What are the big engineeing differnces between teh B16a1 and the B16a2. I know all the specs and hp ratings, so don't post dumb **** like that. I want to know about flow and engineering differences like combustion chamber cc's and volumetric efficiency and everything else.

 

Ports and CC's are the same. The difference is the cams and pistons. Also the head has cast cam covers. The oil passages on the block and head were improved in the 92+ B16A also.

 

were the oil passages really that much of a differnce?

I don't really care much about the pistons and such. I am going full drag all motor on it. I will just use other ones.


THANKS!!!!!

 

Also if you are getting it with the tranny, the b16a2's have a hydro the 1st gens are cable

 

if your gonna go full drag i take it this isnt a daily driver? cause if its not throw an h22 in that bitch.

 

wow, really H22, never heard of that engine!!!.............duh!!!

don't post unless u got something good to say!!!!!

 

What's an H22? ROFLMAO ;-)

 

dont be an ***
all im saying is if this is gonna be a drag car get a bigger engine. you can get an h22 for the same price or less than a b16

 

I am an ***, get use to it.

I just hate when peopel post dumb **** just to sound smart, like "get an H22"


Kaotik.........didn't know your dumb *** posted on here. MIGHT get an eg instead of the DA now. no more B20

 

some might say ***, I would say worthless piece of ****...if you are going to be a ********, do your own ******* research

 

thank you drag.

 

lol

grey plug, yellow plug... grey plug, yellow plug... grey plu

 

**** the B16. There ****. Why dont you stay with a D15 motor. It sounds like it would be your kind of motor.

 

You make yourself sound so smart but why are you wasting your time with a 1.6 liter engine. Obviously someone of your mightly intellict would have realized that the old saying"there is no replacment for displacement," Could not be more true. Yes you can make a b16 engine fast, but just imagine how much faster you could go if you spend all the time and money your planning on spending on the b16 if you spent it on a b18 or h22. But of course this is all dumbshit that you know already. Right? SO WHY WASTE YOUR TIME WITH A B16! it just doesn't make any sense. if your going drag than bore out a f-ing prelude engine already!!!

 

Maybe he does not want to worry about traction problems with an H22. It is not easy to put all that power to the ground in a front drive car.

Would you say that Rev Hard is waisting their time? This is straight from Turbo magazine...

"The Prelude VTEC pounded an earth shattering 680 horses to the front wheels. Unfortunately, the crew was unable to adequately put the power to the ground..."

"...With lessons already learned from the Integra, the Civic was only going to be outfitted with a 1.6 liter, B16A engine..."

"The choice proved beneficial, with no broken driveline parts at the very first outing where the Honda made its quickest pass of 10.24 at 138 mph-with a slipping clutch. With the clutch changed, it was again time to bring the Civic to the track. On its second outing, the Civic was able to blast into the coveted nine-second club with a 9.92 at 142 mph."

See, bigger is not always better. Not everyone can be Stephen Papadakis and have nice big sponsors to help them out when they break things either.

I would also like to know the differences between the two engines. I always thought it was just the cams, compresion ratio, and the emissions control.

 

IF a h22 wasn't favorable(you made a good point about that)than at least a b18c1 or c5 dare I say so.

 

Well, if you look at both engines you will notice that they both have the same bore. This means that they are both capable of close to the same hp. A lot of people say that torque is what wins races. Well, when you dont have rear drive and are in a sub 2000 lbs car, torque becomes less of an issue.

There is also the issue of money. Maybe he wants to build a budget racer. There is also the fact that he may want to do more of an scca type racing. Both of these categories will go to the B16.

Not only is the B16 cheaper (making it good for the budget end), since it has the same bore as the B18 you are not losing out in the horsepower department. That is assuming you are going to modify the engine. It may be at a higher RPM than the B18, but who cares if you are going to be around you red line most of the time anyway (road course racing).

If I am wrong about any of this, please correct me.

well the way i see it is that torgue is always an issue. even if your in a sub 200lb car it just makes it that much more valuable. but a budget racer. he said that we wanted to make a drag car I belive. Well that sure aint no budeget racer. But the more I think about it the less a h22 seems like it would be any good to use unless your steph or rado or someone like that with a bottomless wallet. I would go with a b18 block, nodoubt. all does is mean a little bit of delay in the time to get the engine in order to save up for it is all. I wish this guy would respond to this little discusion here in order to put ourbickering to an end

 

He is just the silent type I guess.

The B16 vs. B18 battle I think is more relevant if the car is intended to be N/A. If the car is N/A I can see the major advantages of the 1.8 liter block as opposed to the 1.6. But for a turbo setup, I just dont think that the cost can be justified.

First, if you want a reliable engine with turbo, the rod/stroke ratio is going to be brought up a lot. The B16 is very turbo friendly with its near perfect rod/stroke ration of 1.74 to 1. The B18 is going to have more of a side load problem than the B16. A lot of people would say that using a block guard in the B18 would help, but what about the hot spots at the top of the deck? This is also putting extra cost on the setup.

Then there is the flow. Everyone knows that the B16 and the B18C5 share the same head. This is because the B16 head naturally flows better than the standard B18C1. So, why not just get the B16, slap on a turbo, and have some nice hp numbers.

Of course, if you are just using this for race purposes, the torque problem can be solved with a little bit of Nitrous Oxide. That is a nice cheap alternative to the 200cc's you would gain by spending close to $2000 extra (assuming he is getting the 1st gen B16 which can be had for 425 bucks for the long block).
