Hi

[FreshDA9]

Hi everyone i joined to learn more about nitrous systems for a project im doing. im mostly into hondas and i see this boared has alot of domestics so i hope i dont get bashed to hard. well i have done some dry and wet shots in the past with adjusting the distributor but i am mentoring an efi tuner and am picking up well on programs. with my Hondata i have an option to run Nos control as well as being able to have a hidden direct port under my intake manifold with out having to use wet jets and adding more fuel from the engine managment. i have read some tech articles from here and have answeard a few questions already.

[evilbeef54]

welcome, i always love honda guys, they are so much fun to play with at the track, lol. Okay flaming over... for now... Sounds like you have some good previous experience, let us know if you have any questions and we will help in any way we can

[FreshDA9]

Thanks for the welcome! i have been looking at the jet calculator on the ny-trex site and i think i figured out my question with the direct port setup i wanna do so tell me if this is correct i wont a 75 shot or maybe a lil more.

this is how i did the calculator
Pressure i read on here to set it to - 1050psi
and jet size - .024
number of jets - 4
=
Predicted HP of - 104 hp 88.4whp

im asking did i do that correct and would that be close to a 75 shot or is it .022? i was thinking of maybe using a .026 jet making 125hp 105.4whp. Please correct me if im wrong.:notworthy:

[evilbeef54]

it doesn't look like you plugged any numbers in for fuel pressure or jets? do you still have a stock fuel system or have you upgraded that? Have you done any engine work? forged rotating assembly? Is it a 4 or 6 cylinder? General rule of thumb is on a stock motor you can be fairly safe with about 20 hp per cylinder, so 125 on a stock 4 banger might not be the best way to start out, unless you are planning on replacing the motor soon, lol. So you already have the system or are you still in the shopping phase? have you thought about your safety devices yet? how you are gonna activate it?

[FreshDA9]

havent bought anything yet. I have stock fuel system so far and im not runing wet jets because the engine management will take over the fuel and ignition for me. I do have a fuel upgrade i will be doing for when i do my boosted motor that i have been waiting to install. its a dual intank pump with -8 out and -6 return, i also have some RC 750cc that i will be using also in my turbo kit that i can use on the nos setup.

as far as the assembley right now its a stock dohc non vtec motor and i have a set of oem pistons that will bump the compresion from 10.2 to 11.8 to 1 compresion with ARP rod bolts. ive seen hondas all day long run on 75 but i was thinkin of takin it maybe a little more but nothing rediculouse. im going for a sleeper look untill i build my turbo motor next year.

Here is a pic of the pump all i need to buy is some line fittings and FPR.

O and i said 4 jets and on the site it says fill in fuel pressure if your running a wet system witch im not just runing 4 dry nozzles.

[evilbeef54]

okay, yea, a 75 shot should be just fine on that motor, i'm not sure how much more i'd wanna push it without doing some forged internals, 100 might be a bit much stress, although going DP you are getting a nice even distribution so that is good, and i think you are making a good choice going dry

[FreshDA9]

so i should just do 4 .022 jets. thanks for all your help. when i get going on this ill make a thread about it. now i gotta save and get all the equipment together.

[evilbeef54]

i would always start small, check your plugs, check your motor, datalog if possible, and slowly move up the jet size, making sure to check your plugs as you go

[mrr23]

welcome. all makes and models are welcome. we need a few more imports. spread the word.

[evilbeef54]

no we don't, back in your cage!!!!


j/k

[FreshDA9]

lol thanks for the welcome ill try to get more people on here with in the import communities. ill be around the forum looking into more faq's and when i get the ball going on this ill post up some dyno graphs before and after plus install pics.

[FreshDA9]

Well i figured ill post some pics of my car. its a 91 integra with a freshened up B18B motor and S80 tranny. so far i will be putting some P30 pistons in that will take my compression up to 11.8 to 1. also a set of ARP Rod Bolts will be holding the revs to 8,000 along with a set of new OEM bearings.

welcome! ... So when are you going to swap a K engine into it? ;)

Used to have an RSX Type-S myself. If I kept it, I probably would've gone direct port dry as well. Of course... that was a K20.

Good luck with the project. :thumb_yello:

[FreshDA9]

lol i had a CRX that i was doing an all motor K build but i stoped the project mid way cause i bought this and fell in love with this car. in the future ill get another CRX and finish the all motor K dream.

[jworl]

noooooooo. N/A is NOT best! :mfr_lol:

[FreshDA9]

lol high compression and nitrous are always fun:specool:

K swaps are overrated IMHO. H22a swaps are alot cheaper and better. More torque!!!

I like the DA!

[FreshDA9]

yea but H22 cant handle 500whp on stock bottom ends like the K's can. i was one of few doing the K swap way back when there was only 3 doing so. i lost funds half way threw and when i was back on my feet i ran into this DA and the CRX just feel behind. im concentrating on a tuning career right now and hope to open my own shop in a few years. thanks for the compliment!

[hammered54]

are those forged piston's?.. the ring pac look's good for nitrous down off the top, should use the hellfire ring's that'd keep thing's safe and maybe smooth out the top's a little.
nice looking motor should fly!!
Matt.

[FreshDA9]

no there OE replacements im thinking about sending them out for coating but not sure this is just a sleeper build im trying to find cheap ways to go fast that people wont see or notice. were i am people dont care unless it has a big turbo or vtec most dont even ask questions or even know what there looking at. basicly if im to pop my hood i wont the other person to just be like o just an LS motor i got this.

[D1sclaimer]

To each their own. With the extra money you have from buying the H instead of K, you could build a badass bottom end. I thought that Ks were only good to about 350whp since they don't have forged pistons?

Stock looking is always a plus. I've got mine hidden well so not many people know I have it. Its always funny to watch people talk crap about your car when they think its stock. :thumb_yello:

[FreshDA9]

i completely agree you could build the block and have a beast but also the K motors sit farther back in the chassis that also make it better to get traction and better weight distribution. I have seen stock K20a2's handle 500whp but the trannys are weak because they are skinnier gears because they tried to fit 6 into a small gear housing. the trannys will poop out between 300 to 600whp.

I have the same issue with people underestimating anyone i will ask a million questions about any car i see. people get to be smart asses when someone pops there hood but if you dont know anything about the person or whats in the motor you never will. when i do the nitrous my freinds wont know they know i have talked about it but never will know when i install it and take it to my buddys shop and tune it. i will have the solinoid hidden and the switch will be my AC button
http://www.hondata.com/images/nosdiagram.gifi will be using B5 AC Switch input going into my S300 where i will add the fuel and change the timing nder the conditions i set then will go to the Solenoid that i will hide probley under my dash and then a line out to the "Y" for the direct port sprayers. i will have a stock intake manifold that i will be hand porting along with cam gears and a set of cams if i can find some decent ones. that will all be covered by stock timing covers so know one sees them.:flex:

[hammered54]

all the extra stuff you want to do is great, but if you would like it to last for a while I would realy like to see you start with a good forged piston and then go from there.

if you want to you could beadblast the top's of them tape off the ring lan's then paint them with VHT high temp white and bake at 300 for an hour, it work's!!! then give the pin bore a little extra hone.
Matt.

[FreshDA9]

hmm never herd of that before i know about shot peening and getting pistons coated but never herd of using regular VHT spray paint. do you have any write ups on this, links etc so i can read more on this??? o and why hone the pin? you are talking about the wrist pin correct?

[hammered54]

no write up's, just an old trick that has been used long before they were coating piston's.
you will need the extra pin clearance because of the extra heat that nitrous produce's or you may end up galling the pin bore's, that would make it very hard to disassemble without ruining the piston's to say the least.

[jworl]

I'm not super H-series knowledgable, but everyone I knew with one said, "fiber reinforcement ftl" followed by a ---> :sad1:

lol. The K bottom end should be good to 500whp. There were many guys pushing beyond that even, but at that point, a build is pretty certain in the near future. I'd say a 400whp DD can be a very reliable car. :thumbup:

In the end, I got out of the Honda world though. Some parts were cheap and there was ton of knowledge out there, but to be honest... just wasn't for me.

What kinda dyno are we talking about? Dynapack or Dynojet?

[FreshDA9]

It doesn't matter a local honda shop has a dynapack and our shop has a dynojet have made the same numbers on both

[jworl]

What kinda dyno are we talking about? Dynapack or Dynojet?
seen mostly dynojet number. Dynapack is fairly common though (considering Church and all).

[D1sclaimer]

Okay. I was wondering about the 500+whp since the F20c5 tops out at about 600whp with stock forged internals on Dyno Dynamics and stock headgasket (not a 3mm one for lowering compression).

Makes sense then since its Dynapack and Dynojet.

So sand blast my pistons. the VHT paint i found are silicon based would that matter seeing it goes in the oven for an hour? how many coats you think? how does this help is it just to help from heat?
