You got me worried for a moment so had to do some searching and digging on the forum just to confirm
Because when I bought them, I did not check the impedance of the injector.

Rolling road - results
So today we had a rolling road gathering arranged by Audiclub.dk
The results where fine I guess 367 HP at 5788 RPM and 489 NM at 4121 RPM.
Did some logging while I was on the rolling road with Zeitronix.
First the boost curve, I'm using eboost2 and RPM setpoint which means the curve is programmed for every 500 RPM. Looking at the curve now, I should properly run the same setpoint from 2500 RPM to avoid that strange bump on the curve at 3300 RPM. Currently my boost curve programming is close to this:
500-2500 RPM = 23 PSI
3000 RPM = 23.5 PSI or something'
3500-5000 RPM = 25 PSI
5500 = 23 PSI
6000 = 21 PSI
6500-7000 = 19 PSI
Next is lambda and AFR and it seems that this a bit all over the place Anyhow at takes a nasty dive at 4500 RPM which at goes down as low as 10.7 AFR. So need to get my *** to Sweden at get the fuel sorted. That should properly give me some extra horsepower
Last is EGT which seems to be very fine but I guess that is due to the amount off fuel
Here is the Zeitronix file if anyone wants to have a look.
You should be able to download Zeitronix software free of charge here.
Here is a couple of measurement containing the same data as above made in 4th gear on the highway on my way down there.
Data 1
Data 2
Some pictures from the event can be seen at this Google Picasa Album.

Status on project 450
So here is my new K26/k27/K29 turbocharger
It is from Ultimot.de more specs to come.
Also ordered H-beams from Aronmatic

The price was right I guess, got it for 850 euro and it is brand new.
I did consider the GT3071R, but at 1800$ + shipping and tax/vat (in Denmark this is 30% and includes the shipping cost) the other seemed a cheaper alternative.
Plan is to use VEMS, but this is a winter project so I wont get going just yet. But VEMS is basicly the last thing I need.
I need to get the fuel sorted on the current setup and enjoy for the rest of the season
Just invested in a map sensor for the fuel pressure from Zeitronix, so I can see if this is what is causing my rich running.
But I do know that KKK is old school but I kinda like that
Originally posted by A80Avant View Postwith the #6 hotside, you will get better spool up time, but i wouldnt think more than 450hp because of hotside backpressure and EGTs
how come you decided to go for such an old tech. turbo though?
are you going to run VEMS on that?

Is this all I need for 430 HP
So currently this is my list for the 430 HP mark:
K26/27/29 with #6 from ultimot.de which should be able to push 430 HP with ok spool up.
H-beam rods with APR 2000 bolts - From Aronmatic
Bosch Light green injectors - From a shop in the US but they are dirt cheap.
VEMS
But what else do I need?
Plan is to run 1.9 bar to around 5000 RPM and then let a drop off.
RS2 rod bearings
- Lower yellow 034 105 701
- Upper yellow/purple 034 105 701 B
Do I need to lower compression ratio or should I be fine on stock Compression ratio with RS2 head gasket?
What about crankshaft bearings should these be changed as well or are stock 3B ones ok?

du er tossig når ikke at blive færdig med den ene ting inden du skifter igen,er glad for dit valg af lader er jo selv kkk fan
vi må snart finde en dag til at mødes,hvad med rs2 knaster og portet top,når nu du er igang
vil nok sætte nye ringe i da den bliver skilt helt ad og husk at tjekke oliepumpen,lad den ligge badet i olie ellers er den færdig når du samler igen.
Vh.
