is a gs with a turbo the same as a gs-t?

[jt1583]

same as topic, is it?

 

[EvolvingGST]

1G yes
2G no

1Gs all use the 4G63 engine
2Gs turbo 4G63 engines but the 2G NT uses a 420a.

Depending on how much boost you run. If you run like 7-9psi of boost on the 420A you will safely have more boost than a stock GST/X. Obviously you can safely boost more psi than 14 to the 4G63, but the 420A will require a rebuild for much over 250HP

Actually there is a 1.8 1g

Are they the same with regard to what?

They are two different freaking cars, they're not going to be exactly the same.

hahaha i forgot about that...

2.0 I'm reffering to..

but still no because they have smaller injectors and smaller pumps but I assumed you knew that...

and all of those guys meant interior stuff like seats and stuff... or even the body... but engine wise its like I told you...

 

[kpt4321]

The non-turbo and turbo 4G63's aren't the same motor, so you're not right.

The NT has different pistons, different compression, and no oil squirters.

 

[EvolvingGST]

fine your right

but I think he is talking about the performance of the cars too... so please put your input on it instead of just sitting there with one word answers.

 

[boostedinaz]

No. The motor wasnt intended to have a turbo on it so there are alot of differences. You can make it work with a bigger pump, injectors, and good tunning to keep it from dying, but they are not the same.

the 95-99 non turbo motor was a 2.0 chrysler motor Can handle about 8-10 lbs of boost on stock internals and with forged internals has been proven to hold 20+ with the right supporting mods. The name of that engine is the 420a!

The 90-94 4g63turbo motors come in a 1.8 and a 2.0, they are much easier to convert to a turbo because the parts from a turbo'ed 4g63 will bolt up. The compression is higher and the internals are not as strong as the turboed 4g63. The non turbo 4g63 only came in the 90-94 cars.

The 90-92 is a 6 bolt 4g63 turbo motor. The internals can handle about 400hp completely stock with the right fuel upgrades. These are one of the most praised engines in the DSM community because of the popular 6 bolt pattern.

The 93-99 4g63 turbo motors are made in a 7 bolt style and they can handle about 350hp on stock internals. The 7 bolt models are the ones that have been known to get the dreaded crankwalk.

The 96-99 Spyder cars come in a 4g64 2.4 (i think). They have a little bit more torque on the low end then the regular non turbo 420a motor has. Its only rated at 1hp higher (141 vs 140) then the non turbo 420a. They weigh a little more tho, so they tend to be a little slower from the factory.


Most DSM'ers will put a 6 bolt in their car if they ever have to get a different engine because they are a bit stronger and they dont have the reputation of crank walk.

How so? The stock boost on the GS-T is 12 PSI.

Edit: Oops, forgot 7-9 psi on a bigger turbo

 

[DSMeclipse4G63]

No they are not the same.... a turbo'ed 1g 4g63 isnt the same as a stock 4g63 turbo. Totally diffrent...so is a 420a with a turbo alone its almost like a gst but not.

As far as 7 bolts not being as strong as 6 bolts the only reason we usually swap is for a better flowing head and not have to worry about the VERY VERY overhyped CW.

FNG here, Very confused.
What I have = 2GRS [420A N/T]
What I want = more low end power to beat petty people off the Light.

The thought of owing a 4G63 in my RS is a wet dream. I don't need the high end power. This is my beloved [NON-RUSTED] Daily driver. I don't care about the money or the time. I am short on money and long on patience.

Until joining this forum, I had not even contemplated installing a turbo on my 420A. Now I am rethinking this.
My concern is blowing up the block on my brand new 2nd engine. Again money I don't have.
Being run off the road by aggressive simpleton east coast drivers is not something my pride can take much more of.

I am very attached to my 2G. I want more power in the engine. 4G63 6-bolt, 4G63 7-bolt, 4G64 (???), or turbo the 420A? What is the most LOW END power with long life stability option for me? I refuse to go Single Over Head Cam. I thoroughly enjoy my DOHC!
Again I don't need to buy a GST, or a new car. The body on mine is very close to mint. It has been kept in the midwest and doesn't have the east coast rust rot plaguing most of my car's beautiful sisters.
Body is Banging smoking hot, need engine power to match.

To swap the 4g63 into an RS would be a nightmare. You would probably spend more money than just buying a GS-T.

The only option you would have would be to turbo the 420a up to about 8lbs on a small turbo.
OR
Rebuild the 420a motor with forged internals and have a very solid platform for high boost capabilites.
OR
Sell it and buy a turbo model.

If you decide to turbo the 420a there is no such thing as cheap. Forget the word even exists. You need to do it right and it will be expensive or you will be sorry.

Anyone ever supercharge the 420a???? That would give you some low end power

 

[flawlessTSI]

1g 2.0 fwd on turbo (gs) has totality different clutch, trans and axles as a actual gst. And weaker pistons.

Put here for anyone searching for differences.

Just found another thread concerning forged internals. I did not realize this existed, was an option, or possible. Thank you for the update.
I understand the low end boost is 8 lbs. What does that mean for pressure on the block? Forged Rods? Forged Crank shaft? What is the liklihood that will break my block? I understand that turboing a car is expensive. I get it. How to do this right for the 420A?

Simple- turbocharge your engine with a small turbo or supercharger.

The 4G63 turbo engines are lower-compression than your current engine so it will actually make less low-end power until your turbo spools and you see positive manifold pressure.

This is probably so far out there that its not worth considering, but in my opinion, if you were to consider doing a engine swap, why not pick up an old rusted out 280z with a good engine, and swap it in. Probably about the same amount of work as doing a 4g swap, and the added torque of 2 more cylinders inline. You can find a running one for less than a grand, and the swap involves mostly time and a welder. Just my thoughts....

 

[dalawoi]

theres a couple 420a turbo guys out here. After a fully forged bottom end. My buddies on a hahn super 20g on 15 lbs In the mid 300's for hp and trq. They are exspensive to boost but very torquey

I think this is the way I am going to go with this.
I would like to see mid 300's. I just don't want to crack another block. A full engine replacement was very expensive to endure.

I heard the decision should be bewtwwn a Star and a Hahn.

One suggestion was to go with a small turbo.

From what I read there are Stage 1, Stage 2, and Stage 3.
Stage 1 being the "smallest" or "low end" Spools quckily but has a short duration.
Stage 2 being "medium" run low to mid range, spools slower than a stage 1 but last longer than a stage 1
Stage 3 being the "largest" spools up the slowest but lasts the longest and covers low, mid, and high end.

Is this information accurate?
Do I want a Stage 2 for the 420A?
If I am going to turbo this, I want the most I can without the compromise of my block.
