50 - 100 hp nos kit on d16y8

[nisboi40]

hey guys no one can answer me on civic forums but just wondering
if i can run a 50-100 hp dry shot zex nos system
ive got an after market intake but stock headers and exhaust
would i need to up grade anything to run it , like cams intake manifold?
i wont be using it much just the casual wensday runs and once in a blue moon
cheers guys

with that engine, i think you should give it 1000 hp shot, forget the cams etc. Make sure you take a video though, you will get much pleasure from the 1000 shot. You can buy my dc5r radiator too to help keep it cool. You can stick it anywhere.

pfft alright mate dickheads like you shouldnt own a honda :)
any one?

Sorry, i'm very very very drunk.

its illegal to use or have it connected up on the road but
it would be very interesting to see what would happen
with double the power on the d series motor
do it as is no need for upgrade

[CRXer]

convert it too a wet shot or get some aftermarket fuel control happening

if u persist with the dry shot,might want to upgrade injectors as well,as honda injectors are generally on the limit as far as these sorts of increases are concerned.

above all get it setup on a dyno with reputable tuner,who can tell u AF's/timing are ok,thats if u have any care for the motor,if not ,just connect & drive.

[nisboi40]

whats the deal with wet shot??
440cc injectors be ok?
was going to do intake manifold
full exhaust
and cam, camshaft work..
and piggy back
i know some guys from insight performance they will do the tuning
lol i no its illegal but if they cant find it its not there ;)
ive seen vids on yout tube and the nos kit seems to be alright for the d motor:)
to try it would it be ok to use it on stock headers and stock exhaust ??

[beeza]

Well,if you do it,don't say you did on here or a cop may be round your house knocking on the door.Yes,they do that crap.

[nisboi40]

lol i no, dw thats not my car in the pic and i havnt installed nothing yet, its only a small tank illl have a hidden purge so if i do get pulled over quickly release it coz the only thing that makes it illegal is that pressuriezd gas in the boot and that its flamable

[CRXer]

dry shot adds just nitrous so u need the extra fuel from ecu/injectors.

wet shot adds fuel with the nitrous(generally thru the same nozzle),so generally negates the need for ecu work/injector work.

dont know much about d series engines but u might get away with a 50hp dry shot(my guess,this would be the absolute limit,so,i wouldnt chance it),but anymore & u definitely need the extra fuel work.

Good,sounds like ya onto it :thumbsup:

[B20NA]

ill go with a turbo setup for your engine they respond excellent to boost, with the vitara nippon pistons, pistons are cheap, rods are cheap, get an ebay kit with crome tune and you have a budget build with excellent power

search hondatech on vitara d series turbo builds

[nisboi40]

Good,sounds like ya onto it :thumbsup:

on to it like a fat kid on a cup cake ;)

hey man i have a nitrous setup and we are installing one onto my brothers D16Y4 motor the zex system is a really good system and i recommend it, i would also recommend a wet nitrous setup as you dont have to have any tuning for a low shot and the zex kit has a WOT wide open throttle switch and is one of the easiest systems to put in.
A wet system will inject nitrous and fuel at the same time so tuning isnt required.

however if you run a 75hp shot you will have to retard the ignition timing by 4 degrees if your running it on a stock motor and i wounldnt recommend a 100hp shot for a D16 will no tuning and inadiquate fuel supply you will risk blowing your motor mabe not straight away but eventually.

run with a 55hp shot it will be safe and you can run it all day and not have an issue with it as your only basically pumping more air in so its not that much different to running a mild turbo setup. really dollar for dollar its your best bang for buck upgrade!

[nisboi40]

Thanks for the info man helped me alot I'll pm
you tomorro just want bit more detailed info on the zex
Thanks again

You won't need to retard the timing at all with 75hp. On old big block Chevs you might but not on a multivalve EFI engine. I'd get a wet system and have it tuned on a dyno by someone who knows what they are doing with nitrous.

I would use a NOS nitrous system as they are much more widely known and much easier to get parts for should you need them. Zex kits rate their hp increases at the flywheel whereas the NOS kits will give you that increase at the wheels (roughly depending on tuning and the car). ie a 50hp Zex kit will give you 50hp at the flywheel increase but a 50hp NOS kit will give you 50hp increase at the wheels.

If you want to get consistent results it is necessary to get a bottle warmer and a pressure gauge. With these you can keep the bottle pressure around 900-1000psi. If bottle is not warm enough the pressure drops below 900psi and as it drops you lose performance.

It will be necessary to get aftermarket headers and a good exhaust system. Without these you will reduce the nitrous gain because the engine will choke itself because it won't be able to expel all the exhaust quick enough. Make sure you do not use it at low revs with big loads or you will find out what nitrous backfires do to inlet manifolds and bonnets (it is not pretty).

One more thing, nitrous is NOT All Motor. This thread should be in the Forced Induction section. ;)

Nitrous Oxide in both gas and liquid form (when pressurised or released in the atmosphere) is NOT I repeat NOT flammable. It is an OXIDIZING AGENT that enriches the OXYGEN concentration in the combustion chamber.

You've been watching too much Fast and Furious.

Should of gone without saying ;)

its still dangerous if its leaking or somthing because if the oxygen rich atmosphere reaches more than 23% its counted as a not stable enviroment
mayb not flamable but dangerous,
should be in forced induction my bad lol

[nigs]

It's laughing gas.........

[lookingforboost]

all pressurized gas cylinders have a safty release valve and will expell there contents if something goes wrong (theory) :P so it is recommended that you run a emergency release tube from the bottle under your car so that if it dose release the gas it goes out under the car and not into the cabin.

it is stated on the ZEX installation guide that for untuned motors running a 75hp shot they recommend retarding that ignition timing by 4 degrees so you dont have to, and i would put this down to the motor being untuned running factory computer after market tuned no worries :P

[VTECnique]

may i also suggest to upgrade the oil pump to a d16z6 (usdm) type, D16Ys oil pump isnt really the best for what its supposed to do. I/H/E will deff compliment the zex/nos system, & as stated before, a 75hp shot would be pushing it, to be on the safe side id go a 50 shot. bigger tb, skunk2 im would also let in a bit more air, & since your going to the trouble of fitting nitrous & getting tuned, may aswell go with them or get tb bored & port match im.

Keep your stock injectors, since your not hitting nitrous all the time, bigger injectors are really not required. only in application where boost is always present, then id start thinking about bigger injectors. if your really keen on bigger injectors though, prelude H22A injectors. im not exactly sure what size they are but i know they flow alot more compared to Y8s stock 240cc injectors...

[lookingforboost]

^^ as above but if you use a wet type system you wont need to upgrade your injectors as the system adds the required amount fuel to nitrous for you.

[CRXer]

honda push their injectors pretty hard,dont know bout d series but bseries see 90%+ duty cycle at high rpms.Id at least look at bumping the fuel pressure + tune,if stock injectors.

[grumpy rooster]

As lookingforboost posted there is no need for upgraded injectors when using a wet system.

If you only have a standard ECU I would not be using a dry system (I would never use a dry system anyway, but especially not with a stock ECU).

BTW, how many of those offering advice have actually used nitrous on a car of their own?

[grumpy rooster]

I don't know what your problem is but I did not flame anyone, nor did I direct any comment at any person, not even you.

And as for asking about how many giving advice have used it? I am genuinely interested because it is an area that has so much misinformation and misrepresentation it is ridiculous. Lots of people give advice based on rumour and what they see on Fast and the Furious. Most of it is total crap. I want to make sure those that are genuinely interested in it get the correct advice, not heresay. If thats a crime, well, tough.

BTW, I only ever state the facts. :)

in that case,my sincerest.......i obviously misread your post.....promptly deleted....

no have never used gas,but been tossing the idea around for a while.

[VTECnique]

IMHO, nitrous is just an expensive way to boost. have to get the bottle refilled, may not cost much to refill but in the end u add it all up.

D-series.org, alot of their members use nitrous, may just have some positive information regarding the right nitrous setup. i know ive heard a few guys on there use nitrous on there Z6s...

[beeza]

Yeah,that's where I would be going d-series.org,like you say heaps of guys use nitrious on there.

[lookingforboost]

me and my brother both have nitrous kits in our civic's EK D16Y4 running low shot its a great way to add power and for the power it adds for the price i reckon its best bang for buck.

[nisboi40]

thanks for the advice guys!!, ill be geting a wet shot system as its easier to plug and play :)

[lookingforboost]

let us know if you get stuck putting it in :thumbsup:
