i want to make my 420a a supercharged beast. i want it to whine. im not sure what i need and if i need to modify (internals). i know i will have to make an intake manifold and upgrade my throttle body and maybe even the ecu. any help would me great. ideas or even part names!! or if anyone would like to be a part of this project let me know. ive never seen one or even a video on youtube!
 
if your going super charged you will need to upgrade a lot. the ecu will have to be tuned and you will need to upgrade your fuel system, and you'll need to run some type of inter cooler. if you don't want to run a normal type (ie front/side mount)and keep your build on an eccentric side, id suggest a water to air inter cooler. they are a bit more complicated but are also very efficient ,and cool IMO. you will also have to use a centrifugal type supercharger. i know rip mods makes one for the 6g72 and 4g64 but i am not sure if it fits the 420a or if maybe the make a separate kit for yours. it would be very cool to see it done though.
 
The questions you have to ask yourself before going down this path are, do I have the patience and willingness to fabricate or alter parts? Am I comfortable going at this project alone? As you aren't going to get much help on any post you make about this, since it is almost unheard of (not completely), so not many people have any experience doing this. And third, do you have the financial resources and room to wiggle as you enter into a build with an unknown completion list.

These sort of builds are, figure it out as you go along, you may think you have everything you need, but quickly you will start making a new parts list, called the how to cover my loose ends list. If you have all of that, then the best I can tell you is to first start with what supercharger you can make work and then go from there.
 
Thats a sick idea I've never heard of a supercharged 2g before! I bet you'd have to do ALOT of internal engine work to get there, but challenge is what drives us DSMers. Hae you thought about a Pro-charger? Iv'e been loking at those for my Canyon.
 
You don't need an intercooler. My ION came stock with a roots supercharger, no intercooler anywhere that I know of.

If your doing a roots/positive displacement supercharger you will have to build a custom intake manifold and figure out a way to place the wheel inline with your pulleys.

IMO, turbo will be cheaper, more efficient, and a cleaner looking install. All the parts are allready out there. Supercharger on the other hand will be a PITA, Costly, not such a clean install, and 90% of the work will be custom.

Sheesh there was a thread on supercharging an NT not that long ago, Thomas Knight made a kit and there was one other kit(can't remember who made it), its possible. Just now you'll have to fabricate the majority of the kit. There are several different ways to do it, easiest is putting a roots on the intake and fabbing it into the intake manifold imo.
 
Been done, T knight kits are around but very hard to find.. Im not sure why you want to do this, either you want to be unique, which is fine, but it wont be a "beast".. Its not that efficient for smaller displacement motors like ours to use a S/C.. which is why it never took flame.. So IF you want a beast, Build and boost it, IF you want unique and not as fast even tho there will be alot of money in it.. go with the S/C. like said above.. , just trying to educate you on what your getting into. Its not cheap, nor will it be faster then a turbo build with the same amount of cash into it.
 
This would be alot of work as they've mentioned. Not only will you have to buy parts, most of it will be fabrication. If you will be doing the fabrications it will save you money....... if not you will be spending more than what you paid for your car. JUST GO TURBO.

FWIW, you don't need an intercooler with a turbocharger either. There's a point where it becomes necessary with either a turbocharger or a supercharger, though.

Also this ^ Cold air compresses better than hot air so running air that is under 100*F will yeild higher hp then over 200*F at the same psi.
 
thanks for the posts. im doing this because i want to be unique for one. and i believe i can make alot of power. people supercharge their rsx's all the time. so i dont see why it wouldnt make power. i expect to have to spend alot. and i want to do the custom work for it. i chose supercharged ### i have a 3800 gm supercharger layin around since i blew up my impala. i would like to go with an intercooler. but i wouldnt know how to run the piping since the supercharger isnt a closed system. even a procharger is a closed system. ive heard that theres not much to upgrade internals wise but again im not sure.

Pick one Unique, or fast.. regardless on what you BELIEVE.. We have KNOWLEDGE.. which = facts.. If you dont like the facs b/c they dont agree with what you think.. then GTFO:thumb:.

Facts:

1. You wont make much power on a non intercooled setup, as its only good to a certain boost level, which is low. by then ive passed you, gotten out of my , and am proceeding to take your girlfriend.
2. the 38oo s/c is probably way to big, you would have to maybe re-gear some things, and machine custom pullies to get it to work. then again, by then ive passed you, gotten out of my , and am proceeding to take your girlfriend.
3.Yes you can make it fast. For numbers sake, and since you seem a little thick.. Ill give you an example.

5K into a 420a TURBO setup = fast
5K into a 420a S/C setup = not even close to as fast as the 5K turbo setup and again, by then ive passed you, gotten out of my , and am proceeding to take your girlfriend.
*the numbers are not actual, just trying to make you see reason.

So again. Pick 1, go fast (Turbo) or go unique (s/c)

And no once cares about RSX's, they arent fast either... And just b/c another platform does it, doesn't mean it makes sense.. Ive seen a civic with 4 turbos.. how come no on does that on here!?

Lastly, it doesnt seem like you know much about boosting in general, so , IMO, get this idea outa your head, and do some RESEARCH. There is alot to modify besides internals.. If intercooler pipe routing scares you, then your in for a world of road blocks, especially with a S/C route when a good majority is CUSTOM FAB.. this isnt hot glue and macaroni.

Sigh .. another Morales92.. asks for knowledge,then doesn't listen to it..

^nice find. man i could do alot with 3500.. LOL, like blow your doors off and steal your GF..LOLz
 
im listening. and i hear you. i dont mean to piss you off. money isnt really an object to me. i know there is alot of custom fab and hours in building and testing. ive boosted before. just mostly volvos! where theres a will theres a way.

1. its might not be top end power but they already have that without a turbo. but a bigger powerband starting at lower rpm would pull.

2. the sound of a supercharger is so nice.

3. there arnt many people who have pulled it off.

4. i just wanna do something that isnt the norm. i have automotive background and schooling at universal technical in orlando.

heres my plan!!

following the video from the thred posted. thanks again gxssixteen6

make a flange for the intake manifold from the head. build a box from metal to mount the supercharger keeping with generally the same diameters as the stock. relocated all throttle cables and sensors and throttle body to the inlet of the supercharger. install new cams and retainers and valve train. run my intercooler piping and mount the intercooler. tune the ecu. and longer belt and line everything up.

its a very general outline. but feel confident in my abilities and that you wont steal my girlfriend! shes the one who gave me the idea. btw the drives a cobalt ss supercharged!!

so in my curiosity i went on the hunt for a supercharger kit for the 420A. and i actually found one i think this will be your cheapest and best option. its a full kit for the 420A using a procharger type sc. hope this helps
Eclipse/Galant/Sebring/Stratus | I-4 Ripp Supercharger Stage 1

thanks for showing me this. good find.
 
1. its might not be top end power but they already have that without a turbo. but a bigger powerband starting at lower rpm would pull.

It would. but id pull on you, and blow by with a turbo build with the same price tag.

2. the sound of a supercharger is so nice.
so is a BOV.. but its no reason to spend 2x or 3x that of a turbo build

3. there arnt many people who have pulled it off.

Its not hard. there are bolt on kits. so no one cares if you can "pull it off" its not a matter of pulling it off, its a matter or reason..You could do everything custom, or you could buy a kit.. its been done, so theres no "pull it off " factor here.. unless you show it to newbs.. but they are newbs so who cares.

LOL, if theres a video holding your hand, then what are you proving you can copy LOL?

4. i just wanna do something that isnt the norm. i have automotive background and schooling at universal technical in orlando.

do a 420a turbo (in the scheme of things) is out of the norm.. how many have you seen in your area..
do what you want, but when you get beat dont cry.

and school means nothing.. i know more "educated" peopel in engineering fields that are complete idiots at everything they do. all school is, is a piece of paper saying you spent money. I dont have "auto edu" but, i still "pulled off" a 2.4 swap, as well as building every other aspect of the build.. big woop..ya know?

no one is pissed.. just annoyed.

I have the best of both worlds, i drive an avenger, which arnt popular, and its built and boosted, which is even less popular, so i get the unique, and fast aspect ; )

Gl on w.e you do..
 
i still havent seen anyone do it. they sell procharger kits. im talking the real deal supercharger. and again im not worried about how much it will cost. i guess you could say i have a team tho. and all the advise in the world. im goin for it. first thing first is upgrading the engine. its not about how little money you can do a build. its about pride in your work and doing something that people will wonder what i was thinking. glowryder you will see!! but thanks for the boost. you made me decide that i wanna do this project even more now!!
 
LOL.. have you ever seen a 1000 hp lambo? or a quad turbo civic? Just b.c YOU havent seen it .. doenst mean any thing.. Go for it. im putting cash on the "this will never happen" horse.
And i agree, i hate budget builds.. I have over 2K in powder coating alone in my bay.. and im not a cosmetic person if that tells you anything about the quality else where ;)

there ARE 2 2GNT'S running around with a T knight s/c (not pro charger).. just fyi. The one thats still active in the dsm world wishes he woulda went Turbo LOL. but it just collects dust for the most part.

http://www.cardomain.com/ride/3319874/1997-mitsubishi-eclipse

oh man ! and hes in FL to!! there goes the uniqueness LOL

side note, funny thing is i almost wanted to s/c my other avenger on air ride for funzies. mayby i will now.. wanna race?

Real deal supercharger? A procharger is a real supercharger. You must mean you want to do it with a roots type blower, instead of centrifugal.
And to the guy who said his Ion is not intercooled, I'm pretty sure it is, your intercooler is an air/water cooler and it is mounted in your intake manifold after the supercharger.

Still this ^

But in all reality you can do whatever you want to do, however, don't expect a different outcome unless you have a better game plan then getting a "real deal supercharger." This sounds like the same reasoning as someone who buys the biggest turbo they can find because bigger is always better :rolleyes:. Everyone would put more faith in you if you had a plan, what fuel your going to use, what engine management, super charger specs, pulley ratios, are you going to stroke it to get more displacement, compression ratio, ext.
OTHERWISE...
Let us know when you hit low 12's.

im putting cash on the "this will never happen" horse.

:D Glowryder... you are my Oprah
 
Lolz! Id love to be proven wrong as it would be semi unique.. but well .. you already kbow what im going to say.. ( matrix ref LOL)
