Biggest engine swap for 2g?

[vtown661]

Im planning on getting a turbo in a year or two but I want to upgrade my engine first because I dont think my 420A can handle a powerful turbo. Im a newb here so if someone could let me know what the biggest most powerful engine I can fit in my 98 eclipse gs is that would be a big help. Also is it at all possible to fit in a twin turbo if I took my entire engine apart and squeezed everything in? This is probably a rediculous question but I have no idea so I thought Id ask. Im hoping I can get a 6 valve DOHC twin turbo but im pretty sure thats out of the question. Let me know. Thanks.

I'll assume that you meant cylinder, not valve.

There are many routes to go if you are planning on tearing your car apart and building it up, but the most common answer you will get is to sell your car and buy a turbo car. Why, because of the expense of doing an engine swap. Say you bought your car for $5,000 (I don't know what a N/T would actually sell for). You would then either be looking at a 4G63T (2.0) or G4CS (2.4L, bigger) swap. I know that a 4G63T with the harness and ECU will run you $1500-2000 + shipping. Then you have to do countless hours of work taking out the 420A, and putting in the 4G63T. Then there are all of the 'you can make it work' compatability scenarios that you have to wade through, just to arrive at a car that probably won't be quite as good as having a car that came from the factory with that engine, and all the subsystems that go with it. I know most of the years had better brakes, suspension, etc. for the turbo cars. By the time you are done, you could have sold your current car to some kid who has the same current aspirations as you do, and just buy a turbo car. Then you will have the option of buying a GS-T or GS-X.

There have been 420a to 4G63(stock turbo engine) swaps done, but the general consensous is it is not worth the time or money. The 420a is a very capable engine, if you look here

you can see others who have turboed them.

There are not any other common swaps except the 4G64(2.4L 4 cyl) bottom end swap that is equivalent to swapping in a 4G63 (see above). If you really want a 4G63 it is cheaper and easier to sell your car and buy a turbo car.

You can do anything with enough $$. But realistically it is just not worth it, why would you want this big bad ass twin turbo enigne in a FWD street car?

Yes I understand that buying a turbo would be faster, easier, and cheaper. But ive put too much money into this car to sell it. Plus its MY car. I dont know just something about it. Its my first car and i bought it with my own money and have taken it apart and dynamatted the entire trunk and cleaned it and installed parts, ect. So I am keeping this car for atleast 10 years no matter what. Im planning on rebuilding the entire car over the years. New transmission, suspension, rims, tires, engine, turbo, interior, paint, cooling system, exhaust system, ect. I know ill be "wasting" thousands of dollars and hours but its worth it cause its a hobby and its my baby. Plus I am gaining knowledge about my car and mechanics in general. You can not put a price on that. In 5-10 years this car will be completely redone. Its almost like restoring a '69 mustang but a '98 eclipse haha. I just want to have something no one else has. Like a 6 CYLINDER (sorry im dumb) twin turbo eclipse. I was just wondering if it was at all possible if time and money were not part of the equation. I was even thinking about making my eclpise RWD but I would need a longitudinal engine and I dont think that would work. I dont want to know what the usual swaps are. I want to know what the best possible swap could potentially be if someone had the time, effort, patience, and money for it.

A six cylinder swap is easier into a car that had a 420a in it.

Its been a few times before.. You use a chrysler six....

 

[selmerguy]

wow!!!!!!!!!!!!!!!! if money and time means nothing then heres what to do. strip down the whole car and spoon it out for rwd. then cut out the fire wall and move it back about a foot and a half. squeeze in a dodge viper motor and tranny. supercharge it. do all the custom work to make the thing work. and then my friend you will have something that nobody has.

2g eclipse 5000, viper motor, 5000, custom tranny 5000, all the ridiculous work and time spent making your car into a monster that not even god could keep up with, priceless

Ok, Forget the Rear wheel drive becuase it won't happen. The most efficient and powerful setup you can run would be a 4g63t with a big single turbo instead of your twin turbo. As for transmission get a shep racing trans with a limited slip since ur FWD. The swap is not that hard to do. It's actually pretty simple. I've done it 3 times now. I've seen alot of built of FWD cars do pretty well, but not matter what you do you'll never catch the traction and launch like an AWD will. So if your thinking about running some great times it most likly won't happen with that fwd. If your looking to have a nice fast highway car that's custom then build up ur fwd with a 4g63t. Just my opinion, hope this helps.

Pss Any thing can fit with cutting wheels torches and a welding machine...

Thanks everyone for your comments....well thanks to some people. Others were not so helpful but I was expecting some replies like that, this is kinda a rediculous question. Anyways, jasoncitrano, wont one big turbo only help highend torque? I wanted a twin turbo (one smaller turbo for low-end, and a big turbo for high-end) for a full range of power. One thing I forgot to add was the car needs to be street legal(for daily driver). With all the money going into the car I wont have money to afford another one. Now I can borrow a car for a while wile work is being done but I dont want to cut into wheel wells and stuff.

These engines are not efficient at spooling two turbo's at all. You would need alot of money and time and think about it, you would have two cylinders spooling each turbo creating an insane amount of lag as opposed to all four cylinders spooling one bigger turbo. It's more of where you want to make the power obviously a smaller turbo is going to give you that quick power on the line and the bigger turbo a more powerful boost at high RPM. One thing I think about when tuning a FWD car is that it almost benefits you creating some turbo lag becuase then you don't spin the wheels right off the line. Then again with a bigger turbo once you hit boost (i've even seen it happen through 4th gear) you can spin the tires. The most reccomended swap would definitly be a 4g63t though. I've driven these engines for a while they are alot of fun and more then the amount of power can be created then what you will need. If your looking for a fun, fast, somewhat fuel efficient engine then it's it. Do a bit of searching you'll see all the threads about twin turbo's...and why not to do it if you need more explanation. That guy had to be totally kidding about the wheel wells and shit do not do that. If swapping the engine is not a possibility for you then i've also seen some fully built up 420a engines as well.

Yeah i didnt think the 420A could run two turbos thats why I was thinking of swapping for a 6 cylinder. Bad idea?

If your thinking the avenger/sebring engine it's junk. Try and find somebody with a 1g or a 2g fwd with a 4g63t and ask em for a ride tell em ur thinking about swapping. if they have a little bit of mods they will change your mind. trust me.

 

[keymaster]

If you want a V6 twin-turbo, get a 3G. I $#it you not folks, here's the link. So, sell that POS 420A, buy an even crappier 3G GT, and do what that guy did.

 

[selmerguy]

you can make your 420a fast too. the hardest part is fuel for high boost. if you are going to do a 4g63t swap just buy a car with that motor in it and save some trouble. (money is no object) then you can work on that car and drive your nice 2g while you work. shoot if money was no object for me then i would have 10 cars. one of those would have to work right?
