Hey i'm in the looking stage for a new car and the three cars are a lancer evo, srt-4, or VR4. So i'm trying to research the evo because i really want awd.
So i'm wondering if i get a boost controller i can set the boost up to on the stock turbo and also will i need a apexi fuel/air managment system. So please help me make the right choice. I know the stock car is set at 19 psi wondering what i can get it up to.

Thanks Tyler

 

man can u ask ur question again but in English, i'd like to help but not following too well....

 

First what VR4 are you talking about the 3000 gt is not in production, and you could only import the galant VR4.

Srt-4 doesn't even come close to the evo, i had someone trade in his srt-4 over the weekend for an evo. He bought the srt-4 2 months ago, and it only had 2400 miles on it.

the evo has a cast iron engine is remarkable, you can use a boost controler and gain about 2-3 more psi. or upgrade the turbo to 24 psi with out modifying the engine.

 

stock turbo can go above 2bar with the correct most done to it and the engine. you could be looking at around 400whp at 1.6/7 bar redline with anything upto 2.3bar in the midrange. for this you will need a ball bearing conversion as the stock bearings will not take that sort of load.

hope this helps, Chris.

Ps. dont waist money on a boost controler, just get a standaloan.

 

First Off all, i would buy a 3000GT VR4 with lows miles.

1.Here is my question what psi can i run the stock turbo at like 21.

2.Another Question what horsepower will i be running with a HKS Cat-Back Exhaust and the turbo topped out.

3.Because i want to bet the srt-4 from a roll because i don't think i can keep with it on a roll race ( that is a srt-4 with stage 2.)

4 Also will i need a apexi SAFC 2. Planning on get a Greddy Type-S BOV Too.

 

Are you high?
MBC = 25-50$
Stand alone = 1000+ $

Back on topic.

With the right mods you can do well with the stock turbo. I'm tuning for 20-21 psi on my evo. Hopefully I will be making 320+ whp. I know right now I am doing a little over 300 WHP untuned.

 

Because mate, if you plan on running serious horse power then you will need a standalone anyway, so why spend money (even if its not a lot) on stuff that will be useless in a year or so? You will also see more power running a standalone than what you will by using the stock ECU and a MBC/EBC and AFC. They will also let you run stuff like launch control and anti-lag!
With a good set of cams (like Pipers, Tomei or JUN), a larger intercooler, an uprated fuel system, exhaust, intake, uprated clutch and a standalone, all set up right then you will be looking at the hot side of 400wbhp. The only problem that you will have will be with the turbo. To solve this simple get the turbo fitted with ball bearings. This will let you run around 400wbhp with no lag! This is really popular with people in the UK and several companies are responding with this type of conversion. I have yet to see ANY in the US though. As said before, 2bar is possible, but you will only need around 1.6 to see 400whp and similar amounts of torque!

Chris.

Ps. not high mate, and these figures are proven!!!!!!!!!!!

 

I have to agree with Chris on a few points.. however the standalone is a bit expensive and can be an issue with inspections here in the states. Try to plan what you want to do, otherwise you'll spend more money on replacing stuff that you want to upgrade.. (I went from an MBC/S-AFC to an S-AVCR/S-AFC to a UTEC)

I also wholeheartedly agree with the fact that our turbo design is capable of alot more than anyone has given it credit for. an Upgraded O2 housing, upgraded exhaust manifold, removing inherant restrictions in the intake and exhaust tract, and upgrading the turbo cartridge to a (preferrably BB) upgraded turbine/impeller and a small bit of porting could net you quite a bit of power. If you get real creative and do some headwork, probably quite a bit more.

The twin scroll design works well, but nobody in the states is actively pursuing getting the most out of a stock turbo housing. Its twin scroll, therefore you can use ballbearings to assist in spoolup after modifying the the cartridge to move more air. In the end you get alot of HP and its very drivable. I do know Buschur Racing is working on a stock turbo replacement using the stock turbo housing, turbochargers.com also is working on something. But I do not know whether their BB or not. The reason is everyone thinks bigger is better which is not always the case.

 

What octane are you going to use? With 93 or 94 I would not run over 20 PSI on the stock turbo daily.

You don't need a fuel controller, but it does help. The stock car runs really rich at higher RPMs.

 

thought the stock evo8 turbos have bearings... :P

 

They do but they are journal bearings not ball bearings (i think...

 

Tyler -

My suggestion would be check out some of the tuner websites. This should give you the best idea of what the EVO is capable of. I believe that Buschur has taken the stock turbo the furthest with a 11.65 @ 118 mph. That should be more than enough to whip an SRT4.

The drawback of the EVO is that it's $10k more than a SRT4. I doubt any will argue that the EVO is superior but for cheap straightline speed you can't beat the SRT. Stock vs stock the SRT is very close in acceleration. The big downfall to the SRT is it's FWD.

The 3000 gt VR4 is a tank. It weighs somewhere in the neighborhood of 4000 lbs. It will not be nimble as the other two and probably the worst track car of the three. I've also heard stories of them chewing through trannies when modified.

 

Running 93 Octane.

 

Here are my plans, going to be a daily driver and on weekends, and some nights street racing or track racing. My goal is to get around 270whp or more.

So i;m wondering if i can run the stock turbo at 21 psi, get a HKS Cat-Back, and a Apexi Air/fuel controller. So i'm asking if i with those mods can get about 270 running on 93 octane. Can afford 1000 on a standalone.
Thanks For all the help

 

Tylerw, and everyone else for that matter. you will be able to get around 350bhp from an intake, exhaust and a standaloan anyway. dont forget that that is pretty much all that ralliart do for their FQ330 package! i know that they seam a large about of money, but it is also the safest way to get the power!

Chris.

Ps. thanks malibuJack, nice post mate, very informative! i agree that no one over there seams to be pushing the stock unit as hard as they should. you guys really do need some RS Ti turbos with bb cores!
