BEST first mods and free mods?

[wakesk8te]

Ight guys, whats the best first few mods I can put on my 98 Auto GST..

I plan on making in the 350-400whp range in the future, what mods would be the best gains that I can use later on down the road..


Any Free/Cheap mods that would put my car running top notch?

What mods will yield what amount of HP?


definatly planning on soon:
Shift Kit
tranny cooler
nice turbo header
DSM Link
???3000 stall TQ converter???



what is up with the END gear on the auto tranny's eveybody upgrades to? is it something I can do while installing the shift kit?

What would be a NICE quick spooling turbo for my setup?

For modifications, look at the Tech/diy on this site.

For a nice spooling, powerful turbo how about a 20g?

I wouldnt waste my money on a "turbo header" when a ported 2G manifolds can support 350-400horsepower. An EVO III 16G would give some quick spool and would still be capable of the horsepower you want. Actually, since your a 2G, a T28 might be a nice option aswell. Exhaust, I would invest in either some 2 1/2" or 3" 02 housing back exhaust. And if/when you do reach your horsepower goals, you'll definetly be adding some drag slicks to your wish list.

Yeah, Definitely check out the link above, there's great free-mods that can be done first.
And you'll want to do a good tune-up if you just got the car and dont know its condition.
The end-clutch is replaced because it tends to go out on these cars. And yes its very easy to do and can be done at the same time as the shift kit. I would suggest a modified valve body w/ shift kit from IPT.
Hold off on the Torque convertor, i believe stock stall speed is 3000 or 3200 anyways..
I'll give you a breif rundown of my cars setup with around 400hp, just so you get an idea.
3" Turboback exhuast, Hard Intake pipe w/ hacked can and mas, Tubular Exhaust Manifold, Evo III 16G, 660CC Fuel Injectors, 190L Walboro Fuel Pump rewired, Small FMIC w/ short running pipe, Sheat Metal Intake Manifold, DSMLink, a larger tranny cooler, modified valve body w/shift kit, fluidyne radiator, oil cooler, of course gauges and boost controller.. I'm sure thers more but you get the idea.
Suspension you'll probably want some lowering springs and maybe some adjustable shocks, strut bars, maybe larger swaybars.

Your saying 400 to the crank right?> Because theres no way you have 400 to the wheels with a 16g and a 190... But your right about the tune up thing...

An Evo III will be hard pressed to make 350-400 whp, and it would be even harder with a Big T28. Looking at your mods list in the post above, I would recommend larger injectors since you're going with DSMLink. With the amount of power you're looking to get I would recommend going with a rewired 255lph hp walbro or even a rewired supra fuel pump with an AFPR. A rewired 190 is limited to around ~4 lph of fuel at 20 psi of boost, and that number decreases dramatically with more boost. At that point I would recommend cams before a SMIM, and if you were going to get only one then I would definitely go with cams.

You listed a tubular manifold, which you have a wide variety of flanges to choose from--Mitsubishi, T3 or T4. If you are actually going to plan this out this far ahead of time, I would look into a T3 flanged manifold with an external wastegate setup if you are going to go all out. This way you can get a custom made downpipe first (instead of having to replace your exhaust setup like most people). This gives you an enormous selection of turbos to choose from, and you can go from there.
At the very least, look into a mid-sized turbo like a "50 trim" hybrid, either T3 or Mitsu flanged depending on what you decide to do manifold-wise.

For your first mods, I would say a cheap UICP with a 1g BOV. Then do any cheap stuff you can get out of the way like a MBC/boost gauge, intake and/or filter, etc.

Second that
1. Boost gauge
2. Intake - do the free mod on BOV dump tube then either hack the air filter can or go to a 4 inch K&N.
3. UICP - I went with a Dave Brode with 1g BOV, ebay $70 - this added more HP than any other single thing that I have done. Then start thinking about what is next

EVO III can meet your goal....with race gas that is. Well, let's see...most the free mods are overrated so you can waste time if you want on them.

1) you are FWD (means you should go bigger;faster spool=no traction)
2) you are A/T (means you should go bigger)

You can rule out the EVO III now. Although the Green (or 50-trim) is not a big jump, in this case, I would recommend it because the differences are in your benefit. Capable of making ~450WHP on race gas and capable of reaching your goal on pump. Also lasts long too. You don't "need" slicks as you won't be launching too high. Just make sure you have enough fuel (injectors, pump, controller, etc...) to supply your boost levels. If you're new to tuning, you'll need a logger to monitor knock but if you've got the experience...you'll already know the ropes. Good luck.

Can we all cut the crap with these Evo III recommendations for a 400hp car??

2" inlet + 400hp = not in your lifetime

Let's get real people, race gas doesn't make a difference. It just IS NOT going to push that much air. STOP RECOMMENDING IT!!


Do yourself a favor and get a 20G or 50 trim like a few other recommended.

 

[RedTurboEclipse]

Your goal is 350-400whp, and your asking about free mods? I wouldnt even bother with the free mods unless you are planning to leave your car mostly stock for a while. If not, the mods you will be doing to reach your goal will negate the need for free mods. An MBC, a new intake pipe, an fmic. I believe those 3 involve some of the major free mods involving those areas.

A big16g variation can reach your goals, but thats really pushing it. 350whp at most is what I can see. DSMLink will truely help you. I'm sure you will be pushing that 16g. And at that rated HP, I am assuming you will be getting the best variation, which is the EVO III. And get some cams with that pushing it at near its max efficiency, and I can clearly see 350fwhp.

Personally, I would go with a 50 trim type of setup if you are looking to see 400whp in the future.

WTF I don't think anyone recommended race gas. Someone, me, did say the EVO III could reach his goal but with race gas...and then I ruled out the EVO III. Oh yea, race gas makes a hell of a difference. Don't tell me 20psi is not much of a difference to 27psi on an EVO III. Of course race gas doesn't push more...duh...it allows for the turbo to push a hell of a lot more air safely. I still have not recommended it...especially for rookies, oh wait I'm a rookie myself. Your post is almost identical to mine.

For you, being an auto, consentrate for sure on the Tranny Mods. Get a big tranny cooler, IPT shift kit, and possibly the end clutch kit first.

Next Concentrate on flow, no need for a manifold, a ported 2g will get you there. Exaust (Megen Racing is good) and an FMIC (The xspower short route kit is awesome). Why pay $10 for UICP when you can get an entire FMIC for $300. Get a bolt on PTE SCM3431E (http://dsm.dejonpowerhouse.com/) for your turbo. Being FWD, spooling a little later will only help you!! That turbo will be perfect for your goals. Of course DSMLink and Fuel (255hp, afpr, 850cc FIC injectors).

and your there....
so, summary, in this order
-tranny mods
-dsmlink
-fuel
-turbo and fmic
-if you are still not there, cams and Meth

You're right, no one else said race gas but someone else said Evo III. I flip when I see "Evo III" and any number over 300 in the same sentence. I didn't direct that post at you, but at the overall Evo III love that too many people on this board have. They act like its THE all powerful turbo sent from heaven.

Yes race gas helps, but no one fills their tank with 116 leaded when its getting low.

Ahh...yes. I agree with you about the EVO III. Think about it though...the ones that are praising this turbo are mainly the ones who have never owned anything bigger. Honestly, it is very capable of over 300WHP....with race gas that is. Pump is a different story.

I will agree with you on tranny mods, but a SCM3431E? What's your basis on recommending this over a SCM5031E? If he were going to go larger then why not go straight to the SCM6031 (60-1 variant with the Stage 3 turbine wheel)? The tradeoff in lag for power would be more justified with a 60-1 sized turbo.

All this discussion is in the end supposed to help him make 350-400 whp (assuming on pump). He requested a "NICE quick spooling turbo for (his) setup?" and one of the most obvious choices would be the ball bearing version of the SCM5031--enough flow to meet his power goals, and spool between shifts as well as initial spool would fit his request.

As for the Evo 3 not making 350 to 400 whp, yes it has been done but those vehicles are definitely in the 3σ (3 standard deviations) class (top .3%) to be able to make that sort of power.
