im just waiting for them to come out with a reflash, ECU, HONDATA, tune...just something. i havent seen internals for it. i havent seen any NA people with intake manifolds.
i guess we just have to wait for the R18 parts market to open up a bit more.
all civic engines have a lot of parts...the D's, B's, K's...we just have to be patient i guess and wait for the R's.

 

see i am a patient person but i have a feeling that if there is no reflash or ecu upgrade for the R series in the near future that eventually other parts will not come out because the market will eventually separate between the si owners and the normal civic owners...but

having a 150whp R18 NA would be a great car and that would be my goal

if an ECU tune comes out i think many enthusiasts owning the R18 wouldnt mind spending $500-700 if they could see 150whp

 

haha yeah. i was impatient at first...but then i rmemeberd im driving in a car that has a engine built for mpg's.
i hope there will be a ecu upgrade at some point but honestly dont see it coming within the next 2 years.
150whp would be nice. i just wish we could get 200whp out of this engin NA but i dont see that happening.
but yeah a reflash would be great. raise the rev limiter and all that. im just waitin for a good reflash to come

 

Have faith,it won't be soon but rest assured that if there is a market for it(meaning dedicated people buy REAL parts and not E-bay crap then reputable companies will develope parts to help you out.It may take awhile but if you are dedicated enough you'll be rewarded...positive enough for ya'?

 

Nicely put.:yeahthat: :thumb:

 

get the weapon r intake manifold and then aem fic to tune it. You should net another 10-20whp. right now your car is not tuned for your mods. as for reliablility of the turbo as long as you do everything right there is no reliability problems.. my r18 is turboed and its starts up every day with no problems. the only thing is stay away from the 7lb flywheel as my car stalls out every now and then but then again i took off a 1/2 second on my quater mile time before the turbo, once i installed the flywheel.

 

Lets put a $$$ to HP ratio here ....how much did you spend total tourbing ur car and how many HP did you gain....... say you gained 35 hp net and spend say $500 then you ratio would be 35/500 = 0.07hp/dollar OR 500/35= $14.29/hp

Can you please let us know.....this kind of puts it in prespective to OP's question.

 

the stock IM though is really good because it is variable length and it adjusts...the weapon r really only benefits a FI setup because it is a metal box basically

i am sure this engine can rev higher than 7000rpms and i really want it to...on the dynos i ve seen the engine has a very steady power increase and i think with mods that 150whp is possible...is there anyway right now to raise the rev limit to like 7500rpm?

What are you talking about steady power increase. the SOHC starts to fall short past 5200rpms. A higher redline would be nice but not for the extra HP - just so you could pull longer in a gear.

The SOHC just doesn't flow the air to make power past 6000rpms. Thus the reason Si have DOHC.

 

Sorry to burst your bubble, but from a I/H/E and pullies, you might be lucky to gain 10HP at the top end, and youll prob lose a bit of HP down low.
If you think thats worth it , go for it.
Our R18 is designed for fuel economy so everything we do to try to gain power is like cannoeing upstream. Also, the car is heavy, and youll lose warrenty upgrading the pullies, and header.
Dont believe those tuner mags, those companys make more money the more you spend on car parts, thats how they pay their bills, so thats why you see them making major power from mods. Its all a setup.
If you want to really tune a car, go get yourself a mint old school civic, and mod that.
Its lighter, parts are in abundance, cheaper, they dont have a computer monitering everything, its got a better rear suspension, and some of those old engines are awesome. B16, b18c, h22, go with one of those.

 

Tisk Tisk..... Sorry to bust your bubble.. Lol.. but if you look at the CURB weight of the Civic Sedan. It's is roughly 3600 lbs... No they are rating that at 150lbs per person. With 5 people in the car.. So take away 750 lbs. Then they are also counting for 300 lbs of luggage in the trunk. So lets hit the math subject


3600 - 750 = 2850 Hmm.. Not to bad..
2850 - 300 = 2550 Wow.. Thats pretty light if you ask me..

Now comparing to a 92-95 Civic
Yes they only curb wiegh out at 2400 lbs. And actual weight is roughtly 1800 - 1900 lbs. I would say the newer Civics arent that kmuch heavier.

 

pulleys will void warrenty??? anyways i just want my car to have a little more power and be a little more fun to drive...im going to have it for a while so i might as well have fun with it

i agree that the car is heavy but im not too disappointed that with me in the car it weighs 2800 lbs...and pulleys gains r throughout the whole rpm range

i agree seriously tuning an R18 is somewhat comical but there has to be something to have some fun with

 

pks17....
2800lbs is heavy for a car? since when?
i mean..its no civic hatch...but its only like 800 lbs more than that.

 

My R18 weights 2,630lbs with me in it, and i weight 180lbs, so subtract that from the car and you get 2,450lbs thats how much the The R18 lx weights, i weighted my car last time i was at the track.

and yes this car makes a great power curve, it goes up and up until redlinle, i am boosted so maybe thats why.

 

i wish i had a car that was around 2000 lbs curb weight...lotus exige :vtec:

 

haha... the exige is my dream car...
the elise is affordable...but then...repair and maintence.... haha.

back to topic though...parts will be comin out like crazy for our car in 5 years. haha

 

yes same idea going on in my head lol...anyways is that how it usually works parts come out almost a decade after the car was made? explain please

 

alright...i am not 100% sure...but my dad is a major business man...so from what i have learned from him over the years is this..

Companies are all about supply and demand. everyone knows that. as of right now...those companies really only see the r18 owners as peoplewho wanted a MPG car...not a car to modify. So thats why we dont have many parts yet, but parts are starting to come out. What will help is, those companies see cars at car shows and all that, that they go to...so then they see more civics like ours and see that they actually have a market that they can make money off of. So as more and more people with our cars start adding the parts that are out there right now....those companies will make more because those parts are selling good. That leads to better parts as well...cause they will put in more labor on the product and be willing to spend more money on the development of it.

Thats an overview of it. So as long as they see a market they can make good money off of...then they will spend time and thier money on it. thats why the K-series engine took off so fast, because it was in all the more sporty hondas and acuras, and those companies saw them sell fast and knew the owners would want more power and make them stand out on looks because those owners bought that car for its performance.

our engine has been in existance for 3 years now...and we keep getting more parts now. so companies are starting to catch on.

 

Honda spent LOTS of time and money to squezze out ever possible bit of torque and HP. They left us very little room to improve on anything. Engines that gain from mods only do so becuase there were either poorly designed, within noise/EPA rules, or the mods makes the engine less reliable (turbo cars ECU flashed for higher boost). Basicly the r18 is what it is. Nearly every bit of power from a SOHC 1.8l you can get.

Reflash is a pure waste for the i-vtec on the R series. We allready have vtec on tap.

Cold air intake will help slightly.

header hasn't been show to improve anything

catbacks also help slighty

pullies are a huge warretny issue and not worth the cost or power.


-
only option is r20 lower block. and/or light weight rims, ceramic coated stock header (mine is heatwrapped and downpipe is coated). Or see if the 6 speed K series trans will bolt up.

 

well wouldnt the basic I/(downpipe)/E create more top end power so we would see a little benefit from a higher redline?

also does anyone feel like 3rd gear is really long or is it that our car is just straight slow?

 

The SOHC just doesn't flow air. Thats the choke point is the SOHC valve size and design. The choke point isn't soo much the intake or exaust.

Yes 3rd gear is long. Its a economy car not the Sports Inspired Si.

 

ahaha get a turbo and 3rd gear will be just right

 

eh those honda engineers...too good at what they do

now that we have confirmed that our car is almost at its peak NA...what do we need to improve?

ryker kept the stock cat and downpipe and ceramic coated it? wat cat-back do you have? tell us about the improvements with the exhaust (if any)

 

every engine made is not almost to its peak. if it was...here wouldnt be a need for aftermarket parts.

and what do you mean we "already have vtec on the tap"? we have i-vtec...for low cam...that saves us MPG. we only have half ass vtec on the tap.

its simple to understand that there are things that can be done to give this engine more potential.

 

every engine made is not almost to its peak. if it was...here wouldnt be a need for aftermarket parts.

Never said every engine was. The r18 is. Its about 8 years newer than the k20 series.

The r18 is made to peak performance within limits of budget, reliablity, and EPA. Any mods done to improve power are becuase they alter the budget, reliablty or EPA.

Ie a cold air intake requires metal tubing and longer install time and makes too much noise.

and what do you mean we "already have vtec on the tap"? we have i-vtec...for low cam...that saves us MPG. we only have half ass vtec on the tap.

Excatly. Reflashing our ECU doesn't have the same effect as the K series. Our vtek is MPG and Normal mode. Nothing can be done to change this. We have all the vtec power that can be "on tap" as is.

its simple to understand that there are things that can be done to give this engine more potential. but our engine is hiding power right now. honda puts a restricted ECU on our car. they do on all of the hondas and acuras....thats why HONDATA is around....cause they have an improved ECU. simple as that.

More simple to think that a few hundered people with 4,6, and 8 year college degrees and decades of experience spent months on design of this engine platform. To acheive as much power and MPG as possible from its 1.8 liters of displacment. No other 1.8l engine makes as much power and gets as much MPG. Show me another 1.8l engine that makes more power (torque and HP) than the r18 at 140hp and a nice flat torque curve.

The Scion 1.8l engine is what 130hp?

2009 GM 1.8-Liter, I4, VVT-i, 16-Valve, DOHC, SEFI Engine; Front/Transverse Mounted With Horsepower Of 132@6000, Torque Of 128@4400

A early 90's Eclipse 1.8 was about 100hp

Old Porsche 914 1.8l engines had less than 80hp.

No other car manufactor makes as much power from n/a 1.8l and yet you think Honda limits the ECU on purpose. What purpose is that and how do they limit power by the ECU?

 

My stock cat is heat wrapped. If i could find a used cat it would have been ceramic coated. My downpipe is aftermarket and is ceramic coated. The catback is a cheap ebay knock off.

I actually don't drive my car hard so I can't say about any power improvements. But I did notice the engine bay noise is not as loud - my guess is the engine is working easier so there should be some improvement.. Some not a bunch.

Also have my stock airbox covered in heat reflective tape to keep air intake temps as close to ambient as possible. Removed oem resonator and routed air intake inlet to front bumper area.

----
The only other source I can think of improvements would be to pull the head and have it ported/polished. Slighty higher compression pistons. and/or use a r20 lower end.

 

^our heads already come that way i think. correct me if im wrong. but yeah...i think they are.

but our engine is hiding power right now. honda puts a restricted ECU on our car. they do on all of the hondas and acuras....thats why HONDATA is around....cause they have an improved ECU. simple as that.

if we ever get a ECU for our car...we will see power gains...if we had better compression...that would also help.

 

^our R18 isnt at it peak. period. i know our car was built for reliability, EPA, and budget...and we all know aftermarket parts will
...but have you looked at the thread ur in...he wants to know about performance parts.
that hands on...taking time installing the parts you bought to make ur car better performance wise..he wants performance...therefore...i think he wants noise. i want noise. i cant stand the little sound. i gotta hear something.

i agree our vtec is MPG and normal. there may be a possibility in the future to change this.

yeah its impressive how much power the 1.8l sohc engine has...but it had more potential than where it is at now. yeah we have 140hp at the crank....but there are always way around every engine to get more power.

yeah our car was the grocery getter of the civics today...but you only look at it as a civic with a trunk. you need to open ur eyes a little and understand the potential of EVERY SINGLE ENGINE ever made. this one is no diffrent then the rest.

 

We have 140 at the crankshaft here, thats nothing special its about the norm for a 1.8L n/a. even back in the 90s that was the norm. eg. 93 integra had 143 hp froma 1.8,not sure about the torque curve.
But i guess the r18 is alot cleaner burning engine, and other "green" stuff

Golf didn't make 140hp in the 80's

The b18 DOHC 1.8l made 142hp but didn't have the same torque band as the r18 and only had 142hp becuase of DOHC allowing for better air flow at high RPMs.


Show me what SOHC 1.8l or even 2.0l engine makes more than 140hp in the 1980s?

 

No other 1.8l SOHC engine makes more power.

2nd - Dyno testing on R18 parts have yet to show any real power gains.

 

I think maybe you should word it... "have yet to show any real power gains that are worth the money."

The aftermarket parts do give us gains, however they might not be at a price that is reasonable with the amount of gain.

....that is....unless your loaded, lol, which alot of us arent.

 

Yah man, pullies will mess up your warrenty. when you change your pullies, you change your crank pully, alt pully, and sometimes, waterpump pully, your crank pully is connected to your crankshaft, if you put that bolt on too lose, or too tight, your going to mess up your bottom half of your engine.
also, if you tighten the belt too tight, its gonna put strain on your entire drivetrain.

If you dont know what pullies are, dont buy them. Its all these tuning magazines that are messing with your minds

 

ur killin me ryker

we arent going to get 15hp out of a cai.
we arent going to get 15hp out of exhaust
we arent going to get 20hp out of pullies.

we arent going to get any "real power gains" out of this stuff because it takes a bigger engine to get more power. we are still going to get noticable gaines though.
if you do full exhaust/cai/and pullys....your DEFFINITLY going to feel a diffrence.
10hp is a diffrence.

lets say we have a cai
1.8l r18 civic gain- 2-3hp
2.0l si civic gain- 5hp
2.2l s2k gain-7hp
4.6l mustang gt gain- 8hp
7.0l 06 zo6 corvette gain- 12 hp

its common sense....the bigger the engine...the more hp potential you can get.
