What is the deifference between a B16a, a B16b? What are the advantages/disadvantages? Pros and Cons?

Z0831xiz

if I understood right.
b16a is a obd0 first Gen vtec engine
while b16b has same components as b16a just longer rods and taller block which would make higher compression. and b16b is a jdm spec engine that is obd2 I think?
I'm unsure. but thy both share the same crank and pistons

Thanks heaps . Which is better?

Orangevirus1

isn't one of the B16's a Type-R engine

Bradman

Im not sure. but i plan on putting the better one into an EF civic hatch.

b16lewis

the b16's are not all the same. the ones that came in the us cars have 10 less horsepower because of the cr difference. the b16b is the ctr motor. this is a completely different beast. rods are longer than the b16 a's , the head is ported from the factory, dual valve springs, different cut on the valves, better cam, higher cr. and 25 more hp than the usdm b16. now if you are going to buy one of the two and slap on the typical parts, i.h.e., so on so on. I would but a full ctr swap. but if you plan on any internal modification buy the b16 a. because aftermarket rods for the ctr are about 800 bucks. just saying. but if you are in it for the type r hype I would buy the itr motor.

b16lewis

o and the b16a is also available in the 92-95sir.

Bradman

oh cool thanks for the info. sounds like i want a B16a then probably.

b16lewis

I have owned 3 I have one in my car now. can not hurt them. I would recommend buying a transmission with a lsd

If you want the best motor honda ever made, buy the B16B.

If you want a great motor, and dont want to pay more than the entire car is worth.... Get a B16A.

b16's are pointless unless you boost them, they have the shortest block and shortest rods, but they rev to the moon!!

A b16b is a JDM civic Type R and uses the same block as a B18 Type R, being a taller block, it them uses ALOT higher compression pistons (pointed like) and this engine has a little more power, but revs even higher.

please, do tell how it is honda's best engine ever.

b16a ef 88-91(with dohc words bigger than vtec words is first Gen b16a)
b16a eg 92-95(with dohc smaller than vtec words . vtec being bigger words second Gen b16a)
b16a2 is the em1 civic engine
and b16b is the mighty civic type r engine which is best in my thought but its a bigger engine than most b16 due to block size

I am curious as to how the b16b is the best motor ever

F22Master

Almost ideal rod/stroke ratio
Internally balanced for higher rpm and to a better tolerance (than b16a)
Ported and polished head (same as ITR)
Lighter valves (same as ITR)
8400rpm stock redline, will handle 9k all day long no problem
115hp/liter (more than ITR)
Also has one of the best transmissions honda made. Close ratio 5 speed with LSD

In my opinion, it's the best engine they have ever made (for production vehicles).

b16lewis

the b16a handles 10k with no problem, and the transmission thing that is a matter of opinion. the greatest thing about the ctr is the head. the money you spend on a ctr swap you can spend on the b16a and out preform the ctr all day long

F22Master

No, it doesnt. Not with stock valvetrain. And yes, the extra $1500 or so (going by HMO prices) could buy you a good turbo setup, in which case you could outperform any 'stock' honda motor. But that is not what is being discussed here.

Stock for stock, the B16B is the best honda motor. Not most powerful, not best to mod, not cheapest, none of that. It is a high revving small displacement engine with a high specific output.

b16lewis

yes it will mine does

Fliptard

that motor won't last long, unless it very well built and balanced

F22Master

*cough*like a b16b*cough*

Fliptard

B16B's are nice engines, but price vs power, You might as well buy at Type R swap.

If you like to rev to the moon and beat the **** outa a stock motor, get a B16B

If you want more power and don't care to rev quite as high, buy a Type R

Could not agree more, I absolutely love my B16b, 8,400 is redline but factory limiter is set to 9k.

The tranny isn't really a matter of opinion, the 4.4fd, dual synchromesh 2nd, 3rd, 4th gears, and a helical LSD from the factory makes it a dream tranny, although I won't lie it kind of sucks on the freeway at 80mph.

There is over a 1k difference in price between a b18c5 and a B16b. I got my complete b16b swap for $3,400 shipped with 61,xxx kilometers on it, even came with a mugen header.


BTW, I owned both motors at the same time, I preferred the b16b over the c5.

b16lewis

what I ment by the trans bring a matter if opinion is the itr with the 4.7 final drive and with the 4.4 final drive are also wonderful trans. yeah the 80 on the intrastate does suck. I have the ctr trans so I feel ya

F22Master

B16B is $3600
98 Spec B18C is $4500
(from hmo)

$900 for 15hp is such a great deal...
