Ahh… so the B18C r/s ratio is soo far superior to that of the B18A/B20?? I guess, in your oh so very educated opinion, the infinitesimal numerical increase in the B18C’s r/s ratio is what makes
Haha… dude, its a good thing that you will not participate in this thread any longer… you have had nothing good to contribute to begin with. But, I’d love to see more of what you have to say, its quite amusing you see. Please do continue contributing.
"Its not an opinion,it a fact. LS/b20 revs like a tractor compared to b16. "
Its a fact? Can you back that up with a mathematical equation?
Damn, the ignorance is blinding me!
And its not an opinion, its a fact that you were merely expressing your opinion… a very uneducated one I might add.
I wouldn’t be so inclined to say that Honda scrapped the b series engines in favour of 2.0L performance engines. More like Honda scrapped the small displacement engines (we’re up to 1.7L civics, more torque, same hp) for larger displacement engines (2.0L RSXs). Granted, the cars seem to be getting a little heavier, but put the B16A in an rsx and it’ll probably rev like a tractor compared to the B20 (w/same tranny). The B20 may sound like it’s meant to be a dog engine, but consider the vehicle we associate with it. the CRV. Fatter larger Dia. tires, aerodynamics of a brick, more weight. 4 wheel driving and the transmission of a tractor. The engine is essentially the same as the b18, cept with wider pistons. Shouldn’t slow the revability down much, its making a lot more torque to help twist.

In NA, it is not a matter of how fast the crankshaft revs
it’s Piston Speed that matters.
Think about it… for each rotation of th crank, Piston speed is much faster in the LS/B20 bottom.
B16 bottom is much easier to rev because of its short stroke geometry, but does it displace more AIR? NOPE!
That is why short stroke is good for FI. Allows more boost to “fill in”.
horsepower wins dragraces
torque for daily driving
B20Z gets my vote
As an owner of a B16A powered vehicle, I probably wouldn’t do a B16A into a G2 unless I could go I/H/E and a set of Toda cams with a Mugen program in the ECU
now that’d be gangsta
Unless I could get a B20Z (which is going to be newer with lower K) with Crower 403 camshafts, upgraded valve springs and retainers and increased rev limit.

Learn to read before you post again. I didnt say b18c was far superior to b18/b20, I said it was better, which it is. Thats a fact.
I still prefer the b16 ,thats an opinion, based on experiences from having shitty r/s ratio engines in my car.
You are entitled to your opinion, you dont need any experience to have an opinion. Since the laws of physics dont apply to you, I’d suggest you go all out and get b20a5 crank for your engine, that will give you mad torque!
"Ahh… so the B18C r/s ratio is soo far superior to that of the B18A/B20?? "
That was a rhetorical question… it is there to make YOU think.
I figured you are sharp enough to catch that, but I guess not. =/
You mention the r/s ratio as a factor in its non-performance like nature… did you not? If so, then think about how much better the r/s ratio of the allmighty B18C is.
THINK before you post again.
"You are entitled to your opinion, you dont need any experience to have an opinion. "
Bhahaha! Sure you can have an opinion on a subject about which you clearly know little about… its called IGNORANCE.
"You are wrong.
Its not an opinion,it a fact. LS/b20 revs like a tractor compared to b16. "
I will ask once again, as I see you missed it the last time.
how is it a fact? What is it that you have to back that fact up other than the nonsense in your posts?
Something tangible please.
Now, I could easily say “B16A rev like Caterpillar dieles generators, and you like big hairy sweaty nutsacks”
hey… its my opinion!
"based on experiences from having shitty r/s ratio engines in my car. "
Hehe… and what experience is that??? It made too much torque for your liking?
Damn… my opinion is that you have read too much superstreet.
man this is pooty…take the best of both worlds…go to www.crvtec.com and look around. torque is tight to have, as well as vtec, i have a b17a w/182k and i wouldnt trade my vtec for anything other than another vtec or a b18 turbo:). you all seem to have good info, yet some g2icers seem to bicker like children at times over whos is better, the way i see it, as long as its in a DA, it cant be but so bad!
my advice: be happy that you have a honda motor, assuming you dont have a 2.0 outta an old lude hehehe;
------ or-------- go buy a chevrolet camaro–aka the cheapest quarter mile car in the world(no i dont have one nor do i want one)
Okay, these bickering posts are getting a little out of hand. More bashing going on that constructive posting. I feel like a teacher breaking up a squabble on the playground. Clean it up guys…or I will.
Now I will add my two bits. There’s a lot to say for torque. I think a better quote would be that “torque sells cars”. That’s what you “feel”. Torque doesn’t always win races, but it does help in most cases. I have beat many cars with more torque than me and about the same weight. I just had more hp, better gearing, etc (my driving skills probably came into play a little too :D).
I have never driven a B20 powered anything, so I can’t speculate as to how it compares to a B16A. But being that the B20 is stronger than the B18A, I would have to say that the B20 would give a B16A a run for it’s money if not win. But both are great motors for swapping. I think because the B16A is cheaper, it would be my choice if I dindn’t have or couldn’t afford my setup.
But if I had a choice between a B20 or a B18C, the B18C would win me over no matter what. I’ve been sucked into the VTEC pool…and I can’t get out :p! I’m hooked. Besides, it’s a cool feeling to rev to 9000rpm.
Push comes to shove, you can’t go wrong with either setup. Best of luck.
i read somewhere that you can use different cranks for the b20 block, such as b17a, b16a, etc. woudlnt a b16a crank give you a really good r/s ratio, making it basically a bored out b16?
ive raced b20 and b16 swap civics and the b20 seems abit faster from torque. for the b20 against the b16, i think by the time vtec is trying to make up from the b16, b20 is through w/ 1/4. b16 wont make up the lost. vtecs not as hard.
I think if everyone here arguing about which is better would take a time out and do some definitive research on engines in general, there would be no debate whatsoever becuase you would understand that there is no definitive answer to the question.
And either way you go, the difference in drivers will win hands down if oyu had one lined up against another.
There is no reason whatsoever for anyone to be so adament about something so preference-based. If your only goal for oyur car is to go as fast as possible in a strait line you would have bought a race car and not a street legal car. No matter what setup you have unless you purchase a flat out race car, you will always be giving up performance for reliability. This is truly silly
