Im planning on bolting an evo3 on this summer, What do i need for my car to support this?


My car is bone stock except for a catback & megan downpipe.


Ive been told i will need a walbro fuel pump and maybe new injectors but id like some more opinions.


Thanks guys
 
You don't need anything if you're just going to run it at low-ish boost, but if you plan on maxing out the turbo, as the other poster said, a new fuel pump and bigger injectors, along with some way of controlling the bigger injectors is a bare minimum.
 
well ya thats what i meant... if he doesnt want to do all that then the max boost he could run is 12psi... of course he will see hp gains but nowhere near as good as if he did the supporting mods..
 
Not trying to be a dick but see the button towards the top right of the screen that says "search"? That button click that and ask the question there.

This has been covered to death. And personaly if i were a mod, it would be locked and deleted.

But since im not trying to be a dick and you obviously want to be spoon fed like a baby here you go.

You need ALL of this to get the most from the turbo, not to say you cant run it with less.

650cc injectors
Large FMIC
Walbro 255 pump
FPR
Crushed 1g bov or somthing similar
Cams
Clutch upgrade
Full 3" exhuast
Boost guage and afr guage
Tuning more than just an afc (dsmlink or afc + eprom and chip)
Nice intercooler piping
1g throttle body
Dyno time or lots of passes, basicly TUNE IT
~external wastegate, would come in handy but not 100% needed~

Im sure im forgetting somthing but that should do it.
That should do it
 
Id personally purchase a pump atleast since the turbo will creep because you have a different downpipe.
But if you're going to do it right id say get a 255 pump (same price basically as a 190), atleast 550 injectors (id gete 650s personally), and an afc ATLEAST. The evo 3 likes to creep to 20 psi for some reason and it would really suck if you put it on and one day crept to 20 and kaboom. I've seen it happen.

mine went to 26psi on pump gas and pop. Cometic HP headgasket poped. Thats when i purchased my tial external gate.
 
IMO your are not even close to being ready for an upgraded turbo.
1.) You do not even have a boost gauge (Should be your first mod)
2.) A Logger of some sort is a must if your a planning on doing a modification like this
3.) You need to get the supporting mods (Listed above) to even "feel" a difference or else when you slap on the Evo III it will actually make your car slower then it is currently
4.) From the sounds of it you need to do A LOT of research

(Crawl before you Walk)
 
Like the others said, boost creep will be a major issue with that MR downpipe. And like it has been said as well, you are not ready and definitely not NEEDING a turbo upgrade right now. But if you wanna be boneheaded then do what the others suggested but do yourself a favor and spend the extra $100 to get that new shiny turbo(that won't be challenged at all without supporting mods) ported to the full extent that the seller offers. That way you won't have to worry about boost leak, or you could finally get that new thing that's out called a boost gauge and monitor your boost that way but porting is worth every penny plus some.
 
:talon:
But, don't forget to factor in a AFPR with that 255 (which makes the price higher then the 190):thumb:

As long as he would get a 255lph hed be fine. I've been runnin a stock fpr with 650s and 255 for 6 months now getting 25mpg or so :) The only time it will really have a large effect on you is at idle (i didnt say only, but the main effect is then.)

Oof, i just realized you don t have a boost gauge. Here's some tips of things you absolutely need in your car regardless of wether or not you're upgrading:

Boost gauge (autometer...although i've heard they're not very accurate)
Datalogger (palm m100 with mmcd software or tmo or something of that nature)
AFC (if you're feeling frisky, because you can always lean it out a little bit)

Now if you ARE going to upgrade your turbo then everything mentioned above and:
Fuel control (if you wanna use the afc then great but dsmlink is far superior to that!)
Injectors (id really just go ahead and get 650s. Unless getting link, then get atleast 850s *depending on how big of a turbo you're going to eventually buy)
Fuel pump (you can pick up a used 255 for 60 bucks)

Anything else that you would/could get is totally optional in my opinion. You can tune everything from your logger/afc combo. And if you were to get link....yep, you smooth sailin :)

Hope i could help a little bit

BTW: If you do decide to get that turbo....agree with the other person and PORT THE HELL out of it or you'll regret it....unless you have the fuel and tuning software available..then it should be a good time. :thumb:

Just so we are all clear here, the porting services offered by most vendors are not intended or successful in preventing boost creep. They basically port the exhaust and/or compressor housings to open up air flow a little bit.

Porting to prevent boost creep on an EVOIII 16g requires that you port the wastegate flapper area as well as the wastegate entrance in the O2 housing. A good "how to" article can be found here...

You don't need a large fmic to make the most out of it. All you need is a street fmic.

Even though you think you might be running fine without one (which you aren't because even yourself admitted that your having problems at idle which is not running "fine") doesn't mean that he could run "fine" with out one too. Every car is different. Its a proven fact that if you want to run right with a 255 then a FPR is needed. Plus even with an EvoIII a 190 will be more then enough for his goals.

ok.... when buying an IC why pay 100 dollars less for somthing smaller? My core is 24x10x3 i think its on the large side and if you plan on maxing out a 16g its not going to hurt to go larger.

Thats what im saying, its not going to hurt when you are trying to get the utmost from a turbo. And in a month ill let you know what a stock shortblock evo16g with everyrthing i just listed can do. Shooting for around 400awhp, made 340awhp on the small 16g. I dont think its going to be a problem.
 
Can be done, i never maxed out my evo 3 but i did turn it up to 27 psi on pump gas....no knock i might add and flowed 39.7 lb/min of air. Stock 7 bolt.
A 190 pump if you intend to run boost that high, will not sufice. Get the 255 and an afpr (if you want to do it "right"). But like i said, its up to you :)

Incorrect, he should not run out of fuel with a 190lph. The 16g cant push enough air. Andy was running a 2.3l stroker on a 16g and still had enough fuel. He said he had a problem when he added his cams but he is running a stroker.

Why? Because there is NO NEED to hack the shit out of your bumper/completley toss it just to run a huge fmic with a small evo 3. I can see getting a big one if you're going to run a 50 trim, but not an evo 3. On ETS going from a street kit to the Pro race is an extra 200ish bucks. It's just not practical.

A 50 trim and an evo 3 are basically the same compressor wheel. You would need a larger intercooler to run the evo 3 than the 50 just because the compressor housing is smaller. Why do you think you can run more boost on a larger turbo on pump gas...the air's not as hot and the turbo doesnt have to work as hard.


And as far as the 190 running out of fuel with the evo 3, sorry my addiction for being correct set in and didnt intake the fact he doesnt have cams :p ....My bad...should be good on the 190 hehe :talon: :thumb:
