Evo 3 16g

[maxtsitalon]

I recently purchased an evo 3 16g turbo, ported 2g manifold and ported 2g o2 housing for my 1g. I searched and found no answers for 1g's. But i was wondering if i just put these on and run at 10psi will my car run fine? and will i feel any gains in power? I cant afford to buy injectors, fuel pump and safc yet so im just wondering if i should wait on putting the turbo in until i get the money to buy the rest. Thanks for any help.

Yes you can run it at 10 PSI and I'm guessing you gonna feel some extra power GoodLuck with everything. Also untill you get the supporting mods don't go above 15 psi.

Yea. I was going to say you can run more like 15 psi. But just don't do any more. At least without a logger.

 

[maxtsitalon]

Is there anything i should look out for when installing the turbo? any helpful tips?

Actually you are not going to feel much gains until you get the supporting mods. At least get a fuel pump and do the rewire mod for it. The fuel pump rewire mod costs about $15. Get a 195 LPH if you don't want to need a AFPR. If you get a 255 LPH you will need to also buy an AFPR. You can buy the fuel pump from E-Bay or one of the verified vendors.

Also do a boost leak test before you start running the new turbo. Do your testing at the throttle, the intercooler, and the turbo for leaks. With the bigger boost pressure, you are going to have problem with leaks. You may also end up with boost creep, since the Evo III 16-G is well known for it. Do a search on resolving Boost Creep by porting. I have had my Evo III 16-g for 3 months now and am still resolving boost leaks.

The EVOIII is more efficent than the 14B at any desirable PSI, therefore you will see some gains. The EvoIII swap on a 1G is pretty much in and out. Unless your now changing J-pipe. Then you will have to mess wiht the IC piping an bit, but im sure its nothing you cant handle.

I second that. I had an Evo III 16g on another talon of mine, ported exhaust manifold and 02 as well, and I had a lot of boost creep (it was during the winter though, weather will play a large role). It wouldn’t hurt to look into porting. A lot of DSM sites sell the larger flapper if you were to expand the wastegate.

That is NOT true. Up to 15 psi, the 14B is in fact slightly more efficient. See: 14b compressor map and 16g compressor map. So there will not be any noticeable difference because of compressor efficiency.

However, the turbine housing of the EVO3 is a 7 cm^2 housing which flows more exhaust gasses than the 14b 6 cm^2 housing. This higher flow provides a higher overall volumetric efficiency and generally yields more power. This will also increase turbo lag.

It is more effecient, but if you are running a completely stock set-up, the car isn't going to run very good until at least the fuel system has been upgraded. There are plenty of forums and turbo web-sites that talk about how you won't see any major improvement until you at least upgrade your fuel pump. If you get DSM Link, or a SAFC II and bigger injectors, with the bigger fuel pump you will then see major gains. If you read a lot of the Evo III 16-G forums people talk about how there cars ran worse when they put the new turbo on until they got some supporting mods. These turbos are made for some serious supporting mods being installed.

I would at least throw a feul pump on it, and then get things later down the line.

It will run just fine. It will run like stock with a little more umf up top because of the larger turbine housing associated with the evo3. It is not more efficient until after 15 psi. He will feel a little more pull up top with the evo3 installed and running 15 psi. But nothing to right home about. It is not more efficient at 15 psi. Compressor efficiency is important, but it won't give you much horspower gains by itself. See stealth316.com: 4th paragraph down from the sub-heading.

In short: it will feel very slightly stronger up top and will run like stock everywhere else. it will not run bad. it will run like stock everywhere else in the rev range but up top (where stock cams crap out). i've ran my 18g (bigger than the evo3) at 15 psi and felt no difference at all versus the old 14B at 15 psi.

Show links of where the EVO3 ran worse until the boost was raised! The evo3 is a great turbo for stock cams because it is small and has a hard hitting midrange.

To the original poster. . . you are fine and will feel no real gains or losses by running the EVO3 up to 15 psi. After that, you will need supporting fuel mods. But nothing more than 550s, a piggyback, and a smallish fmic. Unless you decide to upgrade to some pretty wild cams and/or stroke your setup.

I agree with this 100%. You have a 14 year old pump. Exercise self control and don't run more than 15 psi or so and you will be fine until you get those things you need to get the most out of this turbo.

 

[EclipseTrbo420A]

I ran my Big16G at 14PSI on stock fuel for alittle bit all was well throw it on, get the supporting mods and enjoy it even more. A true statment about the 16G is they really wake up upwards of 18 psi. Also thanks for the correct info on the efficency of the turbo.

Please reread my post. I said that there are plenty of posts about not seeing any major gains until after the mods are done. I also said it is known to run worse until the fuel pump has at least been upgraded. Please don't be putting words in my mouth and making what I said wrong.

Excuse me! You said that it there are instances where it has run worse without a fuel pump. When do you need a fuel pump until you run over 15 psi? So you say that an EVO3 runs worse with a stock pump? worse than what? It runs just fine with a stock pump if your boosting no more than 15 psi or so. That is all I was saying.. . . .

No. no. no. Provide links, threads, . . . please, something, ANYTHING. Here, I have examples supporting my statement:

1. http://dsmtuners.com/forums/showpost.php?p=1622827&postcount=5

2. I ran my 18g (bigger than an EVO3) with stock everything and stock boost for about a week as I was about to sell all my upgrade parts. It ran great just as good as a stock 14b. Pulled a little more up top, but had very slighly more lag down low.

3. http://dsmtuners.com/forums/showpost.php?p=1525896&postcount=6

They are made for about 250 crank horsepower. They were stock issue on the evo3. They will go farther, of course. But they will not run worse than a 14b at 15 psi. If that was the case then the EVO III guys should drop the evo3 16g and run the 14B if they want more power without upping the boost . What psi does the EVO3 run at stock? Do not tell people that this turbo runs worse than a 14b at stock to 15 psi levels. They both run about the same at that level. MHI was kind enough to build a turbo that will run fine at stock boost to 20+ psi.

No problem. You know for the longest time, I thought that a turbo that was efficient at higher boost levels was even more efficient at low boost levels. And that any big turbo is an upgrade even at stock boost. The best turbo for stock boost and stock trim is the turbo that was installed by the manufacturer. They've poured years of development into this and balanced the budget with their warrenty. No manufacturer wants to release a car with a turbo that is less efficient than another at their chosen stock boost level. The 14b compressor map proves this.

Yup the SMALL 16g BIG 16G and EVO3 16G really start to perform well after 15 psi up to about 22 psi. I loved the mid range on my Small 16g. It was right there. My 18g hit suprizingly early but really made its presence felt after 4000 rpms to about 7000 rpms. My 60-1 is bitching at me for not turning the boost and/or the rev limit up.

Look, I don't want to get into some huge arguement with you. I never said anything about what specfic boost level the turbo was running at, so you are putting words in my mouth on that one, I never said it would run worse at 15 pounds than a 14b or T-25. I just said it had been known to run worse. The running bad doesn't occur in all the cars. I am just saying I have had read posts on this site about how peoples 16g's ran worse than their stock turbos until they installed the fuel supporting mods. Maybe they had the boost put up to high, I don't know, they didn't say. Nor do I want to go searching for the posts because there are like six Evo III 16-g posts a day, and I don't have hours to go searching through them all. Good for you for being able to back up what you are saying, next time I'll have to keep better track of where I read things. Mine was a suggestion from what I had read and nothing more, I was pointing out what others had said. To me the car isn't running good until you are living up to the basic potential of the turbo. I am not trying to arguee with you. You are probably right. The biggest point I was trying to make was that they wouldn't see any major gains until they do some modding because like you already said, this turbo was made to be run at higher boost levels. I have an Evo III 16-g on my 2g eclipse and I personally didn't see anything I consider significant in the improvement area until I installed my 255 LPH fuel pump and did the fuel pump rewire and I know the car could do a lot more with the bigger fuel injectors and the SAFC- II or DSM Link.

Well ok. That makes much more sense. The evo3 16g will cause one to hit fuel cut very soon after 15psi and will also overrun a 1g maf by the time you get it to it's meritted performance level for sure no matter what piggly back you have except MAFt! Then your only course is to go speed density (MAFTPRO, DSMLink) or a differenct maf (MAFt, ECU+, DSMLink, EMS, MegaSquirt). SAFC won't even suffice then . You are absolutely right that if one even remotely tries to get this turbo to run where it runs best then it will certainly cause your setup to run worse in stock trim.

I would just through it in. Im running a ported evo 16g, ported SBR manifold, ported evo o2 housing, and a full 3 inch exhaust. No supporting mods and I felt a pretty large increase in power. Running only 10psi, because I did create some problems when I turned it up. I raced my friend in his 06 mustang with exhaust and some bolt ons and stayed right in front of him, he was so mad be, he kept saying but I have 300+ hp. My car also is pretty stripped I weighed in at 2800 without driver, anyways I was pleased with the increase.

Hate to break it to you but all your porting, new manifold, bigger exhaust, and bigger o2 housing is considered adding supporting mods. You increased the flow greatly over the stock system, so yes you will see an increase in power. The original poster was talking about putting it on a completely stock system. That's cool though that you kicked your friends mustang butt. Just hope you did it on the track since they really frown on talking about street racing in here.

the turbo swap is quite simple, dont hurry, and dont get frustrated with the oil feed and coolant feed, it is also wayyyy easier if u take the radiator out its like 4 bolts. i had my turbo in and out in a matter of a couple hours.also do the ss feed line if u have money to spare.GOOD INVESTMENT.
