[TurboKraft]

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.
