Sorry for the repost. I cant create a new thread in the N/T section.

i have a 1g eclipse gs (4g63 dohc 2.0) i want to increase hp and make my car faster. GOING TURBO IS NOT AN OPTION(not even thinking about it). im not gonna race the car. i just want it to be faster than stock. i was thinking of doing the following:

NGK Iridium Plugs
264/264 cams
K&N High Flow Filters/custom 3" ss/aluminum piping
4-2-1 or 4-1 header custom mandrel bent(which is better? 421 or 41?)
2.25' or 2.5" manifold back exhaust
high flow catalytic converter
Delete Resonator

did i miss anything? any suggestions?

again its a daily driver, i just want it to be faster than stock. Thanks in Advance.

The plugs won't do anything for you whatsoever. The cams will give you the most noticeable bump, but nothing too extreme. The exhaust and filter might give you an extra 10 horsepower. For what you are going to spend on all that you could easily find a complete turbo engine to throw in there or do a stock turbo setup on your na engine.
 
You guys he said NO TURBO..... U do get something from better plugs because there more efficient b.t.w. it's just not a big difference, but you will see it more in gas milage then power. With N/A the trick is to increase flow all together... without going to wild some things you can do are cold air intake, k&n filter, TB ported&polished then do a coolant bypass, intake manifold ported polished, cams lifter springs, hot ignition (put those plugs to work), mandrel bent exhaust manifold to down pipe, 2.5 inch piping from Hi flow cat back, 390cc injectors, webro fuel pump, eprom ecu and get her tuned! Next thing is to reduce all friction on engines rotational mass, run synthetics through your car, delete ac, light weight flywheel, delet power steering, get rid of steel rims and find aluminium stock or go aftermarket. The remove more weight all together like rear seats, replacing front ones with race buckets, take spare out, speakers etc. Once all is done not only will you see a dramatic difference in power to weight but u will have a good start to down the road adding a turbo after these guys hound you to death about it LOL.

have fun in you RELIABLE N/A :)

The plugs will not make a difference, you are wrong there. People recommend a turbo engine because it will cost less money.
 
yeah and i went from 25mpg to 26.5mpg based on take refill after tank refill doing the same trip on interstate 94 for a year. Proven efficiency do your home work. you don't notice power gains from plug by themselves just a little efficiency but after doing all the mods they dang well make a difference.

stop trolling

he said turbo is NOT OPTION, we all understand it's cost effective power but that doesn't make it reliable power either. It's more expensive to maintain and run ### you have to run premium gas.
 
Trolling huh, i spend my time to help people on here day in and out with good information, that is not trolling. Claiming 1.5 mpg extra with plugs is ridiculous. It is impossible to even track something that minor.

You have a few options...

-Blow a ton of money on the NT = In the end maybe make as much power as a 4g63t.

-Leave it stock/unmodified=Cheap, reliable, sell it easier.

-Buy a 4g63t car, they are dime/dozen.

Choose wisely.
 
Iridium is actually less efficient. They are less conductive than copper plugs. The only up side to them is that they last way longer than a set of copper plugs.

I agree with this guy. Seriously....1.5MPG gain by just plugs? I can get 5mpg just from keeping my foot out of it. There are WAY too many variables to even consider that valid.

Respect your forum elders

As far as OP: Honestly, you won't see much. You'll hear a bunch of noise from the cams/intake/exhaust but you won't be going anywhere fast. Which to some people is okay. On a NA car, just an intake and a cat delete will get you the most bang for the buck. If you want more power, seriously look into FI in the form of a used T25 or 14b turbo. It will be reliable so long as you don't ghetto fab the install and keep the boost moderate with proper supporting mods.

1.5mpg....HAH! LOL

Iridium is actually less efficient. They are less conductive than copper plugs. The only up side to them is that they last way longer than a set of copper plugs.

Which is why my X requires them expensive a** plugs :notgood:
 
really... how do you track that??? From my home to work and back is 90 miles round trip and the more you do it the better and more accurate the law of avgs are. my trip consumed 3.61 gallons there and back and now i use 3.39 gallons do the math wizard. 1.5mpg isn't a small amount to track. I respect all ## help and how you go out of your way but plugs do help. so you won't get the most out of a good plug until you add more fuel and spark but there cheap and will be useful more so later on.

Again, iridium plugs are less efficient, they are less conductive than copper by quite a bit, meaning that you are loosing more voltage thru the plug. Your theory of efficiency is debunked. It is non existent. They are less efficient. The iridium plugs do however last longer than the copper plugs.

yeah thats why its tested on a flat straight 45 mile cruise controled trip over time of a year.... VARIABLES DELETED. You may be elders but your getting cocky and acting like you know it all... Guess all those manufacturers like NGK BOSCH E3 DENSO are idiots who should be making one plug. BWAHAHAHA seriously would you guys run Autolites in ## car?

Never mentioned iridium plugs???

Call it cocky, i call it experience. You are acting like you have found something that none of the rest of us know about. In fact these threads about plugs have been happening on this and other sites for many years before you even had a car, and always come to the same conclusion. You are just the latest to make the claim.

The original poster is looking to make more power, not get more gas mileage, your so called information is in no way helpful, if it was correct.
 
The development of noble metal high temperature electrodes (using metals such as yttrium, iridium, tungsten, or palladium, as well as the relatively high value platinum, silver or gold) allows the use of a smaller center wire, which has sharper edges but will not melt or corrode away. These materials are used because of their high melting points and durability, not because of their electrical conductivity (which is irrelevant in series with the plug resistor or wires). The smaller electrode also absorbs less heat from the spark and initial flame energy.

just thought i'd help with you iridium argument even though I don't run em :)

Your claiming that after all of the said mods are performed that plugs don't make a difference. So check out any tuned ride with money dumped into it and let me know how many run stock plugs mmk.

Heat range


Construction of hot and cold spark plugs - a longer insulator tip makes the plug hotter
The operating temperature of a spark plug is the actual physical temperature at the tip of the spark plug within the running engine. This is important because it determines the efficiency of plug self-cleaning and is determined by a number of factors, but primarily the actual temperature within the combustion chamber. There is no direct relationship between the actual operating temperature of the spark plug and spark voltage. However, the level of torque currently being produced by the engine will strongly influence spark plug operating temperature because the maximum temperature and pressure occurs when the engine is operating near peak torque output (torque and RPM directly determine the power output). The temperature of the insulator responds to the thermal conditions it is exposed to in the combustion chamber but not vice versa. If the tip of the spark plug is too hot it can cause pre-ignition or sometimes detonation/knocking and damage may occur. If it is too cold, electrically conductive deposits may form on the insulator causing a loss of spark energy or the actual shorting-out of the spark current.

A spark plug is said to be "hot" if it is a better heat insulator, keeping more heat in the tip of the spark plug. A spark plug is said to be "cold" if it can conduct more heat out of the spark plug tip and lower the tip's temperature. Whether a spark plug is "hot" or "cold" is known as the heat range of the spark plug. The heat range of a spark plug is typically specified as a number, with some manufacturers using ascending numbers for hotter plugs and others doing the opposite, using ascending numbers for colder plugs.

coppers better huh?

Actually all the big power dsm's out there are running copper plugs usually 1-3 heat ranges colder. The best plug to make power is a copper plug. Bpr7es and Bpr8es are what the turbo guys run.
 
Geese leweeze, who cares? Listen op. Get your recommended factory spark plugs. CAI, exhaust. Etc all are listed above. I reckn everything (such as flywheels and headers ) would work from our cars to yours. It may cost more and b slower, but at the end of the day this is your car. Im not here to push a turbo agenda (like you said..., NO TURBO) BUT alot of little things here and there will make a huge difference. Premium gas kinda helps. I don't run premium in my crotch rocket only if I can afford it ;).

Good luck man. At the end of the day do what you want to.

And remember.
Don't feed the trolls. Not like anyone here is doing it.

Cheers. Il drink a PBR TO THAT!
 
U do get something from better plugs... it's just not a big difference. With N/A the trick is to increase flow all together... 390cc injectors, webro fuel pump, eprom ecu and get her tuned!

Op asked about HP increase and you suggest plugs?
What will bigger injectors and an eprom do on a N/A 4g63? What is a webro?

To the original poster:
Make/buy a cold air intake, buy/make a slightly bigger exhaust (2.5 in max on n/a), buy an underdrive pulley, replace/repair engine mounts with poly inserts or weld them solid, buy a nice set of tires (will honestly net you the greatest gains in driving experience). Do this and see how much better your car feels.

Other misinformation: premium gas will do nothing but leave him "broker", if the stock ecu is not set up to run on higher octane it will net no gain at all.
 
Old time drivers would find ways to increase the plug voltage up to 75KV to get that hotter spark from a stock plug in as well as larger carburetors to get more fuel in when they cammed the motor ... and it all worked very well.
You got some serious power from normally aspirated configurations.

Who heard of turbos back then - just superchargers driven by the motor itself for the rich stock car set.
 
Turbos have been around since like 1905. And on cars since 1961. A quick google search,....... but what do I know? I am misinformed thinking premium is better for any engine. LOL

DFTT

Really. Walbro? the last thing you should be attacking is his grammar. Im no english major, but I am pretty sure we know what he meant because of the two words after that. =fuel pump?
 
I am misinformed thinking premium is better for any engine.
..depends on the application - you wouldn't want to use prem fuel on a stock VW flat four motor, would yas? :)

Okey, so I forgot about the turbo Chev Corvair of 1963 ... nothing too fancy back then, but gave that flat six a bit of a kick...
