

[crxtacy]

prelude head wont fit on a b series engine.

so givin 3 crxs, 1 with b16, other with b18 and the other with b20. it will pretty much be a drivers race?

what about a b16 tranny to an ls?
