Whats up guys, im new to this site. I have been visting and looking for awhile. I have an RS and im working on the 4G63 swap. I need to know if my factory wiring harness will work and if i can use my RS tranny. thanks for the help :D
 
RS tranny wont work as far as i know. Dont bother doing that swap, its not a easy swap, not worth it either cause of the cost/work/parts itll take. If you dont do the work yourself or cant get it done for free then its REALLY REALLY not worth it cause of cost, hehe. if you want a 4g63 buy a car that already has one it. Hey but if you wanna do it go for it its just prolly smarter to get a different car, check in the nonturbo forum there might be some conversion stuff in there but its prolly mostly for a 1stgen going N/A to turbo, but there might be stuff, i dunno. That swap on a 2gen is hard cause the 420a setup is sooo much different from the 4g63.
 
The thing is someone is giving me this engine with upgraded turbo and everything is hooked up on it. The only thing stock is the head, i think that is what he said. I figured the motor was goin to be the most expensive thing, now that i have got one for free, i thought i could just go get a tranny. I cant afford the insurance on the GST, plus i was trying to convert my RS to a GST just something i have wanted to do. Tell me what you think, and will the motor fit in fine with the factory mounts. Need help if anyone can help me, i appreciate it.
:dsm:
 
I doubt it will. The main obstacle is the engine/tranny sits opposite in your rs as compared to a turbo car.
 
Alright well if you guys know if there is anyway to make it work, i would like to hear yalls response, I really wanna make this work. I want to blow those freaking mustangs that all over the place. Thanks for the help
 
You could make it work, its by no means impossible, its just gonna be really hard unless you have experience and the right tools and help and stuff like that. since you dont wanna pay the incurance for GST and thats gonna be a difficult swap, just sell that stuff your getting save up some cash and look into a turbo kit and some built internals and youll be fine. cause its gonna cost a butt load to pay a shop to do that swap for you, if you can even find someone that will, so unless you think you can do the swap on your own and have all that stuff i mentioned above i really think a turbo kit is what your gonna want.
 
Alright, so go ahead and take the motor and then sell it for about 3g's and buy the star stage 2 turbo kit. What will i need internally to make that work, and my tranny and everything should handle it correct. Thanks again for all the help man. This crap is making sick trying to get everything in order:barf:
 
what all are you getting that you can sell? so we can help you set a fair price. Your 420a will be able to handle a turbo kit just fine at low boost, i said build internals so you can crank that boost up:thumb: I feel sorta bad for talking you down from the swap, if you think you can do it go for it, i just wanted to bring into light how hard it was gonna be for a less experienced person thats not rich, but i still think turbo kit is best option for you.:thumb: but if it was me i would take the hit from the incurance and buy a GSX, o wait thats what i did, LOL.
 
Alright, well I havent gotten a chance to see the motor, he is bringing the eclipse to my work tonight. Then i will get a chance to look at everything. I just hate to get rid of that engine b/c i know for sure thats its beefed up. Another thing that makes me not want to get a turbo on my engine is that im about to hit 100,000 miles:barf: im affraid that it might go out sooner than other. if i were to get a kit, i was looking at the Star stage 2 kit. When i find out what and all is done to the motor i will let you know. This guy is cool as crap because he is givin me his factory side skirts that i have been lookin for since i bought my car. Thanks a lot guys. later :thumb:
 
So far the guy hasnt said anything to me, the engine is still in his car and i have to wait to get it. I hope this guy keeps his word, but i dont know. Giving an engine away is a lot of money. If you guys find out anything about what i will need in order to do the swap let me know. I need all the help that i can get, Thanks:dsm:
 
There was a shop in West Columbia beside the airport that was attempting this swap almost a year ago. They were called ?something? Motorsports, I forget. I stopped in a few times and everytime I stopped by the swap was fighting them. Almost everything under the hood was refabricated, and all wires under the dash were cut and spliced into. The guy I talked to said never again would they do the swap without a Stand Alone Engine Management System, and it would still be a PITA. The money the kid spent paying for the swap trying to save on insurance, he could have insured a GSX. I would tell you to stop by, but I went to go stop by about a week ago and the building was for rent and vacated.

I'm with Malenko on what he said, "Get the engine, sell it, take that money, get turbo kit and rebuild your engine." Sell everything, call Bill Hahn from www.hahnracecraft.com, buy a turbo kit with a bottom end rebuild, and have fun. Look at his Eclipse RS, it has proven itself as a dailydriver for over a year and ran 11.53 @ 123 MPH. I plan on using a turbo kit from Bill after I get my 2.7 stroker from Howell Automotive, but that a different topic.

Also I was wondering if you have joined CarolinaDSM.com. They are a good group of people and knowledgeable to dsms. I am also tired of feeling like I am the only CADSM member from South Carolina. ~Later

well, not sure about 2G's, but my 1G converion has been running great for almost a year now! did the entire swap last year. engine, tranny, harness, ECU, etc. had less than $1250 into the entire swap.

i have a long long post all about my swap if you like... but i condensed it to this becuase i noticed (after all that typing) that you have a 2G, not a 1G

but i would assume it would be very similar.

i say do the swap! (find a smashed up donor car) and have at it!

good luck!

Id say read the rules last poster...

"Don't give tech advice unless you have first-hand knowledge of the subject. Again, link to the answer and try not to guess the answer to a question. If you are not completely sure about your answer, be sure and state that in your reply. The goal is to not spread hearsay or bad information."


You are way off base. AFAIK 1Gs both run 4G63s with the same motormounts and things of that nature. In 2Gs with a 4G63 it is WAY different then a 2G with a 420A, everything is different. There is tons of fabrication that needs to be done and even more electrical splicing.

If memory serves, 3 people "finished the swap", yeah 3 people ever.
One guy got it to run, with tons of problems, that is until it caught fire and burned up. Another guy couldnt get it to run, and there is a guy now on 2GNT.com that is finishing it, he has been the most successful with a nice walkthrough and pictures and stuff but its far from finished. and required a TON of custom work.

It is better to just buy a turbo kit, or even to follow the standard 4g63 owners reply and sell your 420A car and get a 4G63 powered one.


EDIT: I sounded like a d|ck in my reply, that wasnt my intent, so sorry if you took it that way. Trust a 2GNT owner, the swap is not a good idea

None taken, totally my fault. it was late last night when i posted (sleep deprivation?) and i totally forgot that he would have a 420A in it, and not a 4G63NT such as myself. sorry to mislead or confuse, i should have thought that one through a little more first.

respectfully,

I got a friend who has an RS with a 420a. He bought a turbo from hahn racecraft. It was expensive, but he had the cash. He has a 20g on stock 420a! He drove it all summer long with no problems. He even did a auto to manual conversion. If you want i can get info of the guy who did it for him. This kid has never turned a wrench on his own vehicle. He is a big dork! He has this "underground mechanic" that he wont tell us about. OH yeah, and he goes by the nickname "Race". He was only pushing like 4 or 5 lbs of boost. Hmmm, now that i think of it, he wasn't really all that fast. My stock 1st gen at 15psi spanked him. My buddy and his 95 neon spanked him hard too (cai, exhaust, headwork). But now he sent the motor to slowboy for full engine build, and he got a new kit from hahn, he said something about a 25g?! Anyways, having a fast 420a is possible. It just costs alot. With his motor build he should run a 12....if he can figure out how to drive.
 
there is a guy in the next town with a Hahn Racecraft turboed 420a. he has been having problems with it ever since. running something like 5psi, and i think it is slower than my car BEFORE the turbo motor.

i was NOT impressed after driving it. i think he finally got it running right and sold it cause he was scared of more problems. lost a lot of time & $$. now i'm not sure about the Star kits, but i haven't heard a lot of success stories with Hahn.
 
swap = disaster... thats the bottom line.

i, myself, would attempt a swap if and only if i were:
1) a certified mechanic
2) a master welder (tig, mig, etc)
3) a master fabricator
4) someone with lots of $$$
5) someone with time to waste

all of the above, i am not. therefore, i would never attempt this. If you approach a shop and say "can you swap x motor into y car?" most will say yes before even thinking about what it entails. Insanity... anytime you want a motorswap that requires you to fabricate EVERYTHING, you are asking to pay way more than you anticipated.

props to the guy at 2gnt if he completes it successfully... must be one hell of a quality wrench turner :dsm:
 
i talked to a guy here in AZ that did the swap. He said the total bill was a little over $3700, and he did some...but not a lot....of the work himself.


I say its not worth it...

you can buy a star stage 2 kit for $2800, then buy the bottom end kit for $1000 from www.howellautomotive.com and just get like bigger injectors and a bigger fuel pump...and your running an easy 13 sec quarter mile all day long.

If you do the swap and spend $3700 then your running a mid 14...depending on how much its "beefed up."

I say get the turbo kit for the 420a..

or do like i did.......

buy a 1g awd for the price it would cost for a turbo kit for a 2g non turbo.
 
I just want to say thanks for all yalls help. I still would like to try that swap since it is so rare. The guy that is giving me the motor is also working on it for me for as cheap as he can. Hes gonna work on it when he has time so he said that it would be about a week and half. If any of you guys find out anymore i would appreciate the help.:dsm:

good luck , you'll need it.

as for th eguy on 2gnt that just got it done, well it was unsuccessful and he wasted almost 8 grand to not get it done.

you can do the swap man... only if its under 3G's!!!

I figured out a way to do it for 2,800 but thats my lil secret hehe... If your smart youll find out how... the key in the whole swap is finding cheap donor parts... you can find so many mechanics out there that will do labor cheap. I did the swap to prove some people wrong. But what you can also do now and days is keep your RS and with the 3g's just buy a talon that way you got 2 cars....! Swap is hella worth it when you prove people wrong! if you got any questions just hit me up at the Aim Sn: SolarBlueEclipse I don't post much so hit me up.

Attention anyone wanting to do this swap! Here's what REALLY happened to this car:

1996 Mitsubishi Eclipse GST RS converted to GST Shell For Sale click on more details for info., Alright this is a 96 eclipse rs that was converted to a GST .Selling the car with no motor. Comes with rdora bodykit, and drilled and slotted disc. Car is rdy for a 4g63T motor. For more info contact me on aim: SolarBlueEclipse or email me at [email protected] for more info. or you can call my cell and ask me any question you want. $1100 213-305-7842 VIN: 4A3AK34Y4TE379590

I heard he sold the 4g63 engine a couple weeks ago because it never ran right, and now here is the cut up shell for sale. This is a warning to anyone who has ever considered this swap. Not hating on anyone, just showing the facts. Interpret them as you like, but looks to me like a failed swap, not a successful one as claimed.

wow, sounds like someone told some fibs about there 4g63 swap into there 420a car. I say F that swap, if you want a 4g63 buy a 4g63 car. Granted the 4g63 is a better enigne for a turbo the 420a with a turbo kit is far better then the cost, work and performance of swaping in a factory 4g63 turbo engine.

Alright first of all you got things all wrong dude. I completed the Swap, No my engines not for sale because Im keeping it for the 97 GSX I just bought smarty. Its a 6bolt Engine. This car didnt run right at first but all cars do this with swaps. I worked out the electrical glitches because it was guranteed. The only reason why I did the swap was to prove everyone who ever talked shit wrong. I did it, And I ran it. I got before and After pics. I got videos of the car running while I tune my bov, It didnt cost me 8k like people say it cost me 3k except for me changing my clutch to centerforce for 2 bills. but thats my own taste. This swap was completed I put this down on anything. If you don't got the facts don't talk your bs.. .. and the only reason why I think people think it cost 8k because I told one friend of mine that the first guy who was supposed to do my swap jacked my 3k he was my own family member now the whole forum knows because I just said it to clear shit up. don't come on here talking bs if you don't know. Im the only person that knows my goals, and I did the swap for all of 2gnt.com Im selling the shell rdy for a engine. And Im going to repeat this again Im using the 6bolt engine in my 97 GSX I got a new goal its called madpowa. I havnt sold anything yet cars still complete sitting with a blown headgasket. I got a X now (wheel spin not included). Peace out any of you want to talk anything else that aint true say it to me on aim record the convo then post because I don't post much (SolarBlueEclipse)
