Help building up my N/T

[futzly]

I have a 1996 2.0 L Mitsubishi Eclipse RS N/T. I have about 7-8 grand to work with, and I plan on spending it all on a new turboed engine and all parts associated with it. The thing is, I don't know much about engines and I'm looking for some help on what to do and what exact parts I need to do it. Is there some place I could go to help me out? Or maybe someone in this forum could help me out? I'm located in PA, a little closer to Allentown than to Reading if that helps at all. The key here is I want this engine to be like new, with almost all aftermarket parts on it. If you could help in any way, that'd be great. Thanks, Eric.

Well, theirs a couple things you want to think about.
You could either.
1.) swap motors to 6 bolt 4g63t or 7bolt 4g63t
2.) turbo your 420a
3.) sell yours and buy a already turbo 2g

But I'd say since your in tri-state area, TurboTrix would be best if your looking for someone to do the work for you, They are well known in our area they specialize in DSM's
alot of people turbo 420a's but it also depends how fast you actually want to go. Lots of things to think about when you have a decent amount of money to spend you dont want to do the wrong thing ya know

Thanks for the advice. I forgot to include that my engine currently has 133,000 miles on it. So putting a turbo on it wouldn't really help the fact. Either I could rebuild it and turbo it, or I could swap it with another motor and do stuff with that. I've been told to go with the 6 bolt swap, but I'm not quite sure yet what I want to do, or if thats even a good way to go... I want to learn more about it so I don't make the wrong choice, but I'll try to contact TurboTrix and see what they think. Any other suggestions?

 

[Burnett03]

Best advice i can give you is to use that 7-8 grand and sell the car you have now and get a turbo one.

 

[janks85]

Yea I'd have to say taking the money you have and selling yours and putting that money towards a already turbo one is probably your best option, but like I said in my last post their is alot of people that turbo the 420a and i hear good things, and their is places that sell complete rebuild kits(bottom ends) to turbo a 420a and show good numbers on a dyno. But yes turboTrix will most likely explain alot to you

Don't mean to sound like an ass, but you can't swap a 6 or 7 bolt into a 2g nt dsm.......unless he wants to spend the 7-5g's he has to have the custom fab work done.

 

[janks85]

I was just stating options

 

[futzly]

I think I'll probably rebuild the engine with that kit and then do the rest.. can anyone give me a link for this rebuild kit? And I'm still asking for any suggestions. Does anyone want to change my mind, or does that sound good?

 

[DarkCobraMan]

get yourself a good ole 1g awd just my opinion...but with that money you could get a nice setup to work off of

Then goto build your own engine kit

chris,

 

[futzly]

ok cool, looks good to me. thanks for all your help. now I just have to find someone to do all of the work..

 

[janks85]

Just be careful with your trans, Try either http://www.dogboxracing.com/ or http://www.sheptrans.com

 

[president95]

I was just stating options

But swapping a 4g63 into a nt 2g isnt a "real" option..

My advice; Sell the car, buy a 4g63 powered dsm

 

[futzly]

I'm not really into selling my car and getting a new one.. I've done alot of work to it as it is, then I'll have to do it all over again. So I'm just gonna work with what I have.

Really recommend selling the NT and buying a turbo one to start with. You're going to sink an incredible amount of money into it, and get lackluster results by comparison. Personal opinion, it's a waste of money. No matter how much you've tossed at the car so far, it is NOT worth the large amount of money, hassle, and reliability it will eat. You will have to replace a LOT of parts, essentially rebuilding the car as a turbo model piecemeal.

Then again, no one who goes 'dead set' listens, until they've tried it and are broke, and end up with a car that still gets smoked by a stock turbo DSM.

If you love your car, keep it. Use it as a daily driver. Use that 7-8K to buy a 2G GS-T in good condition, or a GSX if you can find one. They can easily be had for cheaper than that, and still leave you with some cash to do standard maintenence and the initial power or suspension upgrades. Or buy a 1G GSX in awesome, modded condition and still have a few grand left.

I agree and disagree.

It is not cheap to turbo a 420a, but it can be had for $1000 or less, if the kit is pieced together yourself. Expect $2500+ for a kit.

It is a hassle if you are are unfamiliar with engines. It is, otherwise, a bolt-on affair.

While the 420a is not the proven powerhouse that the 4g63 is, it's reliability isn't an issue. 420a's with properly installed turbo's are extremely reliable, with little to no problems, even with no real tuning.

end up with a car that still gets smoked by a stock turbo DSM.

A 420a @ 8psi on the stock bottom end is faster than a factory turbo car.



Pro's to turbo'ing a 420a vs GST: (my opinion)

• Boost leaks are a maintenance issue, not a drivability issue.
• Venting to atmosphere is just how we do it. (that shouldn't matter)
• The design of the 420a's crankcase and head is stout, modern, and more efficient.
• Very reliable.
• Gain a great deal more knowledge about engines and how turbo's work, as you are not simply "turning up the boost" on a factory turbo car, you are pressurizing an engine that was not intended for boost, overcoming several obstacles to make it happen.

Cons to turbo'ing a 420a:

• You are not simply "turning up the boost" on a factory turbo car, you are pressurizing an engine that was not intended for boost. (yes, thats a Pro and a Con)
• The stock bottom end is strong like butter.
• The ECU will fight you the whole way, and cannot be reprogrammed or "chipped", only tricked or circumvented.
• Smaller aftermarket.
• AWD is not an option. No heart-attack inducing launches here.
• 10's in the quarter mile are not likely.
• It's not cheap.

I am sure there are plenty more pro's and con's I failed to list. My advise is to be aware of the limitations, and make sure that it is something you really want to invest your money into, before doing it.

I have a 1996 2.0 L Mitsubishi Eclipse RS N/T. I have about 7-8 grand to work with, and I plan on spending it all on a new turboed engine and all parts associated with it.

This is not at all a bash, nor is it meant to discourage your intentions. But in all seriousness, you would be much ahead to put those kinds of resources into an AWD car, and use the leftovers on its maintenance and upgrades. Turbo'd NA cars can be done, and can be done well. But it can be an involved project for the inexperienced. And when you're done, you still have the FWD's discomfort with traction to deal with.

 

[twinturbo3k]

I suggest JNZ tuning to help you out with your performance goals. They are alot closer to you than turbo trix and have done nice work for me and others in the area. I live about 5 miles from you (assuming your profile is right) very close to Emmaus, and JNZ is about 30-35 min from me.

 

[mjboehm]

I would go on what "defiant" said about just getting an awd car. it is easier to start with the best platform

Well said.

 

[futzly]

I'll have to see what I can find. I just think that buying and selling again would be a major hassle (although AWD would be nice), especially since I will lose a good amount of money in the process. And I'm not necessarily looking for the fastest car in the world, I just want a little more power with good reliability. And from what you've been telling me, it seems like I can get both of those with what I have. Its a tough choice.

 

[DBordersX]

I've got a 2GNT that I'm going to be rebuilding and turboing (over the next few years ) and personally, if i had the resources you have I'd be very tempted to go along with most of these guys and get the AWD model.

Something to think about though is that if you rebuild that engine and do it right (forged internals and all that) then it will have 0 miles on it and it will handle anything you can throw at it. Also, for not that much more than the standard rebuild, you can stroke it to 2.2L and lower the compression to 8.6:1 for more turbo potential. Also, the 420A doesn't have the crankwalk problems that plague 4G63 (certainly not all 4G63's get it, but you have to decide if you're going to risk it on a used 4G63 with X miles on it).

If you sell yours and buy a GS-T or GSX then that motor is going to have miles on it, the internals will be stock, and it's likely that the previous owner was not a member of this site and may not have taken the best care of their car. (I think these turbo guys will agree that a turbocharged car needs much more extensive maintenance than your typical daily driver, there are just that many more moving parts that can break).

I wouldn't sell and buy a GS-T because if you rebuild it right your rebuilt motor will be stronger and last longer than a stock 4G63 with however many miles on it. But the GSX is another thing because there's really no substitute fore AWD. Just my $.02

Good luck with whatever you decide to do

 

[futzly]

Yeah, I think it would be a lot easier to rebuild. I just want to make sure I get ALL the right parts. I might need a new tranny too. But I could use some help on where to get these internals to rebuild.. I was told about http://www.420a.cimotorsports.net/ earlier on in the thread. How does that look for starters?

 

[futzly]

And one more thing.. what should I do with the ECU when I turbo it? Will I need a new one?

 

[VelocitàPaola]

No...
