4G63 Or 420A ???

[talon55]

Ok so I have 2 eclipses (2nd gen.), one has the 4G63 motor and the other has the 420A motor. I am going to hook one of them up and have the other as my daily driver ... what one would be better to hook up ?? I'm looking for maximum performance. Also is one more expensive to hook up than the other ??

the 4g63 will give you better results. and your profile says its a talon awd, so i would recommend hooking that one up to go fast, unless you want to go through the trouble of buying a turbo kit for the 420a and not be able to boost as much as you would be able to with the 4g63

 

[yesItsdsm]

Definitely go with the AWD 4g63 to build. Use the 420a for a daily driver. You'll save alot on gas that way too.

 

[talon55]

oh yea sorry ... this profile is my boyfriends, he has the AWD talon, I have two eclipses ... still hook up the same motor, 4G63 ?? Does anyone know the horse power difference??

 

[timot]

yeah that is a no brainer...4g63 all the way

 

[JamiesTSI]

4g63

The 4g63 comes stock at 210HP.

The 420a I believe is around 140HP.

The 4g63 would be a lot better to build for race. The engine itself can handle boost a lot better than the 420a.

 

[aceofriches]

Its not even a dispute.... 4G63..... ALL THE WAY!

The 4g63's factory internals have MUCH greater potential for holding power than the 420a, and is turbocharged from the factory, reducing initial build costs. The 4g63 also has proven upgrade paths, and more community and vendor support. If upgraded internals are in the plan, they both have the same potential, perhaps the 420a even more-so with the stronger block/main web, and better flowing and more efficiently designed cylinder head. With the 420a, though, the AWD possibilities are out the window, and big power is only being experimented with.

IMO, build the 4g63, and DD the reliable 420a.

Your boyfriend should be able to tell you whats the better motor to build

P.S. - You should make your own profile so we don't get confused.

Being someone that has owned two 4g63's in the past two years and that has a turbo 420A, go with the 4g63 if you want good power out of the box. My boosted 420A has beaten plenty of stock 4g63's and I'm only at the max 10psi with the stock internals. It will be a different story though after I get my fully built 2.2 stroker in it this winter.

Bottom line, 4g63 is waaaaaay easier to make faster since it is already turbo stock and made to handle the boost. However, after the 420A is built with forged internals it's pretty much the same.

 

[gsxeclipse97]

I wouldn't go as far as the same if you are comparing a fully built bottom end 420a to a stock bottom of the 4g63. go with the 4g63 and you'll be much happier with the results plus you won't have to wait as long to be able to use the power.

4g63= 400 or more depending if you want to chance it on stock bottom
420a= some serious problems if you boost it with out know what you are doing.

although the same could be said about the 4g63 but you are less likely to screw that up wih boost.

 

[oldman420]

Lets just say that the 4g63 is meant for boost and is designed for a turbo, which is where you make your power in a 4 cyl. and performance parts are way more readily available for a 4g63. 420a cheap oe parts (same as neon engine), better on gas, and still just as sexy on the outside.

yea i know im making one right now actually, i was just thinking about . and yea he did tell me what one to build, he said the 4g63 ... thats the one he has, i was just making sure because the one in the fast and furious was a 420a, so yea i wasnt sure.

Because everything we see in the movies is true!!!

I remember reading that you could buy everything you needed to make a 1000+hp 420a drag engine from Mopar. So, they can handle big power and at those power levels all 4 cylinders need about the same mods. Err, need to be completely worked over that is

However, 4g63 is the way to go. So much easier to make decent power from the get go, and so much easier to add upgrades to.

The 4g63 comes in EVO's. The 420a comes in neons. Do the math!

Plus the car in the f&f movie even had drum brakes in the back. Come on now. Maybe I'm just jealous because I can't double clutch.

 

[DsmChic19]

Ok well I made my own so im not on my boyfriends anymore ... so yea ...

Because everything we see in the movies is true!!!

Well I know its not all true, I was just wondering. I thought the 4g63 was the way to go but I wanted the reassurance

The 4g63 comes in EVO's. The 420a comes in neons. Do the math!

Plus the car in the f&f movie even had drum brakes in the back. Come on now. Maybe I'm just jealous because I can't double clutch.

What do you mean ???

What do you mean ???

The 4g63 comes in EVO's. The 420a comes in neons. Do the math!

Mitsubishi Lancer Evolutions(all generations up until '08) all came/come with the 4g63 platform that are found in dsms. JDM EVO's I-III come with basically the same drivetrains as dsms.
The 420a engine is actually a dodge motor and is the same one found in all dodge neons. Dodge and Mitsubishi have a partnership and share parts. Hence the name dsm=diamond star motors. The diamond is for mitsubishi and the star is for Chysler/Dodge.

Plus the car in the f&f movie even had drum brakes in the back. Come on now. Maybe I'm just jealous because I can't double clutch.

The green eclipse in the fast in furious is so fake. It has rotors in the back but no brake calipers. That means it has drum brakes which aren't nearly as good and don't come on any performance car. The movie also references double clutching, which is a very slow way to shift and no one would ever doing it while racing. It is only usefull if your syncros are going bad in your transmission.

Oh ok I got you now. Now it makes sense ... Thanks !!

Anytime. Welcome aboard and good luck with the new project!!
