I just purchased a 1999 mitsubishi eclipse gs and i was wondering what a efficient way to get this car over 300 hp with very limited funds?
 
i don't mean to be a dick, but on a limited budget and 300hp as a goal i would sell it, wreck it and collect insurace, or whatever to get your money back and buy a first gen.

2g n/ts don't have much for a 300hp goal on a budget.
 
yes well at 16 there is usually very little money available after buying a car for 6000 dollars, wow people are really ignorant, and if you dont have a reasonable reply to this post please do not reply to it.....
 
Actually, his reply is very reasonable, you need to take it easy. What he is saying is correct, you should sell your car, and buy a 1g turbo. You should have enough money left over to buy some decent parts, if you get the $6000 you paid for it. If 300 hp was your goal, you should have researched your options before buying that car, that way you wouldn't have wasted time and money. Oh, well, you live and learn.
 
well thats the thing its not just to 300 hp i would like to get 300 hp but i also will be customizing the exterior as well so its going to be all around..... and its not an immediate thing either its going to be several years before it is complete...
 
No offense man, but cheap and 300hp do not go together with a 420a motor. Either sell it and get a 1g like the others said or just save your money until you can afford one of those turbo kits for it. I would say a good nitrous system might get you to your goal but I have seen way to many 420a's running juice pop their headgasket.

If you really want to keep your car, save your money for a turbo kit and just do your exterior stuff while your saving.
 
That's fine, but you are REALLY going to have to work to get 300 whp out of it. For $6000 you could have bought a 1g with some existing mods, and a pretty nice exterior. 300 whp on a turbo is tough on limited funds, n/t? Good luck.
 
crap for 6000$ you could have bought a NICE 2g turbo with existing mods I mean come on obviously you didn't research at ALL or you would have seen that over 300hp on the 420a is a rare thing and most of the N/Ts that you see around are purely cosmetic or play toys. go on over to www.2gnt.com and look at what some of the people are doing in the turbo/nitrous forums and you will quickly decided that you jumped the gun too early on that car. Personally I would sell it and look around for a 2g turbo either gst or gsx it don't matter. You may have to travel alittle farther but it will be extremely worth it.
 
I'm a n/t man myself, and you are not going to get near 300hp on a budget.... hell you will never see 200 horse unless you get a turbo or are spraying. Sorry you have to face the facts, the 420a is not a power monster to start with, but with proper funds you can have 300 horse beastie. go to www.2gnt.com for a more suitable knowlege base or check out the 2gn/t section here on tuners. What kind of funds are you looking at? Chris( GSgoingfast) has a great tech article about boosting the 2gN/T for about a grand(cheaper than a 3500$ kit) That will get you into the low 200hp range on stock internals, any higher and and you need to build the lower end up to handle more boost, and the fuel system will need some tweaks to get you any higher.

Oh and no we can't swap for a turbo motor(not the same engines), just to clear that up before it gets asked.
Good luck on your project, the 2g's are sweet anyways turbo or not.
 
i was to lazy to read other replys but 300whp on 420a? Not to be an asshole but what have u been smoking?
You can turbo it, but any of the stage 1 or 2 kits from Hahn or Star wont give u 300 horsies at the wheels. If u want more then engine needs to be worked on... its just to much pain in the ass to modify N/A. just get a 1g turbo.

Look at the thread about how much you got your DSM for. Look at how much people paid for there GST, or GSX.

You should sell it, and by a 2g GST, you can find one for $6000, assuming you can turn around and get 6k for it.
 
300whp on the 420A... on a budget man you have no right to be spazzing on people who are saying it's not going to happen. If you really wanted a 300hp car, maybe you should have done some research first. Now you're stuck with an overpriced 420A when for 6k you could have a nice modded awd turbo 1st gen and possibly some extra cash.

I think everyone replying to this thread is missing the point that this is a 16 year old kid. If you're just starting to drive, a 300hp car isn't good for you. Sorry to get all preachy, but it's true. At 16 I don't think anyone has the respect you should have fo a high-end car. I'm sure the 420A slightly modded will be enough for him to get himself into trouble and wrecks with.
 
I completely agree that a 300hp car isn't a good idea for a first time car but it does entirely depend on the person. My ex g/f started driving her 450hp drag car the day she turned 16 but she had been junior dragging for 3 years. I know that I rodded the CRAP outta my first 2 cars (94 oldsmobile cutlass and 96 Eclipse GS) and if I had the power that I have now in my GST I would have hurt myself or others. I do think he got ripped on the price for that car but if he liked it what can ya do ya know its too late now for his mistake. I wouldn't spend any money on the car but wait and save up some money for some other project car to get that kind of power out of like an old muscle car or a 1g turbo. The 2g n/ts are NOT i repeat NOT the platform you want to be standing on.
 
420a to 300hp on a budget huh. I can only think of one way.

Bring on the dual shot and pray the bottom end holds. Not sure how happy it'll be with a 150 shot on the motor, but that's the only cheap way to get it done. Sounds like you bit off more than you can chew with this car and these goals.
 
well this is why if you see someone with the word "rookie" by the name dont be surpized at what they may have to say, cause rookie is there for a reason.
 
Congratulations on your purchase. The '99 GS OZ Edition is a nice car. :thumb:

Live with what you've got and enjoy it. It's not a turbo car, but it's nice. You can add a turbo kit down the line but do you really want to sacrifice reliability for a a few pounds of boost? Three hundred hp is an unrealistic goal for an N/T Eclipse. Buy yourself a good intake and exhaust system and uncork some hp from that 420.

Goodluck.
 
What I don't get is the fact that you say you can put 150 shot and reach close to 300hp on a 420a? So, if you just built the bottom end up then what is so difficult about that? Maybe even add a turbo?

Some people have the mechanics to do so or know somebody who can. There may be 101 reasons why somebody didn't buy a turbo. Doesn't mean they should be singled out as stupid for not buying a turbo car and told they can never reach there goal.

Sometimes I see this site as Nazi towards N/T.
 
Well NOS is one option. But to make 300HP on a 420A, you need a turbokit. That is a lot cheaper than going all motor 300HP. All motor you are looking at over $10,000 worth of stuff in your engine. Turbokit maybe $3000.
 
Slammedo, I agree with you, DSM is a DSM. We still have to help the guy out. This is a newbie section, if you have negative comments to say, just don't post.

Yup. And I agree with it being that way to be honest. I'm not trying to be an asshole, 420a's are good reliable motors, but are not exactly the cheapest motors to build up, which is what DSM's are known for.
 
all motor 300 hp? if i was going to think about it seriously, i would get some high compression pistons, bore it out, stroke it out maybe, clear up the intake and exaust,... cams and springs and valves, and find something to tune it with...but im pretty sure that the aftermarket for the 2gnt's is just complete crap because no one likes them....maybe look for some neon sites...
 
N/T 'modelism' aside, look at it this way. He bought a Yugo for way too much money, and wants it to perform like a built WRX, but doesn't want to spend the cash it'd actually take. Are you arguing that the 420A puts out dramatically less power than the 4g63t? Or maybe the inexpensive factor? Or maybe it's just oversensitivity and defensive behaviour for a purchasing decision, that should take a back seat when discussing the reality of making a 420A push out 300whp for the cost of a few packs of baseball cards. Which isn't going to happen.

Pipe dreams, kid. You aren't going to hit that with a GS without spending more than you would have if you'd just bought a 2G GSX pre-built. Sell it off and get a 1G GSX (and a crapload of mods), or a 2G GS-T. You'll be MUCH happier in the end.
 
Let me tell you a stroy.The kid who bought my 2gnt had wrecked his 99 gs w/stage 2 turbo.The engine was fully built and he spent over 7k just on the engine work alone.he basicly bought my car for the body.He bought my car for 2800.With a fully built 420 + bolt ons,stage 2 turbo kit,lsd street preped tranny he was pullin 265 whp FULLY TUNED.so not to burst your bubble,but your budget went to hell my friend.so lets sum up.
2gnt-------------=2800
turbo kit--------=3500
Bolt ons--------=1000
Built engine----=7000
built Tranny----=3500

all this isht about 17,800

this doesn't count suspension since my car had a nice street setup that he was gonna use(sportlines/agx w/pirelli's 225/50/16 on stockers).this does not include labor charges since he did most of it himself.this doesn't include any visual upgrades at all,bone stock.so,yeah were not hatin,just statin the facts.don't get any of these guys wrong,the 2gnt is a sweet as car,but dollar for dollar,it will always be 1 step behind the 4g63.you should just reevaluate your goals.2gnt sexy car/not fats or butt (j/k)ugly fats 1g.
