We are talking different worlds here Patrick 
My main goal was to use (cheap) stock bottom end and that means 2.5 liter. Any modifications like sleeving the block etc would make the engine immediately hi-budget.
Though 16v+turbo usually do not mean budget at all...

This is perfect imho. I have talking about building a similar build, but i haven't been able to find a 944s head. keep up the great work and keep us posted. Do you have more pictures of the motor?

Have you asked Luis, Carlos? Be good to see someone else give it a go too.

Finishing the intake next week and than the IC, after that there will be a lot of time with cabling and sensors..

This build would be pretty easy for me as i already have all of the custom parts needed. I just need to do minor modifications to the parts i already have, but nothing that would be break the bank or require anything special.

If you are interested in the bare head, let me now. I was thinking $250 was a pretty fair price, if you don't, let me know what you think is.

I am always worried about the tensioner area on 944 S and S2 heads (should be reinforced on 968 heads).
I was planning to go dual exhaust cams and dual cam pulleys but that would most likely require cutting the hood for intake pulley so decided first to start the car with original setup and then see how could I make it fit. Probably will make all custom pulleys with a bit smaller diameter based on the belt I can find. Not a fan of custom wear items so belt has to be production item from some other car.

Well.. I would like to see the progress on that! Because that will make me go dual cams as well.. 
But the tensioner area; i'm curious about the reinforcement! I know Michael Mount has build a girdle for the head for Henk's 8000rpm N/A engine.

you will of course have to get different pulleys - the original ones will touch each other as the offset of the two camshafts is too small.

Haha, sorry Bas, missed your post.
These are from VAG FSI engines, fit well but are a bit longer than actually needed. I got them from a friend who had them laying around, these are later revisions.
But actually COP's from 6.0 W12 engines are pretty much perfect fit, did not want to buy them from the dealer for 30 euros a piece. I am a cheap guy you know and this is a budget build
In reality there is no obvious need for COP ignition but on 16v engine they look cool and since I do not aim too high power levels, these work well. ]

Can you verify this?

Yep, seems to be the same.
Yes, I am aware of that. By original setup I meant that with single pulley and chain between camshafts.
