3.0 to be converted to 3.2 Twin turbo

[VW 612 RS]

Hallo!
I wanna make a tread of my engine project.
The engine is a 3.0 -77 case 03.

Have bought a new set of cylinder and pistons from Mahle Motorsport.
This is a 98mm set for 74,4 crank and 23mm wrist pin.
Pauter has manufactured rods who works with 70,4 crank and 23mm pin and they are 1,8mm longer to remain 7.5:1 comp.
K16 Turbo´s from 993/996 as a start and will be changed for 24/26 later.
3.2 intake manifolds and I´m going to use this EFI system:

Will post pictures during the process
So here is the very beginning, not that clean yet.......

Testing the brand new 993TT oil pump with the new sump.

At last the engine building has started.
First step is to do a little better breather job






And some parts waiting for the crankshaft returning from the balancing job.

I thought I was good with a die grinder, but your scallops on the webs look machined.

Great job.

Just the original -78 3.0 heads.
Those with the larger intake ports.
They are a little bit ported and matched for the 3.2 brackets and intake manifolds.

You'll like those bigger ports!

Before and after.
Matching the intake ports for the 3.2 inlet system




P&C ready for assembly




Checking deck height

Timing of cams just for checking valve clearense to piston.
And then deassembly for mounting of gasket etc.

Have you looked at UMW K16/24 hybrid turbos?

No, I'm gonna use ordinary K16 from 993/996 as a start.
Because I have those for a long time. They are almost like new.
But later I'm gonna change to hybrid 24/26 turbos.
The have the same flange as K16 so I don't need to modify the exhaust system.

I will start with those just to start with smaller turbos and the grow later.
