Inexpensive ways to increase horsepower?

Q: What can I do to make my engine perform better?
- A: Unfortunately, the D17 does not respond well to standard bolt-ons or natural aspiration build-ups. Even with higher compression pistons, a high-performance cam, custom intake manifold and throttle body, cold air intake, aftermarket header and exhaust, and head work, you may only see 20 to 30 whp (which really isn't worth the thousands you would invest in the project). Your three "best" options are a Nitrous kit (only up to 60hp shot on stock internals), a turbo-setup, or swapping for a K-series engine.
One thing you can do for a noticeable increase of WHP at an affordable price is to install a Crower Stage 1 cam. Match this with an exhaust system and an intake and you can see an increase of as much as 20 WHP. You do not need to run an aftermarket management system. The Crower Stage 1 cam will work with your stock ECU.

Better off leaving it stock. Use the money for maintenance items.

Re: mods?
like the old saying goes, cheap ain't fast, and fast ain't cheap! more true words have never been spoken about car modding,, I'm working on a vintage Accord, I make all my own parts or source what I can from friends,junkyard etc, and even it's not cheap, thats doing all my own machine work etc, if you need to have stuff done better start scratching off those lottery tickets

Re: Inexpensive ways to increase horsepower?
depends on what your definition of bolt on means, to me taking off a head, doing a bunch of work to it, and bolting it back on is a "bolt on" combine a good exhaust, cam, head work, intake and proper tuning, add in additional fuel delivery if needed, in the form of bigger injectors and pump, depends on what you are making, you can make power, but no cat back exhaust, and intake is going to do anything, you have to increase air flow through an engine, and have the tuning to take advantage of it

The cheapest way to make it go faster is to pay someone to sell it and buy a b/k/h/f series car. But you can save that money and sell it yourself, so that makes it a free upgrade

Re: Inexpensive ways to increase horsepower?
Huh? There's a huge difference between discouraging innovation, and knowing the limits and availability of what's out there. There are legality issues with running older engines, and NO solid information regarding engine swaps that are not already out there. I, personally, wouldn't waste my money investing in a J-swap... primarily because they don't have the same aftermarket support as a K-series engine. I just don't feel like machining everything for the engine myself, just to make it what I want. Also, the power from a K-series, for the weight of the drivetrain, is exceptional.
What, exactly, were you desiring from "outside the box" creativity here? Someone to do a funky engine swap? Perhaps some sort of odd body panel creation? All these sorts of things require money, in a far greater amount then the standardized stuff you're complaining about. Seeing as it is a Honda Civic chassis, it is safe to assume most owners do not have unlimited funds to go hog-wild on their cars and truly create something unique, unless they have tons of resources at their disposal to do the work themselves. Sadly, that's just the way it is these days. A lot of kids don't have the drive to learn a craft, just so they can achieve a goal making something truly unique... so we end up with a ton of people buying knock-off's, stretched tires, and cheap coilovers just to achieve a look that seems most prevalent currently.

A properly done tuned Kswap would cost 2x more than the civic he owns if not 3x. bolts ons don't do jack, building the engine internally wouldn't do much and would cost ALOT. He said "Inexpensive ways to increase horsepower?" this thread has been repeated many times. It's like running backwards in a circle. The cheapest way to go faster in that car would be to pay for an add in the paper and sell it

Re: Inexpensive ways to increase horsepower?
nope, power isnt cheap, I was lucky to have stainless exhaust tubing I could use and bends, and friends who were really good welders, plus I fabricated my own intake manifold, I can't imagine what this stuff would cost if I bought it, actually it's not even available anywhere. If you want to go cheap, learn to do your own work,and your own fabrication, it's the only way you aren't going to pay out the ***

Re: Inexpensive ways to increase horsepower?
I remember when I was the first one ever to run the Crower stage I cam before anyone. Everyone said it couldn't make squat for power for the cost. Those were the good old days.

Re: Inexpensive ways to increase horsepower?
OP if you want to learn to make power on the reasonably cheap, and learn to do your own fabrication, etc, then come over to the dark side with the vintage Honda's, you wont be builing any 500 horsepower motors like some new stuff, but you'll have fun doing it

Or switch platforms to stuff that have forced induction to begin with. How does 60whp-80whp and 70wtq-90wtq gains from a reflash sound? (can range from a free flash to a piggy back that runs anywhere from $200 used to $400 new).

Re: Inexpensive ways to increase horsepower?
thats not the point in the vintage cars, the point is to do it the hard way, anyone can do it with later engines and computers, not everyone can build power the old school way, if you don't get it, you never will

Re: Inexpensive ways to increase horsepower?
What's wrong with a j30a4 or a j32 or even j35? All of those engines easily make 300whp with removal of the cats and ported intake. Add a super charger and they're very quick

Re: Inexpensive ways to increase horsepower?
IMO the only disadvantage is the increased weight of the v6 vs a smaller I4. 300hp all motor is better than 300hp w/ turbo lag any day.
a complete J series engine is only worth like 700$ at most, but a 6speed can be difficult to source and they're worth as much if not more than the engine. But I'm not familiar with the 7th Gen I only like the 5th and 8th, the mounts may be a problem. I'll never understand why the swap isn't more popular, there are intake manifolds that fit the hood nowadays, and exhaust bits that dont cost much and bring out the potential of the engine.
