I would definately disagree with you over the highway pull....my buddy has a GSR with CTR intake cam and i/h/e chipped. I had the Greddy kit on my y8 for a long time. Both of our cars run like shit but boost+bad rings=worse than what he had. Anyway, from 80-120 he couldn't touch me....only reason he was able to keep up was cause of my longer gears. Don't get me wrong a lightly modded type r swap or even gsr swap is nice but god I love boost. https://honda-tech.com/forums/images...s/emsmilep.gif Take away my first and second gear I don't care ^_^ lol...when you can go 14.1@100 mph in a 2600 lb car w/driver on 8 psi....that's not bad.</TD></TR></TABLE>

So why is it that my 176whp B18C5 stayed almost dead even with a boosted B18B hatchback (Shawn from AL) on a few highway pulls on our way to the H-T ATL meet? I believe he was on 8psi or so, and his car runs great from what I understand.

If the only thing you're concerned with is highway then good for you - I'd rather have everything else and be a bit behind on a highway pull.

Gearing is where the DOHC has the advantage - period.

I don't know the factors or what your friend has done but look at it this way...an LS boosted with a decently sized turbo on 8 psi should yield over 220 whp. And roughly in the 150-160 tq range would be my guess...I'm not sure though. SO he would have more hp and more tq than you...how you kept up I don't know https://honda-tech.com/forums/images...s/emsmilep.gif Toms got the magic hatch ^_^

Re: Turbo SOHC or All motor DOHC....my conclusion (Mr. Teal)
 

DOHC please and thanks!

Re: Turbo SOHC or All motor DOHC....my conclusion (B_Something)
 

get what you can afford........and be happy with that

my opinion.

both motors are capable of making BIG power, however, all things being equal (modwise+tuning) the DOHC will make more power and last longer.

if you have the $, then go big. if not, the D series is nothing to sneeze at, it has lots of potential, but may eventually cost more to catch up to the bigger B series.

i would argue that if you spent another 3-4k on thr gsr then you would be making an even comparison to your last example of an aahhhhnold style sohc turbo many tuners right now are pulling quicker 1320 times in na bseries than turbo d series you just need traction https://honda-tech.com/forums/images/smilies/emthup.gif

I would still take the all mota over a d series after reading this.

Re: Turbo SOHC or All motor DOHC....my conclusion (b18bme)
 

Is it cheaper to buy a type r motor with r tranny... or a b18c1 short block with b16 head or type R head with b16 tranny? Which head would put out more power? I'm looking to have a all motor set up.. otherwise I'd jus get a complete gsr swap. Probably going to buy a old civic hatch to put it in.

Re: (Turbo E 604)
 

BTW:

A friend of mine has a B16A block making 193whp and 128ish torque to the wheels - N/A.

It wasn't rocket science - Alaniz headwork, good cams, 84mm bore with Ge sleeves and 11.5:1CR and Hondata tuning.

...and remember, the B16a motors are going for CHEAP unlike the B18C1/5 which still command premiums.

Some of the tasks are still not reachable for most of us. If the sky rains money, wouldn't that be a pretty sight?

Seen the car, very impressive.

Also, b16 with the price it is, allows you to put alot more back into the motor. Alanez?

it still seems that sohc turbo is pretty cost efficient for people on a budget. Im gonna start lookin this week for one to piece together for my d16y8.

and then be maxed out on the SOHC, and need to do at least some of the internals if you want more out of the "SOHC screamer"... do it right... DOHC. and if you're stuck on FI, turbo the DOHC... that's my story and i'm stickin to it. https://honda-tech.com/forums/images/smilies/emthup.gif </TD></TR></TABLE>

maxed out? stock SOHC's can easilly make over 200whp if they're tuned properly. not to mention the fact that you'll be making more torque than almost any built B-series. my friends 2.0L built ITR made 158lb/ft, which was about 20lb/ft less than my old stock engine D16Y7 turbo, and he only made about 15 more hp at the wheels.

i have to say though, between the choices of N/A DOHC and SOHC turbo, i'll take a B18C1 turbo.

all i'm sayin is no matter what ANYONE says, DOHC will always have more potential then SOHC... doesn't take a rocket scientist to figure that out. either way its going to cost a good amount of money.

for whoever said my head was far up my ass... tell me i'm wrong. SOHC has potential, but not as much as DOHC, you can't argue that.

theres no doubt about it. you can make 260+whp on a DOHC motor with the same displacement and same ammount of boost as an SOHC that's only making 180. but for people who are on a budget (like myself) and want a relatively quick car, SOHC's the way to go.

Re: Turbo SOHC or All motor DOHC....my conclusion (Mar_EK)
 

Well "Mr. Teal" is definately on a low budjet.....all I can say is that he needs to save his money for something better (like college). Yes i sound retarded saying that on a Honda forum, but things happen (which i know all too well) and college is always the best way to go. Just look at it like this, drive it like it is for a while until you are absolutely shure that you can afford to boost a car because it is very expensive to do so no matter what engine you have it on, I am shure that there are many many people that can attest to that here on honda tech. Then once you have money from a good job/career as result of college, then you can afford to modify your vehicles.

Re: Turbo SOHC or All motor DOHC....my conclusion (dirtyd463)
 

Consider the purpose of the car as well. If you are auto-x/HPDE, a turbo SOHC may be more likely to pop on you under the prolonged stress. Take the B18 and beat the snot out of it all day, go home happy. Plus the extra power adders on the SOHC would probably place it in a class where it would be in over it's head.

I am a big fan of the turbo SOHC route though, just as a fun street driven project. As a learning tool as well, you can't beat the cheaper price tag (a mistake on a B series engine could be much more costly).

i was thinking about a b16a and turboing it...

http://importbuilders.com/block.html

block package 8... a b16a at 1.8l and 8.4:1 compression... iron sleeves, the whole deal...

i figure ill get that and turbo it...

Re: (imk)
 

yeah, it's pretty hard for all of us to come up with a b18c1 turbo http://images.honda-tech.com/set1//smile/emcrook.gif personally the dohc vs. sohc debate has been going on forever(and i would think it would end already) but dohc always comes out with the most power most potential, but it all boils down to your budget. i bet most of us are still attending high school and just have a job thats paying minimum wage
