I finaly managed to do things the way I wanted.
K03 turbo on a european d15 vtec-e.
I did things the safe way so I used 660 ccm injectors, chrome, LM-1 O2 and walbro 255 to make shure I do not get in to lean area.
The first manifold I made was custom and it worked fine but it started to break so I replaced it wiht HF.
The IC is from Saab.
BOV no name "racing some thing from local tuning store" works prety nice.
I rined the car on 12-14 psi (0.9bar) on the 402 Race in Zagreb and I managed to hit 14.6 best time.
The car was pinging like crazy and I blew my headgasket. Any way I decided to raced to the end. It held and nothing blew.
After instaling thicker headgasket things were beter.
I never got it on the dyno so I am not shure about the HP.
The clutch is sinter and it holds great.
The spool of the small turbo was great. After 2500 I got boost. I was steady all the way to 7000rpm.
Prety nice for town driving.
I changed the gear box to d16z6 but I destroyed the dif. Some thing got broken so It was back to the log gearbox.

HOW DO I GET MY PICTURES TO SHOW IN THE TOPIC

 

How soon does that little turbo run out of steam?

 

is the K03 the one fitted to audi TT's? or is it from a 150hp vag engine?

How do you control the 3rd stage of vtec in crome? Are you running a 2.5 bar map sensor?

 

K03's are from a VAG 150hp 1.8t motor. TT's, GTI's and Beetle Turbo S have the K03s, which has an
improved and slightly larger compressor while using the same turbine still
with the same installation dimensions.

 

yeah, those are designed for peak torque at a useable rpms on a 1.8l so on a 1.5 or 1.6 itll probly reach full spool before 3k.

Yes it is the 150hp turbine. Euro vtec-e has normal vtec that engages at 3800rpm. So the tuning is normal.
Before 2 months i swaped the d15 engine for d16z6 so now I am runing 14psi (it is winter here)
The car runs great. I tried it on open turbo boosting about 1.3bars and it held. The car was riping through 3ird gear like crazy until the hose let loose. Now I am leanring how to tune with LMA-3 and LM-1 so I can prepare the car for race. I will run Crome on max boost. I hope to hit low 13 or atleast 13.5. Now on 0.8-1bar I am at around 14sec on 1/4 but the car is not fine tuned yet.
