Default Question on b16 vrs ls.

I see a lot of DA integras doing these swaps. My question is why? Dont u loose all the torque in the world when u do that. I see a lot of this so i was just wondering. And i searched. nothing came up. so please enlighten me. And i am talking about FULL b16

I think the b16 swap in the integra is a waste of money but thats just my opinion,ls/v or b20/v is the way to go

I agree. But my thing was, is that why would they do it lol. I would think a ls in a hatch vrs a b16 in a hatch. or in any cars realy. the ls would win.

Based on my understanding, the reason why people are swapping B16's in their DA is because the shell is lighter than the DC model. Some even compared the DA chasis to be lighter or similar in weight to the 99-00 SI. Now on the other hand, a B16 inside a DC chasis is unquestionable unless that B16 was stroked or boosting.

But then again, considering the hype about Vtec on this forum. Maybe because they just want to have Vtec. But then again, who needs Vtec when Crower makes 404's?

On a different note, an LS with a B16 tranny will outrun an LS Vtec set up running the lazy *** LS tranny. Yes the LS head does not breath as efficient but the main variable why the LS feels so "sluggish" is because of the lazy *** gearing the LS tranny has.

my buddy has a 92 da with b16 in it and its slow as ****,with the money it cost to do the swap you could build up the non vtec...if i was going to do a straight up swap with a DA i wouldnt throw anything lower than a b18c or b18c5

i totally agree. And the 404's. those might be what i put in. I wanna see a fully built head on a stock bottom end ls and see what it puts down lol. i have seen some that are built. with no port and polish. or built, with no cams. lol. none fully done up

i am doing a b16 swap in my DA based on my buddys first hand experience.

he has a 94 LS and owned 3 DAs before that, he finally decided to build up an LS instead of swapping it with a b16 or b18c, which he had done with his previous 3 DA's. he has crower 403's, crower springs and retainers, skunk 2 pro series IM and throttle body, DC race header, port and polish, and tuned on hondata, pretty much built except for some higher compression pistons.

i asked his opinion strait up before i decided what i was gonna do with my car, i asked him "so what do you think of having an all motor LS" he said " i should have gone turbo or swapped it right away instead of WASTING my money building the LS", he said "if you have a DA go with a b16 if your budget minded or go b18c if you can, for a DC, b18c is the only way to go" i asked him thats as we were putting a turbo kit on his car so therefore ill go with somebodys opinion who has experienced every aspect firsthand rather than going by what internet know-it-alls type from their desktops

alot of times it is personal preference, thats why alot of people that go all-motor LS say they are doing it to be different, to do something different. but the motor with the ultimate higher HP potential, and better flow characteristics is without a doubt the b16 and b18c's, period

The '99-00 Si are about as heavy as the DC. The DA should be a bit lighter than both but not by a huge amount.

Grab a gsr. Cant really go wrong there. ITR swap is too expensive, people complain about the b16 not having enough torque, the LS has crappy gearing and no top end, and the BS never ends. So go get you the gsr.

I hear what you're saying, your buddy had a SEMI built LS and was not satisfied. I would not be satisfied either. Because it's common sense that you will not get the most out of your cams without bumping up the compression. 403's don't require much compression but 404's do to get the most out of them.

I myself have friends that are running built/semi built LS's and for the total cost it is a lot cheaper than doing a vtec head swap. You don't beleive me? Do the math; PR3 pistons, 404 cams, manifold along with an intake header and exhaust tuned will outrun a B16, B18, or B18c with bolt on's. I've seen it plenty of times. Ask any engine builder.

On another note, was your buddy still running the lazy as long geared LS tranny? If so, then I rest my case. Give an LS a B16 tranny and it will accelerate much better even with bolt on's, even better if the LS motor is built.

To say the B16 is considered Top dog is joke right? You mean the torqueless wonder 1.6 liter? 1.8 and above unless your boosting or stroking to 1.8 or 2.0.

By the way, there are plenty of LS's around So-Cal that would make any cocky Vtec owner question the title of their GSR or SI.

The N/A LS might beat bolt-on GSR's and what not, but if you wanna go built GSR vs built LS than the LS has met its match.

Ls bottom/b16 head thats the way to go... i had Ls turbo before this, but the LSvtec -t has never made me happier. just got it back from getting tuned today and my last set up was nothing compared to this one.

yes, exactly, the XSi came with it, no doubt a built LS can be quick but all im saying is built gsr will own built LS all day long, in the end run a gsr with a GOOD I/H/E and set of cams, tuned will beat a built LS, but if you bring in the price of the swap, it becomes quite pricey, it all really comes down to personal preference, goals, and cash flow


btw my buddy ran a 14.9 with a slipping clutch last summer, in an LS-S with leather and all, not the lightest of cars, and he had the LS trans, so no doubt it was quick for a NA LS, it just wont stand up to a gsr with equivelent (or however you spell it) mods

Yes, I was referring to you. Unless I misinterpreted your statement that mentioned above how B16's and B18's (Vtec motors) are the ultimate motors for horsepower potential.

I agree no doubt built GSR is faster than Built LS. The proof is in the pudding; the GSR is already given a better platform. There is no arguing that. My point was for someone to already have an LS and to shell out extra money for a B16 or GSR swap is just wasting money. Especially if you already have an LS motor that can be built or worked on. Like I said, the price of PR3 pistons, 404 cams, intake manifold and bolt ons is CHEAPER than a Vtec head swap and way the hell cheaper than a B16 or GSR swap. Like you said, "including the price of the GSR swap it can get pricey", yes indeed.

Now let's compare a stock B16 to a stock LS motor. I'm sure you guys have seen the factory torque curves of the B16 compared to the LS motor, if not it's floating around some where around here. Now despite the lack of Vtec of the LS motor the dyno graph clearly shows you that the B16 got spanked all over the ENTIRE rpm range in terms of TORQUE even though the B16 had higher peak numbers. Who cares about peak numbers? Torque is what ACCELERATES the vehicle. In other words, that LS motor would outrun, yes I said outrun a B16 despite the almighty Vtaaaaaak.

Another thing, the reality is until you've driven an LS with a Short geared tranny like the B16/Type R tranny you guys have no idea about how respectfully quick an LS can be with only a simple short geared tranny swap without Vtec. I mean seriously, it's sad to hear people say Vtaaaak this or that. Come on now, let's go with first hand accounts instead of word of mouth shall we?

For example, when my LS with bolt ons and a B16 tranny would run my buddies JDM GSR swap with bolt ons in his DC (since his LS motor hydrolocked) you should've seen how dissappointed he was to find out that his car was neck and neck with mine. Numerous times consistenly the same results. Hell, he even drove my car for a while and said for stop and go driving my car was more enjoyable to drive because of the CLOSER gearing that makes accelerating and upshifts that much better.

On a different note if you ask me, I say go boost if you already have a motor. For the price you can outrun plenty of cars. That's the route I recently did and I don't know why I didn't go this route a long time ago. Even at gas stations fellow N/A GSR drivers would say "how I would get smoked just because my LS-T does not have Vtec?" It's comments like that, that has made me not even want to use the word Vtec anymore. LOL..seriously. A bunch of Vtec Bandwagoners.


Stock LS-T boosting 10 psi with only a B16 tranny giving plenty of cars a rude awakening . I'm a modest guy so I'm not gonna create a kill list.

Go check out the LS-T thread and plenty of the guys there can VOUCH that the LS-T is no SLOUCH. Yes, even when matched up to GSR-T's.

But I agree, it all depends on what your goals and bank account looks like that will dictate which route to take. Because the reality is, any car can be built to be fast so let's not EGO trip about Vtaaaaaaak.

Well spoken! I'm loving my broke *** LS setup...cai, hytech replica header and ITR exhaust, all mated with a GSR tranny equals a pretty surprising little dc4. Almost makes me wish I got a b16 tranny...almost

thats what i said, i meant stock for stock, a b16 or b18c head will outflow an LS head, period, sorry for not being so clear on that

and the reason my buddy said swap it or turbo it, is because he was turboing his car after doing all those mods and i asked him to reflect, and he said "i wish i would hvae gone turbo or swapped it right away" NA LS just isnt worth it, he said ultimately if you have an LS and dont want to swap it, turbo it" much less money for much more power

and i agree, LS motors respond GREAT to boost, but some people who dont know what their doing are afraid of turboing, and blowing up their motor, which most times is a result of the lack of knowledge of turbo systems and how they work, or not getting the setup tuned. which is true, i hear people all the time (people in my town LOVE to half *** things) say " im just gonna SLAP a turbo on my car and call it a day" you go ahead and do that, those are the people, and mindsets, that lead to blown motors, and then people hear about that and instantly think, my motor will only last 300 miles if i turbo it, look at what happened to "joes" motor, WRONG, its ALL in the tune and using quality parts, but it also help to have something other than a chimp install your turbo kit

enough with the rant, if you have an LS motor in decent shape, the best way to get the most bang for your buck, or HP for your buck, is to go turbo. no disputing that. But keep in mind, read up and know your stuff before your try to "slap" a turbo on your car

dayvid05:
i am more or less just lazy and dont feel like responding to all your points, because i agree with most of them, you make good points, im just too lazy to explain what im thinking in the first place

1994-2001 integra 2 door manual transmission

RS: 2529 lbs (1147 kg)
LS: 2643 lbs (1199 kg)
GS-R: 2667 lbs (1210 kg)

1994-2001 integra 4 door manual transmission

RS: 2628 lbs (1192 kg)
LS: 2738 lbs (1242 kg)
GS-R: 2765 lbs (1254 kg)

integra type r

2639 lbs (1197 kg)

http://www.itrsport.com/specifications.html

1999-2000 civic si weights spec

2615 lbs

so so even if the 94-2001 integra did not come with a b16 it would not make such drastic diference as we all would think.

Because it is faster then an integra with an LS.

O'really? Why don't you back your opinion up with some logic or explanation? I assume you're no longer in grade school. Wait let me guess? Because the B16 has Vtaaaaak right? LOL.

You sir are a [freak]ing idiot. All you need to do is think about if for all of 2 seconds. Which car is faster? A civic SI (B16) or a Integra LS (B18A/B)? Yes, the civic SI is a faster car and they weigh very very close to the same. So therefore the motor swap of a B16 into an Integra would make it faster.

Actually a LS vs '99-00 Si is a good race but the Si should pull in the higher end because of its gearing whereas the LS has a looooong 3rd gear. Put both cars with the same gearing and youll see the difference. Ive beaten Si's a lot worst than some LS's but than again there are several different factors that could have occurred.

LOL. Was that so hard to explain or did it make your brain swell?

posHonda: You are correct in that sense also. The only reason why the LS feels so sluggish is because of the lazy gearing. Give the LS motor the same tranny as the B16 motor and it will be a different result.
