all help appreciated

[95itchypsy]

hey all....just another newbie here. the speed demon has reared it's ugly head again and i am looking at tweakin my 95 eclipse. since this is my first venture into computer controlled 4 banger any hints along the way would be GREATLY appreciated. as for the car it is bone stock except for cold air and a fart can ( gotta admit it sounds cool). it has 122k on the clock and still runs strong so i am gonna start by pulling the motor over the winter and get started. i am thinking turbo with an SDSefi system for starters but the question is what compression ratio and boost should i shoot for? i have decided if i'm gonna do this i'm not gonna half step. once the motor and tranny are done then i'll work on the suspension. so there you have it guys lead me into the world of building a rice rocket. don't be shy......what would you do if the ball was in your court?

Heres a good mod, sell it and get a gsx

Quite honsestly, and with all respect, I'd put the money and effort toward a factory-turbo'd car. Or, if you just want to mess with one endlessly, get one that someone else has already modified. Yes, you can do nice stuff with an NT, but without turboing it, you'll never attain the bone-stock performance of a turbo.

 

[95itchypsy]

your are correct....i plan on pulling my motor and putting a turbo motor in it's place...that is why i asked if anyone knows anything about SDSefi....the site is www.sdsefi.com from what i read it will directly replace the ecu. don't know for sure that is why ask the more knowledgeable folks. thanx for the input

 

[blcknspo0ln]

dude you're missing the point. defiant is saying that with ALL the money you're going to spend building, stroking, whatever to your 420a motor; it will never have the modding potential of the 4g63 motor. [ no debates please ] this is of course you dont spend gobs of cash into building the motor.

basically, you're already spending 3-5k [ depending on your setup ] just to keep up with a STOCK GST. or you can buy a stock GST and spend 3-5k and run 12-13's all day. its really up to you what you want to do.

oh, and if you're planning to do a nonturbo 420a swap to the 4G63T, why not just sell your nonturbo and buy a factory turboed car?

there have been many debates on this.. just hit the search button real quick

 

[sonicnofadz]

yeah the naturally aspirated 420A engine is not worth buidling up. This very same engine is also found in the stock dodge neon (giggle). In my opinion (and in popular opinon) this engine is inferior to the 4G63. Plus it way too costly to try to swap in a 4G63T, it would be cheaper to sell the car and get a turbo car (the engine bay was not designed for a 4G63 engine or tranny). Good luck.

sorry guys i didn't know i was going to invoke sooooo much criticism when i posted my plan, however isn't that what being an enthusiast means....making something from nothing. YES...of course i could go out and buy a car ALREADY done up but wouldn't that take the fun and meaning out of being a car enthusiast. my last project....many years ago...took almost 5 years to get it to what i had pictured in my mind. i thought that i was looking for advice from the ones that had been there....however it seems that what i am hearing is that noone here has ventured into the difficult task of a total transformation. and yes it will probably take ALOT time and money but to me that is the best part of it all....try something, if it doesn't work then try something else till you find what does work. ANYONE can go out and BUY a fast car but few can build em. i prefer to be able to tell people when it is all said and done that I built it myself. i apologize if i offended anyone that is not my intent. back in the day you built what you had because you couldn't just go buy something to replace it because the guy that you just lost to wasn't selling.

You don't have to buy a car that is already fixed up. People are just saying that if you are looking to build a performance car it's best to start from a good foundation. If you were to get a STOCK turbo car there is a much better potential there than what the 420 has to offer. It's going to cost enough time and money anyway even with a factory turbo to make an awesome performer why set yourself back even farther? Start with a good platform and build up from there. There are still many unmolested stock turbo cars out there to build into your own street blazer. Hell I picked my car up bone stock from the original owner with 65K miles on the clock. Save your money and pick up a better foundation to build upon

 

[ECLIPSE90DSM]

not trying to cause a war or anything. but i have to admire what you just said. And your right its about tuning what you have. I do agree that the 4g63 is much better but modding what you got is really the fun part, however if i myself were gonna spend that much money to mod something I would indeed myself go with a 1st Gen DSM with the 4g63 due to the fact is nothing like these other cars and frankly you can go in numerous directions. but if what your wanting to do is mod what you have, I fully respect that and hats off to you. btw keep me posted Id love to see it go really well.....
good luck!!!

 

[uh-oh]

IM GETTING SOOO TIRED OF PEOPLE TALKING SHIT ABOUT THE 420A...if you are capable of building a kit and assembling a motor i will guarantee 12s from $3200...I have 23psi on my 420a now and i dont even have $4200 on it yet...ANY GST that wants a piece of me i am located in Coral Springs (10 minutes from Fort Lauderdale,Fl)...and if your a GSX and really feel like getting beaten, come for it...as long as your on street tires ill run you...if you think you can take me and you run on slicks you can run my teams track car (10.3 on a 420a)

 

[Defiant]

sorry guys i didn't know i was going to invoke sooooo much criticism when i posted my plan,

It's really not meant as criticism. But you did ask. When you do that on the web, you shouldn't have any thin skin exposed.

however isn't that what being an enthusiast means....making something from nothing.

Well, with emphasis on the making. Which usually means, for instance, that in order to build an engine, you don't start with plywood.

YES...of course i could go out and buy a car ALREADY done up but wouldn't that take the fun and meaning out of being a car enthusiast.

Not at all. You could look forward to many years of learning why the last owner gave up and sold it to you. And just maybe you're the one clever enough to make it work. Or, just stubborn enough. Like trying to make a 420a into a performance car, for instance.

my last project....many years ago...took almost 5 years to get it to what i had pictured in my mind.

We envy your wealth of time and resources that enable you to commit such acts of devotion. I miss having mom do my laundry.

i thought that i was looking for advice from the ones that had been there....

Erm... that's what was being given you.

however it seems that what i am hearing is that noone here has ventured into the difficult task of a total transformation.

Not at all. Many have. And when finished, were much more intelligent than they were when they began. And usually don't try such a task again.

and yes it will probably take ALOT time and money but to me that is the best part of it all....try something, if it doesn't work then try something else till you find what does work.

Lovely, have at it. If that's what you enjoy, best to you.

ANYONE can go out and BUY a fast car but few can build em.

Few can even keep the fast ones on the road, let alone alive.

i prefer to be able to tell people when it is all said and done that I built it myself.

Well, some people set records for jumping rope or playing hopscotch. Do what you like.

i apologize if i offended anyone that is not my intent.

I don't think anyone was offended apart from you, from the sound of it. But you did ask. Even after divulging how cool your fart can sounded, and in response to your request that we not be shy, we answered. And, we were uncharacteristically kind about it. So now what, we're all full of shit because we know a little more about this "computer controlled 4 banger" than you do?

back in the day you built what you had because you couldn't just go buy something to replace it because the guy that you just lost to wasn't selling.

Buster, you haven't had enough days to be able to say any of them were "back in". If you had, you'd not have gotten far enough along the 420a path to ever pose the question of getting serious performance out of them.

But truly, all good luck to you.

What the hell, one guy even made an airplane out of a Pinto.


Although it did kill him.

 

[uh-oh]

Im not saying the 4g63 is a bad motor...Ive had 3 gsts and a gsx...im just tired of people telling newbs that the 420a is not worth it..it is a VERY capable powerplant and a good plantform to learn on...much because it isnt as sensitive of tuning mistakes as the 4g63...all im saying if someone with a gs or esi asks what to do with there car the first answer should not be sell your car

 

[97GS-TSpyder]

i dont think he was saying that really....just that its not a good idea to start on one....if you refer to a 4 banger as computer controlled, nad then also make a comment about a welded exhaust.....i think you mikght wsant to start with the whole factory turbo thing so you know how it works and operates before building one from scratch....ya know

ok let me start by answering a few misconceptions....1 it's not thin skin....i actually get a laugh out of some of the suggestions....2 i am full aware of what i am getting into, the reason i want to keep the car is because of the factory color. mitsubishi calls it biscayne green and PPG calls it tri color pea...a mixture of three colors which mitsubishi only offered in 95...3 yes the muffler does sound cool....not as cool the rumble of a big block but cool as it is...4 BACK IN THE DAY....i started turning a wrench on motors in 73 on my first car, a 66 galaxie 500 and since i was born in 58 that would make me 15 then. i have built a couple of chevelles and a 69 roadrunner with a hemi, so I remember back in the day. when i stated this was my first venture into a computer controlled 4 banger that is true, however i forgot to mention that i was 46. just imagine what we could have done back then with the technology of today. back in the 70's if you ran 14 secs you were the fastest guy in town. now it's not uncommon for people to run 12's. it was assumed that i was a young guy trying to get a rise out of others who have been in the trenches for the past 10 or so years tweakin eveything they can get out of theses mighty powerhouses, and that was not the case. i haven't been doing any project cars since 85. i'm having a house built with an oversized garage (that was my only input, ol lady had the rest) and with winter coming on i thought it would be fun. so that being said if i torqued any one off....i apologize. i am staying with what i have and working with that. the plan still stands with putting a turbo on it, if it takes 5 years and 20 grand then so be it. i appreciate all the comments and any info the you all feel to post. thanx and god bless you all alex

 

[Defiant]

i forgot to mention that i was 46.

Whippersnapper.

Oh, and on the 420a: It's a terrific motor. As motors go, perhaps a better one than the 4G63. But you just can't get one to catch up with a 4G63T, and if you're going to be working on an engine, why not start on a higher step?

Whatever. Have a good winter, and please do stick around. Show us what you get up to.

 

[Slipstream]

Buster, you haven't had enough days to be able to say any of them were "back in". If you had, you'd not have gotten far enough along the 420a path to ever pose the question of getting serious performance out of them.

:laugh: That is the best thing I've read in days.

However, in regards to your project 95itchypsy I wish you the best of luck, there is no shame in the 420a. While your build up will be long and painful it is a path that was beaten long ago so there are those around here who can help you achieve your goals. I'd suggest taking a peak at the tuning guide here if you haven't already: Tuning Guide For the 420a. Good luck on the project and keep us posted.
