D16Y8 noob

[Idoru]

Hi guys,
Sorry to ask this question as i'm sure you're answerd it a million times b4 :D

I've got a civic coupe 97 isr, with a D16Y8, so far i've got a ractive superflow air filter, and just a mufler, so tell me (and remember that i'm in portugal, so no turbos(can't get them here)) what's my best option to gain as much horsepower as i can w/o a turbo? Also regarding price :D

TIA!

NOS!
If you can't get that, then up your compression and get a cam with some wild lobes on it.

[Ek9]

get a nos kit :D

[Idoru]

not for dragging, for constant power, i've heard that cams aren't any good w/o ecu tuning,
plus for nos i need better pistons right?

If you want constant power, your D-series is going to need a little massaging :D.
For starters, get another y8 head and get it ported and milled. Milling will increase your compression, which equals power. For every point of compression you go up, you will gain about 10 whp. So say your 9.6:1 y8 goes up to 11.5:1.....thats a 20 whp increase right there. The porting should net you another 5-10 whp. With those mods alone you are close to b16 numbers. Throw in some good management, a good cam, and some bolt-ons and you have yourself a single cam screamer!

[Idoru]

i'm sorry, but being portuguese sometimes technical terms evade me :D
ported and milled?
means?
And btw, what else would you reccomend?
ECU reprogram not an option,
Is a gasoline pressure valve an option for my current setup?
TIA

Hehe...sorry. :D

Ported is usually used in the same sentence as "polished." Porting is done to the cylinder head by using special tools to remove matter from the walls, effectively "opening up" the chambers to allow more air to flow into the head. Polishing is done after porting to assure a smooth air flow tract. Milling is done for 2 reasons - increasing displacement and creating a FLAT surface for the head gasket to sit on and prevent leaks. Special tools are used to remove matter from the bottom surface of your head. Usually, heads are milled anywhere from .020" to .050". Any more than that and you risk jumping teeth on your timing belt because it will not fit right.
To go along with these mods, I would suggest good management from either Hondata (which requires OBD2-OBD1 conversion) or a hack like a VAFC, a fuel pressure regulator (B&M), and an MSD ignition box with an external coil. When running higher compression than stock, you need upgraded fuel and ignition systems in order to avoid detonation. Dyno tuning is also HiGHLY recommended. If you do not have access to a Dyno in Portugal, I would be VERY careful doing any intense mods like these. Tuning is mandatory for high-compression motors if you want them to last longer than a week!

y cant someone ship you a turbo anyone now days and get anything anywhere

[Idoru]

i can have someone ship me one, but it's just too expensive because of customs and all, really :evil:
My only concern in doing that is pistons and valves, they should also be replaced, and for what i can see it's pretty much the same price as buying a B, plus less reliable, dyno tuning no, you can dyno and then ride back to mechanic :D
As for that conversion, how does that work, btw, where can i see your material, maybe i can arrange something that will pass in customs w/o prob :D

Sorry went off the track, so by doing that w/o ecu management i can really damage the engine, and i can't reprogram the ecu, only buy from EU, meaning that if just port and mill my head i'll be doing crap to it.

[12secrex]

damn i dont want to live where you do if you cant adj fuel and timming or chip the ecu then stay stock i can ship you a turbo ups and make it would make it to you fast

[Idoru]

but still w turbo i need ECU and pistons right?

[12secrex]

you dont need pistons you can do other things other then ecu's you can ship me your ecu and i can chip it for you for 100 and i have a drag turbo for all for 1000

I have a d16y8..............I started with a intake and airfilter. Then I got a header. The header really helped alot. Then i got a cam, and a fuel pressure regulator. I also purchased an adjustable cam gear. This combined with some time on the dyno, proved to be a great setup.
127 horsepower........110 torque to the wheels. This is without ecu modification. Next I purchased a nitrous system(dry) add 45 hosrepower to the above figures, and you can see that im pushing 170 horsepower. Not to shabby for a single cammer!!!
Oh BTW i have a ton of Portuguese freinds.........we drink Sagres beer.

[JDMd15b]

The d16y8 should be running 127hp at 6800rpm in completely stock form...

[Anonymous]

wrong, you are looking at the manufactuer's FLYWHEEL hp spec, which is called "bullshit HP"

there is something c alled drivetrain loss which is about 15-21%.. usually avg 18%.. so 127 -18% loss = about 104 HP to the W H E E L S

so 127 to the wheels is very good.. about 23whp gained... and 127 to the wheels is = to about 155 FLYWHEEL.. so he's close to a stock b16a

[Idoru]

cheers toddnos :D nice setup you got there, you come here often? :D
and 12secrex sorry but that too expensive for the risk of turbo and damagining the engine, as i can see the cheapest and most reliable way to gain 30hp (flywheel) is to swap for a B, wich anyhow will give some better performance :D

TIA!

[Toddnos]

.........never been to Portugal. I have a ton of Portugues homies here in Cali. I go to the Portugues hall for dinner and drinks occasionally. I also know a few bad words as well.........as for the b swap being cheaper. I say no.........I spent maybe 1500 bucks for everything, dyno time as well. B swap will be well into the 3000 dollar range when all is said and done. I would suggest beating the hell out of your y8 until it dies........then swap. Thats been my plan for years........my poor old y8 is just now finally loosing compression after five years of total abuse.

[12secrex]

to swap a b-series in not cheep your looking at 3000 for 1000 you can get a turbo on there is no thing a cheep 30 wheel or flywheel power and be good to drive it for a lomg time. but good luck

[Idoru]

as i say it's cheaper here, i can't get the parts here for that price remember VAT a and customs, and no ecu dyno tweaking here!!
so it's cheaper, and plus i have no support from a mechanic when it comes to turbo :D

well i call WHP = bullshit !1 cause when in EU we dyno the crank ! mine had 124 stock (honda says 125) cause what ever rim/drivetrain and shit you mod the why we do it ! it correct it !! ;) cause we messure the "loss" in the trian and from simple formula calculat the RIGHT hp every time and can then be compred with stock info or others !

and for trainloss : the loss in a tranny is a SET number ! like 10 or 40 HP loss !! NEVER % ;)
i seen B16 with 23 HP loss and some with only 14 HP loss (difrendt gearolie) those 2 B16, the one with only 14 HP was stock (159HP mussured)
and other 176 HP messured

but they had
stock one = 145 WHP
mod B16 = 155 WHP ! thats only 10 HP in difrendt but a sec fater on the 1/4 mile but on the crank/fly = 18 HP diffrents ! :)
the moded B16 has from the start had about those 20 HP loss ! :)

THX for your time !! :)

sorry for the bad spelling im from denmark ! :)
and new 2 this board ! great site since im ALL OUT D series fan ! :)
dont go 2 hard on me ! :)

[Idoru]

zeus can you find good parts there?

[zeus zore]

zeus can you find good parts there?

well we get most from the US or germany !! germany makes some nice parts !! and is only a 2 hour drive from here !! :) and free speed limit !! :)

[Idoru]

hum, what would you reccomend?
