Turbo Troubles

**Vip3r** · 07-07-2016 06:48 PM

Hey all,

So I've come to quite an impasse with my 2007 a4 tip. My turbo is going down the tubes so I will have to replace it in the near future. Just some background on my car. Just passed the 147,000 mile marker woot woot!! So about 10,000 miles ago I had the entire cylinder head replaced along with cam chain and tensioner etc. I forget the exact Audi part number but it was a complete cylinder head. The engine runs like a champ now (with the exception of my turbo). I have a JHM stage 1 tune btw. So.... My options for upgrading as I see it are K04 or K0r. I've done some research on some other options but those two seem to be the main two. I'm looking for a decent increase in power but still able to be daily driveable. Any thoughts or suggestions would be appreciated as well as any personal experiences. Thanks in advance!

Im

around with a

APR KO4 with 230k miles. And I

the

out of my car. A KO4 from BW is a

choice imo.

If you don't mind hanging on for a few weeks, I may have a K0R I could sell if she's ok. My B7 just got totaled, and I'm not even sure what I want to do yet. Was installed ~90k and car was at 162k at time of accident.

Sorry for your loss. Are you going to part it out?

Thanks. If you visit the "What Did You Do To Your B7 Today?" thread, you'll see that 4 of us got totaled out this week, all grey.

Probably will part it, but I'm waiting for insurance to get situated and I need to get my C5 up and going this weekend (replacing all the seals, timing belt, water pump, etc).

**Vip3r** · 07-07-2016 07:57 PM

I am sorry for your loss. Yea keep me in the loop on what you decide to do. Hopefully my turbo will make it another couple of weeks idk 😑

If you want a daily driver why not get a smaller turbo, it spools up faster than the K04 hybrids?

You mean a stock k03??? Wut?

Op if you're going new get a k04. Don't bother with a k0r new.

**Vip3r** · 07-08-2016 06:35 AM

Thanks for all the input guy, I appreciate the advice from more experienced enthusiasts! It's definitely a big decision for some big money possibly. I love my JHM tune but if I really wanted to keep it I'd have to go with their BT kit which intrigues me but I haven't read of any tiptronic using it so far...

**DeathBlow** · 07-08-2016 07:09 AM

Why do you think your turbo is bad? I'm curious seeing my car is at the 115k mark and it seems to be ok. Is there any signs that are popping out at you to make you think its going? I have the JHM stage 2 tune on my Audi thinking of going to their BT kit.

**Vip3r** · 07-08-2016 07:49 AM

Well I got my JHM tune about a month ago, maybe a little longer. I immediately felt the difference it's awesome. Over the past week or so whenever I accelerate and the boost kicks in I hear either a grinding noise or like a high pitched squeal/whine kind of noise. And imo the car hasn't pulled as hard the past week as it used to. I originally thought it was the serpentine belt squeaking but now I'm pretty sure it's not.

**thenofjboy** · 07-08-2016 08:39 AM

ahh grinding sound is no good obv. got a boost gauge? if so, any change in PSI from when you got JHM up until now?

**Vip3r** · 07-08-2016 08:46 AM

That was next on my purchase. Was actually planning on getting one last weekend before the noises started. I definitely feel a difference. Not that I can definitely tell the PSI change but I'm pretty sure there is. Used to pull harder than it does now.

That's what a k0R is man. A k04 chra crammed into a k03 housing.

You're confusing older chassis turbos with the fsi/tsi turbos. They're not the same. An fsi s3 k04 spools around 2400rpms.

My opinions on

.

Options #1 Get a rebuild kit on e bay for 30.00 and

yourself. But if your hear grinding noise. Id think about it since you mite have damaged the turbine wheel or housing already

Options #2

the unit and send out to http://timsturbos.com/ he

these for about 375.00 and comes with warranty
turn around time is 48 hours
Options #3 buy a used turbo of the classified for about 350.00 no warranty period
Option #4 buy a brand new turbo from https://www.europaparts.com/turbocha...6d145701j.html $1000.00
Option #5 go KO4 but you will need supporting hardware and software. Youd be all in for about $2500.00 with selective choices

luck with

it

**Vip3r** · 07-08-2016 11:25 AM

Thanks for the advice. That's what i thought about the grinding too... Probably will either just get a new turbo or go K04. Just trying to decide if I go k04 do i go with apr and if so that would mean I lose my JHM tune as I would have to get the APR k04 file correct?

**thenofjboy** · 07-08-2016 11:34 AM

JHM is working on a KO4 file...not sure when it will be released though

**vce1232000** · 07-08-2016 11:35 AM

No. JHM also has a KO4 tune

. I think you can upgrade into it for a small fee since you already have the JHM satge1 tune

. I purchased the JHM KO4 tune. But I havent done the PITA data logging for them to release it to me for use. So I can not comment how good it is over the APR if it is or not

. They ask you to do pulls from 3rd gear @ 2000 rpm to redline. I just dont feel like losing my drivers liscense to do the logs. As those pulls will bring you

up to 105 mph And Im Tiptronic transmission making the pulls more difficult since I can not wot easily with the kickdown engaging in

Good info, thanks

**Vip3r** · 07-09-2016 08:21 AM

Okay so this is the noise Ive be been hearing I tried to do some trouble shooting this morning. It's coming from the left side of the engine bay ie: turbo side. Any hints on what this noise may be? Sounds like a cricket kind of noise which leads me to believe it's turbo related. Appreciate any advice or help. I will be trouble shooting throughout today.

Bump. It only happens when accelerating and around 2000rpm then goes away

**Charles.waite** · 07-09-2016 10:46 AM

Apr's tuning blows nuts so I wouldn't even consider them. I believe it was apr's k04 tune (which I'm pretty sure they don't even sell anymore anyway) that was somewhat notorious for throwing rods through blocks.

Either way I wouldn't trust an older k04 tune. Back in the day tuners really didn't have a handle on how to safely get power from the FSI motors. I would absolutely talk to JHM about getting their k04 tune. It's not released to the public yet but I can guarantee its better than APR.

**Vip3r** · 07-09-2016 11:32 AM

Yea I'm in agreement with you. I love what JHM is doing with our platform and is the rest of their products are like my stage 1 tune I'm all about it. This pesky little noise is getting me pissed off trying to find it. I think it's the turbo but it's tough to tell

For future reference:

In USA (and other countries that drive on the right):
Left side of car = driver side.
Right side of car = passenger side

**Vip3r** · 07-09-2016 12:03 PM

Whoops sorry haha will note.

Kind of hard to believe that the APR was bending rods

. Its the most conservative

tunes out there on any platform. I know of many other custom tunes that was bending the rods from the torque curve spooling to soon instead of a gradual spool to avoid that torque spike that would cause the rods to bend. That why I purchased the JHM KO4 tune. To have update software. Maybe one day Ill be able to write an opinion on it

. Once I get around to data logging my engine.... So it gets released to me

Those won't fit in a 2.0t turbo housing. Just because it says k04 doesn't mean they're all the same.

So an entire turbo is in store for him or is there a Ko4 Chra that'll fit the Ko3 housing?

Don't think there is anything plug and play for k04 sized stuff unfortunately. You can get the housing machined for a k04 but that's not as simple as it sounds. Unless you find a shop that knows how to do it for the k04-64 chra.

When the boost is increase by a tune, the sound of the additional air mass being sucked into the intake often sounds like a rough grinding noise, it is only the aerodynamic turbulence of the increased air flow into the engine.
