maybe a proformance chip or a little turbo for now.

posted by  Alpha Lobo

i think turbo will cost atleast 3Gs (the whole kit)

intake!

Spending money on HP is never a waste...just depends on where you want to take the car...if you are going to turbo the car later on...then dont get something you might want to sell later...sometimes things like headers dont retain their value and you'll be stuck w/them or at least not get what you paid for them

So if you are going to stay NA...get an intake, headers, maybe a ECU/chip upgrade...

It'll give you decent HP...but not beyond that of the RSX-S

For the best boost go get a wet NOS system. That'll give you the horsepower you want when you need it.

Thanks Gabriel. so if u think i get all those...intake, headers, ECU
will it atleast get to 210hp?
i ll juss pass on NOS, dont want to pay for it everytime i refill it

posted by  slvracurarsx03

The base is 160hp so intake,headers, and ecu wont get close to 210.

I have a question, why would you need an aftermarket ECU when your puting on intake and header? Would that really help?

posted by  CarEXPERT

yeah, except you have to replace a lot of parts, and it costs close to 2000. But, a 1000 shot system doesn't need to be replaced anytime soon.

that is aloto money, i ll juss stick with exhaust, intake, headers
what do u guys think bout this new supercharger only $70

i juss want to waste not more than $1500
n gain quike 30-40 horses

Intakes are where the K20's really open up when you throw on an aftermarket one. A CAI from Injen or AEM will net you well over 10whp and I suggest eventually getting the Hondata ECU to raise the redline.

The intake, headers, exhaust, and ECU combo will get you about 30-35fwhp

i really dont have aloto knowlegde with ECU's
can someone help me out here???....

Yes can anyone explain why a new ECU would help?

He does'nt need a new ECU, he would just need the one he has re-mapped. "Performance chips?" Meh, unless you're driving something that can have a DINAN chip added to it I doubt a performance chip is going to give him anymore power than a custom fuel mapping. Anywhos....

You have one of two problems. You're driving an underpowered car and you want some serious horsepower gains. You also don't want to spend more than $1500. Well... If I owned a performance shop I'd simply point to the door and tell you to take your cheap ass away from my property. But seeing as I don't have the privelage to do that, I'm going to attempt to help you.

There are some quick ways to get to 210HP with your motor. You'll definetly need an intake, exhaust, and headers. This right here will bring you just to that $1200-1400 mark. After this you'll probably be somwhere arround 180hp ish. You'll either need a very good ecu chip or take it to an Acura performance specialist and have him re-map your fuel curve to get the best performance. This will probably bring you to 200HP, and to get that extra 10 you'll need some higher flowing fuel injectors wich will most definetly push you above 210HP. Estimated price for all of that is $1800-2400. For $1500 I don't forsee you getting any further than 10-20 more HP.

Performance is'nt a cheap thing, and if you're going to spend $1500 on 20 horses with no intention of ever upgrading the car again I'd suggest you save that money. It would be a waste. You're not going to miss those extra 20 ponies, and I'm sure you could do more with $1500. So put your priorities first. $1500 for 20HP or $1500 for a brand new set of wheels or something?

REPLACING YOUR ECU CAN DO ALOT OF THINGS DEPENDING ON THE ECU AND THE MODS YOU HAVE DONE TO YOUR CAR. IT RAISES THE RED LINE SOME ELIMENATE THE REV LIMITER, IT CAN CONTROLL HOW MUCH FUEL IS PUSHED AND DEPENDING ON THE ENGINE CAN RETARD OR ADVANCE THE TIMING. IN MY EYES IF YOU DO ALL THE OTHER STUFF INTAKE EXHAUST HEADER THE NEXT STEP IS ECU AND HIGH FLOW INJECTORS POSSIBLY A FUEL RAIL. BY DOING THE INTAKE AND EXHAUST YOU HELP THE CAR BREATH BETTER SO BY ADDING A TWEAKED ECU YOU CAN THEN PUT MORE FUEL TO IT TO GET MORE HP

I pointed him to Hondata because they test and tune all their ECU's strictly for Honda engines and have made a very nice ECU for the K20. Which not only re-maps the fuel but also raises the redline (much needed on the K20a3) and has shown pretty good increases in power (from 7-15whp pending application). My friend has I/H/E/Hondata on his K20a3 RSX and it went from the stock 138fwhp to 176fwhp. Moves like an RSX-S now.

DSMer, I heard of fuel maps and ignition maps tuning for the ECU but what are they really for? Especially why would you want to tune the ignition if the spark plugs always ignite.
And I thought that only when you have forced induction you need to get an ecu for tuning the fuel map and ignition because more air is coming in.
How would a new ECU help a stock car or almost stock. THANKS VERY MUCH!

posted by  CarEXPERT

The Hondata is a piggyback system am I correct? Does this mean that you just plug it into your stock ECU and it works. How do you tune the rev line to be higher and would it damage your engine cause you are redlining.

posted by  CarEXPERT

they make flashes, programmable ECU's etc...

The Redline being raised won't kill the motor, they test and tune it to find the sweet spot. The stock redline on the k20a3 is 6800rpm and the reflash raises it to 7300. This engine is meant to sing a lot higher than Honda set it at. The K20z1 redlines at 8100rpms.

posted by  thunderbird1100

If you make the rev higher, will you get more power? And how would you make it rev higher if you have the hondata?

posted by  CarEXPERT

Well, spark plugs ignite when the ECU sends the signal for them to do so. The injectors also spray accurate ammounts of fuel at given times when the ECU tells it to do so. By altering the ammount of fuel and ignition timing you can get timing at that "sweet spot" when then piston just reaches its max within the cylider walls and ignites that nicley balanced 14:1 air fuel ratio mixture.

Most cars performance are compromised to meet emission or federal standards. So all you would need to do is figure out the right ECU setting to get that maximum power out of the car. Sometimes an intake is all it takes to turn that Camaro Z28 into a CamaroSS. Engines, nowadays, are very complex and use intricate computers to measure fuel and air delivery. By altering that computer you can change the way a cars engine runs. So instead of giving an engine the juice to jog, you can bump it up a notch and make the engine sprint. Because an engine only goes as fast as the air/fuel mixture will allow it. The more air and fuel you have condensly packed into a cylinder the more powerful the explosion is. So by tuning the ecu you add more fuel and adjust the engines characteristics to give it some umph...

Thanks DSMer :thumbs:

I'm only here to help..

You might not get more power (I believe you pickup a few whp on the k20 Hondata), but you will remain better in the powerband range when you shift.

thanks guys.....
since its a base model i am gonna gonna go with
cold front mount air intake, headers, i already got
cat back exhaust :mrgreen:
