Lookin to do swap, Better engine?

Now I was told b16s are slow compaired to ls's. I only think its USDM b16s though because the JDM b16 puts out torque 1200 rpms sooner then the USDM ones. I would love to have a b16 for its revvability, VTEC and reliability. But I heard LS is just a straight up fast motor. I would like to know the opinion or outcome on other peoples swaps they have done... Like is a b16 faster. Well to be exact a b16a2 it has like 170bhp 113lbtq then a b18 (gs,rs,ls) with 140bhp and like 121lbtq. I was told b16s will run like low15s but an b18 will run mid-low 14s. Can someone clarify this for me?

well if you get the more common b16a and the b18b mounted side to side in identical cars, they will prolly run a pretty even match. however most people would go for more displacement up top first, then swap the b18 head for a VTEC head from the b16.

But I heard doing that makes like a frankenstein engine. Its not totally reliable and its an oil burner. Its taking a low rev block and a high rev head and putting them together.

What about an H22. It will be sick fast. I wanna kno bout the steering issues. Plus I wanna kno what 1/4 mile times I should be expecting with all 3 ls, b16a2 and h22

this thread is full of almost every freakin misconception in honda motoring. first of all, a b16 and an ls motor in identical cars that are racing eachother will not be equal. the b16 will most definitely win assuming the drivers are equal. the extra hp will pull the b16 powered car by easily. the third gear in b16's will whoop on ls motors like nothing, i know because ive seen it time and time again, not to mention it has 20-30 more hp than the ls motor depending on which b16 you get. also a b16a2 does not have 170hp. a b16a2 is out of the usdm 99-00 civic Si and has 160hp. the jdm ones are merely b16a. and i dont know who told you ls motors will make you run 14's and b16 will run 15's, thats a complete bunch of bs, b16's are faster no matter what.

about lsvtec, this has been covered like 5000 times on these boards. lsvtec is not unreliable and does not burn any more oil than any other honda motor. you do know vtec motors always burn oil right? its morons who dont know what theyre doing that make lsvtec motors seem like a bad idea. if you know anything at all you can make an lsvtec correctly and it will be just as good as any other honda motor. but there are rules you have to follow. i wont go into them unless you want me to, but they are very simple.

and yes the h22 will undoubtedly be faster than your other choices. but it is a more expensive swap, and will throw off your steering to some extent. it will make the car more nose heavy than it was before causing understeer. i say stay away from h22 swap unless you are going for an all out drag motor.

hope i helped you out and this was not an attack by any means. just hate hearing these misconceptions over and over because then it spreads like disease.

oh yah and the times you might run are dependent on way too many factors to give times. lets just say that lies in how good of a driver you are.

I definitely agree with edman24. B16 are much better at top end.

i dont care what b series motor you decide to use. it all depends on how you go at it.

please someone with a b16 pull on me please oh please

hasent been done yet...im still waiting....

how bout a boosted b16 ;)

specs to specs with different motors, the specs speak for themselves. All B series motors are good bases to work with. Get what you can afford...........and start from there.

If only i still had my rex....well when i had the b16 in it at the time.

All that you just Said Edman made total sense. I just made this post so I can figure what I kno compaired to my friends.. I consider I kno a lot but everyone doubts me and tells me I am wrong. Although Idk if you said it was wrong an LS will run 14 with a good driver when put in a civic 4door. (My friend Joe intake, header, exhaust, chipped ECU) So I could believe it would be faster in a Hatch. And I apologize I meant b16a1 outta the JDM sir that puts out torque at 5600 rpm instead of USDM 7000 rpm. If anyone else has an opinion for me to hear post it up.

im sorry does this mean you have an ls motor and noone has beat you with a b16? give me a hatch like yours with a b16 and equal mods and i guarantee id whoop you by third gear. im not talking smack but obviously anyone you have raced could not drive as well as you do. a b16 is faster no matter how you look at it. the ls will get the jump but by third gear CONSISTENTLY the b16 will be faster.

Yes I have an Ls motor, I have a crx not a hatch.

I, me, myself have pulled dozen's of b16 car's from roll's and stop's. from a roll lets say 2nd gear I have instant power and I start to pull immediately by the time 3rd and 4th gear roll around they are so far behind they cant catch up and vtec will not help them. from a stop same thing I just pull on them 1st 2nd and keep going.

I have a ls in a 91 crx si that weighs more than stock considering im a big guy 250lb's and the heavier motor/tranny/brakes. I have run a best of 14.7 @ 92mph with a broken motor mount, factory michellin tires yes factory, and a ebay short ram and a thermal catback. with the fixed motor mount alone I could probably see 14.5's.

There was this one race of evenly matched car's this kid had a 91 b16 crx si i/h/e vtec controller he thinks hes the hott shit so we go from a 2nd gear roll I jump it alittle to provoke him to start so he gets the jump on me by the time he was a fender up I stomped it and instantly pulled him a car in 2nd shifted to 3rd kept pulling hard got in 4th and just shut it down with him 3 car's back.

maybe you guys are just racing kids with ls swaps with the shitty ls tranny. b16a vs b18a same tranny same car that weighs equal and I say the ls comes out on top. I mean I dont know how I can race atleast 12 people with a b16 and not a single one of them can drive.

im glad youre doind so well with the ls but i will disagree with you. it is very possible all 12 of them dont know how to drive. you have to understand that although you have more torque at a lower rpm that becomes negligible by third gear. ive seen races and actually taken part in ones that include cars with almost identical weight and mods, one an ls the other a b16. the LS got off the line quicker everytime but third gear was no match because the b16 has more hp no matter how you look at it. the ls; power drops off after about 5000rpm. the vtec in the b16 allows the power to continue to climb until the preset redline which is why it should pull past you on the top end.

oh yah and we were talking cars that have complete ls motors. that includes the tranny. i assume you have a gsr or b16 tranny? that changes a whole lot, but the b16 should still be faster.

hmmm i dunno....

I'm not sayin i'm the best driver but i did drive my stock b16 at a track and hit 14.8 which is not bad. LS sucks at top end and thats the disadvantage. I dont care how many b16s u raced. Obviously they can't drive. And i'm glad you picked a crx cuz hatchies are ugly lol ;)

well what year and model was your crx.

like you cant compare a 88 hf to a 91 si with the same motor the hf will be quicker hands down.

If you're talkin to me i had a 90 crx si.

I mean im talkin weight here. My car probably weighs in at around 2,400+ with me in it

What year Ls are you carrying? What mods do you have since no b16s can keep up? I really wanna b16 but i would have to order from the internet and idk how long it takes. So I might end up pickin up an LS from a salvage yard. So If anyone knows bout ordering a swap off the net, drop me some info as to if its worth it or not.

www.hmotorsonline.com I hear they have good service and i think you should be getting the motor in one week or less?

b18a block b18b head, ys1 tranny, ebay short ram ebay filter, thermal cat back....simple

also I think I can drive my car very well.

i ran low 17s on my stock civic dx hatch. with just catback n ram air ractive filter. So I think I did pretty good.

I have to agree with edman24. From what you post, your know your engines man. People who has done ls/vtec 's out that messed up; makes it look bad for everyone. If you put an LS vtec into your car man make sure you hook up your knock sensor. Thats one thing alot of people dont do. I always hook every sensor up and try to leave the motor the way it came from honda. My daily driven B20 Vtec runs 13.3 all motor on a stock block.

About the whole b16a talk. Just add jdm type r headers, manifold, throttle body, and a chip gs-r ecu. You should be fine for daily driven. Dont listen too much about what others post. Most of the things posted on this site is BS.

h22 will go 13 sec in a 4 door civic with small tires. In a 2r with big tires is fast

Dont listen too much about what others post.

Dont worry I dont.....
