Natural Aspiration At Its Finest

[Mercad]

Hey all, I am looking at buying a '96 RS. Buying a 4G63 model is not an option, and I don't want to slap a turbo on the 420A engine due to cost. After I buy the car, I am doing a complete engine rebuild, so I can put in whatever internals I want.

My question is what is the best way to set up a naturally aspirated engine that kicks butt? What parts should I be looking at as far as connecting rods and cams and valve springs... etc. I have done some research on Crower/Eagle internals and it seems that all those parts are designed for turbos. All I need is a light, high-revving engine and all the aftermarket parts seem to be extra-strong and heavy. Is this assumption correct or are the aftermarket pieces actually lighter than the stock internals?

If anyone has advice regarding the rest of the setup, it would be much appreciated...

I'd like to dispute '4G63 is not an option' because of the extremely high cost of building an RS Eclipse, then having it be extremely slow. Please explain.

I'm buying it for 1500 or less

Bada$$ i like what you are doing go to this site and they have all the internals to build a strong motor, http://www.modernperformance.com/dcx/oneclipse.shtml
as for wieght they should be the same or a little heavier

[JoeWagon]

Well, the cost makes sense for the initial purchase, however... the fact still remains that it's expensive to build a non turbo eclipse... and with $10,000 down the drain you still will be slow. I'd get the car for a daily driver if that's what you want, and spend your 'mod money' on saving for a turbo car or turbo kit (which I still don't like, but it's better)

N/A just isn't successful

Here Merc this is aslo a good place to buy from i know from experience

Trust me N/A is worth it ive seen a honda HB with a GSR motor with nothing but boltons take down an 2001 SS, 2 2g turbo, and an AWD 2g.All standard. All the drivers were good. I dont want to dog on turbos or anything but its like i said an N/A car can be just as fast as any turbo, or supercharged car out there

[Mercad]

Yeah, I know they're good... I'm really not interested in a turbo car. I'm not in it for the speed, I just want a car that runs well in the higer rpm ranges. Thanks for the links, though i'm also lookin' for some technical information like weights of the stock internals and stock spring stiffnesses, just to compare to the aftermarket stuff.

[Mercad]

wow, man... Those are some really nice kits!!! Thanks again!

You're being fed misinformation. If you go put a lot of money into a nonturbo motor, tell me how happy you are with an expensive slow car.

I could care less if you waste your money, I was just trying to tell you how much faster turbos are. Don't take my word for it, the fastest and most powerful N/A 4cyl motors are weak sauce.

you will regret it cuz youll have all that money and probably be up there with a stock turbo dsm, and all dsm turbo cars needs is few bucks put into it to beat your 10,000 n/a car. not tryin to bash on u or nothin but think through it a little more.

turbos OWN everything out ther. but guys, i was talking to a friend of mine, he said someone at NOPI had 270 hp to the wheels on a GSR with a stroker kit, porting and polishing, and some other stupidly expensive motor work... no blower or turbo..was he bullshitting?

[EclipseRST]

doubt it... the GSR's have around 200hp stock, not sure on the exact number but they are quick for a n/a motor, shit they run low 15s!

bclipse... your a moron, there is no way a n/a motor is or ever will be faster than a turboed or supercharged motor! no matter how built up the motor is, forced induction will always be faster!

[firesdoom]

It's just plain physics man. Don't waste your money unless you're rich. If you are rich...this is a dumb hobby you have. But, should you want to spend some money buy me a turbo first cuz it'll cost a lot less than what you wanna do and at least someone's car will be fast.

[bclipse]

People do you realize with those kits he would have well over 300hp all motor, on top of that if he wants NOS he could easily use it all day because of his stronger engine. People stop being ignorant and if an N/A motor is never going to be faster than a turbo or supercharged motor why did that HB spank all those cars including an AWD. Oh and might i add that none of those car were stock

[ashah000]

Do you understand that you're a dumbass When did using nitrous become part of an all motor car. There is no fucking way in hell that those kits will get him even close 300 hp. If he spends $5000 correctly and tunes it right he would have about 200 whp. Get your fucking shit straight before you mouth off.


And STOP comparing a honda to the 420a IT IS A DIFFERENT CAR!!!
