2 things I wanted to say first. Why do I always see B18's getting stomped on by b16's ? Both built. And Don't just say one or the other, give a good reason. More hp, and more torque aren't always the answer. How much more does the B18 weigh. Power to Weight is the biggest factor in racing, Not Hp or Tq.

Ok I live in cali the best deals I can find so far are this...

For $900 I get a LS B18 non vtec, Ecu, Wiring harness, Driveshafts, and trans.
Or for $750 I get whats being said is a B16 that came stock in an Integra, and i get the entire car.

Now I may be wrong But the only Integra I know of is like the 86 but it has a DOHC D16, which is roughly 113 crank hp. I have a D15b7 with 106, it'd be stupid to pay 700 for 8 hp. Is there another integra?

I'm going to look at the B18 today. still trying to get to go see and verify the b16

So which is better if all is true.. I know most will say the 1.8l but why do so many b16's do better?

 

The weight difference between a B16 and a B18C is sooooo minimal that too actually think the power to weight difference, in the engine alone, will make a difference is ridiculous.

The other factors are gearing ratio (B16 trans vs. LS trans and FDs also), driver, shell (VX hatch vs. Integra sedan), mods.

Theres so many scenarios, you can't justify your claim that B18s are getting "stomped" on by B16s.

This thread is a cow's opinion

one of these days i am going to take the torque curve of the b16 with the b16 tranny and the b18b and b18c with a couple of b trannies to show how the torque curve looks through the gears...

anyway, i feel the b16 has 2 redeeming features: the head and the gear ratios.

 

A b16 from an integra? i don't think so..... i might be wrong but the only integras i know of have b18b non vtec, b18c vtec, and b17 (non vtec)

as far as your question goes. the b16 you're talking about has a higher compression and higher top end power than the b18b does.

there was an article on this forum about the b16 having better head flow than the any b18, so that would have something to do with it as well.

 

B17 is DOHC VTEC.

is it really? that's one thing i'm not sure of lol

 

Came in the 92-93 Integra GS-R, it's first dual cam VTEC.

In the US that is.

 

Well the only teg i know that comes stock with a b16 is the jdm DA tegs XSi and RSi.

Yes 100% correct. I definetly was not crystal clear.

I know someone in the So Cal Marketplace selling a 94 B18b1 swap for $725 OBO and you get to test drive it...

I will always argue anyone that stock vs. stock a B16A swap will outrun a B18A/B swap if both are in the same weight chassis.

The B16A has more power, a higher redline, and most importantly, closer gearing to match with the higher redline. The extra revs and better gearing are better than the extra torque that the B18A/B have.

I work at a shop that has done a lot of B16A, B18A/B, and B20 swaps into various Civics, and I've never seen a stock vs. stock B16A lose to a B18A/B swap in a dragrace - ever. Others will chime in with "yeah but add cams" or "yeah but throw a B16a or ITR tranny on that LS swap y0!" but I'm talking stock vs. stock.

Not a bad deal I suppose, but a few keys are:

1. Mileage?

2. What year/make/model car is it comin from?

As others have clarified in Japan there was a DA chassis Integra XS-i that came stock with a B16A. It was an OBD1 engine with a cable tranny.

The Integra you'e thinking of would be the flip-up headlight style 86-89 and yes it was a DOHC non-VTEC 1.6L engine called the D16A1 - bascially like a twin cam ZC engine. IMO 100% pointless to try and swap, ESPECIALLY depending on what car you drive - mounts and axles, etc. might not work at all.

Also because you're in Cali anything is posible I suppose. It could be a 1986 Integra that someone dropped a B16A into, or it could even be a DC 94-up Integra someone dropped a B16A into - I've seen strange combos before. These cars might not be "stock" any more.

Most important detail you've left out is what kind of car you have. That will determine which swap to get.

I assume it's a 92-00 Civic with this forum being the 92-00 forum, but let us know so we can better help you. In Cali you might even run into BAR/ref issues depending on what car you have and what engine you buy.

If that LS swap is a cable trann forget about it - same with the B16A if it turns out to be one.

We need more details you help you in this very speific circumstance.

 

I'd go with the b16 over a ls b18 motor if thats your two options.

 

My car is a frankienmobil, the motor is a D15B7, which would make my chasis a 92 civic dx hatchback. But the b18 turned out to be auto trans and the supposed b16 i can get a hold of the guy now to see it.

I've found I can get D15's for less the 3 bills. so i figured I'll just build my B7. I'd like to swap to a d16 vtec head. I've found it hard to find crakshafts and parts to build the bottom end though. I will boost at some time.

 

i got a jdm b16a long block for 500 or a different b16a that is complete changeover for 92-95 for 1500. or a jdm b20b longblock for 450. LMK. If i decided to stay single cam i would build a d16z6 on the side if you plan to boost later.

 

Id drop the b16 in an have some fun

To clarify, the engine does not make the chassis. Some chassis codes might be dependent on what engine came stock, but swapping an engine does not change the chassis code of the vehicle.

Technically, if you have enough power to overcome your weight, the P/W ratio becomes irrelevant to an extent.

That said, a more important factor in racing is the driver. Point in case, I've beaten a 97 Coupe with a B18A and B16 tranny with my car, a 2000 Si. Each were bone stock at the time. From a dig he would get the jump, from a roll I would. And I would barely pull on him. That's all driver skill.

Truth. It's essentially a slightly larger B16. B17 is 81 x 81.5 (bore x stroke) vs the B16's 81 x 77.4(bore x stroke) .
