Hey guys I finally decided to go turbo! I have plans for the setup i'm about to list and have it installed by the middle or end of next year. Well here it is, and please by all means rip it apart if it does not sound right.

Before I list it I just want to say that this car will most likely not be raced. I want a dependable daily driver that is unique and really fun to drive. I love working hard towards a goal, and my goal for this is to have the kit running in ANY weather conditions and for ANY period of time, even long long 16 hour back to DC drives.

-A-2 Designs Kit with a T-25 turbo (I want boost early so I don't have to rev really high to enjoy driving the car)
-Greddy Emanage (could someone tell me if i need ultimate?)
-Autometer boost, egt, oil pressure
-AEM UEGO wideband, or zietronix, etc
-High flow cat, upgrade my exhaust to 2.5 press bent
-Possibly A-2 return fuel conversion
-Greddy turbo timer
-Manual Boost controller
-And I'm sure a new clutch shortly after

Now, this is where I need help. What things on that list are unnecesary? I do not want to waste money, but I want my setup to be safe and reliable. I WILL NOT BE TUNING THE CAR MYSELF. I plan on getting on the waiting list for AMS in Chicago eventually once i start getting this put together.

One more thing, I will not be trying to push crazy HP into this engine. That is down the road when I get out of school. What boost level should I run for decent gains but ultimate reliability?

Thanks in advance for all the helpful input you guys give

 

You don't really need the Emanage. atleast not right away.

how much boost do you plan on running?

 

I'm not sure. I know boost levels on a T-25 will be different than boost levels on a 16g or T-28. I just have no interest in blowing the motor, although I understand aftermarket turbos always carry that risk

 

T25 can boost about 10-13 psi, and anything beyond it makes it about ineffective blowing hot air.


Otherwise, bigger injectors and tune them downwards. I don't care about other products on here how they overwork the injectors to do simulate it like bigger injectors. IMO, it's like overclocking a CPU, how long will the CPU last until it's toasted from the heat and the everyday wear and tear. Or better yet, overclocking a pacemaker in a person.

 

What I think you are trying to tell me is to not run stock injectors or overuse new injectors. The kit I am buying comes with new injectors so I think that should make me ok. can anyone clarify?

also I've got another question. i've put a wideband and the emanage on the list. can i have one without the other and still have someone tune effectively for me? I want the tuning to be as safe as possible. what i'm trying to do is narrow this list down so I don't buy parts that i don't need

 

Yes you can have a wide band without the Emanage. The emanage takes the place of your stock ECU and allows you to tune your car and turbo, allowing you to tune for more than just A/F.

The wideband will allow you to read the air fuel ratio and thus allow you to tune. You need a wide band to tune. Without it you are guessing and that can lead to a big boom.

What you have to ask yourself is what you want to be puttind down as far as HP. Anything above 230 whp, and I'd say there is other stuff you should be looking into. Such as: a Limited slip, better tires, suspension, aftermarket clutch, forged internals etc. You'll also want to, at that point look into getting some kind of stand alone that can be tuned for that kind of power.

I think that at 7-10 psi I should be good with a SAFC or a reflash, of course get a wideband and make sure you know what the hell you are doing. Otherwise, like I said, boom!

Thanks for clearing that up! Ok so from that I can gather:
-Wideband is necessary no matter what, it accurately measures AF ratio
-SAFC controls my air/fuel ratio and can be used to tune to a certain extent
-emanage allows greater tunability

So, do i need to decide between an SAFC or the emanage?

My goals for hp are not very high. Definitely not 230whp yet. I was thinking around 200 or more at the crank. This will all change once I get out of school, but for now i want to turbo at a slow pace and work my way up

As you guys can tell i still have some learning to do, thats why i'm planning so far in advance

 

Depends on how far you want to dive into tuning. An SAFC will provide you with the ability to change you air/fuel ratios ONLY, your basically only changing one parameter. With a wideband it should be pretty painless to achieve an alright tune.

An emanage will basically let you manipulate your A/F aswell as have full control over igntion timing. Gets a little more tricky. Strongly suggest a wideband/egt combo to tune.

There are a ton of other options out there. Just do your research before you buy.

 

absolutely i'm going to be researching for a month more before I begin buying these things. So theoretically if I bring the car in with the turbo kit to get it installed and tuned, what are the best tools to have so the tuner can give me the best tune?

from what i've gathered the emanage, wideband, and exhaust gas temperature gauge would be the necessary items to get the best tune. is this right?

thanks for the help so far!

 

Why dont you just take a hit on the 04' and buy an evo? IMO a better solution than this madness...o yea AWD too

 

definitely a point to consider. although i think this route is more beneficial because it will allow me to eventually know how performance parts work in and out. i won't be able to purchase an evo for years due to law school and insurance rates. basically i'm setting myself up to really enjoy the next car i own, and of course this one

 

Whether new or old injectors of the same stock size, I don't think it's prudent.

Here's the math in flywheel HP. If people think the math is wayyyyy off base from reality, I DARE (triple-dog dare) anyone to write to RC Engineering that they don't know anything, and all their past experiences are crock.

Math don't lie. 1+1 will always be 2. Scientists predicted blackholes in the universe (late 70's) using math way before radio telescope picked such imperical proof in the mid-80's.

 

haha, for a t-25 i would run a steady 7 psi, that should get you around 200 and most people like to run 370cc injectors

 

7 psi on a t25 netting 200whp? i don't think so.

 

maybe consider the t-25bb. ball bearings for faster spool and longer life.
