12 sec all motor

[rota92]

okay, here it goes, now ahead of time, i do know this will take quite a while to acieve, and it may not work.

i have a d16z6 in a 92 civic hatch si. my goal is to have a 12 second all motor sohc. i chose this since i want to be differsnt, and i want to scare the crap out of people. i have thought this through and i have made a list of parts i think i will need to make this happen, along wit extensive headwork. i was looking into gude, but they seem a little stuck up, and jun, toda, spoon and other good jap companies dont seem to make a lot for it and some not at all. here is the list

jun cam(suggestions welcome)
light weight valvetrain (not sure who yet)
pistons, cranks, rings,and all the other stuff in there that i cant think of quite yet.
knife edge crank, (my dad thought of that one from the muscle cars)
new pulleys, cam gear
intake manifold(still deciding)
aem cai
header, (jdm civic, who would you go with, no 900$ spoon stuff)
exaust,
port and polish, maybe bore, can be pursuaded on that one, need pros and cons
then tranny wise:
quaife lsd
jun clutch(can get it relatively cheap, along with flywheel)
and maybe a final drive(more agressive, suggestions please)

please bring to my attention anything i have missed, i know i have.
also, im trying to keep it relatively cheap, even thought there is no such thing.
the motor has 184 thousand original owner miles on it.(my dad)
has to run on pump gas
thank you for all your help

[KaosFire]

a few things you might want to do:

-Strip out all air ducts and air conditioning equipment. (the HVAC stuff)
-remove the back seats and install a low weight racing seat.
-Since u plan on being ABOVE 12 seconds, u don't need a roll cage.
- i don't know that motors compression ratio, but it its possible, increase the ratio and change to higher injectors to allow the comp to correct the A/F ratio.

i don't know...you could do so many things.

[rota92]

yeah im gonna do all that, but i want to go under 12, and im gonna do a cage anyway, for a stiffer chasis

Your mindset is wrong.

U want to be all motor, yet u don't want to spend money.
U want to be 12s allmotor, with a SOHC?? and yet u don't want to spend money....

pick another route. for this one is going to be expensive.

First of all, why are u choosing all JDM companies? JUN clutch? What's wrong with ACT, Clutchmasters, and the thousands of other companies that can be contacted within the states....u save money on shipping...warranty work should there be a problem is much simpler.

Second...Spoon doesn't make a header for SOHC's, as far as i know, and its not 900 dollars for a spoon header. Spoon headers also do not flow well for high horespower applications..

In answer to all of your things that you were still deciding on or not sure of, the answer is custom. Custom cam, shit load of high compression.

Custom cam, IM, header-back exhaust, headwork to portflow or alaniz, big injectors and pump, bore the block (either do a small bit of bore, or go nuts, resleeve it, and have it bored out to some ridiculous figure), and some good engine management.

[rota92]

my friend has the clutch and flywheel right in his shop, so there fore it does save some $

now im not cheap, but i mean i want it to be realatively cheap, and over the last day or too in puttin the list together, i realized i have missed some thing, now i am still considering this, since the money is out of reach at the moment, but thatnx for the help keep it comin...

[JDM Civic]

do a bit more research and go with a B series engine you wont hit 12's SOHC for anything less than $8000. Not worht it. Youc an drop $5000 into a D16Y8 and still only dyno 150hp which is less that a sraight ITR swap for teh same amount of money...

[Anonymous]

^^ Agreed. Start out with a DOHC motor preferably with more displacement since you will need to utilize every ounce of potential (b20?). And as Toda said, use custom parts where applicable. Parts custom made for your application will do more for you than most mass produced parts. Also, weight reduction is critical. Remove the dash/interior panels, seats, A/C, cruise control, power steering, replace body panels with light weight components.. You can never go too crazy with weight reduction. Another key point is your differential gear ratio. Find one that will suit your needs. Am I correct in assuming this is going to be a balls out drag car?

[stockciviclx]

yea if its a balls out race car it can be done for less amount of money rather than if he wanted to keep his interior and not strip luxuries.

[A F'n J]

don't forget about the t-body!!!

yeah I hope you don't want to keep your car streetable, if you do there is now way you'll get in to 12sec all motor. But I see where your coming from and maybe these guys don't. your doing it for the chalange. I want to build my f22 for all motor. I don't plan on getting into the 12's I'm more looking for 14's. thats high 14 at that.

[stockciviclx]

oh i understand where he is coming from. I cant decide if i wanna take over the 4 door civic lx which is an automatic from my parents and turbo that or if i wanna start from fresh with and older two door in a stick which i know will be easiar. but hey i respect this guy for giving it thought.

[sleepycivic]

don't forget about the t-body!!!

you should forget about the t/b and run individual carbs or itb.

[Toda Party]

not on a street car, its not very streetable

[rota92]

okay, then what motor should i try to build up? i do like the challenge of the sogc, but more and more i realize it will take tona of r+d and money. now i was thinking a jdm gsr, 10 more ponies and an lsd for almost the same price, but then waht should i do? thanks for all your help

The SOHC will propose more frustration than challenge. You will ind yourself $5000 into your engine that is 10 yrs old and still only doing 14.0.

Get a stock ITR and get a good header. This is key!

my friend has a 92 hatch that weighs 1950 with him in it, Stock ITR, Spoon Header, Short ram Intake, 22" Mickys.

12.58 @ 109

He has body and suspension mods but as you can see a basically stock engine in the right car with a great driver these times are not unheard of.

[rota92]

i was thinking to save a little money, to go with a jdm gsr. 180 hp with an lsd. then later on if i wanted to, i could strap on a b20 block, then build it up. would this be a good idea? do you guys know about anyone with this swap? thanks for the help

[JDM Civic]

i say do it. Get the JDM GSR and drop it in. But first sell the GSR tranny for a JDM ITR 98+ you get shorter gears (makes you faster) and the LSD which you gave up...

Thats is a quick combo for about $4000 installed give or take......

You camn always build it up.

CRV's are great and all but why? So you can drop $5000 into your shorblock so you can actually ame compression and can rev over 8000?

Not worth it.

high revving DOHC VTEC engine OWN j00

[rota92]

cool, finnaly i have some decent direction, first i have to get some cash, but then after i get the motor, what other mods would be good?

[XAcidManX]

get a JDM B16 with an LSD so if you do go CR-VTEC you have a better head. Also its cheaper so you can do more mods.

[sk8rmike]

if you want to talk to someone who really knows their shit about the D series and making them fast go to honda-tech.com or darksol.com and talk to them...they love their D blocks and build them just to break 'em.

Not true... build a turbo kit, buy internals and boost it. If you know what you're doing, $5000 could take you a lot lower then 14's.

[fataLLightning]

this man want all motor. rock the H22. H22 are cheap now because everyone is blowing their loads all over the b series motors. my friends b18 hatch that was full weight ran 13.1@108~ish on a 1.7 60' time. this was a built b18 with toda Cs, high compression and revved to 9500+ RPM. sooooo. 12 seconds is not easy.

[92blackteg]

have you ever thought about putting a shot of nitrous on there...if you are going to build the motor ..why not try some n2o ...with that n the work you want to do you can make 12s with a sohc motor ...my boy basically did that only his motor was built for turbo n he took it off n put a 150 shot of n2o on it and ran a 12.6 ...but it none of it is cheap ...if you want let me know and i can talk to him n find out exactly what he did...if ya want

[rota92]

thanks ,but im still debating about the whole motor thing, im trying to get input on an h22 swap, but thanks a lot, ill keep that in mind

[92blackteg]

lol another one of my boys got a h22 in his hatch too lol ran a 13 untill he snapped his axles n he had stage 3's too lol ...either way i think its nice ...with the h22 i think you would have more to work with ...it all depends on what your personal goals are ...a 11 sec sohc is bad ass so is a h22 powered hatch...do what you want to do ... :D

[sprayed]

1950lbs for a 5th gen hatch with an almost 200lb hevier engine than stock + driver and all fluids is pretty light. what did his weight reduction consist of. may lead people believe its easy to accomplish. i dont think that car is very streetable

[rota92]

92 black teg, can you get me some info on his swap, was it hard and how he likes the handle ing all that other tech stufff, it would begreatly appreciated, thanks

[A F'n J]

if you still want to go all motor SOHC get a f23. strongest honda SOHC at 150hp about 60lbs lighter than a h22 and you can still say you have a SOHC. dirt cheap engine too. more torque than a JDM b18c at 1/4th the price.

[92blackteg]

he had an intake header and exhaust ....dropped on ground controls with agx 4way adjustables and g2s in the back ...he also had stage 3 race axles but that snapped at the track...and i kno he had hasport motor mounts ...thats all i can remember off the top of my head...and i rode in his car once and it didnt seem anything difference from my boys civic with a gsr swap...wit the agxs if was a nice ride ...ill talk to him prob 2morro and find out more....and its not as easy sa it sounds but its well worth it i think

[A F'n J]

oops double post.

[rota92]

92 black teg, thanx i'm realy thinking the h22 is the way to go

[RunninOnDuckSauce]

just get a stout engine (B series or H) and bump your compression to an ungodly level and do other mods...you'll be hitting 12 sec 1/4 miles in no time...oh did i mention you have to have a fire proof wallet for all this...because it isnt going to be cheap and your wallet could burst into flames at any moment

[rota92]

right now ive got my trust dict tape wllet on me, it wont burn.

but anyway, it will be a lot easier to do a dohc swap opposed to my sohc in now, it will cost money, but im not talking to do this all at once here, i have to make up my mind first. thanks for all the help, i realy do apprecitae it, ill be gone till jan 6th so ill be back then, have a good vacation, and merry x mas, drive safe!
