honda speed upgrade

hey, i just got a 1990 honda civic hatchback and i was wondering what kind of things i could do to up the horse power.. for relatively cheap. thnx

IF just want it to be a little quicker do the usual mods... Intake, header, exhaust. Plenty of parts available for the D15 motor.

What's your budget?...I'd suggest intake and exhaust too though...

1. Intake
2. Exhaust
3. Performance computer
4. Pulleys
Might run u a bit over 600 canadian, but itl be noticable.

if you really want to wake it up, do a DPFI to MPFI swap, get a full exhaust system, and an intake to fit the DPFI to MPFI swap. should put you in the 130 to 140 range. not to bad for a d15

I say Superchip her...assuming it's available on this model....should be ok given that it's not too early (as long as it has an ECU it should be ok...which it does have lol)...quite costly, but can improve fuel economy and makes it smoother running, too. It'll add around 20bhp depending on what sort you get!....a mans Mod lol....none of that "K&N" stuff here lol

posted by  Cliffy

More like a chav mod lol:mrgreen: . Something which adds 20hp, improve fuel economy and smoother running-sounds too good to be true?
A real man's mod is to adapt Suzuki GSX-R throttle bodies onto it and try to run it on Megasquirt ECU:hi:

posted by  fudge

Nope, a chav mod is the massive spoiler and that K&N Induction kit (that costs about £65), adding 3bhp! :banghead:

The Superchip improves fuel economy by "modifying" the ignition timing. It makes the car run smoother by playing with the ECU in the same way...and more power too!

posted by  Cliffy

Well if a superchip makes the car more powerful, less thirsty and more smoother then how come car manufacturers don't use their systems? Sounds a bit too good to be true eh?

As you can tell I'm very skeptic that by simply bolting on a chip gives 20hp increase and better economy especially as Honda have spent loads of labour and time trying to get an engine map which has a good compromise.

posted by  fudge

What about new cams, that can't be too expensive, and should improve power, and where it peaks, right?

posted by  chris_knows

That's why Chips are so expensive, it probably wouldn't be cost effective for manufacturers to use them....they are about £300 a time afterall!

I'm skeptical about modifications too.....but onlywhere induction kits and back boxes of exhaustsare concerned...I just dont see the point lol!

posted by  Cliffy

Actually, cams are a pretty expensive mod.

posted by  elchango36

I remember reading somewhere that it would be about $500, and gave pretty good power/fixed the car's power curve?

posted by  chris_knows

It depends on the car and who's doing it for you ($500 just for the cams, not including labor). $500+Labor doesn't seem expensive to you???

posted by  elchango36

It does, but if he wants to spend under $600, couldn't it be done?

posted by  chris_knows

Perhaps, but cams alone aren't gonna do the trick. At the very least you'll need adjustable cam gears, maybe some stronger valve springs, and someone to tune the car after everythings been installed. I don't see this landing anywhere under $800. You can't just throw parts at your car and expect performance. You need to fine tune them to make sure your geting your maximum potential.

posted by  elchango36

I see, but would it add substantial(sp?) power?

posted by  chris_knows

Yep:smoke: It's the first step towards N/A God status LOL!!!!

You need to realise that a chip and a ECU do the same thing, manufacturers won't need chips as they can programme the map into their own ECUs. How a chip can outperform a ECU in most aspects escapes me. You may like to read this article as it'll give you a better understanding about the 2.
http://pumaracing.co.uk/chip.htm


It's been proven that routing cold air or increasing the airflow into an engine increases horsepower and throttle response. However there hasn't been prove(independent tests) that by simply putting a superchip alone into your engine that you'll get all these benefits that they claim.

The reason why I dislike Superchips is that they are marketed to the uninitiated(readers of Max Power and other soft porn car mag) in a way that you can get 20hp by just getting it. I once heard a rediculous claim that a Viper can gain over 100hp with a chip, I mean come on where did Dodge go wrong when they mapped the car?

posted by  fudge

I dunno, I like the viper myself, but it is an 8.3 liter and the block
is originally from a truck (heard it on topgear srt10 test)

it would then have 600hp. which isint all that hard with so much room inside:hi:

theres a thread I started goin on now about 100+hp per liter engines
I think I can believe that:2cents: :2cents:

830 horsepower there haha

posted by  nighthawk

i think when u say chip you mean a replacement for the ECU of the car. There is a guy up in temecula that can reprogramm your ECU to net you a very very large gain, so i dont think it idiculous to see those types of gains out of a simple plug unplug process

but, dont trusts those ones that are cheaper than 100$, those are just resitors put into your maf to trick it in thinking the air is hotter than it is, ro colder, cant rember which way it goes but ya, chep trick that does nothing but hurt ur car

posted by  ride3k

Increases horsepower, yes....but only by about 2-3bhp, if not less, so spending £60 on this is arguably the same as fitting a chip?

posted by  Cliffy

thats very arguable, and totaly dependant on where the new air box is located and what air it gets, how much, etc etc etc.

plus, turbos benefit greatly wiht this simple intake upgrade, more than 2 - 3hp

posted by  ride3k

oh ya, forgot to add, 60 bucks?? just go out and buy a bigger filter, much much cheaper and nets you relatively the same gains depending on your engine compartment

posted by  ride3k

But K&N are an established company and make filters which flows and filter well and can be cleaned and re-used. Even established engine builders like David Vizard tested and reccomends them in his books.

Superchips on the other hand aren't used much in club racing and have yet to prove itself other than in the boy-racer crowd, and with ECUs like Megasquirt or Emerald3d which dosn't require ROM burning hardware to programme into I don't think the Superchip would catch onto the club racing scene.



I don't think Superchip is a replacement, it's probably just a process of wiping existing data off the stock ECU and reburning the ROM chip with their own map. To net a very very large gain the engine must have been poorly calibrated in the first place or that other modifications were done as well and that the engine needed remapping to suit.

I've just seen an advert for superchip bluefin and it claims no mechanical knowledge is needed-very worrying indeed.

posted by  fudge

Superchips need to prove themselves?....they certainly proved themselves with half of the UK Police forces in the 90's. I'm not sure if they use them now for a few reasons, but I know they used to in the late 90's, especially in Traffic cars, and were very impresses with them :thumbs:

K&N rely on a "Boy Racer" crowd, because all Boy racers car about is making tha 3-cylinder Corsa sound like a tank!

posted by  Cliffy

Really? I haven't heard about cops using them. And why haven't they used it nowadays if it had supposedly great results?

[/quote]K&N rely on a "Boy Racer" crowd, because all Boy racers car about is making tha 3-cylinder Corsa sound like a tank!
[/QUOTE]
And yet they still make filters for DCOE carbs and throttle bodies. Didn't think much boy racers actually know such things existed or how they worked.

posted by  fudge

Cops used to use them in the late '90's in their Volvo T5's. I think the fact that they could top 150mph without the chips made them think again about using them. In this situation it was pointless spending money (our money....so it's all good lol) on them if they were powerfull enough already! It was only Traffic cars that used them though, the standard patrol cars (Astra's, Focus' Volvo S40's etc) are completely standard!

As for the Boy Racers. I dont think they're that intelligent either....but Halfords sell books now lol

hmm heard rumours about coppers chippin the cars, not sure wether its just a rumour set out to sell more superchips. Im runnin a 95 civic esi D16z6, got the usual mods header, straight through exhaust, induction kit. Im gonna go the superchip route, only cos gonna get it done for free hopefully monday (its good to do favours!) from what i understand of it, manufacturers have to conform to certain regulations, with regards to emmisions, economy, noise output... and as such they have to compromise and accomodate all types of drivers from your granny to your boy racer, the maps on their ecus should reflect this. sport chips on the other hand dont have to. they can map the ecu to how you drive. i highly doubt the improved economy, admittedly superchips dont claim to increase economy on petrol, on diesels they claim to. But with every hp gain the more frequently i have to fill up. pre mods i got 300 miles to a tank now i get 250 to the tank
