what are my options?

[j30-tsi-awd]

hey guys whats up?

Alright heres the deal.
I was driving to work today, and I noticed a strange moan almost coming right before I hit boost. This was at about 2700-3000 RPM, and about 5-7 VAC. Then when I get on it, it makes a high pitched whistle at around 10 psi. There feels like a major power loss.
So im guessing that my t-25 is going bad. Im pretty sure that its the original turbo and it has, 180,000.
My 1st question is. is the t-25 going bad?
2nd What are my options on a new turbo?
I have a new jasper motor. stock fuel system, Greddy type s bov. Nology hotwires. and a N1 downpipe and N1 catback. i have a turbo xs dual stage boost conroller but i need the harness for the siliniod to make it work.Theres my mods.
What do you guys think my options are.
Im thinkin a small 16g ,but im totally not sure and I will consider pretty much anything. I Would kinda like to keep it the stock fuel system. I also still have the stock smic so id kinda like to keep that. I dont plan on taking my car to the track. Its my daily driver, but i still want to have to power as my disposal.

thanks for all your imput and help!

take off the intake and check for shaft play/bent or broken compressor blades.

180,000? Damn, surprised it lasted that long.

For a turbo, a T-28 or a s16G should be fine if you want to keep the stock fuel system.

Do you have a boost gauge? How many lbs?

 

[DSMark]

I'd say go s16g just because the t-28 carries a hefty price tag.

 

[j30-tsi-awd]

Hey

Ya I did that just after I posted. Umm how much play is to much? It moved up and down some and left to right alot...like id almost say 1/8 inch. I think it was pretty considerable. Thier was also oil in there
Yes i do have a boost gauge. Its a Autometer. What PSI? Like do u mean the highest the guage will read? If so it reads 30 PSI.
Ok, so if I choose to go with the s16g I would also need to order the install kit, with the new lines and the j pipe, correct? Any ideas as to how much more power I'd be making with the s16g?.
My car has also been overboosting to 18-19 PSI. I am still on the stock boost controller.
I did a boost leak test. I did'nt fine any leaks. So maybe the overboosting is related to the turbo going bad?

thanks for your help keep it comming!

gotta luv that shaft play trick! Make sure you move it up and down & in and out for a full check.

I believe that your turbo seal is shot. What I meant was how high is the boost when you get on it. 18-19 is too much for the T-25. Yes, you will need the install kit. You'll make more power with the 16G, but how much depends in the solid tuning

 

[j30-tsi-awd]

Hey.
What do you mean by turbo seal? Like the turbo is blown?
Ok so im looking at getting this http://www.turbochargers.com/store/product_info.php?products_id=186
Will this work? Will this allow me to keep my stock fuel system and intercooler?
Is this everything I will need to get the job done?

ALSO. Is it safe to drive the car till I get the new turbo on, if I stay out of the boost?


Thanks for your help. please keep it comming!

Don't get that Kit. it is a knock off Evo 3. (Get it from a respectful shop)
It is not the real thing and won't last long.

You can keep your stock Intercooler and stock fuel as long you don't get crazy with the boost (No over 12psi I would say)
You need the installation Kit for the 16G but not for the T-28.

Drive it with a blown turbo might bring you problem. So I would say no. (Is it burning oil? white Smoke)

 

[j30-tsi-awd]

hey
Ok can you guys recommend a "reputable" shop then? I saw this one on another forum page here on dsmtuners. They suggested it?
Yes to the white smoke...but i dont have a cat on my exaust either so im not sure?
It is not burning any oil.

keep it comming

Look at our vendors page. My personal favs are Buschur and SBr. I also recommend going with either a big or e3 16g Reason being is that you can still run the stock fuel sytem aslong as you keep the boost down, and you have the abillity to make more power later. Plus the small is the same cost as the big and more expesive than the e3.

 

[j30-tsi-awd]

I checked out Bushchur and SBr. I like SBr's stuff alot. So your saying just go with a big 16g?
How much more flexability will i have with the small16 vs the big16 vs the evo III?
SBr's 2g "total solution" is kind of apealing. I just dont want to get a turbo and not be able to use it without overhaling my fuel system. Maybe eventually, but right now. I cant afford it.
If I were to get the "total solution" kit could i keep my stock fuel and intercooler? if ran it at 14-15 PSI?
What kind of power am I gonna see out of these 3 turbos? I dont want all top end. or just super quick spool, somewhere in the middle is what im looking for.

I would suggest looking at an FP BIg 28. It has just as much potential as a 16g but it will botl directly in place of your T25, no modification required and no rip off install kit.

[j30-tsi-awd]

Interesting.....Thanks syndicate...I kinda like that as well.
what are pros and cons of the t28? vs the 16g's? How will the stock fuel hold up to that?
Im really considering the SBR "total solution" package.
Im very worried about the fuel system though, thats a big turbo. On stock injectors and fuel pump. Is it safe? what PSI can i run it at? Do i need anything else to get boostin again?
This is great keep the feedback comming
It its greatly appricaiated.

I ran my small 16g on just a 190 pump for a long time with no ill effects. about 13-14 psi is safe, just make sure you watch your IDC's and timing to see knock.

Pros and cons? The T28 bolts right in, looks stock if you have asshole cops or emissions and will do just about what a 16g will. When you decide to go bigger, and you will, you can move to something with some real balls. The T28 will make a great driver car and get you some experience under your belt.

 

[DragSourceTsi]

A T-28 will go low 12's with suporting mods. They are great turbos and can be almost directly compared to a 16g

 

[j30-tsi-awd]

URGENT!

Alright guys I think Ive made the choice Im gonna go with SBR "total solution"
-Evo III 16g
-2G Install Kit
-New SBR DSM Cast Manifold
What do I select for the porting options and the wastegate option???
I need last minite suggestions. What PSI can I set this kit at, to run with my stock fuel system and side mount? Im also considering getting SBR Fuel Mod. Package
it comes with
-Walbro 250
-Injectors of your choice ( 550 650 750)
-Apexi AFC II

ANY THOUGHS OR IDEAS AM I MISSING ANYTHING???

The Evo3 is a great turbo and will take you far. However I would advise against the fuel kit. The AFC is a POS. Now before someone comes in and says "so and so went 10's on one" it still doesn't mean it's the best way to do things. I would get a fuel pump for now and save some money for DSMlink. Your car is a 95 and should have an EPROM ECU, DSMlink is hands down the best money you can spend on your car. Check it out at www.dsmlink.com

<---Another very satisfied DSMlink customer. Since 2004!!

 

[supermariobros]

I was in the same boat as you not too long ago, I still have my stock fuel system and I got a big 16g because my 14b was blown. Its set at 12lbs of boost and is fine for daily driving. When you can afford it, get DSM Link and then a 190lph pump and 550's and you can turn up the boost when you can afford it (whole setup should run you $900).

Let me tell you something If you use 255 (fuel pump) you need to get an Air fuel presure regulator. (it is a must because you will overrun the stock regulator). If you get a 190 (fuel pump) you can't have injector bigger than 650cc, it is overkill setup.
If you have the money get dsmlink. but in the mean time you can get 255/650cc/Safc/AFPR

A question: Do you need to get the Exhaust manifold? is there something wrong with yours? otherwise save that money and use it for something else important.

It is a knockoff that has performed better than an MHI EVO3 16G. Look here:

http://www.dsmtuners.com/forums/showpost.php?p=1833061&postcount=6

To the original poster, look at the most recent threat about this turbo. It is much more objective than the bashing BS threads that have come and gone... and got locked.

I'd say go s16g just because the t-28 carries a hefty price tag.

Don't foget that any MHI turbo (14b, 16g, 17c, 18g, 20g, 24v, 25g) needs an additionall instal kit for your 2g.

I understand, But why take the risk? If you have money sure. But most DSM wouldn't want to be expending money on turbos every 2 months or so....

Anyone can run the stock fuel system with any turbo as long as you stay under 14-15 psi. I can run my 60-1 with my stock fuel pump and 450s at 15 psi !

You need an adjustable fuel pressure regulator with your 255 fuel pump. I did. Everyone I've ever talked to wi a walbro255 in their dsm has needed one.

750s and a piggyback (SAFC) don't mix.

A piggy back is a device that works with either an eprom ecu or a non-eprom ecu by intecepting the signal from the mass airflow sensor and manipulates the signal so that the ecu thinks less air is coming in. Thus, the ecu dials back the injector flow allowing you to install larger injectors. This has the sideeffect of causing the ecu to operate on a more aggresive timing map that is meant for the smaller amount of airflow the ecu is seeing. This can be very bad once you go really big on injectors. A rule of thumb is that any thing below 650cc is ok with a piggly back (no typo). Often times guys still cant get a good cruising and idle tune with a piggly back and upgraded injectors because of injector deadtime. With an upgraded injector, more often than not, it takes longer for the electric puls to open it to put fuel in the engine. If this deadtime is not calculated correctly by the ecu then you have a hard time getting the right fuel mixture to idle and run part throttle.

You will have serious idle issues unless you are a sharp tuner and can tune out the dead time for 750cc injectors... But it is very possible.

Do you know how crazy high your timing will be? Knock, knock. Who's there? Your blown engine. Compensating for the injectors with a piggyback means that you are fooling the ecu into thinking that you have less air flowing into your engine. That consequently causes your ecu to operate on a more aggressive timing map.

It is possible not to blow your engine with really high timing throughout your revrange. It is possible to tune out your injector deadtimes. Ask yourself, "How good of a tuner am I?"

You can get this "kit" for substancially cheaper if you fish around for the parts individually. I love SBR and have given them thousands of $$$ in business. But, these parts can be gotten cheaper individually if you look.

 

[j30-tsi-awd]

cool, thanks for the imput. I ordered the "total solution" package and the fuel packager as well. i got the 650 cc injectors with it. whats this I hear about a fuel pressure regulator???
im kinda confused


thanks
