Im most probably will go for webcam, and adjustable cam gear. What is maximum hp people have gained with wilder cam (like webcam) and adjustable cam gear.
Head porting. There is no porsche specialists around here, can anyone give me a tip if there is something special compaire to other cars. I can find an experienced mechanic who could do the port job for me.

What kind of camshaft would you suggest? Is there any what I could still use on stock springs and hydraulic lifters?
Markus
Im thinking maybe one of those 2
PHT CS-19 for 944T
Best power band 3500-6800 rpm. 900 rpm idle. .474 cam lift (In & Ex) with stock base circles for drop in performance. Uses stock or 944 Turbo valve springs for best results. Motronic chip must have rev limit raised for best results. Up to 450bhp. Needs aftermarket engine management, larger turbo, larger injectors, raised fuel pressure, larger fuel pump. No equivalent competitors cam.
PHT 8SR/S3-14 for 944T
Best power band 4000-6900 rpm. 900 rpm idle. .503 In. cam lift & .475 Ex. with near stock base circles. Uses race valve springs. Motronic chip must have rev limit raised for best results. To 490bhp with race exhaust, larger turbo, larger injectors, raised fuel pressure, larger fuel pump. Needs custom Motronic chip or aftermarket engine management. No equivalent competitors cam. Used where lift is un-restricted but racing cam is allowed.
Is there any place closer where I could get one?
cheers

Call JME above and ask them, but I would choose the bottom cam. You are running a TON of boost, so low end torque won't be a problem. Horse power at the top will increase with either but more so with the 8sr. BUT you need to do what it says to prepare your head.

hello
If you are really serius about head work and camshaft you could get soem special stuu in geramny. No add on like in teh USA custom made for your car.
not cheap but it works.
for examble NA engine 1.4L 190 HP 10500 RPM won all championship and not opened for 2 years
2L turbo 600 HP
head work for my car 0.88 bar boost the results can be sen on the last video etc etc
He has an engine dyno but works mostly with Motec ECU

Performance Developments also offer a very professional cam service. I was told the CS-19 cam is not a good design for the 944, try Neil at PD, tell him your specs and goals. I am sure he can design you a good cam.

The manufacturer is him self togethter with some other very special race companies.
you tell me what you want how much you wnat to spend and I get you quote.
Normaly he makes only whole engines since he is afraid that somebody put thinks wrong togehther and he has to offer waranty .
He offers wararnty that his stuf works and works right.

hello
This is not a Port and Polishing job
this is race head preparation.
Other vendors like LR wants 3500 for this and do not even make half of it
The price starts from 500 for a standard job, valves, seats, planing the head etc to 4000 EUR for a full job
you decide what you want.
standard
performance street
full race (incl titanium valves , springs cams etc)
all work is made special for each car. you say what you have and what do you want.
He has no unlimited time sinc ehe has to make otehr race engines but if he has time between teh projects he will do that if I ask him.

OK It is actually simple, what I want
I want maximum out of my current turbo (what has been dynod 402 hp) @ 1.8 bar of boost =26 psi.
I want 500 hp at same boost level. It can be calculated how much stock head can flow how good is later model cam and Maybe it is just the cam/cam gear what needs to be changed but. Higher lift on the cam means also more porting in head right. How do I get that extra ponys out of that engine? Its only 100 hp

You don't necessarily need CUSTOM cam. If you have the flexibility to tune your management to the hardware, you will do okay - instead of buying a cam to suit the afr 
I am sure my brothers in Germany will be happy to sell you a ridiculously expensive "custom" cam, not dyno it, then laugh at your *** when you leave.
