97 GS: 420AT or 4G63T? '???'

[InfiniteGSX]

I got a question to those people who has done both conversions. what was more expensive, or would be more expensive. Installing a 4G63T or Turbo'ing my 420A?

Many people will agree that turboing your 420a will be cheaper then doing a 4g63 swap. Some would go further and say that it would be even less expensive to sell your NA eclipse and buy a turbo one from the factory.

...and then they will be warned by the moderating team


420a+T all the way y0...you could keep your car and buy another with the money it would cost for the 4g63 swap

If you turbo the 420a, be prepared. The stock rods are literally junk. Stamp pressed powder rods is all they are and blow apart easy at moderate boost levels.

I agree with XMasta 100%. Doing a 4G63 swap would require so many resources, it would hardly be worth it.

Think about my situation though... I first bought my N/T Eclipse because of money issues, but now, even with money, I wouldn't want a 4G63. I like the 420A platform much more; sure there are a few less resources for it, but the 420A is quite a capable engine if you take your time, research, and build it up in the correct order.

True, but they're at least good up to about 8-10 psi.

Even with the turbo, and after spending all I'll need to spend on rebuilding the shortblock, though, I've still spent less money than it would've cost to swap a 4G63 in there.

Agreed, after you have a fully built 420a, compared to fully built 4G63, your insurance is still quite a bit cheaper due to the vin being n/t.

So around 10psi is about the max I could push out of my stock engine? If I do this 420A, I'd probably buy my friends 6000 mile new Crate Motor and Tranny for $900 since its all pretty much brand spanking new, fully build that while turbo'ing the one currently in my car... see how long it takes to shatter my clutch which is allready about to go out and then swap over the fully built 420A with the old one..

I've heard that a well done 420A will rock my world. I used to hate that engine with a passion. This one is my 2nd. My first was a Avenger ES. I used to own a 95 GSX but it walked.

I want to throw down some moderate numbers. I've seen people on here put down around 200-225 on a stock block to the wheels...


Besides what DSM Tuners shows for NT to Turbo mods, what websites would be good to check out for Turbo kits, or turbo parts such as manifolds and Intercooler kits?

 

[97eclipsesleepr]

good sites hahn, www.2gnt.com is also agood site i say boost your stock motor, i rub 10lbs on my motor stock but its all about tuning man, making sure to get a good air/fuel mixture, and please make sure its intercooled as well. All these things can be bought from hahn,star,or build your own to make a hell of a good car. as stated i run 10lbs daily but i also try to take it easy on it as well, but as said 10lbs is about the highest you can run safely. check out my stats thats what i got a 10lbs.

Are we really debating this thread right now. I remember back when I was a newbie and I asked this question once, and got one answer: SEARCH. I say this thread and a couple main ones like it need to be made into a sticky ,because the information hasn't changed, has it?

Sure hasn't...Good point Rand. It's definitely all here.

Sorry for not doing enough research. I'm not really a newbie in all of this. This is my 3rd DSM, my first non turbo. My 2nd 420A, and I've allways been a 420A hater. But I have heard that if built right, it could be a great engine. And at this point, I'd really like to just save money and get the same result. I did browse through this forum and didn't find anything that was really specific of what I wanted to know. But alot of threads did answer some of my other questions that I didn't ask because I allready found it out by searching...

So Once again, I am sorry for not doing enough research.

I say keep the 97 stock and reliable. Good efficient car for cruising a dd. Take the money you would spend to turbo it and just buy a 1g awd turbo. Then you would have both. And as most already know, a second car is always need when you have a turbo dsm, whether it be a 4g63t or a 420at.

So true ,I will agree 100% with that statement.



If your on a budget, I too would save your money. Shit goes wrong when you start building any car. Turboing a 420a takes a couple large chunks of money, while modding a 4g63T takes little chunks of money here and there.

 

[XMasta19]

it's all about the good feeling of turboing your 420a though...not having a 1g 4g63 running 13's like everyone else and their mom

 

[rs-t eclipse]

I wouldn't run 10 psi on it all the time. After some miles your car, you well start to noticing little oil spots on the valve cover, then a week later it well be flowing oil out like the mississippi. From the rings going bad. At least thats what mine did on only 7 psi 80k engine.

 

[97eclipsesleepr]

no im not worried i had a tuned very well and my shop said 10 psi they way it is should be fine so thats what im going to run

 

[ddavisaf]

In my opinion 10 is pushing it. 7 psi will keep it reliable.
