Hello. How much boost can make a K03 and a K03S turbocharger? My default map has about 1765 mbars (~0.7 bar boost). Now i`m running with about 1 bar boost at sea level and my goal is 1.3.
Here i`m talking about peak values at high rpm.

Most stage 1 files do 1.45-1.5 @ peak with the default WG

Stage 1 means how much bhp?
Will hold a K03 this boost without blowing up?
I`ve read that ~20 psi is best that K03 can do without damaging.

Hi,
I set the below boost profile in Stage 1+ software with K03s
3000 1.5
4000 1.8
5000 1.4
6000 1.25
7000 1.1
MAF counts 202-205g/sec
You will need 380cc or bigger injectors
MAF case S3 is optional
NA intake cam is optional
IC is a MUST
full 63.5mm exhaust (70mm dp is an option but will cost you to loose some low end torque)
I prefer the installation of a new wastegate actuator with a much higher preloaded spring (mechanical boost @ 0.85bar is fine)
In the dyno I follow this boost profile I wrote earlier
dyno car specs
WG aftermarket
injectors
MAF case S3
NA intake cam
IC
Forge intake hose
Forge 007 DV
100oct
software optimized for 100oct

Thank you for your reply. i don`t want to spend too much money on the car. i want only to take best from current hardware.
How much bhp can get from this profile with stock injectors:
3000 1.4
4000 1.6
5000 1.3
6000 1.2
7000 1.1
All this with stock turbo (on my engine code was both K03 and K03S, so i`m not really sure wich i have fitted).

with 100oct fuel optimization
stock inj & stock fpr
215hp
stock inj & 4bar FPR
245-250hp
You cannot run this boost profile you said with stock inj. At least you will need a 4bar fpr

Ok, so, for stock injectors and 3 bar FPR what`s the most agressive setup that you recommend? But for 4 bar fpr?

i swear that i'm not trying to be an ass with my response here, i'm totally serious:
everyone that has asked this question has ended up replacing their turbo sooner than later.

Yep. Matches my experience as well. Also, the kind of person who asks is invariably the same kind of person who ignores the responses. |

He's right.
I'm convinced mine is about to throw it's toys out the pram. It doesn't boost cleanly now, and surges really badly. Replaced usuals - N75 (it was showing a low duty cycle), plugs, coils, MAF.
Actuator moves cleanly. Was going to pick up a K03s hybrid done by Dan on here, but didn't have the funds. Decided that I'll make it look pretty, and make it go fast in the summer.

I`m pretty sure you are wrong about me My other car is an Opel Astra G with turbo diesel engine. The turbo was hybrid (failed in a saturday night and all that i had was few turbos from Volvo and Vw, but that`s another story). i`ve made one turbo from parts i had and worked fine for 6 months when i`ve replaced with OEM turbo that i`ve picked up from a friend for free. I know what is a surge and a lot of theory. In daily manner i`m a programmer and on weekends i`m a mechanic (repair failed engines). Reason why i`ve asked fotis what he recomments is that i know he knows way much about those engines/turbos than me and i want to make a clean map for my engine, but same time to have enaugh extra performance. To achieve my goal i want to start from original map and increase performance almost at the upper limit with stock internals because 402m racings are not my goal. |

If someone told you that with this boost profile the turbo will live for 100.000+, then he is a terrible lier. No doubt that your turbo will be killed 50.000klm with hard use, and may be earlier |

What is WG crack pressure for this turbo with stock spring?

What do you mean by crack pressure? Point of failure?
