Hey guys! Just wanted to open the discussion on D turbos.

I've seen in another thread about H,B,K Series debate, so I've decided to open this thread with the advantages of having a D :)

Each engine has their pros and cons, but personally the D is the most underrated engine, yet the most mysterious..

So guys, just a few questions to start off!

- PROS and CONS about the Turbo D.
- The GENERAL BUDGET for a high comp low boost setup (5-7psi)
- Legality issues with the Turbo D including engineering cert and costs.
- People's OWN OPINION about what setup they would personally do!

All other Honda enthuisiasts, please have an open heart towards the D! alot of people would do the build to be DIFFERENT :)

Well please post genuine and appropriate comments towards this thread and please rep if you like ;)

turbo d-series, better than goin for b-series swap imo

To give rough estimate, turbo d, with stock exhaust, an injectors, 5 psi = 100kw easy!

Give it a 2.5-3 inch exhaust, some 440cc injectors and full ecu, prbs closer to 140kw :D

This is just a basic of it, obviously theres more to it though, and especially the engineering cert if its gonna be a daily

My mates got turbo his d in his eg, never looked back at n/a, using greddy turbo kit, budget all up closer to 2.5k

If I was going to turbo a D I'd probably try and do it as cheap as possible, in the spirit of the engine! Probably ebay manifold, old turbo from a Nissan or Mitsubishi or w/e, I already have a 60mm mild-steel exhaust in my shed somewhere, cheap intercooler, the whole lot. See how cheap you can make power. Would probably be a lot of fun and I'd love to do it...

D for Different!
This is exactly how the car industry needs to be viewed.. Styles, trends, whatever.. They're all started by somone doing something different.. And a bunch of others liking it, and doing it too!
Doesn't matter what car, what Engine, what mods.. If it's different (And awesome) you've got yourself a winner.

And when you say high comp, do you mean standard compression?

generally, turbo cars of the 90's relied on low comp to add more boost = power unlike all the new cars of today, high comp, with boost, soooo in turn, yes its consider high comp on the d-series the standard comp.

the only thing u dont cheap out on is the tune, this is the make or break part. Highly recommend Rev zone if ur in melb, they tuned my mates car with GREDDY E-manage.

And when money permits, definite get HD clutch, odds are the power is too much for oem clutch, an will be gone in matter of minutes if u keep pushing it..... Fuel pump, injectors and most important, the most expensive part, LSD.

As far as quality of turbo goes, anything thats off another car, thats in good condition, an the seals are fine, an not much shaft play is good enough. If its water cooled bearing turbo, even better. And if its a Ball bearing, win win!!!!

pros: if anything ****s up who givs a shit its cheap anyways.
goes good as, best bang buck all i can say,

general budget: i spent more then 4k on the turbokit coz im picky on parts and not even finish.

cons: if the setup aint engineered then pigs r going to book u and also insurance company will reject ur claim.
too much power in it then it will throw a rod out the engine block.



own opinion: its fun as, beats alot of cars, if u people r planning on boosting a D and not building the engine and using it for daily then a small turbo like t25 would be best suited.

but end of the day i kinda regret doing it should of just bought a new car instead.

peace out.

Thanks for the reply guys!

Yes D is for Different haha completely agreed! its only because its the dark horse in Australia to boost Ds in comparison to the yanks.

Yes high comp mean standard compression of the D.

My mate said that ebay kits are NOT bad. They are good if you know your turbos, if everything fits correctly then too easy. But if things need to be replaced, then let it be replaced, all in all its a d turbo set up, at the end of the day its different from the typical b series build ..

But guys just wondering .. how much is it to get it engineered? also .. reputable tuners in NSW? I know a few .. but they tune nissans so id best stick to the guys who know their hondas.

yes and guys, my car is a daily so im only going to be pushin 5-7psi MAX. Obviously id push more later on down the track, but my first purchase is to cheap out on getting an ebay turbo kit then picking up more premium quality parts from there.

And I agree, its all about the tune :)

I hear the SOHC D's hold about 140kw max, and once you put 140-150kw they throw rods.


If I wanted a turbo setup that didn't hit full boost until about 3,500-4,000 RPM what size turbo would you guys recommend? Because if ever turbo my D16Y1 I don't want it to be spooling so quickly so that I can still rev it to 2,500-3,000 without chomping through the juice so hard...

mugen_ctr
15-07-2011, 06:09 PM
Nissans T25g from the black top SR20 :D, reason im saying the black top, is due to age, as all type-X 180's are from 97 onwards and odds are they havent been boosted past 10psi.

They spool easily under 3k rpm, and enough to hold u to 140kw, good for upto 160kw than after that, they run outta puff, if u really wanted to push the budget, the T28 off the S14 is another good upgrade, than obviously the expensive S15 T28 ball bearing turbo

Skyline R33/R32 turbos are again nice addition, but anything past 10psi, say good bye to the exhaust wheel, but will lag due to the size of it

Even the WRX turbo are great upgrade, but again if aiming for bit more power, they start to run outta puff..... ive seen few ppl in the states use turbos off a volvo an even diesels vehicles.

few other cars that i cant think off to rip out the turbo lol

an yeah sucks that we cant push more than 140kw, before it spits out the rod, but a rebuilt one on the other hand, with parts that isnt too pricey, might be worth looking into :D

dougie_504
15-07-2011, 06:23 PM
Yeah, but what if you don't want it to spool below 3,000RPM, but rather above? This way you can drive without hitting boost all the time if you don't want to.

I see where ur coming from, awhile ago, i use to drive my brothers S15 heaps of times, an it just flutters constantly with no BOV, cop bait imo

Doesnt matter what turbo it is, its just how u drive really. Just cause a turbo comes on quickly below 3000rpm, doesnt mean it will constantly be under boost. remember, boost come comes on hard when u push pedal to the medal. I can say for a fact, driving my mates eg, with the greddy kit, it never hits boost, unless u want it to, an that turbo, is the smallest u can get, td04 turbo, for those engine, anything smaller, u will choke the motor.


Driving off boost is like driving any other car, untill u mash the throttle :D

im running a t28 and i get full boost at 4000rpm but boost starts 5psi at 2500 rpm.
hope that helps ya question.

i also get alot of wheel spins in 1st an 2nd gear when hiting full boost.

im not sure how much its making. havent dynoed.

im going in for a full tune along with my mates cars as well so prob in august/September once clutch is in along with vti gearbox, fidanza flywheel,new gt28 turbo, full 3" catback, 750cc injects, hondata map sensor, electronic boost controller.

so i be getting it tuned at 12psi. dont care if it bails on me, i got a d16y1 along the side which im building from top to bottom and going drop that in next year.

I'd like to bring up forth this question that causes me to be abit concerned about dturboing..

What are the legal requirements? engineering cert? how much? what needs to be done to be able to pass legally? is a 5 stud conversion neccesary?

You obviously need the engineering cert, to 'certify' that the vehicles handling is ample for the power you now have.. Also as proof that it isn't some half-assed job that'll blow a hose and leave an oilslick and a burnt out Honda sitting on the freeway.

Non-atmospheric BoV.. IIRC you can't get Atmospheric's engineered.
Has to stay within emissions (There are some exceptions)
As far as price.. Jump onto the RTA website and find the list of approved engineers, call one up and ask him!

I rekon they'll get you to uprate your brakes.

sorry to bring about B series, but i've seen some engineered with DC2R front calipers.

you probably dont have to hassle yourself THAT much, but you'll have to do something about it.
Is the car rolling on drums or disks? should change the drums maybe.

just something to think about. Especially if its a daily.. you dont wna be coming around a corner too fast realising that your brakes are fading.

Im no engineer, but i agree with you... if ppl with eg/ek do a engine swap, they have to do the same with the brakes, what ever the engine came from, it must use similar brakes or better....

Better off doin the ITR brake upgrade for that peace of mind considering u already paid well over 2-5k for a good amount of power/speed

trism
28-07-2011, 07:05 PM
That is correct. An engineer will take into account if the brakes are sufficient for the power that the car has.

on something like an EK4, if they do a k swap, then the brakes may be classed as sufficient.

But if you do it on something like an ED that has tiny brakes up front and drums on the rear, you will be required to upgrade.

You might only need to do say, an ITR front upgrade, and leave the drums at the rear, or you might need to go to disc. Its up to the discretion of the engineer

Turbo D's are a great way to get into boost and learn how things work on a budget..
BUT only as long as you can stay happy with smallish power and boost on a stock motor.

Hope you've read my build thread on turbocharging a D series completely legal and insurable

Ebay kit, emusa was the brand, $1500 including a power run on a dyno. Would cost more to have it fit by a workshop.

T04, external gate, dc2r exhaust, no other mods at all, 2.5lbs boost = 92.9fwkw.

http://farm7.static.flickr.com/6061/6119438673_f3afe83971_z.jpg (http://www.flickr.com/photos/oxerdan/6119438673/)

D16Y8

Boost is controlled via gate spring, had a stiffer on in it making 7lbs, at 5500 rpm made 88kw but was way too lean. An aftermarket fuel pressure reg may have been able to drop more fuel in, but being stock ecu the car goes into limp mode (Floods the chanbers, raises revs)due to the vacum dropping past 0 so rather then do that we put a softer sping in. Now it only throws a code when its given stick.

Hondata is key, More fuel, more boost, more power. Good for 140fwkw. I have a dyno sheet at home somewhere... meh.

Run bigger injectors and a walbro 255 fuel pump, FPR will help as well... slap a ecu/tune, an you should see 110kw easy!

Than later upgrade to a larger exhaust, atleast 2.5 imo, get a boost controller, up the boost to 8-10psi and should hit the target goal

and slap a pod filter on lol.... thing looks naked as with no filter...

im running my stock d16y4 130kw for about 2years, t2560r, 2,5'' full exhayst at 7psi.
ems stinger ecu, 255lph fuel pump , 440cc injectors, fuel reg along with all the little bits you need to make it run.
its running great but i am planing to update the head, the single cam just not cutting it anymore.
my question is, is there any point in rebuilding the head. or do i just go the B series motor?
also what D series twin cam head bolts up to a D series sohc head??

dougie_504
04-02-2012, 11:53 AM
None do. Your only chance would be to drop in a shaft for some more power, otherwise build the block. or get oversized exhaust valves for a SOHC vtec setup as SOHC vtec only increases intake valve lift duration an not exhaust (which is why SOHC vtec sucks).

Do you drive it hard? I'm surprised the y4 block is holding up with. 130kw atw without snapping a rod.

im running my stock d16y4 130kw for about 2years, t2560r, 2,5'' full exhayst at 7psi.
ems stinger ecu, 255lph fuel pump , 440cc injectors, fuel reg along with all the little bits you need to make it run.
its running great but i am planing to update the head, the single cam just not cutting it anymore.
my question is, is there any point in rebuilding the head. or do i just go the B series motor?
also what D series twin cam head bolts up to a D series sohc head??

Dude just go the B16/18

The difference is massive

I went from a D16Y1 with 135kw to a B16 pushing 160kw

1/4 Mile PB

D16Y1 135kw 14.5

B16A 160kw 13.2

The power to the ground the big diff in delivery and smothness

^ Have you got any proven results to share in regards to needing oversized exhaust valves for a Sohc Vtec turbo ?

No, I'm just offering a suggestion.

It's common knowledge that SOHC VTEC sucks compared to DOHC VTEC (for modifying and power output etc) and one of the factors is this - that the SOHC VTEC only affects intake valves, whereas the DOHC affects both.

This is why engine builds like Adrian at TODA recommend using standard VTEC B-series valves in head builds (most of the time). It only makes logical sense that oversizing SOHC VTEC valves would help it to breathe better in VTEC.

Mate im totally aware of the operational principle on both Sohc & Dohc Vtec... i can also appreciate the reasoning in what you are saying. But honestly even Bisimoto's 700whp 9sec sohc ... has not adopted that theory. If you are going to the effort to run oversize valves - IMO - you do BOTH exhaust and intake.

It is correct you cannot use a Dohc Head on your Sohc block. If you are chasing more power, you need to understand that you are reaching the limit you can achieve on your current setup and standard engine. IMO you only have two options and both involve removing the engine from your car.

A) Abandon your setup - sell everything and put towards a B / K Conversion
B) Rebuild your D16 with forged internals (Pistons / Rods & general freshen' up) and a Sohc Vtec head aka Mini-me (aftermarket cam, valve train, Pnp, head studs)

Hey Guys,

I've just trying to figure a few things out.

i have a JDM EF7 CRX with a D16ZC (DOHC) considering putting a little bit of boost thru it (6-7psi) and am just wondering if its best to go Turbo or SC? i have a feeling turbo is the better option + Cheaper.

i have been looking around and it seams the only kit that works with the d16ZC is the Greddy kit with a bit of modification.

would anyone know where to source one from? i think there are a few versions, i would be looking at the one without the FMIC etc, just manifold, ecu/tuning, turbo, injectors rah rah. FMIC i should be able to source myself.

Is it worth doing? i know its not a massive amount of psi (6-7) but i wouldn't mind the crx having a bit more poke.

Thanks,

Nuzo

Turbo IMO.

There are a few kits available, I have some of them bookmarked at home (at work atm).

Greddy, Turbonetics, TSI etc. All will have the same manifolds and probably just minor mods to piping for FMIC etc.


Will post them up later.

Most of these should fit man. Some may need minor mods for the chassis itself, but the manifolds etc should fit.

I need a run down on what I need

EK CXi D16

Grabbing this manifold:

Getting a t2>t4 adaptor to run my spare rb20 turbo i got lying in the shed

Will be cutting the welds and re-welding it if I'm not happy with it when I receive it

What else do I need ? Just a basic run down, costs aren't necessary as most fab work ill be doing myself

Thanks in advance!

The HKS D16 manifold kills the Greddy but their rare had hell in AUS dude

And like 3 times the price

cheers man, looks like a plan T3 log manifold of ebay will have to do, since greddy dont sell them, and hks is rare as fuk

BTW, which would b better to suit the build? TD04 off 2000 wrx or Sr20 T25g?

Ive read that TD04 runs outta puff at 5000rpms, and since will be running low boost, it will be out of efficient range from reading the turbo map from what ive been told, which kinda makes me think about not getting the td04, but its in mint condition an well priced :/

Hrmmmm not doubting anyones word, but i dont really plan on making that much power lol, looking tops 200 - 250hp......

but ended up buying the wrx snail... mainly due to pricing lol.... but got a long and windy road to go, much customizing and much fabrication :D

Already ordered the flanges to custom make a t3 to td04 adaptor... thinking of something like this....

My goodness! hey guys its been awhile, my car has been down in the dumps due to personal reasons of not wanting a Honda anymore. Change of heart I'm back in the game! still deciding on a b18c2 conversion or a d turbo! I started this thread such awhile ago and its really good to see people still talk on it :)

So guys has anyone practised their preachings?

would love to see some results that people have gotten!

but just wondering, is it possible to obtain more power than a b18 with the same budget as a b18c2 conversion?

thanks guys!

Kj.

dougie_504

Surely yes. To put a b18c2 in would surely set you back $4-5g if you're paying somebody to do it?

16-03-2012, 04:46 PM
Fair enough :)

I just wanted to ask you guys a few things first,

I wanna get a d turbo setup with not having to remove a/c?

I wanna get it engineered, how much would it cost in total? I've already got a stock exhaust tip so its quiet but running a buddy club spec 3 with genie headers, just a stock tip to dim it down.

and how much would it cost to get a turbo set up just get 110-120kw atw anyway?

what are the most important things to consider getting first for the set up?

Just a question. Have you searched? Not just here, but google it, so you get results all over the internet?

You might notice I rarely ask questions. That's because everything I've ever wanted to know has already been answered plenty of times in the past. All it takes is google, and half an hour of your time. And you can find the answered to your questions.

Just a question guys - after much deliberation I have decided for something different and for more affordable and fun power to go with the eBay kit - however can anyone recommend somewhere in Brisbane to install and tune?

Glad I found this thread too, going to boost my ZC soon and I'm just looking at tuning options since it's OBD0. After some research I think buying a chipping kit and tuning it with TurboEdit would be the best option. What do you guys recommend? Should I just convert to OBD1 and run a stand alone?
