Yes, I read the FAQ, thanks. Good start.

I'm leaving behind a 600+ HP automobile and this is quite a shocker. While I know I'll never get there, I'd like to improve performance WITHOUT making it sound like a go kart. It is important to note that I WILL NOT do anything that will screw up my warranty...

What are my options?

First, airbox. Does the stock airbox actually pull air from under the hood? If so, this is a good place to start...

Intake: AEM or Injen? Are either noticeable improvments? Is water an issue for the "cold air extenders" or whatever they are? Why is this an issue if I'm not lowered and don't plan on driving in deep puddles?

Any value in a throttle body?

I'm not doing catbacks or cat mods. I don't want a big pipe sticking out of the back. What will it sound like with headers and stock exhaust system? Waste of time and money? Does anyone make a 4-2-1 for the 04 civic VTEC engine or just the 4-1? If not, why?

Maybe a discrete nitrous setup? What will the stocker take without having to modify the computer setup? 35 shot? Dry? Wet?

tires... I saw the tires in the post, but is there something close that has great handling AND will work on wet roads? It rains a lot in houston....

What else?

thanks in advance...

Go back to your other car

 

What type of car did you have before if you don't mind?

Just about all of the things that you are talking about doing would void your warranty if i'm not mistaken. Any engine modifications will void the warranty ie: changing the throttle body, and headers.But then again I don't work for Honda, i'm just assuming that is the case. Good luck in your search for HP, but keep in mind with these little engines TQ might be better,harder to come by...but better.

 

If you change your TB your warranty will be voided.

 

dont know about to many aftermarket parts for the new EMs' i know they make intake and cat backs but u said u dont want one. why would u get a header and not do n e other exhaust work? to me that would be pointless cause ive seen the stock exhaust on those things and the pipes are very small.

Nice... That really helps, thank you.

My other car is a twin screw supercharged ford truck. 20psi on a built block. It runs 11s in the 1/4 weighing about 5600 lbs. Look at a hp/et calc and you'll see that's well into the 600s for RWHP.

It costs me about 50 bucks a week (currently) to fill it and requires that I take care of it.

I've gone to the other extreme in buying a daily driver with awesome gas mileage. I guess I'm dreaming to think I can make this little car "zip". I probably should have gotten a mazda3 since I'd be starting with 160 rather than 127, but 30+mpg and being the quality of a honda is hard to pass up.

If Honda is as hard on warranty work as ford, best bet is to leave it stock for me. I don't have time for headaches right now nor do I want to be constantly worried if my tune is spot on so I don't launch a rod through the block.

the comment about torque is spot on. For those that don't know, HP is a function of torque. HP=torquexrpm/5252 or 5250 depending on who you ask. So, yes, torque is what I'm after. The sooner you get peak torque and the longer you hold it, the more HP you make. RPMs are the key in small motors... It overcomes the equation.

Will honda ding me for an intake even? Maybe I should just leave it alone...

I agree.

 

I'm a lil discouraged here, there has been a long battle between imports, euro's and domestics and here we have someone from the domestic camp crossing the line to imports. And the only thing some of you can say is go back to your old car? I mean seriously, if you're not gonna help, then why bother commenting. I'm sorry but I'm just dissapointed in the lack of actual informative responses this person is getting, as sappy as it sounds, I feel that situations like this is the first step in actually uniting car enthusiasts rather than keeping us apart. End Rant.

Oh, and btw, I would check with your dealer on exactly what voids your warranty. I know my friend with an Audi S4 had an aftermarket bolt-on exhaust, intake and BOV's and he was still covered under warranty.

 

You can't touch ****, and expect the warranty to still be intact.

I suppose you can change parts back and forth if something comes up and requires a warranty service.

However, if you change springs for example, and an engine part fails, depending on the dealership, they'll still cover the job under warranty.

Besides, to add zip to the car would require some major parts, so stick with the stock stuff, and enjoy it for what it is.

You bought a car that'll mechanically outlast your desire to own it.

Yet another remarkably intelligent post. Another one has escaped from the shallow end of the gene pool. Thanks so much.

I came here trying to get some help and I get this. I know my HP, I can assure you. I'm trying to get a good head start and was hoping to get some data. Gimme a littlel time and I'll give back -- but I need some time to sort out engine codes, body coes, etc. etc. etc...

I'll check with the dealer and see. There is one Honda dealership here in houston selling all sorts of aftermarket, including Jackson Racing. I'll see if I let them sell it and install it if they will still honor the warranty.

Assuming I bought a Max turbo and kept it conservative boost-wise, what kind of FWHP woud I be able to pull out of it.

Second, If I smoked the stock motor, how much to buy a new one? $14,000 for my last one, lol....

 

Uh, trust me, just cuz a dealer selles aftermarket parts doesn't mean they'll honor the warranty. I know from personnal experience as I came from the BMW camp. A dealer will sell aftermarket parts made for BMW's that suppose to be covered under either it's own warranty or the dealers, not all dealers honored the warranty and alot of ppl got screwed. Case in point, owners of the new Z4 plopped down an additional I think it was 80g's for like mild hp/tq upgrade, what they weren't told was that in order to make some of the parts fit, the front subframe needed to be "modified" customers walked away with a shitload of money down the drain and no warranty.

I dunno the stock specs on the 04 Civic but I know that the D16Y8 outta 96-98 EX's pulled 170 or so with the Edelbrock bolt-on turbo and I think the open track is like 200 something hp (someone correct me if I'm wrong) In any case, good luck with your pursuit.

 

Motor Swap..K20A

I don't think Motor Swaps are covered under warranty.

 

no offence or nothin, but comin from a built domestic motor car, u should know a lot of the mods that sacrifice warranty/ give decent results....

maybe thats just me

but, ill tell u this, that thing isnt gonna scoot if wanna keep the warranty

my advice, nitrous...take it out when goin to dealer, more than likely it wont work out, but thats the only way...u cant just take off a turbocharger when goin to dealer, so this is the only other way to get decent numbers

No offence taken, but ford has become a warranty nightmare. There are people that have had thier 03 cobra drivetrain warranties voided becasue the dealer could see shredded rubbern in the wheel well...

I was sure hoping honda would let things like intakes, headers, throttle bodies, etc. slide, but it sounds like they won't... I guess I better just learn to like it stock.

 

Unfortunately for you there is not as much aftermarket support of the EM2 as there are for the EGs and EKs. There is a thread in another section that might help you....

Alright, here's your first problem. Expecting to gain all the knowledge and information you need in one topic. It will not happen so read around some more. Your second problem is expecting people to say "a+b=70000000 hp without voiding your warranty." That won't happen either. And it sounds to me like you have the "the Honda guys should feel blessed I have come to their side" mentality. Well we don't, a lot of guys have Hondas and other vehicles that will run 11s and lower.

Back to the topic, you may think Honda guys just rice out Civics to have a bunch of horsepower by doing loud exhausts and all that other junk. Wrong answer. This stuff is much more technical than you think and a lot of guys are doing full on engine swaps to get the power they want. Not any old Civic engine will do. &lt;No offense D series guys.&gt;

To sum it up this Civic will never be as fast as you want it to be without voiding your warranty. Go buy an old rex, gut it, drop in a built B18/turbo setup and enjoy your new 400 hp Civic.

Sorry - his superiority complex just kind of gets on my nerves.

First off H2290, my whole point is that someone is asking for help and we have members that reply with "go back to your old car" which is no help at all. I'm not saying that he's gonna gain all the knowledge in one topic but that doesn't mean let's bombard him with useless replies.

Second, I don't expect for him to get replies that say "a+b=70000000 without voiding your warranty" because we all know that won't happen. But again, posts that do not deal with topic is what I was talking about.

And Finally, if you could learn to read into what I was saying, I don't have that "Honda should feel blessed I came to their side mentality", where in my posts do you see that? I said unification of CAR ENTHUSIASTS.

So who really has the Superiority Complex?

 

Hey you just may want to check into aftermarket parts that the dealer sells. If I remember correctly there's a dealership here on the southside that sells aftermarket parts. They have stuff like Jackson Racing, Spoon, aem, and other little products like that. Like somebody said before i'm not sure if they are covered under warranty, and probably in order for them to be covered under warranty you'd need to get them dealer installed. But that's just my lucky guess.

good luck
