alrighty, im running an EJ civ, Y7 motor... im thinking of keeping it and mini-me swaping it with a y8 vtec head. and running NA, or turbo.. i want to turbo cuz i like the power gains from it, but i like NA cuz u can get the same from NA as u could turbo, with less maintience, but from what i hear is much much more expenisive? is this tru yes or no? and also, i dunt know much about NA and i want the best NA engine i could buil myself, i was also thinking of swaping like a b-series, and definately wanting to go NA with one of those, but i also wanted to see what i could achieve with my D-series engine, but what would be the best for NA on a b-series ?

Loco Honkey

Yeah, OK. When was the last time you heard about a 250 HP NA D series? Or how about a 500 HP NA B series?

Do a search. All your questions will be answered. This has been hashed, rehashed, cooked, fried, hard boiled, and regurgetated many times.

SOHC_MShue

what he said

1 2 NV

think about it ********. how many true built NA cars r out there vs the IHE cars. most ppl do not do full buildups. even though there r tons on HT. u cant compare NA race cars vs turbo race cars. think about true street driven machines.

GumballNA

well, one of my friends has civic hatch, NA, run's 10.9 et's, he can beat another civic hatch, thats running HKS turbo, with 175shot of nos, i dunno u tell me, i know i was already planned on getting flamed the **** out of me, for this but o well, once in a while there is a person who comes along and gives me a good answer...

Irishweird00

I asked the same question man n/a or turbo on the same motor... got flamed.... I say do what you feel is better for the car and your budget. I wanted to go n/a cuz all i want is 150 at the wheels.... cuz its a daily driver... and i cant afford a swap or turbo setup.... so from a fellow dx owner... DO what you do

GumballNA

ya thanx dood, but i was just seening how much of a cost difference would be, with turbo or NA, i rather run NA if it would be better... but if turbo is cheaper, then ill go cheaper.... ya know

Noe Kozz

ok, I was feeling sorry for you getting flamed, until you post up this crap.

Irishweird00

In the end its cheaper to just slap a turbo on, but if you want more than 200+ horse.... you will need to build up your engine either way. sleeves, p&p, pistons rods..ect.... but I know a sohc n/a can be done and make alot of power... but plan on spending alot... depends on how much you have... just like me... broke as a joke...

Don't expect more then 200whp with a fully built camed out, ported within an inch of it's live D series VTEC motor. Won't happen. Even Hondata would have troubles pulling that out of an all motor SOHC VTEC. Expect to spend upwards of $8K. Just get a swap. Or run FI.

10.6 all motor? From a SOHC motor¿ Even a B series hatch all motor gutted and tube framed would be super expensive to get into the 10's.... hard to believe man.

sethm

If you put in aftermarket pistons and raise the compresion does it change the way the car souds alot.

there isn't many people that build up there cars around here so I had to ask on here (it's been geting to me)

GumballNA

well tell me who has the fastest all motor civic? and whats it run

D15VTEC

If you have a friend running 10's in the quarter beating cars running boost and outragous ammounts of nitrous, then you need to go ask him how to do it.

Thats a magic trick I have yet to learn.

The Destroyer

i take it ur car will not be streetable at all.

Foozball26

your friend probably runs 10.9's in the 8th not 1/4

no way to do that with a d-series STREET car

Loco Honkey

OK, I'll think about it, because obviously you didn't.

Not as many because those that are serious about power will NEVER waste money on building up an NA motor.

...because the HP/ $ ratio is so low compared to boosting.

No way! Tons of cars on HT! You gotta be shittin' me.... All along, I thought this was HARLEY-Tech! ******' A...

No ****, so why are you trying to tell me NA cars will be as fast as turbo cars? There's no ******* comparason! In the allmighty quest for HP, the two deciding factors are displacement and volumetric efficiency. You with me so far, sparky? OK, so guess what a turbo does! It effectively INCREASES both VE AND displacement! WOW! Do you understand this now? Do you want me to draw you a ******* diagram with colors and pie charts and ****?

I am. I know you're not, so let's do some simple math...

Stock '95 Si hatch- 125 HP.
Add headers ($300)
... exhaust ($450)
... intake ($200)
Total cost: $950. HP gain: 20 HP if you're lucky. $/ HP ratio: $47.50 per HP.

Take all that **** off and throw it over the fence into your neighbors yard and add a Greddy turbo: $1500.
Total cost: $1500. HP gain: 65 HP. $/ HP ratio: $23.07 per HP (and you get more HP too!)

*edit- let's cut the magazine racing bullshit. I don't care if your friend can push his car to a 7 second standing mile. Speak from experience or shut the **** up. This goes for everyone that's replied to this thread.

all stock

who said it was d series?

GumballNA

ok my bad then, i didnt know NOS was considered FI, im still a noob, tho that is common sense my bad, im stupid but o well.... then he's not all motor, but he's pretty damn fast, i know the shop that i go 2 for my parts, has a 11sec. all motor... no nos, no sc, no tc.... no nuttin... i looked myself b4 if i remember correctly...

TurboFryBox

(Type-X) From your first post it seems that you think that an NA is something you put on your motor, its not. NA is Naturally Aspirated wich means naturaly breathing. NOT forced ie: Turbo or Supercharger. Therefore you cannot have an NA motor if you have a turbo. If you would like further explaination, let me know.

GumballNA

WHOA NOW! lol... im not that stupid... im stupid but not that much...i know what NA is, i just didnt know that NOS was considered NOT NA, so that was my bad... but i know its ALL motor, no TC,SC,NOS, etc.

beeseries

i believe erick aguilar hit 10.64 fastest all motor honda

*edit 10.24 @128
heres a vid of a 10 sec run [url=http://ericksracing.com/images/texasrecord.avi]

I just asked about pistons and higher compresion

TurboFryBox

Sorry to jump to conclusions but this line kinda pointed me there:
Either way you are going to spend a lot of money getting a car into the 10's

Travis

t-blizzard

explain...

Evs-One

simple....with a boosted engine, simply turn down the boost for daily driving....15 psi for daily-even less, and 20 for track. This puts a LOT less wear on components and still aloows you to have fun on the street.

With NA, you're always running the same compression, no matter what. I know a few people running 12.5 to 1 on the street, and it's not too fun. Too much for tuning, etc to make it a dependable daily beater.
