What is needed to fit a GT25 turbo?

**mnkyA4** · 10-25-2004 10:39 PM

I was wondering what else is needed to install a GT25 turbo onto an A4. Is adding a GT25 the same as getting the APR SIII kit? Just asking cuz I don't really want the FMIC or exhaust, just the turbo and manifold.

**Rieger_RS4** · 10-25-2004 11:29 PM

biggest problem is the software

**skene** · 10-26-2004 07:14 AM

biggest problem is money.

**MKGIY** · 10-26-2004 07:29 AM

So you want to run just a GT25 turbo and keep everything else stock?

lol i think thats what he said.

I wont go into it.... but someone needs to do a little bit more research.

**DarkkstaR** · 10-26-2004 08:05 AM

but you dont want the FMIC and exhaust...

you might want to learn a bit more about turbos and your stock turbo system before you try to go about major changes to it.

you can't use the stock intercooler for many reasons, one being its flow limited and designed for a turbo smaller then the one you want to add.

stock exhaust on anything bigger then a ko4 = retarded :)

**skene** · 10-26-2004 08:07 AM

being flow limited?

what does that have to do with it.

you can still use it...

keep in mind a larger turbo runs lower air temperatures vs a smaller turbo.

**MKGIY** · 10-26-2004 08:13 AM

The stock SMIC would get heat soaked faster. I have seen people with stock exhaust and bug turbos. It works but not to the fullest potentail.

Moving this now....

Uhm, are you handicapped in any way shape or form?

You can't run a stock SMIC on a GT25, end of story.

BTW is that your face in your sig? If it is, I will laugh hard.

**mnkyA4** · 10-26-2004 10:50 AM

hey guys, thanks for the input. I know I will need a exhaust soon. I'm just debating which one to get in the future. As for the SMIC, some of the S4 guys that I hang out with and I and I are trying to fabricate either a RS4 IC or doing a dual S4 IC set-up. This is the reasoning behind just wondering what else I would need.

**DarkkstaR** · 10-26-2004 02:28 PM

What you need:

1. exhaust manifold
2. gaskets
3. oil line modification
4. the actual turbo
5. inlet pipe turbo to air box
6. injectors
7. 4bar fuel pressure regulator
8. software/tuning
9. exhaust
10. intercooler (interFOOLER if you like the ryyyce ;) )
11. MAF sensor

thats all I can think of off the top of my head, I'm sure there is more.

**mnkyA4** · 10-26-2004 04:47 PM

any company that has software? Or do I have to do my own tuning? If so what program will let me?

**EVIL-AUDI** · 10-26-2004 06:46 PM

You'll have to go to a tuner for software.

**EVIL-AUDI** · 10-26-2004 06:48 PM

BTW that is David Copperfield in Skene's sig. It's a NJ crew inside joke.

What MKGIY said...
I talked to APR about running the Gt28RS with the Stock SMIC and they said you can do it but you will get Major heat soak.

Will you laugh as hard as I did when that guy told you that you looked like you were 12?

**DarkkstaR** · 10-26-2004 07:22 PM

i'm laughing like apr is when you don't get your stage 3+ for another 6 months :P

no need for a new mani you can run the turbo with the stock mani using a turbo bracket.

**EVIL-AUDI** · 10-27-2004 07:39 AM

^^ That would be a big mistake ^^

I ran a SMIC with my T28 for over 6 months. So it can be done. Also I dont get why people want a BIG turbo but dont want to upgrade other parts.

Apparantly not, AWE is running a GT28R with the Stock Mani on their Stage 3 kit, and from what Garrett said the car is making good power. While I agree a bigger manifold would be better, especially up top, the stock mani actually has good flow. Like you I would rather run a bigger manifold. They will be offering an upgraded mani after the initial release of their Stage 3. Do you know any B5 guys that ran that turbo with the stock manifold, and what results they got?

**G_A4** · 10-27-2004 09:44 PM

from what mike over at AWE told me they are making a kit that bolts on to the stock mani. the turbo they are using is a GT28R and apperently it's making loads of power. so why would running a turbo braket with the GT25 be a mistake? i know that a better flowing mani would generate more HP and make more power up top, but really is it going to be a mistake to run the turbo using a braket? do you know something we and the guys over at AWE don't. well, if so please share.

**MKGIY** · 10-28-2004 06:45 AM

Is the AWE kit for the B5 or B6? Is there a big difference in the B5 and B6 manifolds? We all know that an aftermarket manifodl will be better and that is why AWE will release on shortly after.

It's for the B6, but I believe it's the same setup as the Garrett kit for the B5, see link below, no big difference really, the manifolds are exactly the same. Some of the hardware will be different, intake snorkel, etc. I believe they are using the stock MAF as well, not sure yet. Totally agree with you that a bigger manifold would be the way to go. But they seem to be making good power with this setup 290CHP is what I hear.

**MKGIY** · 10-28-2004 07:57 AM

More power to AWE if they can pull off those numbers and that kit is real cheap on that site.

Mike

**DarkkstaR** · 10-28-2004 11:24 AM

That would be nice. I dont want to see B6 owners getting ****ed because B7 is soon to be here and the tuners will jump on the 2.0T :)

**A4Rob** · 10-29-2004 08:54 AM

It is fine having a T-28 with no exhaust or FMIC. THere is a local guy here in mn that has it. He only put 222hp down to the wheels but I find that impressive for stock exhaust and IC

**Jrunr** · 11-06-2004 09:14 AM

Yes, but what about kits for the b6... is there ANYTHING worth while?
