my boggo standard 06 55 plate Mk5 GTi is going Stage 1 next month, but before I do this, I've been looking through some old threads, and I've noticed some of you talking about changing the standard K03 turbo to a K04. I've got a few questions:
Is this the turbo of the R and Cupra R?
Is it an easy swap, and what kit is needed to do it other than the turbo?
Would I need a remap as well?
Is it worth doing, or can the K03 be adapted now (I saw talk of not needing to do it,as there is now a hybrid?)
Are ED30's K03?
How much would it cost for the full conversion?
Forgive me if this has all been answered before, but the threads on this seem at least a year old, and I'm sure things have changed.
-
Ed 30's are KO4 and also have bigger injectors (i think).
And there is no need to change your turbo for a stage 1 remap...
Ko3's can easily handle a Stage 1.

I know my car can handle stage 1 with no other mods. I'm thinking that if I change the turbo, do I then need a remap, or will I have 265 bhp immediately, or is there a map that I would need to do as well? Or do I just follow the stages, and then change the turbo at the appropriate stage, whatever that would be?
-
Im not sure as to wether you get a gain in HP by just adding a bigger Turbo,you will certainly need a map to increase HP aswell as torque,depending on how far you going to take the car (Tuning wise) if your going to go towards the 270-300 HP route then it would be wise to fit the KO4 as it would be less likely to fail....
A bigger Turbo is more of a security measure if your adding horses hence why the ED 30 has the Ko4. (VW not taking any chances).
-
I've checked the Revo site, and apparently I can take my car to stage 2 with my K03 turbo, but if I want to go further, I will need to change the turbo to K04. That makes sense, as I may find I'm happy with the car at Stage 2 (Or Stage 1 for that matter, but knowing me, I doubt it!)
Still, one step at a time, there's plenty to do and spend to get to Stage 2!

Replacing the K03 with a K04 will include a relocating of the DV to work.
You can go K04 without changing injectors, i have assisted in doing that on an Eos which gave a result of 301 bhp and 450Nm (first Cat also having been removed)
Ideally you need S3/Cupra/ED30 injectors, a rebuilt HPFP that produces 130bar instead of 110bar, another intake and 3" aftermarket TBE and of course a remap utilizing these improvements.
That's about it really, now go get it done :evilgrin:
-
How do you know what turbo you have? my car is a 58 plate gti is it just the ed30 that has ko4?
-
^^^ Yeah just the ED30 with the K04
-
ED30/S3/Cupra/CupraR has the K04 :innocent:
-
ED30/S3/Cupra/CupraR has the K04 :innocent:
And the Golf R?

Thanks for that Danish! DV = Diverter Valve I presume, but what's HPFP?
Would you get to stage 2 first, and then do the above, giving the engine a chance to get used to more power, or just get the whole lot done in one hit. Also, do you have any idea how much this would cost?
-

-
HPFP is the high pressure fuel pump located on the right side of the engine when looking at it from the front of the car.
As to how to go about doing it all, guess it depends on how deep your pockets are... a good TBE isnt going to be cheap, neither is a turbo, or the labour unless you're doing it yourself... I'd also consider a brake and suspension upgrade if you're wanting more power to make sure the handling is up to it
-
You can go to stage2 + with a ko3 turbo
You will need
1- intake system- itg or twin take etc
2- full turbo back exhaust- Milltek etc
3- auto tech or apr high pressure fuel pump
4- UPRATED revision d divert or valve
5- UPRATED intercooler - s3 or forge twintercooler
6- stage2+ mapping
This shoul be good for between 280bhp and 295bhp depending on which hardware/software you use ( and whose rollers it's mapped on) mine was stage2+ with amd and made 295bhp and 320ftlb torque

If you are thinking of going to a K04 setup I might know where there is a good low miles K04 Turbo and a set of S3 injectors :wink:

I think it needs clarifying that a stage 2 on a Ko3 gti does not give the same power as a stage 2 on a Ko4 ED30.
Stage 2 on aKo3 car is about 280-300 bhp
Stage 2 on a Ko4 car is about 330-340bhp
thats if my memory is up to scratch.

In my garage lol.

if somebody has K04 full gti conversion kit with all parts to K04 or K04 turbo and S3 injectors I am interested

No prowling this time, just know mine will be coming off the car very soon :wink:

Thanks a lot guys, I'm going to start trawling the web to find out how much all of this is going to cost!
When I first joined the Forum in November, I said to myself that Stage 1 would be it, no more, but TFSi Mike warned me I'd end up bankrupt, and I reckon he could prove to be right! Can't wait to get going!
:signLOL: :driver:

Those figures sound high. I'm running stage 2 on a KO4 and it makes 290.

That sounds very low, what mods do you have? :confused:

Revo stage 2 with Miltek full TBE, k&n panel filter and forge dump valve.

Do you have an uprated hpfp as well??

No, will it make much of a difference?

At the OP,
There are kits out there at about £2000 plus fitting.
It is worth noting that the turbo and manifold (all one unit) is not that expensive from the dealers new.
-
would the ko4 make any difrence for a stage 1? or only realy come in to play wen your stage 2 +?

above post didnt quite read how i wanted but you get the idea, top 2 cars JKM have (had) seen one with Ko3 and one with Ko4, as you can see this the Ko3 is running stage 2+ software and makes 280bhp, whilst the ko4 car makes 330bhp on stage 2 software NOT + software.

Yes.
as said you'll need s3 injectors etc as well as the bigger turbo to make the best of it. The remap after is a must to adjust things like the injector pulse width's, they will be set up for a smaller injector so fitting larger ones will result in over fuelling.
