B16A1, B18B1, just did a "torque vs horsepower" search and found some interesting stuff!
I had my mind all made up to get the B18B because of the extra torque, then I found this:
http://www.vettenet.org/torquehp.html
"...It is better to make torque at high rpm than at low rpm, because you can take advantage of *gearing*..."
Now it looks like the B16A1 is worth the extra $300 it cost to have it installed! Even if you don't tach is to 7K in daily driving, if you need it you will have a BUCH of power and be able to stay in a gear longer! (assuming I read that right
)
What kind of RPM's does a "normal" B16A1 turn at 80mph? (I know it depends on the trans, just looking for a comparison to the D16A6/Si (~3900rpm@80mph)
Comments? Input?

I have a B16a and I'm pretty happy with it, but if I had to do the swap again I'd do a B18C. I'm turning 4500 rpms at 80mph with a Y1 tranny.

b18b is a beefed up zc. 2lb less torque than a b18c5. zc's will kill a b16 up to 60-80mph then b16 pull hard on em. b18b will kill a b16 to about 75-95 mph. low end torque is a must for good starts. b16 will beat both zc and b18 in long run b/c high end hp always wins (depends on distance but eventually it'll win) b18b will most likely beat a b16 in 1/4 mile
Tortex: I really don't understand this idea where you're trying to correlate low end and high end power to vehicle speeds. Yes, the B18 has more torque and power down low, i.e. less than 4500 rpms, but when I'm racing someone I am always in my power zone 5200 to 8200, and the car has the same power no matter what speed I'm going.
The only thing that would make a difference at higher speeds is aerodynamics and gearing. Engine output is directlly related to engine speed, NOT vehicle speed.
Could you do some more explaining.

As far as torque vs. hp, torque is a measure of rotational force while horsepower is a measure of work. To get hp you use (lb-ft * RPM) / 5250. The common misconception is that torque is what creates low end grunt and hp is what creates top end. The expression "this motor has a lot of torque" and such pretty much relate to the amount of torque produced by the motor at low RPM. HP is a function of torque and RPM combined so obviously if a motor makes lots of torque at low RPM, it will also have relatively high HP at low end.
Instead of comparing "torque" and "horsepower" it would make more sense to compare powerbands i.e. "ZC's have beefy low end" or "B16's have nice top end" etc.
ZC = D-series block. Not B-series.

That page, by the way has a lot of BS in it, and just a little fact. I've seen the exact same thing written all over the place, too. For example, one of their claims is that an Integra GSR, LS, and if you follow the logic, Type R all feel just as fast, but magically the Type R, then the GSR, then the LS end up first at the finish line.
The Type R is and feels faster, even though torque is very comparable. Put an accelerometer (like a G-tech) in these cars and you'll see the difference in G's being pulled.
If you anyone doesn't believe this, understand that a Toyota Prius has 340 ft-lbs of torque. Test drive the thing, and see if you can still make the claim that it "feels" faster, but really isn't.
Also, my B16a CRX will PULL on a ZC CRX at any vehicle speed.

video is in the members corner.
and yes i understand that the zc is a d series and b18b is a b series. b18b is a 1.8L b series version of the zc. different compresion ratios etc (obviously) but im sure you get the point

Say a b16 has a vtec x-over at 5200k.. how long does it take to reach vtec from launch?? NOT LONG! So because it develops its torque later and has a broader torque band (higher revving) then by "definition" the b16 is faster.
remember "definition" can offen be different in reality.
Shoot i've taken out any EF/ED with a zc and b18b that's faced me. Okay especially the zc. And what crx7 meant is as soon as the tires grip he's in the power band and every shift after that he'll still be in the powerband. Also to say what car will pull in the beginning will actually depend on two other things besides the motor, the driver and the tranny. That is the main reason the b18b is slower, lets say you put in a b16a tranny on the b18b then you'll have a better chance at beating the b16a. And don't forget that the b16a can rev higher.
Yes barely pulling Jesse, but the Maxima has some mad torque.
Hey Tortex: I'm just wondering, do you have a car? Have you ever driven a car? Have you ever driven any of the cars you claim to know so much about(i.e. ZC, B16, B18b CRX's)?

to give tortex a lil credit, torque is amazingly deceptive.
Driving your crx and then driving the Maxima, even back to back, it wouldn't *feel* like the CRX would be able to edge out the Max.
Different power curves.

um yeah why you think im saying zc and b18b's smoke b16s off the line at up to about 60mph? ive seen it and driven em.
I got smoked by a d16z6 when I had my n/a B16a....
...after I put in ITR cams and intake manifold, before tuning... and he worked at COMP cams with a 93 Si with a cam, retainers, Flywheel, and other fun stuff like that...
That was a quick D16z. <Even though I was probably running a 16+ at that time, damn fuel tuning was WAYYY off>

My d16a6 with bolt-ons will roast a ZC with bolt-ons.
I've got to disagree with a ZC taking a B16a off the line. A B16a makes more torque than a ZC, and it makes close to its maximum torque throughout the entire powerband. A B16a is faster than a ZC at any speed. ZC pulls on a B16a til 60-80 brotha pullease.
Uh, maybe it's the gearing? Who knows. Probably the driver.
I guess everyone besides Lsos got caught up in the "my car is faster than yours" talk and didn't bother to pay attention to the relevant information that I posted on what the hell you should actually be talking about.

Let's GET This Straight! A vehicle will NOT accelerate faster at lower vehicle speeds if it has more torque. A vehicle will accelerate faster from lower rpms if it has more torque. What speed the car is going has no correlation in these matters. Do you not understand?
By the way, how old are you Tortex? Did you go to college? I understand that a car with more torque does feel faster and that may be what is misleading you, but this thread is really beginning to annoy me.

The Maxima he's referring to has 220Hp and probably runs high 14s which is what most b16a crx's run high 14s maybe low 15s sometimes. ZC's run mid to high 15's. I don't know about b18b's.
