General Civic Talk - horsepower estimate?

98 civic D16y8 Sohc with header, highflow-cat, catback, spark plugs and wires. Any one have an estimate of Hp?

You have a CAI?

135..............to the crank

135..............to the crank

that would be my guess, 140 tops.

ok mad sciencetists.. figure out mine if u want...

d16z6
4-2-1 race header
cold air intake
bosch platinum 2 plugs
and a crappy muffler strapped on to the stock pipe.. soo i know i loose hp comming out of the leaks in the compression of the exhaust... plus its an auto... but heck i have a good front end weight reduction

can you do mine, i have a b16a dohc vtec, 5speed, SRI, cat back exhaust and headers

around 135 to the crank, 120ish to the wheels.

can you do mine, i have a b16a dohc vtec, 5speed, SRI, cat back exhaust and headers
145ish wheel horsepower. (around 155 to the crank)

figure this one out:
4-2-1 race header (Pacesetter),
full 2 1/4 exhaust (magnaflow muffler),
stock cat!,
cheap ebay short ram,
68mm Holly Throttle Body,
Skunk 2 intake manifold,
Bosh Platinum III plugs,
APC fuel rail,
MSD wires....


i'm gonna wrap the header and short ram in header wrap....just to keep the motor a little cooler. also thinkin of some type of functional cowl hood....

***also--i am thinkin of gettin a lighter weight pulley....is it worth it? and maybe a cam sometime down the road....(BTW- these are just my plans... i wanna know what kinda figues i'm lookin at. :) thanks

B16s make a minimum of 160 stock, depending on what b16 he has. So he'd be closer to 165-170 at the crank.

What engine honda_man?

whoops, sorry. stock 96-00 lx (sedan)... sohc....i dunno the letter/number dealie... sorry.

130ish i dont remember exactly the base hp. isnt it a non vtec?

D16Y7. You'll be making about 115-120 at the crank.

kedawei, i have a jdm dohc b16a g2

for a cowl hood, you can get a stack of washers and longer bolts. put the washers inbetween the hood and hood hinges and bolt them down, the back will stick up and look pretty good imo. i also noticed cooler temps in the summer and my car don't overheat with no cooling fan when i'm sittin in traffic. total price $5 tops

Is that all? wow... I thought it'd be more then that.... the lx has vtec right?

the D16Y7 has got about 100 at the wheels and 110 at the crank stock, right? I mean... conservatively its got 100 at the crank stock... and ur sayin that with ALL those mods I would ONLY have about 115? thats pretty depressing... i may spend less time under the hood of my car than i thought. it just doesn't sound worth it. I can afford a motor swap(besides i dun want too) and I don't like forced induction. Plus bottles are for babies, and I don't wanna drag it. i just want it to be a little quicker than my neighbor's metro....

wow, i have never seen so much paper racing in one thread!

it the y7 a non vtec?

The Y7 came in the 1996-2000 Civic DX/LX/CX models and is non-vtec. It makes 106 peak hp at 6200 rpm stock. Honda_man, the best mods you could would be to preform a mini-me using the head from a D16Y8 (search for info on that), and swapping in a tranny from the Y8. The head alone will push you to 140-145, as well as boost your peak torque about 1000 rpm forward.

i would say he is at 110hp right now(with mods). but i would say stock he would be at 90hp

so on the 96-00's the only ones that had vtec were the damn ex and si's?! thats gay, i was told the lx had vtec as well. WHere would I go about finding the head off a Y8?

^ nope sucks i bet. buuuuuuut a head swap is an option!:)

the head swap sounds like alot of work... i guess it would be worth it. maybe i'll get lucky when i'm lookin for the car and actually find an ex sedan(from what I hear, they are kinda rare)

i wound up with a 01 ex with no truble... si's and hatches in good condition are rare.

yeah... i'd prefer a 6th gen though....:( sorry to sound picky lol. the more and more i see 7th gens, the more and more i like them, though. but no matter what, i hate the 7th gen sedan tail lights. [:'(] no offense. thanks for the help though.

the coupes are uber sexy, i agree with you on the sedans,[:'(].

but there is more aftermarket support with the 6th gens.

The 6th gens handle better, and look better imo. For the head swap you might try ebay, or your local junkyards.

the head swap is an awsome idea, i found mine on craigslist for 260 with everything. and the cool thing is the valve cover says vtec so i can sport it. i was looking on ebay for y8 heads and there are good deals on there too. look up vtec head and d16y8, it will bring up what you need.

aight guys i got one for ya.....99-00 si coupe with the b16a2, its got....CAI, no exhaust yet, but CTR cams, daul titanium valve springs, titanium valves, ctr crank, ctr pistons, head milled .030, and its port matched....what horsepower you think im puttin to the wheels, and in my heavy ass car what do u guys think on a 1/4 mile time? oh yeah and vafc vtec controller....


What do u guys know about a butterfly electronic cut out....or i believe that is what its called...its so u flip a switch in the car and it opens up the exhaust so that your running either open header, or right after the cat depending on where u put it.....thanks in advance

Where'd you get that from? It shouldn't be much, if any, higher than the 127 of the Y8.

Because of the mods he had listed...

can you do mine..... ahh d15something orother 16vlave auto... completely stock..... well not Cat on her

alright lets see my future power.
d15 block
y8 head
skunk2 stage 1 canshaft
aem cam gear
light weight pulley kit
skunk2 manifold
66mm skunk2 throttle body
aem cai
dc ceramic headers 4-2-1
tsudo cat back exhaust 2.5" piping

well i'm hoping i can be at least near 150-160hp, with fairly nice torque when i'm done with all of this.

Go with 2.25" piping. As for hp numbers, that's too tough for me to call. I would imagine you'd see better results with some fuel delivery tuning with that increased airflow, though. Uberdata maybe?

what the hell are you guys basing these numbers on???

i get my estimations off of a little mag called import tuner

Seriously... :eek:

:D

OKOKOKOK, doooo mine! D16Y8 with ****ty intake, header and an exhaust leak.


158 whp? That'd be my guess. Maybe 164.

I bet I can beat anyone across a standard 8.5x11.

your kidding right?^

^ you're kidding right?

That's about the most sarcastic thing I've said in a while, and I'm a sarcastic guy.:D

my bad... didnt catch it.

maybe this would help? i'm not sure

I was just pulling numbers off the top of my head. I thought they were pretty accurate, though I think I may have estimated a few optimistically. If anyone cares to refute them, go ahead.

Do me... do me... ooooohhh oooohhh... lol, sorry. If one of you is bored, could you guys that knows what your doing give me an estimate??? please...

95 cx hatch...
- d15b8 block
- z6 head
- z6 intake manifold
- y8 head gasket (middle section removed)
- cold air intake
- 4-2-1 header
- no cat
- 2.5" exhaust from header back

- NGK plugs

----- *** don't forget the NOS floormats :) lol.

i need an update, 94 ex with a jdm b16a with SRI, greddy headers, greddy evo 2 exhaust, and hi flow cat, 5 speed

eleventy billion horsepower!!!!!!!!!

hot94vtec id say bout 180-185 crank, bout 165 wheel

I got another car... can anyone give me a hp estimate???

I want to get it dyno tuned... but don't have the money right now, and would like to get it the way I want it first... what do you think?? thanks.

Estimating numbers without tons of mods can sometimes be somewhat close, but when you get into turbo stuff there is no way you can estimate it. A good or bad tune alone can gain or lose up to 30hp, plus mileage, gas octane levels and other things make it nearly impossible. The dyno will be your only way to get hp #'s.

I'll say this over 75% of these answers are like way wrong IMO

I know all this estimating is a bit gay, but id be interested to know a ball park figure of my civic if anybody can work it out ?

115 to 118whp at most

At the crank? going to get it done on the rollers soon so I should know for sure. I was reading a uk rice mag the other day called max power (I know, the shame) and one of the journalists in there has an ek hatch lsi, they have a 1.5l vtec and produce 115bhp stock, well this guy puts on a cat back, sri, and a 4-2-1 header and gets his car dyno'd and it has a 28 bhp increase to like 143 bhp! I thought this was a little high, but the print out was there for all to see. I wonder if the estimation they gave for the crank figure could be this far out ? hell of a nice gain if it was true though.

I said whp at the crank you should be around 132 to 136. People mistake throttle response for power alot.

So you reckon there's no way the 28 bhp increase could be true on his car?, typical max power didnt even quote what whp it was putting out.

No way in hell, you would need a good $500 header, a cam and valve terrain along with a tuning session with a decent fuel management system to be able to atain that out it. Akmee engineering is pulling around 135 to 138whp with a Z6 but they have a thuroughly built head on a stock bottom end.

And what makes it worse is all the ricer's who read that mag will go out and buy civic's thinking they can achieve massive gains with just a couple of bolt on's. Well they will if they can afford the high insurance:D

uh 04 lx comes 117 stock just wanted to put that in there

Okay. I'll play. I want to see what the future may hold for me too. Just bought the car and this is what it had on it.

'99 civic ex
D16Y8
AEM CAI
Some new exhaust tip but at least it frees up some air flow.

That's all that has been done engine wise as most of the mods are to the suspension and wheels.

What might I be able to achieve with headers/catback and IM? Also planning to put some light weight pulleys on it to free up some low end hp.
