Well, my friend went on the dyno with his RS-T and made 210 hp and 214 lb tq at 6 psi at the wheels. That already makes the same as a stock GS-T's hp at the crank. So, if you think about, yes I can beat a slightly modded GS-T. I have done it before.

I plan on rebuilding my engine with some forged pistons and rods and then get a few fuel upgrades and I will be boosting around 15 psi, which should equal around 300 whp. The 420a is a more modern design compared to the 4G63. Sure, a stock GS-T is going to make more power right away, but it doesn't take much on an RS or GS to make it right up there with it.

How is it easier to work on a 4g63 compared to a 420a? My RS was much more friendly when wrenching on it. My advice to you would be to build the bottom end. There is no way that you'll be able to keep up with a GST with a 16g. Plus you can run something a bit bigger. Only rods and pistons with some clevite bearings and you're in bidness.

It was just easier for me. But like I said, I had friends who were CONSTANTLY showing me things about them. And I did WAY more work on my 4g63t then the 420A.

your gonna make more power out of a 4g63...because its already built for a turbo. 4g63 parts = dime a dozen. and BTW 4g63 is easy as hell to work on... oh and having a turbo'd eclipse/talon is better because over all the stock suspension ect. is better than an RS. You get more bang for the buck with TSI/GSX/GS-T

What is the difference in suspension between a GST and GS and RS? Only thing different is they have rear disc brakes on a GST. I already have my suspension upgraded anyways. All 4 cylinder engines are easy to work on, it's just what you are used to tinkering on. I find it easy to work on my 420a, but when my friend's bros GS-T was having problems, we could figure it out fairly easily. If you know what to look for in general, it's usually easy to figure out problems.

I guess it's just where you live for parts because down here I can find many parts easily for my car. The 420a was also used in the Sebring and Avenger cars and also some Neon parts are interchangeable.

I'm not here to start a war between 4G63 and 420a. I'm just here to help people out with what they want to do. IMO, a 420a is not a bad engine at all. I've had my car for over 2 years now and over 30,000 miles driven and there hasn't been ANYTHING (knock on wood) that has gone wrong engine wise with it. It has been my best car i've owned. Even after turbo'ing it, she still is kickin.

im not hating on a 420a... im just saying the better route is to begin with an already turbo'd eclipse/talon... that way you can buy other things first other than going straight into a motor rebuild and having to buy a turbo kit... thats lots of $$$. i suppose if he already has the N/A car then maybe it is maybe it isnt. Personal choice.

man a 4g63 is an awsome motor i love gs-t's. but i have what i have and thats what i got to work with. and totaleclips_05 he pretty much out lined what i am doing, forged pistons and rods a total bullet prof re-build is what i am going for. i havent seen personaly a bult up 420a so that is what is sparking my flame for this project! and my GS has all four disc brakes i freekin love it! and if down the road i get board i will try and attempt a 1g to 2g swap! all of my plans are not going to happen at once! i am pretty much geting the basic out line of where i am going to start thas what this whole topic was supposed to be about.

thanks for all of the input KEEP it comein i like hering what people have to say about this topic!

Hey blesi660r, if you check out some of the threads on DSMTuners in the 420a section, a guy just recently made about 450 whp on the 420a with mostly tuning as the major modification. The 420a responds extremely well to boost surprisingly. He also ran a mid 11 I think using stock axles, no LSD, and slicks. He has videos and slips to prove it all. He also ran 16 psi on a stock engine from valve cover to oil pan for a whole year before he decided to build up the engine. So it pretty much comes down to how well your tuning is for your car. He is running a Hahn Portfueler for tuning and his name on tuners is awddynamite.

I wish this guy the best of luck with his build and I hope he does not get dissapointed 5k later and find that he can barely break the 13's.
Good luck.


I'm new to this site, and don't want to come off on the wrong foot but...

Turbo kit: $1500
Built motor: $1200
MSnS: $350
Wideband: $300
Axles: $500
LSD: $1000

Those are all rough estimates based on my knowledge thus far. However, those mods should easily propel the car into the 12's with a fairly experienced driver.(which isn't hard to achieve with a bit of practice.)

I have a 420a-T and am the one Total Eclipse is talking about who put down 214 hp on the dyno with stock block at 6 psi.

Not the 12's unless the turbo kit comes with fuel upgrades(fuel pump, bigger injectors, fuel pressure regulator and some sort of AFC not including the missing link). Than there is the exhaust system you will be needing because the stock exhuast is restictive. Than there is tuning. Good price on the motor build but I don't think you can get a fully built 420a for that price. Maybe a short block. So, honestly how much have you put into you 420a-T to get 214hp and what are your mods.
Have you got a chance to run a slightly moded 4g63t? If not would you like to run one?
