ANY thoughts on this Modded K04 from Turbolabs?

[Arkangel77]

Check out the video - just wondering what you guys think. I am not looking to get this done but it looks like a viable option for an Upgrade to me, I have very little knowledge about this stuff though.

~$400 upgrade, 2-3 weeks turn around usually. Buddies car made 310awhp and 390awtq in his speed6 on e85.
I've also got one in one of my ms6s but haven't had it dyno tuned yet, still on an ots map lol

[Easter Bunny]

Not worth it. Not enough of an increase to justify the price. Bnr s3 or corksport puppy turbo is the way to go.

[derek13p]

This was awd and to the wheels on a dyno with no aux fueling.
With a ms3 you would for sure have better results all around.
It's also about half the price of a bnr and comparable performance to the CS.

[Arkangel77]

Well - I am for sure still learning but it seems like a budget friendly option to me.

[Dommo14]

Does anyone have data to back these numbers up?

All I got at the moment lol
Maybe I can get him to send a dyno sheet
Does 12.8 1/4s though

[GEE1989]

I wouldn't put it on my car. To each is own though.

Okay, imagine this, you have a Smokey k04, gotta replace it... Don't want to go as big as a BNR so you're trying to find a good k04. How much is a new k04? How much is a good used k04? I know a rebuilt and oversized k04 that can do 24psi w/o being maxed out is $400...

[Dommo14]

Its kinda weird that not many people on this forum, which is the Mecca for mazdaspeed 3/6 world, is using this. Mind you I have only been on the forum for a little under a year so I could be wrong but, until I see data and others installing this I am a little hesitant. At $400 this would be the best bang for your buck. Waiting for more info.

I would try it for $400 but don't expect longevity

[JakeMS3]

1. Cheap
2. Fast
3. Reliable

You can only have two. If it's cheap and will make you faster, don't expect reliability. If it makes you fast and is also reliable, expect to spend the $$.

[Easter Bunny]

Cs and Bnr are 400 whp turbos. This is a waste, the ko4 housing itself is the biggest restriction to making power on this platform.

VW K03 K04 Turbo Upgrade | Turbo Lab
Turbo Lab Turbo Upgrades for Audi, voltswagon, BMW, Mitsubishi, Subaru, Nissan, Buick, Mazda, and more.
They do turbo upgrades for basically anything. They are pretty well known by many performance shops. They don't "specialize" in k04s, and haven't done a whole lot of k04s for the mazdas but what they have done is damn good work on the two I've seen in person and improve on the factory designs. The k04 from them is a lot less likely to smoke than the OEM.

[speedfreak44]

The measurement is has for the compressor is as big as a s3 but still running the k04 exhaust side with no porting. I would worry about surge

I haven't experienced any so far. Probably have 7-9k miles on it and plenty of launches and pulls

Do you have a dyno sheet?

I'm on the stage 3 Cobb ots map. I just sent a spare k04 in we had laying around since mine was smoking like a mofo.
I text my buddy and asked for his dyno sheet though so I'm waiting on that. Same guy that I linked the video of earlier.

[Gnostic1]

My thoughts from a California resident, a modded k04 is sleeper enough to not need to be another component necessary to swap for smog and can give added performance. Not too shabby for 400 bucks if I can smog with it too.

[Dommo14]

How long have you had this?

4-5 months on my car.

[derek13p]

Okay, here are the exact numbers. Awd, on a dyno, 50/50 e85, cxracing intercooler, 3in turboback, 3.5 in intake, and the semiupgraded turbo.

[Dommo14]

Ok I am interested but I'll need to see how this holds up overtime.....

Can't be any worse than the k04 stock. Not that it's saying much ...

[Arkangel77]

Very good discussion on this topic! Thanks for all the replies and Input guys.

FWIW - if it only holds up as well as a stock K04 and it dose put out more power, then to me it seems like for $400 its a great option.

[Djohns]

Honestly for the mods and fueling I'm not immensely impressed. I've seen ko4s hit those numbers

[derek13p]

Fwd or awd?

Everyone around here is trading in their 3 for a 6 so idk of anyone running this fwd

Awd. Only difference was he was running a little bit of meth. But everything else almost identical minus the turbo of course.

[GEE1989]

Brand new k04 is about the same price as corksport and bnr. I'd rather spend 1000 once than 400 twice and have to deal with the headaches involved with blown turbos. At that end of the day, it's your car. Make sure they warrant it

I hit 305/372 on 93 with my k04. If I ran any type of E mix I could get much higher figures. I understand that is a dyno of a 6 but as far as being "upgraded" I would want more.

[jtday]

Not exactly an upgrade, but RPM is selling these now:

FTG addresses the issues inherent to our k04 and for $600.

FTG K04-882 OEM Replacement Turbo @ therpmstore.com


On the turbolabs: upgraded wheels are great, but if it doesn't address the real issues with the turbo, what's the point? You can see why it's only $400.

[Arkangel77]

let me ask this question, just for my education. Lets just go with the assumption that this $400 upgrade will net whatever (call it 40-50) more HP. What other options are there for that same $400 investment that will give you the same or similar increase in HP? If you feel like playing lets hear your thoughts =). If not that's cool too

O and PS - which of the options would give you the Most efficient power? IE - Best MPG =)

How about that for a stumper lol

Based on the dyno graph and info provided this is a $400 turbo that offer an increase of 0 whp over a k04

1. None of our cars are RWD, so RWHP doesn't really mean anything here.

2. Cobb AP and an E85 tune will get you to 300+ whp and 350+ wtq, no matter if it's an MS3 or MS6.

3. All can be made efficient. I get precisely the same highway fuel economy on my BNR S3 that I did on the K04. In town, it's all about how you drive.

Exactly. If this thing made 305awhp and 370awtq without E85 or aux fueling, I'd be more impressed.

My Mistake - I fixed it - just a typo

Originally Posted by speedfreak44 Lol there is no increase vs a standard k04. The power drops off hard past 5500 just like a k04. This may gain you 5-10 PEAK whp but that is it. This is not an upgrade at all

well - that seems like its kinda pointless than LOL

[speedfreak44]

[derek13p]

How much does it cost to rebuild a K04? Just out of curiosity.
And I'm sure with meth and or aux fueling this would do a lot better.
Either way, I got a non smoky turbo for less than $500

[speedfreak44]

I have rebuilt 2 k04s for less than $100 each and they worked fine

This will not outperfom a standard k04 just don't waste your money

[Arkangel77]

Speedfreak - when you rebuilt your K04's , did you try to seal the compressor side housing? The Turbolabs kit comes with an O ring but the stock turbo dosent use an Oring. I was wondering whay you did? Thanks man

[Arkangel77]

Well I just bought a Rebuild kit from Turbolabs and it cost me $45 SHipped sooo ....
