Just Bought an EVO III Turbo

[nightstocker99]

Well I just bought and EVO III turbo and I have little done to the car. I was wondering what I would need in order to car the car run right and not blow up or anything. I am going to turn down the boost with a boost controller until I get the items needed, so any other ideas would help.

Be very careful of boost creep, which will occur almost invariably with any level of modification. At the bare minimum you will need more fuel (injectors and fuel pump), a method of controlling that fuel (wide range of options). Nice things to have in addition to these include an upgraded intercooler and a clutch.

The bare minimum shopping list would be something along the lines of pocketlogger, SAFC-II (around 200 on classifieds), 550cc injectors (around 200 on classifieds), Walbro 190 fuel pump (95 dollars new from extremepsi.com). Beyond that you would just have to tune everything out.

If you have any more specific questions about what I've said let me know and I'll expound on what I've written.

The list above sounds about right. I would recommend that if you're ever going to cam your motor that you step up to a 255 pump with an AFPR and also go with 650 injectors to enjoy the potential of the EVO III. Creep will certainly be an issue at lower boost levels, but as you add correct fuel mods, you can raise the boost and come close to reaching the maximum creep point. For now, try to keep it at 12-13 psi until everything is installed and tuned.

Regarding the AFC, I don't care for the way it skews the timing/airflow maps and you'll be fighting knock as your remove more fuel/airflow to compensate for the 650's. I'd recommend an EPROM ECU with a Keydiver Stage III chip. I can help you with custom fuel and timing maps that will give you a safe and powerful tune and let you read knock, without resorting to the tail chasing antics of tuning an AFC.

Good luck and drop me a line if you need a hand,

With 550cc injectors your timing (again for most people, your results may vary) is generally not an enormous problem. However if you do step up to larger injectors such as 660cc or higher you will begin to have problems as Andy stated above. There are many choices for you should you decide to begin upgrading your fuel system. Once you get to this point you can either start searching your questions, post it, or PM either of us.

So to start off i will need a set of 550cc injectors, a SAFC-II, and a walbro 190 pump.

Do you think I even need to turn down the boost i am running 13 psi now or should i turn it down until i get the 3 items listed above?

EPROM ECU with a Keydiver Stage III chip. I have never hear of it what does it do.

With the turbo and the 3 items above (tuned right) what would the percentage gain of hp be?

This is an overview of what the keydriver chips do.

This is the best way to go, I'd thank this guy (Andy) for the best advise on tuning fuel system and went with Eprom. Now my SAFC and Data logger became Xmas ortiments for my car, (waste of money). My Erpom+ stage 3 chip + ship+no tuning needed = $380+ and SAFC2 + logger + frustration tuning cost= $279+170+ = $449

where did you get the EvoIII from?
If you dont mind me asking that is...

All cars are different when it comes to mods, You'll have to go to the Dyno to kno for sure. But you should notice quite a difference once tuned. I also agree that you should get a Keydiver chip they're well worth it, you get stutterbox and NLTS depending on which one you get.

If you want to run the EVO III to it's potential, 650's are a better choice. Buy injectors once and be done. With the Keydiver chip you could run 850's or 950's and have plenty of room for future turbo growth since the compensation for the injectors is handled in the chip.

For now, your boost level is fine at 13psi. Keep in mind that if you want to run without an AFC, you'll need to get together with Jeff from DSM Chips and let him know that you want custom air/fuel ratios and timing tables. He can put those in for you and they work like a champ as Jerry mentioned above.

Le us know if you have more questions,

Andy

So to start off i will need a set of 660cc injectors (i don't think they make 650cc), a (yes/no) SAFC-II, EPROM ECU with a Keydiver Stage III chip, and a walbro 250 pump.

If you go with that setup you'll need a pocketlogger. Your other choice would be to ditch the AFC and keydriver chip to go with DSMLink, which will cost a little more.

Regardless of what you choose to do, you will need an AFPR with that Walbro 255. If you do stick with the 255 I suggest getting the high pressure variant and rewiring it so you'll never have to upgrade that portion of your fuel system again. Also, with either setup, you should consider getting a wideband to tune with (although this isn't necessary).

I am not understanding what you are telling me!
All I want is the basic upgrades that will let my engine run right. My goal is just 300 whp thats it. It just want the items that will get me there safely and correct. I don't really want a dsmlink or a pocket logger i just want the things that will have the car run right.

You will need a Pocket Logger in order to know you are running your car saftely. You don't need DSMLink, but it will be really useful if you had DSMLink.

Also, people have already posted what things you need at a bare min to run that EvoIII. Some people are just suggesting a little more in case you want more. Once you feel the power of that new turbo, you'll know you want more ... then you'll come back here thanking someone for recommending you 660cc injectors instead of 550's.

 

[nightstocker99]

660cc injectors, and a walbro 255 pump, and a fuel pressure regulator of some kind maybe a fuel rail?

now which one of this do i need a SAFC-II, or EPROM ECU with a Keydiver Stage III chip, or a dsm link

With your shopping list : 660s, 255, and fpr

You can get away with just buying : SAFC-II (though some will argue that anything past 550cc is less than ideal for SAFC-II)

A better option (according to others) : also get a keydiver chip (this would allow to compensate for the less than ideal injector size with SAFC-II)

Best option (unanimously) : DSMlink (this would remove the need for SAFC-II and keydiver, as well as compensate for injectors, plus much much more than you may ever need or understand)

Since you are looking for the cheapest possible outlet, based on my experience and 'knowledge,' you should be able to get close to or reach your 300whp goal with just SAFC. Personally I am trying for 300hp as opposed to whp and my end setup will be 550s, 190, and SAFC-II. I am considering 660s, but am unsure becuase of the aforementioned less than ideal situation.

edit: added some comments

 

[2gGSX]

If you want the absolute bare minimum mods necessary to support an Evo III, then it's:
-pocketlogger/SAFC-II
-550cc injectors
-190 lph fuel pump rewired
This is bare minimum because you'll get the car running, but above about 35 lbs/min of airflow your injectors will start reaching over 90% IDC. At 95% IDC you'll be able to support 37-38 lbs/min of airflow. Basically you'll already be pushing the limits of your setup right after you get it, but this is definitely the BARE minimum.

 

[MyBeatGSX]

Come on guys, 550's will do 300whp all day long. No problems at all. Get the 550's, SAFC, and a 190. That's bare minimum, it will work just fine, and make decent power. End of story.

i mean its only ben proven many times before.
