what is better ls motor or b16

[somedude]

I am planning on making my stock dx civic hb a little quicker and more fun to drive I am debating on the ls integra motor or the b16 you should give me your input on the situation.

B16 all the way.

y not the ls?

I know it partically depends on what you plan to do with the motor, but I think you should go with an LS...I personaly have that swap myself, I love the LS. The B18B1 is a great combo. Here's why I say that would be my choice, I hope it helps some on why I like the engine. The LS is a great engine for Turbocharging. It has a very very solid bottom end. In many cases, an LS can be boosted to 12 psi without blowing the engine, whereas the B16, and most others can't go much past 8psi safly (Of course, if you fully build the engine it's a different matter). Also, the 1.8 liter LS has more Low end torque, much more, than the B16. In the end, there in no replacement for displacement, IMO. Turbocharging does help make up for less displacemnt, and the LS engine stock is much better suited for turbocharing than the B16 (again, it can hold more boost, plus more displacement). The LS also is 1824cc versus 1595cc of the B16. Also, the LS trannys longer gear ratio's are prefactly suited for Turbo apps. Although for all-motor apps, like the type-r enigne, a shorter gear ratio can be preferential, for turbo'd apps, the longer gear ratio's of the LS tranny are best. The longer gear ratio's spool up the turbo better. I realize that some people don't like the LS due to "lack of Vtec," but the LS being so well suited for turbocharging more than makes up for it. It you are diffenetly not going to turbocharge it, the B16 is not bad, but I still like the LS better. Like I said, I like the torque, especially for street driving. I hope I helped out some.

Not trying to start an arguement but your post is very one sided. First off a turbo was not even mentioned but you are right from a FI point of view. NA on the other hand, the B16 will come out on top. You say there is no replacement for displacement and I agree but not in the case of these two motors. In this case there is a replacement for displacement......VTEC, high compression, and a better flowing head. Sure, the LS's 1824 cc's and rod to stroke ratio give it more torque in the lower RPM's but were the B16 lacks in low end it makes up for in the high end, where the LS falls short. Overall I agree that the LS is good for a tuner with FI in mind but in this statement....................

I would beg to differ.

B16EJ1, I am not agruing here. I said that, "It you are diffenetly not going to turbocharge it, the B16 is not bad." That was my direct quote. I said that if you are not doing FI, the b16 is "not bad." By that I ment that if FI is not your thing, the B16 is a good choice. As with any motor, the correct motor depends on what you wanna do with it. My post was in response to YamahaYZFR6 saying "B16 all the way," and 92egBOI "asking y not the ls?" I was trying to tell him why I like the LS. That is why I didn't really go into depth about the B16, or other motors for that matter. I was telling him why I liked the LS over the B16, since he asked. I agree with you totally though, as my comment above shows. If you are building a motor that isn't FI, but is all-motor? Then the B16 is a good motor for sure. As I said, to start my post, I know it has partially to do with what you plan on doing to the motor. FI is my thing, so I like the LS. But if it's not his thing, The B16 is a great motor for an all-motor app. An all-motor LS/Vtec can rock too, but I won't reccomned that to anyone. A bad build of those is bad, lol. You are correct, that the higher compression and Vtec was used by honda in the B16 to help make up for the lesser displacement. And Honda did a darn good job (low end torque not-withstanding). I always beleive that low-end torque is important, since HP is roughly the following formula. It is alittle off I think, but I can't qiuet remember it rtight now. HP=Torque * rpm/5252. The B16 helps make up for less torque, when it comes to achiving final HP, by Vtec and higher RPM. It does in a lot of ways help make up for the less displacement, but on a hill, off a stoplight, the LS and it's superior low-end torque will make the difference. But in the end, it's all the route you go that should dictate the motor you get. FI, get an LS. All-Motor, get a B16, or if you want the best of both worlds, in terms of displacement (and more torque as a result) and VTec with high rpm's, then the GSR instead. All the formentioned motors are good, it just depends on what you plan on doing with them. Maybe in my last qoute you qouted me, it was comfusing because of the double negative in the sentence. That made it all confusing and such. If you take the time to break it down, it says the same thing you said, but written very poorly. What I should have wrote, however, was "if you are not going to turbocharge the LS, the B16 is a good motor instead." We both agree on the same thing, I just stated it very poorly in a grammatical sense.

I think that's what happened.

Why dont you use the ls bottom end and slap a b16 vtec head on it? ive heard that works real well

Ahh the good ol LS/Vtec it would be or Frankenstein motor what ever you want to call it. Its a very good motor, but unforunatley its also very hard to do properly you need to have a machine shop tap all the oil lines properly and such. Also the motor in general is umm the only word i can think to use is unstable the motor is unstable. But if it is done properly and everything it is one of the best motors out there IMO.
