any difference between B18b and B16a?

[tekung89]

soz for first post, ddnt meant that intentionally.

to sum it up in a nutt shell, my mate has a b18b and for some odd reason he has quite alot of power so i did a comparison between a b16a and a b18b and the b16a had i think about 10hp maybe less over the b18b engine

my idea is, would it be cheaper to go a b18b engine then do some light mods to gain more power to have more or the same power as the b16a and for future mods , u could always put a b18c head on the b18b block which will give u more power then the original b18c engine.

let me kno if this makes sense to your guys.

[dsp26]

how do u know he's 'got more power'? have u both dynoed?

answer is torque advantage

get the B18b to begin with... want vtec, put a b16a head on it... i've seen a few go cheap in the FS section

[tekung89]

yeh thats the problem i cant post how he found out he got more power lol or else this thread will be deleted. yeh i think we're too worried about hp and not looking at the torque.
i was jus thinkin it could be a money saving thing to go b18b first then vtec it later =) ddnt mean any disrespect to anyones engine

[bennjamin]

ok -

b18b has 108kw and 172NM @ 5000rpm
b16a has 118kw and 151NM @ 7000rpm

The b18b is a better everyday driver car with more useable power
The b16a2 has better top end and in a lighter car will be faster

[hondavti25]

A freind of mine is thinking of doing a b18b with B16a head should be good to see? any one know of what kinda of power out put or results this would have? is it expensive? ie cheaper then a b18c conversion and more effiecient

[aaronng]

Don't think a b18b/b16a would be that much cheaper than just getting an audm b18c

[z3lda]

The b16a2 has better top end and in a lighter car will be faster

that can be said for the b18b aswell

[BlitZ]

B18b will be on par with a b16a in an ek weighted car... maybe not top end though

[SLOWEGG]

B16A also has better gearing.

[dudeling7]

yeh the gearing of the b16a is much better.

i think i great mod for the b18b would be in the gearing, getting a better final drive.

I have a B18B and to be honest its not the fasting thing out there but its great for what it is with minimal bolt on mods. ive easily beat b16as off a roll at the track ofcourse.

a b18b in a light car like a eg or civic should go pretty well for the price.

[TECBOY]

u will find that u will thrash the b16 to get decent power out of it. The b18b has more even power curve = better for usuable power and daily driving

[EKVTIR-T]

Using a higher final drive with B18A/B will not suit it's powerband.
They don't make power up high so pretty pointless.

How can you say the B18b will have better topend "aswell"?

[dudeling7]

it does still help though. in the states many people add gsr or b16 gearboxes and can get their b18b's into the 14's with them.

usually if im fanging it to redline changing 1st - 2nd it will land around jsut over 4000rpm which is very low. by adding a better geared box you can land a little higher maybe around 5000 where there is more power and torque.

If you wanna try using the 4.4 final drive then be my guest.
Our engines are not designed for topend high revs but it's up to you mate.

[dudeling7]

haha ok, do you have a GB i could use? so u are certain it would make absolutely zero difference? i really highly doubt it would make a difference, then whats the point of changing a final drive on a car in the first place? i would think its a good mod to improve overall acceleration.

a b18b gearbox has pretty damn long gears being a 4.2 FD ofcourse changin it to a 4.4 or 4.7 will improve acceleration but drop top speed. so it would be a bitch to drive on the highway. but im sure 1/4 mile times will be reduced.

many people have noted that their 1/4 mile times have dropped .2 - .3 secs due to this change in gear ratios, and although it may not be mot suitable for the daily driver due to many gearchanges and higher reving constantly, it should help with acceleration.

Hes saying that if you put a b18b in a lighter car, the car will be faster as well...similar to putting a b16 in a lighter car.

Umm thanks.It's natural that using the b18b would make an eg faster.
Although the cars would drive differently.One having nice low/midrange and the other being revvier and with great topend power.

[bennjamin]

are you sure about that ? i have seen egs either both the B16a2 and the B18b.
The eg with a B16a was "quicker" in all instances

[EKVTIR-T]

If you read Qballs reply properly,it says [as well].
As in I meant using the b18b or b16a would both obviously make an eg faster.
I was just saying the b18b would drive different to the b16 thats all...

[Limbo]

in the states most people with a b18b do a LS vtec conversion. They have kits for this and especially when b16 heads are cheap a cheap conversion.
Apparently the b18b has a slightly larger bore stroke to the b18c so makes slightly more power than your b18c.

yes and if you read my reply it is relevant to your post too. A EG with a b16a2 will be faster than a EG with a b18b. Only difference is , the b18b will be more "driveable" day to day with short shifting etc as its got more poke (torque)

[tekung89]

how bout in terms of cost?, price ranges of a b16a motor range from 2000-3000? i 'heard' the b18b were relatively cheap, around the 1000-1500 mark

if this is true, than it would take only little bolt ons for the b18b to be running as fast or faster than the b16a, while the price still remains under the price u would pay for a b16 motor :P unless people have connections

[REVteg]

difference is... 1 is vtec and the other 1 isnt..

vtec opens alot of doors.. dont worry about the b18b. go the b16a..
if u go b18b u mite as well go for b20b

[ZeForce]

if u go b18b u mite as well go for b20b

Thats a good point and a non-VTEC B20b > B16a

[BlitZ]

I highly doubt the same would apply to EK where torque is required.
I reckon they would be fairly close...

however cost wise.. by the time u get all the b18b peripherals (driveshafts, etc etc) the cost would be very similiar. vtec would also be 100 times more fun as it loved to rev

[z3lda]

the cost of installing a b18b will always be a few grand cheaper than the b16a. even with all that hidden cost.

[dc2dc2dc2]

b16a is the most overated engine ever.

[aaronng]

So you prefer the 94kW/182Nm B20B over a 106kW/175Nm B18B? I'd rather give up that 7Nm peak torque and gain a higher proportion of torque at the upper end.

[REVteg]

yeah id still go for b20b.. when you do mods theres much more power to be gained out of a 2ltr then a 1.8lt.. same situation as 1.8 over the 1.6

so when you vtec the 2ltr it will be alot better then the 1.8

The liners in a B20B is thinner than the B18B by a significant margin. The rods are weak and the compression is low. So if you were thinking about raising the rev limit, you had better factor in a rod and piston upgrade, as well as possibly block posting. In contrast, you don't need to add vtec to the 1.8, you just buy a B18C7 in the first place.

[REVteg]

yeah add in arp heads and studs. simple. build it right and it will be good. it wont cost that much to change a few parts

b18c7 yeah go for it.. it costs alot to buy just the engine. without installing it. b20vtec will be cheaper overall to install as well.

[90LAN]

its funny that b18b's sit in the wrecking yards and never get sold and b16a's go like hotcakes .....
anyway why would u want the hassle of installing a b18b for a little bit of torque when the extra outlay of installation in a eg would cost more than a b16a swap
go for the b16 some thing that has been tried and tried again to be the best bang for buck conversion for the eg
any of the doubters of the b16 out there done a b18b coversion into a eg
had the car dynoed? drag times ?......i didnt think so
becos it would be a waste of time and effort for such a bullsh#t return
anyway my 2cents from my experiences .....

[tekung89]

b16a is the most overated engine ever.
i agree, i think people forget that engines do lose their power, with the b16 being a vtec, it is only natural for the engine to be thrashed, thus getting more worn out. and i hope we're all talking about the au b16's not the jap specs lol
to me, REVteg's idea in terms of bigger engine size for more power seems pretty tru. eg is the b16a vs the b18c =) big difference there. jus imagine b20 vtec =D. but for less hassle, mann.... jus F*cking drop a k20 in lol

i thought this tread was about a b18b compared to a b16a
funny how things change ......
any way go spend your money on what ever u think is the best engine setup for your car is !!!!
and let us know what power specs and times u get for the amount of money u spend !!!! and if it was worth the money u spend and hassles ...

[90LAN]

b16a is the most overated engine ever.

it was the best overated engine in the 90's
must be hard to hear how good it is over and over again
for such a small engine ......

[REVteg]

yes it is about b18b compared to b16.. but its a forum where people discuss and throw other points in to come to a conclusion..
so if you say ur thinnkin about the b18b .. n some1 elses suggest y not b20b because MAYB they didnt think of it in the 1st place

[nigs]

I reckon, go with the SR20.
They're worth a mint, a week before RACE WARS!

becos he is asked about two engines that are budget builds not other builds he has to spend 5k plus for the set up .......

[REVteg]

well if your going to mod the b18b you might as well mod the b20b.. thats what im saying..
b16a uor gona spend 4k.. might as well go b20vtec

[tekung89]

nah i started this thread out of interest , but yeh , things got carried away with peoples different perspectives ay, haha its like a war here. i thought i'd jus break the ice with the whole 'go K20 for simplicity sake' lol chill out guys

[z3lda]

how can u say that installing a b18b into an EG will cost more than a b16a?

when was the last time you bought a b18b and a b16a with box/loom and ecu?

i can pick up complete b18b conversion kit for roughly 1k. inc.s engine/box/loom and ecu

where as a complete conversion kit with for the b16a will cost roughly 3k

installation will be exactly the same as both are b-series and both will require teh same parts.

thats already a saving of 2k even after installation.

[dudeling7]

^^ lol thats what i thought too. B18B's you can get really cheap for the whole package. a lot less that a b16a installed. as its a b series engine the same thing will apply with engine mounts etc. but the price of the engine itself with the gearbox, B18B way less than B16a.

in the end either one will be good in an EG. it jsut depends on your goals and what you want to do with the car.

[90LAN]

lol good on ya then what a bargain !!!!
wonder why people dont go and do b18b conversions ???
u must of got a mint motor for that price ....

[dc2dc2dc2]

reason why people don't go for B18B is because they just wanna say 'i have vtec y0'

[90LAN]

reason why people don't go for B18B is because they just wanna say 'i have vtec y0'

why say "vtec yo" when u can HEAR IT ......... if u have a b16a
better a farty cannon muffler sound coming of a b18b!!!!!
lol....

[EK1.6LCIV]

I've seen some very nice b18b installs back in the states, heaps of potential. At one stage I was looking to go for one in my EJ8.

[barefootbonzai]

If someone can point me to a complete b18b conversion for $1k please let me know...

[yah mum]

i did it :D abit over 1k tho!!!

[barefootbonzai]

i did it :D abit over 1k tho!!!

that's cause i hooked you up with cheap parts lol.

[z3lda]

If someone can point me to a complete b18b conversion for $1k please let me know...

last time i checked around with melbourne wreckers, complete b18b conversions were about 900-1000$

max would be 1500$

[yah mum]

thanks to dee!!
