Porsche Crest 3.4 Rebuild

Hi all after the devastating news from my new engine builder that my engine did not contain the parts I had purchased and gave to the previous guy to install in my engine. these include Pauter rods, new 3.4 pistons and barrels, knife edged crank ect ect ... So I am starting again cases have been shuffle pinned but now that I have to purchase the important parts again what should I go for...
Rods
Pistons and cylinders
Crankshaft..
I have toyed with the idea of going bigger cubes but what can I fit into 3.3 cases
I am after a tuff street only engine and I will retain flat fan and ITBs and the twin turbos.. I have an Autronics ecu and it will be mated to a G50 with LSD all this going into a super wide 930

Unfortunately for legal reasons I am not permitted to do so... but no need for anyone else to worry as he is not doing engines anymore...

Rods: Pauter or Carrillo

P&Cs: Mahle Motorsport 98mm (7.5:1) or we use LN Engineering "Nickies" with custom made lightweight pistons, any compression you desire (no base off-the-shelf JEs, no way) in either 98mm or 100mm bore

Crankshaft: stock 3.2/3.3 74.4mm crank is fantastic
If wanting more displacement, the GT3RS 76.4mm crankshaft is ideal, but requires different rods.
We've used this with 97, 98, and 100mm bore for 3.4, 3.5, and 3.6L displacement.

If you really want to go crazy, we can provide you with a GT3RS4.0-spec 80.4mm crankshaft.

We're doing a GT3RS+98mm + ITBs in HAMS930 for a displacement of 3.45L, aka "stroker 3.5L". Should be similar in performance to your twin turbo ITB.

Chris, Can you clarify the "No base off-the-shelf JE's, no way." Is this specific to 930twin's engine or more general?

I have a set of 3.5L Nickies with JE pistons, should I be concerned about running the pistons that came with the cylinders?

Thanks,
Rich

Sorry for the slight Hijack Porsche 930twin!
