So the b18c produces roughly 160hp and 111 ft/lbs of torque, the b18b produces 145 hp and what like 137 ft/lbs of torque. So, in a CRX which one would do better in 0-60 and 1/4 mile times? I see the b18b getting better track times and 0-60 times, but the b18c has more hp. Is the b18b better becuase of the torque? And in the end, does it end up being faster than the b18c up until the high speeds? Any help would be appreciated.

 

A B16a produces 160hp and 111 ft/lbs of torque. A B18c (GSR) produces a 180hp and 126 ft/lbs of torque. A B18c (type R) produces 200hp and 134 ft/lbs of torque. A B18b produces 145 hp and 127 ft/lbs of torque. There are other things though contribute to a good 60ft time or 1/4 mile time than just the motor that's in the car. There are alot of other variables that have to be considered.

 

where did u get the figures from, i havent seen # like that so let me know what were ur sources,
thnx

I go with the B18c with a nice tranny like a 96 spec type R, or a sc4 with GSr 4th and 5th w/ an R final

 

I got the numbers off of http://www.hmotorsonline.com they are all for JDM motors

 

Yeah, I got mine from hmotorsonline as well. I'm dropping a b16a into a crx, and I've been kinda worried that it may not be that fast or that torquey. I know the b18c would be better, but I can only afford the b16.

 

wtf?

 

That's why I was getting the numbers for the engines. I was verifying the numbers and then i was asking if you guys thought that it would pull very much in the crx.

 

my b16 feels slow now. I can't wait to put my frankenstein in.

 

The b16 with more horsepower will be faster than the b18b. I'm not sure about 0-60 or ETs, but the speed at the end of a quarter will be higher.

A motor with more power but less torque should theoretically be faster because it's the torque at the wheels that counts, and with a proper transmission more power = more torque at the wheels.

The higher b18b torque might help you out when launching, driving in traffic, or when you're too lazy to shift.....or when somebody really dropped the ball on their gearing selection.

BTW dude throughout your posts you're referring to a bunch of different motors when in actuality you're talking about other motors and it seems like you swapped some of their specs, too. You might want to clean that up...

 

Yeah, I've noticed that some to. I just started researching the engines and specs and I apologize if I'm getting some things messed up. In the b16 is there anyway to increase the torque other than turboing it?

 

A lot of you are *somewhat* correct. It depends what you want as far as "fast" and what you want as far as "quick". An LS b18a/b are going to be torquey compared to the b16a no doubt. They are 1834cc where a b16 (and even a b18c) are both not true 1.6Ls or 1.8Ls respectively. It's going to accelerate better on the low end but drop off in the high end where a VTEC crossover would be nice. However a lot of acceleration vs. Top speed is all in the tranny.

I was always under the impression that a GSR was 170 hp (at the flywheel) but I guess I could be wrong since I don't deal with them much.

For the best of both worlds do what I did, LS/VTEC (or "Frankenstein" or "Hybrid" or whatever else people call them these days). 161 whp 125 ft/lb tq (Both at the wheels so you're going to be adding 15-20 after that in comparison to factory specs) With the only bolt on being a 2.5" exhaust and that's untuned btw using a PR3 (B16a ECU) with fuel pressure cranked to 60 psi (don't ask).

It's a sacrifice in reliability but if you build it "right" (not like me) you should be very pleased. This includes lots of safe guards like a good flowing vtec oil line, cleaning vtec solenoid filter often, running full synthetic oil after the first 500 miles, ARP rod bolts to support the high revs, and when not racing keeping the car out of VTEC and in as high gear (low RPM) as possible (I drive around neighboorhoods in fourth, and main roads in fifth already).

 

Well I am going to do a b18c swap into my CRX and I was thinking about doing a b16a swap before i found out that the b18c is rated at 170hp@ 7600rpm 129lb-ft @ 6200rpm. The b16a is rated at 160hp @ 6200rpm 111lb-ft @ 5500rpm. I also read that the '94 b18c was the strongest b-series motor produced ...that made up my mind quick. b16b??? b18b (LS) is rated at like 142hp @ 6300 127lb-ft @ 5000. Choosing a motor really depends on you...and MONEY!!! I plan to build my b18c before putting it in...I was seriously thinking about going all motor..?

 

The b18a/b LS motor is great for turbo although with PR3 (B16a) pistons like mine and a VTEC head it does definately boost the compression ratio up there, nice for NA. If you are not someone who knows what they are doing and has shops do stuff for you, then just go ahead and get a b16 or b18c... If you're confident in your mechanical skills LS/'VTEC or even the CRVtec (b20/VTEC) are great choices to make cheap power.

by the '2G JDM B16A,' are you really referring to the B16B, AKA CTR?

 

Man, so much confusion in this thread. People calling engines by the wrong codes, people confusing PS with HP, people with incorrect torque specs, and people who don't seem to understand that more horsepower = faster.

Let me start with that list, with correct specs and codes:

B16A, 1st-gen JDM - 158 hp, 112 lb-ft
B16A, 2nd-gen JDM - 168 hp, 116 lb-ft
B16A3/B16A2 - 160 hp, 111 lb-ft
B16B, JDM - 183 hp, 118 lb-ft
B17A1 - 160 hp, 117 lb-ft
B18A1, '90-91 - 130 hp, 121 lb-ft
B18A1, '92-93 - 140 hp, 121 lb-ft
B18B1, '94-95 - 142 hp, 127 lb-ft
B18B1, '96-01 - 140 hp, 124 lb-ft
B18C1 - 170 hp, 128 lb-ft
B18C, JDM - 178 hp, 129 lb-ft
B18C5 - 195 hp, 130 lb-ft
B18C, '96-spec Type-R JDM - 197 hp, 134 lb-ft
B18C, '98-spec Type-R JDM - 197 hp, 134 lb-ft

A B16A will be faster than a B18A/B with the same car, same mods and same driver - period. More horsepower = faster. However, the B18A/B will usually beat the B16A off the line, because more torque makes for an easier and quicker launch. After the launch when the cars start revving up through the gears, the B16A car will start pulling on the B18A/B car, making up the difference from the launch and then pulling ahead.

Edit: Correction of an error, I forgot to include the OBD-2 B18B1 when I was changing the list.

no, the 2G b16a was in the EG and rated at 170hp. it had a little bump in compression and more agressive cams over the 1st gen b16a.

The b16b was rated at about 185hp/?tq

edit: I didnt see the guy above added it already.

 

I understand that the b16 is faster, what I'm wondering now is how long it would take for the b16 to catch up to the b18? Assuming its the same car and stock except for the engines.....

How long do you think it would take for the b16 to catch back up to the b18?

It's hard to say because they're fairly close; driver skill plays a big role in a race like this. Many good drivers with B18A Civics have been able to beat B16A Civics simply because they know how to drive (plus the B18A/B is easier to nail a good launch with than the B16A). All things equal though, I'd say generally that you'd be caught up somewhere in 2nd gear, and you'd be pulling ahead all through 3rd gear.

Basically, I'd choose the B18A/B if you just use your car as a daily driver and occasional racer, and the B16A if you're really serious about performance. More torque makes for a more pleasant daily driver, but VTEC makes for a little bit faster car overall.

Or, if you're mechanically inclined, you could get a B18A now, and then build it up and add a VTEC head later on. A properly-built LS-VTEC setup would be significantly faster than any B16A.

 

I'd do it the other way around, I think it'd be cheaper and you'd have better parts (b16 swap followed by b18a later on)

 

Thanks guys! I've been debating whether or not I should get a B16 or B18, I don't have the money for a B18, but my friends have be yelling at me to get one. They have been saying that the b18 would dominate the b16, and I was getting really discouraged. Thanks for giving me this info, it answers all my questions and doubts.

A B18C (the expensive B18 with VTEC) would easily beat a B16A, but the B16A should be a little faster than the non-VTEC B18A or B18B.

 

okay... so how do i tell if my JDM B16A is 1st Gen or 2nd Gen?

all it says on the Block is 'B16A' below that it says '1201827'...
