I Spoke With The Tsi Rep And Did Not Seem To Know Much About Upgrading This Kit, Comes With Everything Needed To 8 Psi. I Want To Go To 15 Psi. I Have Rsx Type Injectors Coming And Have Pistons And Rods And Block Guard. Im Looking For Rec. For Any Other Mods To Reach My Goal Of 15psi. Also Have A Gude Racing Head Kit Coming. Im Using The Black Box From The Kit For Maping. Looking For Some Insite Of Problems To Look For Before Install .thank You For Any One With Experience In The 05 Civic Ex With The Tsi Set Up.
Note : I Did Get The T25 Ball Bearing Up Grade.

You can't run 15 psi w/o a better fuel system. YOU must convert to a return style and probably need bigger injectors. There's no way the stock fuel pump can flow enough to accomodate 15psi. Also what fuel management system are you using the tsi kit? That WILL DEF not be safe for 15 psi. Talk to some of these turbo gurus I'm only mentioning things you should be aware of.

 
Rep Power: 380

yeah you need a new fuel system so a return line and bigger pump, and like 500cc injectors atleast. type-s's won't go that high.

 
Rep Power: 239

Im Using The Tsi Kit For Know. Should I Use E-management Or Aem .
Im Not Sure What You Mean About The Return Line? I Will Upgrade The Injectors To 500 Cc Not A Problem ,any Idea What A Good Company Is? Ill Upgrade The Full Pump In The Tank. What Is A Save Psi Level With The Sais Upgrades Above? Thanks For Great Ideas .

Keep in mind guys this is a t25 or t28 so 15 psi isnt going to be as crazy as it would with a bigger turbo. None the less upgrade like they said and have fun.

 
Rep Power: 424

at 15 psi a T25 is nearing the level of "hot air blower" that could be pushing efficiency on it.
The only useful advice I can think of right now is STOP
First of all, if you dont know anything about upgrading it, I wouldnt bother trying to run 15, I dont know if I'd even run 8 without at least an e-manage.
Figure out what the hell you're doing, because no one wants to hear about it when the motor blows and you don't know why.
Throw the gude head out, they've been proven trash and more trouble than benefit.
You need an EMS, probably at least 550cc injectors, a return system, etc....
There's a big gap between bolt on kit and lots of boost.
Then hope you can find someone who really knows how to tune, 15psi is pushing it on D series sleeves.

I Agree With You , I Do Not Want To Ruin My Motor And I Do Not Want To Be One Of The People To Come Back And Said I Blew It Up
Time To Start Over. Thats Why Im Here Hopefully To Gain Knowledge From The People Who Have Learned From There Mistakes .
Because I Wounder Even The People At Tsi Know What There Talking About. So Sounds Like 8 Psi Min. Till I Get A Emanage Ecu . And
I Will Stick With Factory Internals And Should I Still Upgrade
Injectors. The System Comes With Two Injectors,with The Black
Box For Maping. I Think I Will Get A Fuel Pump And A Regulator Any Way Because Ill Need It For Tuning Down The Road. .well My Ears Are Open For More Suggestions. Thank You Again.

well good luck on this..

i sure would have gone with tsi just from what has happened to me.

if ur really interested in doing this build on ur car..i got someone that is making a return fuek system for me and a few other parts..

but i have dezod turbo kit..but not the turbo it comes with..turbo cam, vs&r, and a few others..still need pistons, rods, ems. summer it will be done..

Some people have used the TSI fuel system with success, its not the better choice though, very primitive. The bare minimum to run these motors with boost is something like Emanage,PCS or AEM EMS + bigger injectors. Emanage being the cheapest and many people have had success with tuning and operating it. It is a piggyback so don't expect it do to be problem free dealing with your ECU. The problem with the stock fuel system setup is that it can only accomodate up to a certain size injector due to the closeness of the throttle body. I believe someone was able to squezze in 440cc into the stock rail. Another thing to think about is intake manifold, its plastic and CAN crack under higher boost.

My advise to you, if you want some one to spell it out?
-Get the emanage + all sensors that come with it
-Get RSX injectors
-Get the car tuned professionally by someone who knows how to use Emanage.
-8 psi is the sweet spot, you will love the power it makes
-You want more? save your money for engine internals or do a K-swap.


15 psi? You got alot of work and research to do padna.

i need a fuel line return , if you have one made let me know how much .
im very interested. i have had no luck finding fuel rails. what has everyone been using for a fuel rail?

 
Rep Power: 361

well someone is making mine like i said..and the person is using a stock fuel rail that our cars come with just modded..

 
Rep Power: 282

You don't NEED a return fuel system. But if you want to run high boost such as 15psi its needed. My advice is start small. Decide if you want to use the tsi fuel system or rsx injectors and emanage. Put on your turbo kit and and get it tuned professionally. Get a feel for how the car drives so you understand with what's going on when your boosting. I believe you will run into more problems before you can even think about turning up the boost. The t25 is internally gated anyway so do you have a boost controller. You will need to change the wastegate spring if you want more boost. 03-Acura-1.7-EL I believe is his name is using the tsi fuel system on his tsi kit pushing 9 pounds safely fyi. You might want to have a chat with him. Good luck.

Would Like To Hear From Some Members That Have The Tsi Turbo Kit
And Hear Some Positives Or Neg. Of The System . Would Like To See Some Psi Boost Some People Are Doing And Maybe Some Times From The Track Or Dyno Runs. Thanks To Every One Who Has Responded So Far. Great Info.

I had the TSI kit running 13-16 psi with the extra injectors and never had a major issues yes its almost max on that turbo but I may have been one of the fortunate ones also. There kit is a great little power out of the box solution but if your wanting more you need to get better fuel management , get rid of the TSI injector box and go from there. Going to a T3/T4 hybrid will give you more over all at less PSI also

 
Rep Power: 239

What Mods Did You Have To Take The 13-16 Psi ? And What Kind Of
Injectors?

 
Rep Power: 328

Im curious why 15 psi? Most people would set a whp goal not a psi goal. Psi isnt really anything to measure against.

 
Rep Power: 239

My 1st Goal Get The Kit In And Drive. 2nd Goal 250 Horsepower . Thats A Good Question. The Rep From Tsi Said Piston And Rods Can
Run 14-15 Psi Unknown Horsepower. So I Was Getting A Feel Of Other People On The Forum With The Tsi Turbo Kit And The Psi
Rating They Were Running And The Horsepower Gains To Match .

 
Rep Power: 328

Good luck on your project! Be sure to read and ask lots of questions. Some of the guys have already posted some very valuable info to help you in that direction

Here we go again....

TSI fuel system is good to 10-12 psi, after that headgaskets starting to blow up. Reason being as it cant compensate for timing.

At 8 psi TSI fuel system should give you no worries, and no you wont make as much HP as with emange. TSI will give you 5% or so less power because you cant "tune" much with it. But with this system you're getting dependability and good night sleep.

T-25 @ 15 psi with emanage will yelld appx 200-210 whp, whitch is below your HP expectancy, but requres no modification to the kit (not the engine, its is optional) what so ever.

To go to 250 whp, we are talking much more $ and many upgrades to the basic kit, to the point where you'll be better of selling whole tsi kit and buying Dezod's, or going custom.

Well if you're going to build...

upgraded fuel return
stage 2 turbo cams vs&r
dezod 8.8:1 pistons
rods
new intake manifold

and im probably missing a lot but i've never built a d17 nor do i plan on.

No One Offers A Intake Manifold That I Know Of Yet.
Who Offers The Intake Manifold Upgrade?

 
Rep Power: 282

Dezod is developing an intake manifold for forced induction now and if I'm not mistaken it's expected to be out this summer. So by the time you're ready to upgrade your internals it should be ready. Supermex a member on here custom fabricated his own intake manifold so that is always an option.

 
Rep Power: 328

There are a few custom intake manifolds, but be prepared to pay out the @$$ to have one made. Unless your capable of fabing one yourself? I suppose that you could make all the stuff for one then take it to someone to have it welded up, but still will be expensive to pay to have all those welds done
