*** D16Y1 - How Far can we go w/o TURBO??***

Heya chaps,

i'm curious to see how many others on ozhonda have this D-Series Engine and how far they've modded their engines without having top resort to a turbo kit??

Now i know that its debatable that the cheapest mod people can do to their d series is slap a turbo kit on it, but maybe there are people who want to get as much NA power out of this block without breaking the bank account. (?)

I'll start by letting u all know what power i'm reaching with NA Mods to my SOHC Vtec Beast..

ATW - 80kW.. not Bad...

Already seen a d16y1 hit 80kw atw.

All out D16y1 motor build, 100kw atw can be achievable.

when u say all out - what does that encompass??

rrods, high comp pistons, valves/valve springs, flowing the head, cams, intake etc

how much money do u have that is the question ?

any more then 100kw NA sohc den i would consider the dyno to be faulty =P nah jks. never seen an all out NA sohc before, wouldnt kno

hmm, according to Trism's description, my d15b4 would be considered all out.

but you dont really need rods, you can mill the head and mill the block down to bring the pistons closer to the head to bump up compression, but with cast iron pistons, i'd try to leave around a 2-3mm gap, or your pistons will hit your valves at around 7200rpm.

and it doesnt cost too much money. will only set you back about 3-4k if you know where to get the parts from and a good mechanic.

an all out build setup and tuned properly with the right ecu can net you close to 200whp. rushi on d-series/onecamonly hit around 180whp with ITBs, and bisimoto went either around 300whp or over it with a pair of dual sidedraught webers and a lot of fluid dynamics implementations.

Bisimoto = So Damn interesting!!

can be done. If your here to prove a D16y1 can make xxx amount of power then go for it.

But with that budget jump to a b16a and be happy.

To start off, get the usual bolt on. Intake/headers/exhaust + ecu and tune.

cool..

I/H/E are already done..

VAFC II vtec controller installed and tuned at 83kW ATW..

where to go from here..?

With $4k - do a B16 Conversion and you'll be spanking All motor D-series setups all day long.

As fatboyz said, not unless you feel that you have something to prove like guys some guys on this forum, working the D-series is a waste of money.

hmm...

only conversion i'd ever do to my EG is B18c and up..

but i'd like to reach max potential until i feel the need for a conversion..
heh maybe i am trying to prove something...

but you will be wasting a lot of money and you won't be proving anything unless you run a flat 14 or better...

by all means, go nuts. DO IT and SHOW us all what you can do with your NA D-SeRIEs Build! Who knows, $4k later you "might" be on par with a b16 with I/H/E wooha! Can't wait!!!!!!!!

Yeah but the B16a aint THAT much different from my current engine. only difference i see is that its got a shitload more aftermarket products for it.

and btw a k series engine in an EG looks 10 times hotteR! :cool:

what do you mean by it's not that much different to a b16a? you saying your car is keeping up with b16a cars?

Also don't take dyno figures too seriously because it's all too easy for the operator to make 'tweaks' and 'adjustments' to impress you with the numbers...

yes! the most recent was an EG3 with a b16a conversion.

poor bloke was trying to blame his vtec timing!!

i don't think that operators would make tweaks and adjustments as you like to call them..

Your money, do what you feel is right.. it seems like you like your D-series power..

99% of the people here will say its a waste and put it towards a engine conversion..

Go figure..

I was a member of d-series.org for a year before I joined here and they absolutely love the d.

LOL....

ahahahahahaaa!

LOL @ beeza.

But seriously i would love to work my sohc to be restepctable, and then when i'm over it... B16a or 18c..

IMO. I guess its how far you want to take it. Do you want some short term fun or do you want something with more potential for the future?

Not all that much power separates the b16 for the d16y1 . For the price of your b16 conversion (4/5k-ish), putting that money into quality mods IMO will get it going better. (I/H/E + Cam + Air/fuel Controller/tune of some sort). Also if changeing the y1 intake mani/TB to the y8 version (larger plenum & Runners) is a cheap and common mod.

It has been done locally & overseas mildly built n/a y1s outperforming factory b16s in the same car, for the same price.

Just remember though, alot of people do alwayes start off with small goals.. and then want bigger and better things once they have had a small hit. Building your n/a y1 will definately have a much smaller long term potential then swaping in a b16.

Regards Lyle

Thanks lyle!
Thanks for the tip with the intake manifold and TB also..

yeah that's cool, i'm probably gonna work the engine till its on its deathbed and then go for the big swap!

just keep my opinions as un-biased as possible. If you do have big performance goals for your car, it wouldnt be the best value to just work your current engine ... then get rid of it ... and start on something fresh again.

Ask yourself what you want as a final outcome. (power goal or 1/4). Then start work on 1 single setup that will reach it. Either boost your motor, swap in a motor, or work your motor n/a. Working your motor n/a is going to be expensive with minimal gains past a certain point. The max potential of a 4k n/a setup on your y1 would be a mid to high 14, assumeing your not overly weighed down. (educated guess based on dseries forums in the usa).

Do some research on honda-tech, dseries.org, turbod16 etc before you go jumping in spending money just for the sake of it. Dont make any decisions based only on what people say on ozhonda, as most are talking based on romour and "word of mouth"... rather then people on us forems talking from experience.

But if you happy with what you can get out of the y1 for the price you spend. Then knock yourself out and do it. Dont worry about what other people think. Your car, Your money .. enjoy it because thats what they are for.

Regards Lyle

of course.
i'm open minded and everything.. i know once i reach a certain point with my D series, i'm going to want more power and most likely swap it for a b16 or 18.

i guess its all going to be a learning experience for me..

i'd love to work on effective power gains for the d, (and the most useful info i have on this is just increasing airflow in all ways!)

i've even considered bolting on a turbo, but im a bit wary because it would be a never ending story after that.

Sure thing, im just saying.. If you know you are going to want a Dohc Vtec down the track... its just wasted money modding your d16y1. Save your cash or go strait for the swap or boost.. if you know you are going to want more power in the future then the na y1 will be able to give you.

Word!

just do a turbo d matey, you will be running consistant high 14s for life...

just be happy with the power now. The next step to make power will cost a penny.

yeah that sounds good..

so u guys reckon its not worth making more power even if later on down the track i'm gonna do a b18cr swap?

even just small mods..

if you know you are going to want something bigger or better down the track... like a engine swap or boost. Why stuff around with smaller mods that will cost you money? money that could be used to get you to your main goal quicker?

D - series will cost alot to make NA power, your better off just saving for a turbo kit.

The D series block was never meant to be a performance block, it was more an economy block.

I'd say go b18 with your money and you wont look back

Yeah,80kw in your d would be a real sweet car to drive.Keep it and have fun while you save for a turbo kit or a b.If you want to track the car the b18c is the go.

for shizz..

im planning to throw a b18cr in once the d16 karks it.
so damn hard to find tho!

Not so much a track car but a mean ass rex eater is what im after! - its all about the streets!

i guess i really shouldnt have bought this password:jdm CF intake then :p

actually, i think bone on onecamonly/d series has a low 13 second d, and it cost him less than 4k. but then again, its in an ED chassis, which is light enough to not need to be stripped.

i think bisimoto's original d series from when he first started drag racing cost him less than 3k to build and ran 12s.

honestly, theres nothing wrong with a d. power output might be low, but due to a lower valvetrain mass and cheaper parts, you'll end up spending less than you would to get the same parts for a b, and if everything is set up right, it will run on par if not quicker than a b.

as an example for cost, complete kms titanium valvetrain for a d costs $600, a titanium high revving valvetrain for a b can cost up to 2k. d series cams can cost around $200-ish for a regrind by bisimoto, b series cams are like $500-1k each.

oh and @Limbo, if d series civic motors and f series accord motors were never meant to go fast, then why is it that bisimoto can make them smoke most of the h, b, and k motors out there?

This is very very true.Ya gotta know what your doing.He and others have prooved it possible.Some of the d's on d-series.org can beat the b's.

How can you compare a highly established workshop which doesn't have to pay any labour cost, able to source very cheap parts and to fabricate parts themselve, has all the time and dedication to do R&D, to an average, non-automotive background person who just does the simplest bolt-ons to their Bseries?

where abouts can you get a 4k conversion in brisbane for a b16? id be super keen

Pm the man himself "barefootbonazi"

i've decided not to spend any money on my d16; i'm quite happy with what power it puts out at the moment, maybe cheap little mods from here on would be ok but the future goal is a b18c r swap ooh yeah
