so I love eclipses I know that the 420a is a Chrysler motor and that it would probably be a lot easier to go 4g63. but here is the point if i can get around 300-350 hp id buy a motor and build it up and drop it in. the thing is im 18 im new to tuning and is that much hp gain possible by turbo/internals/bolt-ons/ecu? any help would be appreciated thanks, please dont troll
 
For 300-350hp u wouldn't need to build, forged internals etc , just go with a 4g63t, 16g, injectors, fuel pump, some sort of tuning device (all tho u probably could get 300+ with out) and your golden. 420a is a waste of time and money. This topic has been covered a thousand times before but unless u want to spend cash or prove some point there's no reason to do any of that stuff to a 420a its not ment for it. Hope this helps

The most HP for the $ will come from Nitrous on a 420a.

If the motor is healthy you can spray a 55 shot all day long.
 
I personally can't stand these 420a haters,that basically troll on all the threads involving 420a.
I myself own one and am in the process of a forged build. If you lower your goal to around 250hp, you could do so without opening the stock motor. That's if it's in great health. You could achine that with a small turbo(such as t25), injectors, exhaust, walbro 255,and a 12:1 fmu. If you want to go above that, then you are going to be in the same position as me. Forged rods, pistons, injectors, fuel pump, mega squirt, full exhaust and a decent sized turbo.If you want more details please search the forums. You can find a lot of information and some build logs. They will get you in the right direction.
 
I think the point is this, if your willing to spend the money on all that would be required to build a 420a into a powerful platform then why would you not just save that money and put it towards a platform that is already capable? With a 4g63 you have a much higher ceiling and more that you could achieve. Sure we all have our wants and desires and if you really want to build a 420a into some kind of monster to be unique and different then go for it, but eventually you won't be able to go any further and before you know it with what you've spent for that vehicle, you'd be leaps and bounds ahead if you had just saved and waited a little longer and had a 4g63 platform that you built and put the money towards. Just my .02 cents. Not trying to deter you from doing it, everyone here loves the dsm lifestyle so there is always different strokes for different folks.
 
I'm not trying to bash anyone by my last post. I see it like this, if you already have the 420a and aren't wanting a drag car, then turbo it. If nothing else give the motor a refresh and then boost. Can be achieved for less then a couple grand if you are a smart shopper.
My reasoning for building mine is because it's the last thing my grandpa helped me get before he passed. So it's a tribute to him more then anything. I would much rather have had a 4g63, they are less work to reach high power goals.
To the op. Thee 420a CAN be made powerful but I can tell you from my experience so far, you need to plan to spend a lot of time and money. If you aren't prepared to dump around 5 grand into the motor and tuning to reach your 300+hp goal. Then go 4g63.
 
I'm certainly not trying to bash anyone either. p_o_s_pc I think that's awesome that's your doing that and like I said we all have different reasons for doing what we do. I was just speaking in terms of the finances spent to get to where you'd like to be, because for a lot of us that's a big factor.
 
Patience is probably one thing to keep in mind too. My first car was a 97 Eclipse RS. I also wanted to build it fast and try to have a faster car than some of my buddies. I couldn't afford big upgrades or anything like that since I was making minimum wage and paying college out of my own pocket, so I just went with the basic bolt ons. Until I got hired full-time is when I bought a 98 GSX to work on and have as my toy. It took about 2 years to accomplish this, so just have some patience and think about it really good. If you have the 4G63, I'd put my money on that instead. Good luck with your build!
 
So many of us started with 420a s out of necessity, availability, abundance, etc., but as soon as we were blessed to upgrade to 4g63, we never looked back. Just a few years ago I paid almost 5k for a 420a, and my last two 4g63s bought within the last year were $2500(Tsi awd) and $2000(Tsi fwd), both are in excellent shape and were mostly bone stock. That's KBB value. The fact that you have a 4g63 already answers your own question. Keep the 420 as your DD and invest your time and $ into the beast.
 
well that is what im gonna do then ill put a few bolt ons and keep everything well maintained and just tune my 4g63
 
As for the bolt ons. If you don't already know, a generic eBay intake pipe with a good filter(aem dryflow is my recommendation) provides nearly the same results as a name brand. My "chromeintakes" fit without any problems, for the short time it was used.
 
Like any engine, as far as your skills, wallet, and will can take it. The record last I checked was over 600 hp, but that was a sponsored car with a lot of skill, money and time in it. If you're new to the game, start with some basic bolt ons like an intake and a catback and look into a hahn turbo kit when you get comfortable with what you're doing. Start by doing a compression check to make sure your engine is healthy enough to add power to it though. Last thing you want to do is spend all your money building an engine and then be broke when it comes time to fix it.

If it is, it can take 5-7 lbs on stock internals. My memory is a bit vague, but I believe the 16g that comes with a hahn kit typically produces about 10 hp per lb of boost (other turbos will vary by their size), so at 5 lbs, you will be around 180 hp-190hp. If you want more after that, you'll need to upgrade internals, go to a stand alone ecu, and increase the size of your injectors. You should start looking into megasquirt, a wideband, and the basics of tuning as soon as possible.

If the engine isn't healthy now, start saving your money for a rebuild and plan for forged rods and internals to make it boost ready afterward.

Without boosting, you would need a fair amount of skill to break 200 hp. It's been done, but not by many.

Good luck man, I drove 2GNT's for almost 10 years. Despite all the hate, they are fun cars and I learned more about cars than I ever imagined trying to squeeze some power into them.
