Best way to get 200whp NA?
Cheapest way to dyno at 200whp while staying naturally aspirated?
Lets see some of your ideas. |
cobb accessport from MM
catless midpipe and an electric supercharger.... hehe j/k |
AP
high flow cat / midpipe exhaust |
We had a local guy do 205 WHP with open exhaust (straight pipe) and the Racing Beat intake. He's just a freak of nature.
The Cobb Accessport and CAI intake and Catless exhaust is your best bet. Toss in the BHR Yukon Coil upgrade and you should be good. |
electric supercharger... hmmm.... =]
|
intake -- hks, aem, Racing beat with ram
exhaust of soem type -- borla, hks, greddy sr high flow cat -- im a tree hugger! (sorta) cobb from mm stickers! hehe |
I made 202whp on a mustang dyno with just a K&N drop in filter and turboxs header back exhaust!

wich is best cltuch for NA?

Truthfully the stock clutch is fine for stock power. Give the old search button a whirl, perhaps "Best clutch" or "stage 2 clutch". Its really personal opinion... |
cheapest ?
gut the cat get cobb AP hi flow air filter and racing beat duct - remove the screens from the stock intake you are now good to go :) |
i noticed a screen within the intake as well, what is its purpose?

and to answer the main question, you can do 200whp quite easily. first and foremost make sure your engine and its respective components are HEALTHY and within working spec. You'd be surprised how detrimental one coil or spark plug is to your power as well as mileage, etc. So check your spark plugs, ignition coils, wires, catalytic converter and air filter. You can then easily bump up to 200 with a midpipe/hi-flow cat and a exhaust.. so long as your engine is healthy. This car doesn't respond well to bolt ons in terms of price->power.. but small things do add up. Other things you may want to consider are a true cold air intake for high end gains and a reprogramming device such as the Cobb AP to correctly tune the factory tune to unlock any missing power. Best bang for the buck in terms of power/price for this car is a midpipe with a Cobb Accessport. |
First Rule Of Modification - (FROM)
- - - If you don't know an item's function, do not fuck with it. - - - the screen is there to even out the turbulent flow (I know, it sounds counter-intuitive) Removal screws with the air flow meter readings, and disrupts the idle. S |

i ran with only one of the screens when i had my stock airbox. it ran just fine.
|
test pipe, exhaust, racingbeat intake with duct, pulley, and that should get you to 200 or atleast close.
|
buy a mustang?....
|
nobody has mention a lightweight flywheel. Dyno tests show that the mazdaspeed flywheel bump hp by 8. That's not a bad increase for our cars for 500 bucks
This is a great option to do, when you replace your clutch, usually you can have them put it on for no extra labor costs. |
The stock clutch is fine for up to about 275 crank hp. If it was me looking for 200 whp (assume you are around 180 whp stock). I would do the following :
1. Cobb Accessport 2. Racing Beat Ram Air Dust & REVi intake box 3. AP Pulley (not a lot of hp, but cheap & easy to install) 4. RP Super Cat 5. Racing Beat REV8 Cat back exhaust. That will probably get you to 200 wp at the top end. Lightened Flywheel is a good mod, but not really price effective, as install cost is really expensive. |

fujita 4.77 is a good mod for N/A
|
Im just getting the cobb ap, cat or test pipe and k&n drop in and de-wall the intake box and call it a day. prob never get to a dyno though
|
get the turboxs exhaust, it comes with a test pipe.

The Cobb Accessport and CAI intake and Catless exhaust is your best bet. Toss in the BHR Yukon Coil upgrade and you should be good. I made just over 200-rwhp back when I was NA, with a cat. I also had a less than stellar intake at the time (Umnitza) so I think that was holding me back. I would say, the easiest way, is: -upgraded ignition (BHR coils) -catless midpipe (I didn't have this but it helps) or the TurboXS complete exhaust system -AccessPORT -modified stock intake box, or AEM or Racing Beat intake with duct A lightweight flywheel will help, as will the Agency Power crank pulley, but they won't yield anything special. A lightweight fly does do more than just horsepower, though. Also, having a motor with strong compression is the best starting point. If you motor has lower-than-average or just average compression, you'll have a hard time breaking the 200-rwhp mark NA. |
mf'er AP PULLEYS....hmmmm
i was deciding which ones out of all of them.... do the pulleys void warranty? |
My opinion; Drop in some bigger injectors, get a Cobb Accessport, and have it dyno-tuned. I think you could crank out a good bit more power. More fuel + More Air = More Power. Anybody see why that wouldn't work? You might want to get a better intake and reduce the exhaust restriction with a high flow cat or a race pipe.
The injectors are not so expensive really. What I just did with mine, but it is turbocharged, is to drop in two 550cc RC injectors in the secondaries, and put the 380cc injectors into both primary ports. My injectors cost about $89 each. You'll need to pull the upper intake to swap them. Not such a big deal I think. From the factory, on MT model, for each rotor there is one 290cc, and two 380cc injectors. By going with the config I'm talking about, it is about a 20% increase in fuel capacity. |

stupid question if you go catless what do you do with the o2 sensors?
|
Haha wow love how whenever I ask a question in a thread it goes silent. yay...

I was reviewing the Cobb AccessPort will this allow manual incremental adjustments to the Air/fuel mixture, or can you only choose from the allotted flashes already pre-made? Are there any other choices? |
keep it in the cat so you dont have to put it back in if you ever have to swap the cat back in.

Ok I thought about it, I guess you would place the o2 sensors into the new made piping but would the engine automatically make up for the extra outflow? Currently I believe I blew maybe both my o2 sensors due to leaded gas, wasn't my fault (my boss gave me free gas from the raceway). So if I delete the Cats what can I do to save $450+$120 on buying new sensors and maybe gaining more performance or tuning capabilities???? :sad:

OP there is already a ton of info. that answers this question out there... http://i164.photobucket.com/albums/u...earchfirst.gif |
Intake...
It seems like there's a wide variety of opinions on the benefit of CAI, exhaust and mid-pipe. These range from being seen as beneficial upgrades to being bling.
The MM Cobb AccessPort seems so widely advocated for hp boost that I have one on the way. If nothing else it gives an inexpensive way to check and modify the tune of the engine. Right now I'd say the CAI and exhaust are lower on my list. |

Its Easy
Sell the car buy another car hmm .. maybe a 350z ? BAM ! isnt that easy ? |

omg, that Dyno-Boost chips is EPIC! :banghead:
|
yes... amazing quality... funny thing is I know someone around here that ordered one for his corolla S. Haven't heard from him since he "installed" it. hahahahaha

pshhhh. you better save up more than 34.95. You know you can stack turbonators too right?!?!? there's no limit to the power you can have!!!!!!!!!!!!

That adjustable +25 hp device looks amazing, I wonder if it would be compatible with my HHO Hydrogen Fuel Cell kit that I also got off ebay.
|
get an access port, and catless midpipe, 12.7 AFR
should get there, or drop in a bridgeport :D |
NO more worries guys I'm working on a top secret power adder coming to ebay. I'll go ahead and give you a little insight as to what your looking for. It's called the hydronawzsupergogeterdonethingy. I know I know something with that many vowels has to give 50+ whp but even better than that it gives up the biggest boom/bang for the buck you've ever seen. Basically I'm going to atomize the nawz before it gets into to combustion chamber therfore giving you and extra power stroke. I promise the biggest boom you'll ever get out of your motor.

Good effort I guess. :dunno: you did not drop some big injector into a z28..... btw, i would bet the rx8 comp ratio is about the same as the 69 small block chevy.. carb does not = injector. and the 60s cars did not have an ecu. much less a ecu as knowledgeable as ours.. btw,, i cant tell you how many sb chevys i have built.. details are important... hey, but what do i know.. beers :beers: |
