Tips for my D16a8

[geo41e]

heya dudes...just wondering if it is worth it getting an Apexi S-AFC II for my car.

currently running a D16a8 with Js racing air intake, headers and mufffler and soon a 2" cat back pressbend.

Now i know u can get cams, valve and valve springs, but thats alot of $$$.
If i purchase a S-AFC II, will this increase power by tuning it right from the mods i have currently done?

what do u suggest ?

[Mateoo]

Swap a B-Series
its hard to get gains out of a d16a8

but if ur happy with a little power increase not sure who makes agressive D series cams , crower springs to mind

as for replacing valves and valve springs cant see really any big gains there

aftermarket [acronym:9157afd2e3="Engine Control Unit"]ECU[/acronym:9157afd2e3] would be ur best bet and a good tuner

but whatever floats ur boat

y does everyone here the D series so much?
he asked a simple question about an SAFC and you give him a list of expensive options instead of answering a simple question.

if those mods are already in there then yes, you will benifit from, SAFC tuning.
it won't actually be much more power, but you will feel an improvent in power delivery.
not 100% sure on wat u can do with the SAFC but i was quite impressed after seeing the difference an e-manage tune did.

.. insert HATE or DISS or YUCKIFY i take it ?

Anyway...another can of beans opened here....Mateoo....you didnt help this thread one bit at all. Throwing a "veetekk" engine in isnt the answer to all lifes
problems , it wont get you laid AND it WONT make a shit driver any quicker.


Jeff - i suggest you join D-series.org !!! (http://d-series.org/)....and learn anything and everything about YOUR engine series...not from a mixture of opinionated google-searcheres.


See ya there Jeff :) [/url]

yeah nice ben.

dude there are heaps of things you can do to boost power that isnt too much money.
throttle body, cam gears, they arent that expensive.
whats your defintion of too expensive?
the d16a8 deserves more respect than it gets.

people swap engines like its the new chrome.
if you have had your car for a while and you know whats its done id say get some bolt ons and do some tuning.

[geo41e]

thanx beenss and others
by expensive..l mean more then 2K...coz cams and the other stuff are prety expensive...

oh yeah.and whats the point of getting adj cam gears ?? i thought it wus pointless if ur internals are stock. It just changes the powerband or something?

[pornstar]

geo, d16as are the dohc variant of the honda engine, if u can live witha lumpy idle, get some ahrdcore cams and gears, then ecu. good power to be had from that.

[geo41e]

how bad would the lumpy idle be ?
how much for all that ? do i need to change the valve and valve springs?

[geo41e]

oh yeah..and i forgot to mention
will that S-AFC II tune my car ? as in..is that enough to tune my engine ?

[Weq]

dont get an AFC, it wont do anything.

[Muckafutha]

i dun know about tuning for power but i got heaps of extra miles so thats good too.

[egSi]

sent you a pm geo41e

[pornstar]

lumpy cams just lift very high, and sometimes long durations too. it makes ur idle lumpy and rough, but if u see big NA drag machines that are v8s etc, they make that low grumble sound. thats waht it will sound like, and run like if u go too agressive!

as for afc, put it into the frier and see if u can make chips :)

[Mr. Focus]

D-SERIES.ORG is the place to find out all you need about the 'd-series'. trav (egsi) knows. he refferred me there too. i have learnt alot from there

no need to be an ASS!!!!!!!!!!!!
i gave advice on what i would do ok!
sorry to say but the d16a8 isnt the most exciting engine out there
and it doesnt respond as well as a B series to mods
so next time u diss someones advice eat ur ass

[Weq]

if he puts $2500 into his engine, the amount of money iut willt ake ATLEAST for a BASIC b-series swap, he will eat ur i/h/e B until the end of time.

[pornstar]

what can ya do for 2,500 weq?

[Mr. Focus]

i just gotta sya that i have a 'd' in my 89 genII and on the w/end i raced a del sol with a 'b' an he only beat me by half a car length. all i've done is added a pod filter. i dont even have an exhaust yet!!! b's arent the be all and end all of hondas

isnt the fastest street driven front wheel drive running a d16a8?? i think you'll find it is! check issue 99 of hot 4's. p.47

[saboteur]

I'm about the only D owner that hasn't posted in this thread, so here goes! Seriously though I don't know if you'll see much of a gain with just a more aggressive tune, you could prove us wrong though! 8)

No point at all for an " agressive tune"....when you are working with a STOCK [acronym:df314576aa="Engine Control Unit"]ECU[/acronym:df314576aa].

Remember kids , adding ANYTHING to your engine be it exhaust , cams , pullies blah blah wont really do anything - if you dont have a aftermarket [acronym:df314576aa="Engine Control Unit"]ECU[/acronym:df314576aa]/piggy back item to make the engine actually take advantage of its new bits.

D16a8's can go quick....just not FAST.

[pornstar]

ben man i think its time u get ur facts straight

[bennjamin]

ben man i think its time u get ur facts straight

Ive just worked 13 hrs lol and i dont really care...but for the sake of this thread enlighten us champ 8)

[geo41e]

aha..thats what l'm saying dudes...instead of going ape crap and forking out heaps of money for a proper ecu or piggy back ecu, would it be worth it to get a S-AFC I to tune my js racing intake, headers, muffler, and soon to be 2" cat back ??

[carbine]

So many armchair pro racers.

[geo41e]

dude..if u got nothing positive to say...then don't post anything up yeahh ??

what does it run down the 1/4 mile?
boosted or allmtr d16a8 ? coz i havent heard it b4
i know there is a b18 turbo powered EF crx doin 10 sec

for those who were there to watched me whipping a h22a type S powered ( 1988 prelude) they know that a stock internal d16a8 with bolt ons is not bad at all ;)

[denaro]

I agree with Weq. Why spend 4 to 6k on a B16A swap, when you could spend a bit on your D16 and make up the 20 odd kw difference between the 2 engines and have money to spare?

[Weq]

the only way to make any car fast, to make any honda fast is to increase compression or capacity. Weather it be a an 'effective' (forced) or static compression (pistions/gasket), it doesnt matter. A B or a D, it doesnt matter. If u want gains u have to do something along the lines of what i stated. I/H/E is as lightly modified as motors go. Gains are based on how poorly designed stock items are. Just because u gain 20hp froma I/H/E on a B, doesnt mean it owns a D cause it only gained 10hp.

In summary. Air+fuel = power. Figure out a way to increase both, and u got urself a nasty engine.

[Mr. Focus]

eg5---not sure what it does down the quarter but it is boosted

so 'weq' what ur tryin to say is that if he does spend the dollars and gets himself an SAFC-II to control his air/fuel mixture then it should be cool? or is he gonna hafta fork out more $$$ to get the effect he's after??

[geo41e]

yeha..somebody plzz answer my questions ?? issit worth it to getta Safc I or II to tune what i have now ??

[pornstar]

in one word, NO

power != dollars.

an AFC is not worth the money. U can get a light flywheel for that price!

Just out of curiosity. How many D16a8's have you worked on to have such an opinion?

...lol...he directed that immature comment to me latino - besides...after offering advice i have to go now and EAT MY ASS :roll:

Lets help each other out :) Not stroke our "minority" ego's :)

[Muckafutha]

yeha..somebody plzz answer my questions ?? issit worth it to getta Safc I or II to tune what i have now ??

in my opinion a safc is good enough. if u can get an itc maybe even better. if im not wrong safc is like a piggy back computer like unichip anyway. because u have basic mods on ur engine, u dun need to go for high end stuff like emanage or power fc. i tink with the safc u can gain a little bit of power from tuning. my own experience wif a vafc and itc tells me i can get a bit of extra power and extra mileage as well.

hope this helps. im no expert though so this is just my opinion

[LatinoHatchCrap]

The safc (in theory) will allow you to flatten the power curve and tune your air fuel ratio to its optimum level. It cannot however tune your ignition so you'll have to advance it manually or get a standalone that can manage it.
Is it worth it? thats completely up to you. If you plan to take it one up level and mill the head and add a more agressive cam its def a good idea to do it.

Joe

PS: Dotn listen to anyone. Its all advice in the end. Do what you want to do. With the right mods and tuning you will achieve at least b16a stock power on your current motor.

[geo41e]

orright then boiz...and girls...
l guess i'll get the safc after i get my 2" catback...and tune it up and also tunr the ign timming manually...via distribvutor right ??..who knows a good tuning place?

[joneblaze]

You've decided to get an SAFC based on all THAT advice? :O lol... I'm still not quite sure what's going on...
I don't think anyone has really technically and logically given you an answer and a reason behind that answer yet Geoff. Might wanna research a little more?

[pornstar]

man geoff, i said NO, NO NO NONNONONONONONONONO.
u cnat just adjust ignition timing by turning the distributer cap, u can advanve timing throught the whole rev rpm by doing that but not adjsut it where u need ot to suit ur AFR. SAFC = a POS, look at how many tuning points it gives u, the load and rpm spots are crap, worse than e-manage. The fuzzy logic of the ecu itself isnt good enough to extrapolate between the points well enough, so ur stuck with each aFR on the given tune points. but hey, whatever flaots ur boat man.

[geo41e]

ok o kok ..lols..thenn whats a good piggy back ecu that i can get to tune whats needed..and also give a display like the safc does ?

u guyz telling me that the S-AFCII ain't gonna help me tune my engine ?? with the lil mods i got ?

[pornstar]

nothing, best piggy back would be the unichip. but man, ur mods dont warrant any ecu or anything like that yet.

[LatinoHatchCrap]

...ur mods dont warrant any ecu or anything like that yet.
I agree. Read my post above.
Before you get the safc get your exhaust , cam, milled head and adjustable cam gear.
Then look into tuning.
Save the 600+ and use it where it matters now :wink:

[justinfox]

You guys are funny. Let me add my little but to this mess.

I used to own an Alfa Romeo 147. I modified the intake with a custom cold air intake and straight through exhaust system. Car was sounding fantastic, more response and I was pretty happy.

I then dynoed the car and wasn't too happy with the results as they equaled what the car is meant to have in the brochure! 110kw. So damn my mods felt and sounded great but power wise I hadn't made any at all it seemed.

I then spent the cash on a piggy back UNICHIP [acronym:494ca44ed2="Engine Control Unit"]ECU[/acronym:494ca44ed2] and a dyno tune and there is was. I got an 8kw gain from this damn expensive [acronym:494ca44ed2="Engine Control Unit"]ECU[/acronym:494ca44ed2] + tune. Was I happy with the money spent? in all honesty the answer is NO.

I very soon after sold the car and bought a car which had an engine which would respond very well to modifications (RB26).

Having said all this I am happy with my little [acronym:494ca44ed2="Single Overhead Cam"]SOHC[/acronym:494ca44ed2] Vtec to an extent... it's actually pretty punchy in 1st and 2nd gears (I rarely use 4th lol!) but I would like to try an engine conversion on it if I decide to hold on to the car for more than 2 years.

[geo41e]

justine..what did the unichip tune ?

[Denchy]

I have a 2inch zorst CAI blah blah blah but also have under drive pulleys in the D16y4, where in Brisbane would I be able to get a Unichip? any idea on how much. oh how do you know if the previous owner has fitted an aftermarket cam and upped the compression ( compression test?) as the bitch pulls like a mofo :)

[pornstar]

proper way is to open up teh headm, check teh cams urself, then while ur at it, take out an intake valve, pour that liquid i forgot the name of it (mon monrnoning) and then crank engine, that will tell u exact CR.

not sure who tunes unichip, but if u got those mods, why botehr with a piggyback.

It sounds to me like you were expecting too much from your alfa. I cant really coment however since I have never owned any alfa. However from your experience I can pick up a couple of things that need to be brought into account:

1. The alfa is not a honda.

2. Manufacturers' power output at the flywheel is only a rounded off figure which is used on brochures and magazines as a sales pitch. You should not use it to compare power figures even across two vehicles which are the same.
Let me give you an example.
The ITR is written to have 144kws at the flywheel. However on a base dyno WE KNOW that ITR will put down between 89-95kw/kw's. No two ITR's will have the same power output on different dynos.
In other words comparing what honda/alfa says on a brochure/magazine/website its not a wise comparison to ACTUAL information.
My suggestion to you would have been to do a base run WITHOUT the I/E and then do another run. That way you would know from the same dyno what benefits there were if any.

3. I/E do not net too many gains on n/a engine. We know this from experience. If you do enough reasearch you'll see that on a n/a motor the entire exhaust system needs to be upgraded (headers/high flow cat/exhaust)to net any decent gains. And also if you do enough reasearch you will also see that to get decent power from a n/a motor what is needed is higher compression/cams/headwork/tuning.

4. We know for a fact that most performance vehicles can net positive gains from tuning the ignition/air/fuel and no other mods. Some vehicles will repond better to others of course. My motor is living proof of this claim.

wow another D vs B war. :roll:

mad props to yonus for ****ing up that prelude :twisted:

and mad props to anyone that kicks a D and doesnt hate it. :twisted:

and well, basically i cant wait to unleash my D back onto the roads in
August. :twisted:

[pornstar]

sick, wanna race me in my b? :P haha jk man, im cool with d's as well, i like the d16a actually!

...........and i didnt loose it for DUI. :wink:

[Terry]

SAFC will give you a bit improvement.......for better result, go for a E-manage

[newmski]

sory to hijack but...
i have the d16a8 in mah Si...now that im looking for some more performance
the question is
because the d16a's are DOHC does this mean that say a "b16 - turbo kit" would bolt on
or because d-series i should go for d-series mods. im just curious as to the measurements of tube ligning up and manifolds..

b16 kit will not fit.

get any D SERIES turbo kit and that will fit

[Terry]

wanna to get a D can catch up with a light tune B? all u need is cold air intake,intake manifold.......header/intake/exhaust......agressive cam, value, light pully,light fly wheel, a 4.7 FINAL GEAR, strip interior + air cond, as for CPU u can use Hondata or VAFC. All this together yet still cheaper than swap a B in.....but the happyness of owning a fully tune car.....priceless

PS:A light weight driver also very important!:D
