Any advice for next mods??

[OneSlowEclipse]

I need some advice as to what to do next. Listed below are my current and mods that are on the way in the next couple weeks. Keep in mind this is my daily driver so it cant be down for very long. Its also needs to pass emissions!!

99 Eclipse GS
AEM Short Ram air intake
H&R Race springs
Tokico blue shocks
Greddy EVO cat-back
Energy Suspension motor mount inserts
B&M short shifter
Ordered and on its way: Bored TB and underdrive pulley

ah....a lighten flywheel and a better clutch?!

Ummm befor drive line upgrades... i would go with a set of spark wires to help burn better, and a larger throttle body, a afc would not hurt either.

[OneSlowEclipse]

I have magnecore wires, im waiting on my replacement throttle body so i can have mine sent out to be bored. To be honest I dont really know what an AFC would do for me, have heard a lot about them though.

[Super Talon]

with the assistance of a digital o2 meter, and a egt guage you can use the afc computer to lean out / richen up your intake to help free up more accessible hp. You have 8 rpm brackets you can adjust at any rpm you want, for each high and low rpms. Every thing is adjustable all they way to what is low rpm and high rpm.

How does it work...

It intercepts the mass signal and either speeds it up or slows it down to fit the settings you set. There for making your ecu think the engine is getting more or less air and sending in the approiate ammount of fuel for that ammount.

[Super Talon]

Oh and just so you know the biggest bang for buck mod out there for nt's is UDP and all adjoining pullys, this frees up rotating mass, and slows down all of the accessories. For a turbo car this only frees up about 1 hp but to a nt it frees up much more. And you will see the difference.

[BoostedGS]

Okay, being one of the only other non-turbo...umm....make that 420A powered cars on the list, I can share my upgrade path.

I started with an intake, header, exhaust, 8.5mm plug wires, and a 60 shot of nitrous, along with other little things like springs, short shifter, strut bar, etc... All in all, I thought it was a pretty nice setup. The NOS really gave the non-turbo a kick and embarassed a few hondas. But I still had to stay away from every turbocharged/big horsepower car around.

So, a few months ago I finally broke down and went big, Hahn Racecraft Stage II turbo kit. At sea level, this kit will double your horsepower, ie. 140hp to 280hp at 9psi. Currently I'm running 10psi and it feels amazing considering how slow this car was in the beginning.

So all in all, a turbo kit is definitely the best bang for the buck, if you can afford it. But heed my warning, your car will DEFINITELY be down more than one afternoon!! And as Art mentioned, you should probably think about a new clutch at the same time. My stock one lasted 10 days after it was boosted.

freeing up rotating mass is a must. a stonger clutch with a lightened flywheel will help with acceleration. lighted pulleys will help with the bottom end torque (at least it felt that way in my car). along the same lines, some lighter rims couldn't hurt.

definetly look at getting as much air in and out of the car as possible first.

[OneSlowEclipse]

Thats what I had heard, thats why the bored throttle body is on the way. My underdrive pulley will be here by the end of the week too so that will go on this weekend. The flywheel/clutch are things that I do not know how to do, and i hate paying people to work on my car. Im thinking nos might be a short term solution until I either gain some knowledge on how to do some other things, or until I build up some funds to do the major things. Anyone want to help me install a NOS kit... or have any recommendations as to which kit to get??

[hoffman]

the clutch swap actually isn't that hard on the 420a. just make sure you have everything you need before you start. ball joint boots, tranny fluid, tools, people that have done it before.

i think the recommended nitrous kits would either be N/X or NOS. a simple wet system taped into the TB elbow can be done in a day. just make sure you have all the proper instrumentation befoe installing any power adders.

[DSMxTSi]

Definately get some gauges before you do too much more, like nitrous. All you really need is an EGT gauge, but you could do engine temp and/or oil pressure too if you want that 3 gauge pod in your car. Don't bother with an air/fuel gauge as those are fairly useless and the EGT temps will give you a better idea of how rich or lean you are anyway. The underdrive pulley will help quite a bit as well as the bored throttle body. Lighter wheels will help big time too! Our first mod on our 95 ESi was a short ram air setup and that was a nice seat-of-the-pants improvement, but as soon as we installed some fairly heavy 17" wheels that power was immediately taken away and then some. Don't bother with a Super AFC unless you get a turbo kit. An AFC may be needed with nitrous to richen things up a tad. My biggest complaint with our n/t is the huge lack of power on the bottom end, but it pulls really nice on the top end, go figure. So I plan on installing a lightweight Fidanza flywheel as soon as I get a new clutch and that will hopefully gain some bottom end. Nitrous is also in our plans for our 420A if a s/c kit doesn't come out this year. Also, remember to never remove your catalytic converter unless you get a turbo kit. I have a friend that can hook you up with a nitrous kit. Let me know if you need any help installing anything.

Thanks Cody, I would be interested to know about that nitrous kit, I am definetely in the market for one. If you could get me a price on that and I will locate an egt guage and possibly an afc, maybe I wont have 4 door saturns beating me anymore lol. Thanks again

i don't think you'll have a problem getting good, used S-AFCs now that DSMLink is on the market. check out NOS website to get a peak at the 'new' directport setup they are offering. it could be the answer to easy installs for kits that aren't going to be permanent.

[OneSlowEclipse]

I found a brand new s-afc for 250 bucks, from a fellow dsmer that bought it and never got it installed. I think that is a good price. I may not need all the features but it looks cool as hell!!

[303Racing]

It may or may not be in your plans or your budget. But if you really want power (at all times) then get a turbo. I played around w/ little mods such as air intake, wires, exhaust, etc. None of these mods gave me the grin I was looking for until I decided to get a turbo.

Unfortunately I have grown accustom to the current hp and need to find that grin again. Not only that but I want to make some of you 4g63 guys see nothing but tail lights. In a few weeks it should all be a reality.

[hoffman]

well i'll put it this way, from a rolling start, the Hahn stage II kit is the same as a stock gsx.

the 420a can run 9s, everyone knoes that now. but on street tires, i don't think you can crack the 11s. but 12s is damn fast for FWD.

oh, and $250 is a good price for a new s-afc. they usually go for $300. have fun with the install:p

errr... DO I HEAR A CHALLENGE???

[BoostedGS]

Actually, let's put it THIS way....

From a rolling start, the Hahn stage II kit is FASTER than a stock GSX. When Art and I raced, we were dead even and my clutch was slipping pretty bad.

Since then I have fixed my clutch. Last weekend I raced a 97 GST with a 3" exhaust. He got the jump off the line because I sitting on sand when I launched, so I was a car length or two down right off the start. By the time we crossed the 1/4 mile mark, we were almost nose to nose again.

So the super16g definitely pulls harder than a stock GSX, but you'll always have to chase them down because they get the jump on you at a light.

[303Racing]

I cant be for sure about the "X" but the stock gst guys run around a 15.4-15.3 I ran 15.3 on 5.5lbs of boost at bandi and with no other mods other than a greddy cat and hrc stage 1.

from a standing start, i think i will work you. if i manage to put 2 cars on you before you gain traction, i don't think you could catch up in a 1/4. just my .02, but we will never know until we run.:D

[SPEEDINRACER]

My GS has an automatic, do I still have to upgrade the clutch?

[303Racing]

Your car doesn't have a clutch.

[OneSlowEclipse]

Weeeeeeeeee!!!
