B18B a swap or NOT?

[SIvic]

I have been pondering the decision of swapping my sohc ZC over to DOHC ZC, or going with a B18B swap.

I am very familiar with both swaps, pricing, and parts needed..

but I wonder, honestly is the torque of the b18b really beat a ZC in a quarter mile if geared properly??


does anyone have quarter mile times of a b18B, or A1 stock without TURBO?


thankyou for any input......

you are looking at 10 more horsepower and enough torque to toast a ZC. This all goes back to the B vs D arguement which never ends, but if i were you i would go with an LS (b18a/b) simply for the fact that it has more torque than any other B series (with exeption of b20b/z)

torque wins races, horsepower sells cars, and in this case, you are sold and you have won the race.

I did 14.7 @ 89 mph on my 97 LS b18b. ITR header, HKS exhaust, lightened flywheel...stock clutch, street tires (Nitto). Full interior, 88 civic hatch (DX)

91civicDxdude, I understand the difference in torque....BUT....what about the revability.......from what I understand a b18b will not rev past 6700 or so.... where I can get a zc to run about 7200-7500....that will keep me high and ready to bang off another gear!


my sohc ZC beats stock b16a in crx/hatchies


current mods:
sohc ZC
mild ported/polished head
exhaust
cai
pr4 ecu



down the Quarter MILE what will come out first saying all is stock, same driver,


B18B
ZC (DOHC)
B16A

Not bad... I have seen timeslips of a gutted Crx with slicks that runs LOW 14's (The one he showed me was 14.2) with only headers intake and exaust and camshafts... Sooo thats when i decided ZC for me

Out of those choices... In a 4th gen? B16A... Why? Because our cars arent heavy they are light. We need HP more than TQ... Of course its nice to have an assload of tq as well, but stock b16 wins, then the b18 and ZC are Verry close. Within half a second stock.

[SIvic]

honestly what I am really looking for is a VERY QUICK, light to light motor.......



the b16 is a torqueless shit....I beat them badly!!!
i dont know if its bad drivers but I roasted them all last summer....

[seth 90DX/ZC]

Bad drivers... I seen em run LOW 14's to mid 13's... Mid 13's with I/H/E for sure I am tellin you you should go with the ZC OR fuck it! That Z6 you got is an awsome little motor! Turbo/Supercharge/Nos+internals tha bitch and dont even trip on any of this BS... I meen your already smokin B16's right? So its gotta be somewhat built, so finish you project and quit makin me type....Ima get carpal tunel, fucker...

go with the b18b. i did in my dx. they have a distinkt soud. plus they have plenty of tourqe for daily driving. You need tourque just as much as you need hp . cause it gets you up to speed . if your car will do say 200mph top end you need tourque to get you their faster. And for revability you dont need it to turn up cause it is a tourque motor. But you can get chips to raise rev but with the b18b you have a rod/stroke ratio that if the engine turns up to fast it will wear out your cylinder wall faster. Although you can put some block sleeves in and you will be fine but sleeves cost $500. My friend had a b18b in his 6th gen hatch and ran 15.1 on drag radials with intake & exhaust. the b18b has more tourqe than the zc and about the same hp ------------b18 all the way

if you have the funds then go with the b18. They are great motors to turbo or you can go ls/vtec or whatever road u chose. A zc is nice because it is cheap and u dont need mounts. I think there are way too many b16s out there so try somethin different. Go b18 if u can...u will enjoy it.

[mellowboy]

Go with the ls motor. U seriously beat a b16 4th gens with your sohc zc? Even though they're torqueless they rip on high end! ZC is also torqueless. The most torque of stock honda motors is the gsr/type r motors. 134 lbs of tq. I know b16 aren't torquey at all thats why i'm swappin the short block out for a gsr or type r if i can find any.

Well you gotta understand that ls motors are not high revving motors. Notice that them muscle cars have low redline. Those are torque monsters! Torque wins race buddy

[Jmunk]

Go with the B18a not the B18b, it's more work with the b18b due to the wiring.

[redmanjd]

b18a and b18b are the same motor. the only diffrence is cams and map sensor . you just use a b18b map. and you have more hp over th b18a.

[civickiller]

i think he talking about obd0 is easier to wire than obd1 because the 90-91 b18a is 0bd0, the 92 - 93 b18a is obd and b18b is obd1
