Comparing boosted D16Y8 and boosted B18C1
I am guessing that a built B18c1 will produce more power against a built D16y8. Both turbo charged of course.
Please let me know if i'm correct or incorrect.
Also, please don't consider the price of the engines. Just imagine that you own both of them already.
I have seen some build D series motors produce pretty close to 400whp without sleeving. Could someone please let me know what kind of numbers to except from a boosted and well tunned B18C1.
Thanks in advance.

Im guessing that the b18c will make a tiny bit more power...just a hunch though 
. And who do you know thats making 400hp on stock sleeves in a d series? Im not saying that it CANT be done...but im calling bs until i see some pics and charts. I have seen some amazing things in here though...mainly thanks to the tuning genious known simply as...st00pid

I had the same hunch too 
AR Fab at
ARfabrication.com says that the shop got a SOHC 395whp and 370fttq.
But i was just trying to mainily see what kind of numbers to excpet from the B18C1

Re: (RNPoo7)
well just because a motor made xxxhp/xxxtq doesn't mean another motor can't make more now can it? and to answer your question. a D-series vs a B-series with the same mods... the b-series will make more power period

Re: Comparing boosted D16Y8 and boosted B18C1 (RNPoo7)
are you trying to be funny, or are you seriously lost on this one. What on earth would make you think a d16y8 turbo could possibly compare to a fully built b18c1??

Re: Comparing boosted D16Y8 and boosted B18C1 (iwhichisme)
No I wasn't being funny. I was just doing a lot of research lately, and I just wanted to make sure that it would be worth to get a B18C1 over my D16.
I know that it would make more power, but i trying to decide if the B18 is worth the money i spend , that's all.

Re: Comparing boosted D16Y8 and boosted B18C1 (chidoks)
now being the owner of a boosted B18C, I would have rather kept the D in my civic and built the **** out of that for my daily driver. I would have spent less on same level of horespower that I want to get to.
Of course B would get higher levels of power but again FOR ME, it would have cost less to get to the same horespower I want out of the D than the B.

All things can't be equal though, the B has one cam too many.
The main reason the B18C1 will make more power with the same turbo setup as a D16Y8 is the added .2 liter displacement.

The main reason why the B series make more power is the R/S ratio and Bore size...in other words...displacement.
Add a nice flowing VTEC head on the combination, and theirs no beating it in the realm of the Hondas.

Re: (Bryson)
Ok, so now we know that the B is going to make more power than the D.....I assume the B would be more reliable than the D also...right? Able to handle more power daily (even though they would both be built)?

don't forget about the head for sure. the head is DEFINITELY better than our D's

Re: Comparing boosted D16Y8 and boosted B18C1 (CivicRyda2k)
My buddy made like 350whp stock sleeves D series. He is shooting for 450 with his sc61...and with the tuner we have I think it more than feasible..

I'm sure the B is more reliable for a daily driver. Just wanted some reassurance on that.
Is the D series much cheaper to build over the B ?

Also, i see that you have made 390hp on your GSR. What's your setup if you don't mind.

If i was driving a daily driven Civic, i would do a mini-me. and turbo that. no reason to swap the B series in. The thing that really makes the D series weak are the stock rods. replace those and one of the big limiting factors is gone. then you are free to get up to over 200whp.
