I can tell you what was in my motor.
JE pistons 98mm 10.5.1 comp
2.7RS cams
bored out MFI manifolds and intakes (Eurometrix)
Ti valves and retainers
Stock rods
bottom end was cleaned up for air flow
heads massaged
3/4" headers
care taken putting it together.

My view when building any porsche motor is to look at what the factory was doing in the period and try and use the bits that they carried over.

If you look from the 906 onwards they used MFI as opposed to carbs.

There is a guy that lives near me who has the same setup as I had except he had 3.4 capacity, RSR cams and a Kuglefischer injection pump. The motor was making in excess of 350hp. It was a pretty peaky motor to drive. I also understand the motor would rev to 8500RPM.

In my opinion the older motors can make a lot more power now than when they were being raced in the period. this comes down to our ability to access the modern technology in components. IE light weight pistons / rods / barrels ///

I am currently building a 2.3 litre ST replica and hope to acheive a power in the range of 230- 250hp flywheel.

We shall see waht eventuates.
