So Ive decided that I want to build my daily driver, 94 delsol Si aka the civic, but I dont want to go the swap route like everyone else. So Ive decided to build the D16z6. But I dont want just any old built SOHC motor, I want the BEST SOHC motor.

So, which head is the best of SOHC and which bottom end is the best?
I've seen several a6 bottom ends with Y8 heads, but I thought the z6 was the most sought after SOHC motor.

Lets hear Ideas for the Best MONSTER SOHC MOTOR IMAGINABLE!!! Turbo'd of course

 

It sounds like you want to be different, not wanting to got the typical route of an engine swap. I'm sure you mean, a honda engine swap. But if you really want to be different, swap in an engine from a completly different car manufacture. Maybe a turbo nissan sylvia engine(SR10DET i think it is called). Just an idea thought. but if you don't want something that big, you seem to have a hang up on small weak engines like the d series, then you can always install an older carbed engine from something. That would be pretty sweet. I'm sure there are carbed 4 cylinders out there that make the D series power. that would be pretty sweet i think.

It is the SR20DET and that for one is rear wheel drive, that alone makes it pretty much impossible. If you want that kind of power, purchase a 240.

 

good on you man.. im doing the same thing right now.. almost finished

there are front wheel drive sr20's, though it would still be mad $$ and time to swap it in, might as well do a rwd conversion while your at

What makes you think a D Series is weak?

BTW, Bisimoto has been using several different all-motor SOHC carbed Hondas and at one point in time was the FASTEST all-motor Honda (DOHC or SOHC). His best official time at a sanctioned event was 10.02 at 136.35MPH. I have heard he was the first all-motor Honda in the 9's at an unsanctioned event.

 

F22 accord engine swap, custom turbo w/ a GT28RS Disco Potato...you'll know what the word "torque" means after that...and it'll be plenty different.

 

Sleeve stock bottom end - build with pistons and rods

Port head, install valve train and cam

Custom turbo kit with Precision SC50 snail

AEM EMS tuned =

Nastier than you'll ever imagine.

Thanks a have a nice day.

Compared to a B,H,K (i could go on)series it is weak. Compared to a v6, a turbo 4 cylinder a v8 it is weak. 125hp, please... Yes someone made a d series powerd car run 10's. Big deal, you can make anything fast. The time and money spent on that engine could have made a different engine run 9's or faster. On the street where you can't safely drive fast, you can call a d series powered vehical quick. But fast is really stretching it. If a d series isn't weak then what is. A VW engine that has 60 or 70 hp stock? According to http://www.ssmoparmuscle.com/s...R=ASC
a 92 civic si wil run a 16.5 on its little d series
Do you think a 86 VW golf is weak. If so, then so is a d series. Both fun a 16.5.
How about an '83 toyota tercel 4wd wagon. Theres a speed demon, yeah right. Oh wait a sec, it also runs the same time as a civic Si which uses the d16z6 VTEC engine. Supposedly one of the quickest D's. 1/4 miles times are not everything, I'll admit. But the d's area weak engines plain and simple.

everyone is entitled to their own opinion.we dont want to turn this into a D vs everything else thread. the thread starter wanted to build up what he has instead of swapping motors. lets try to stay on topic.


beandip-
id personally go with a z6 or y8. whatever you have available to you.
thats a good starting point. sleeve it, slap some forged internals and boost it. it will be able to make good power. search around for posts by JFK78. he took his d16z6 and a greddy kit to 12's in the 1/4 which are very respectable in my book.

if you ever want to talk d series just pm me.

 

stock vs. stock, the z6 head outflows the y8 by far. the combustion chambers of the y8 tho, are smaller (more compression) and resist detonation better. The bottom ends between all the sohc d16 are equally as strong, stock vs. stock, though there might be negligible difference in ring-land strength between the pistons of the various sohc d16's, however, i forget ; )

allmotorEG-SI, your opinions are quite entertaining, however, are completely off-track for this thread ; )

If everyone thought like you then nobody would build a honda. Honda motors are pretty weak in general. Its just all a matter of personal preference.

 

LOL, you guys are all probably right. I'm going off track here and hating on the D's. I used to have a b18b in a red 94 civic si. Then it got rear-ended and i got another of the same car,but stock. now i'm just hating this torque-less D series engine. It sucks in my opinon. I guess i'm just bitter.

But anyhow I don't often find a fast D engine. So more power to you if your going to go all out on yours. I suggest maybe getting the head ported ,and bigger valves of course. When going turbo a better flowing head is always welcome. Good luck.

I don't want to hijack this thread, but I can't let you go talking a bunch of bullshit that isn't true. Compared to a B, H, or K it is not a weak motor. In fact, the SOHC non-VTEC platform is SUPERIOR in many ways to the DOHC Honda motors.

Also, Bisi is on a much tighter budget than his competitors running DOHC engines. So no, if the same amount of money he spent was used on a different engine, it would not be faster.

Bisi spent his money on education, so he would could make tons of reliable power with theory, R&D, and careful part selection instead of bankrolling some inefficient high $ engine with tons of high-dollar parts...

Okay...now I'm curious. In what ways would you consider them superior?

 

bang for the buck!

-Less rotational mass and frictional losses
-Valve angles allow for more radical camshaft profiles
-Port angles are higher and superior (applies to F Series)
-Spark plug placement
-Less parts
-Engine is much lighter overall
-and of course price

The only true advantage of a DOHC is the ability to tune overlap. On a SOHC it has to be ground into the camshaft.

 

imo... the main thing that kills it for D's is the head flow and valvetrain. port a d16 head and upgrade the valvetrain and it's honestly not too bad.
