How far can you bore out a 4g64?

Can it be made into a 2.6?

The bore spacings are close together - the biggest you would want to go is 1.0mm oversized to 87.5mm. No way you could get it to a 2.6 without a 106mm stroker crank. A 4G64 is 2350cc as it is so boring it out will bring it closer to the 2400cc it's meant to be.

that would be nasty though serious DOHC displacement.

87.5mm bore and 106mm stroke with a small rod to stroke ratio would be a harsh engine in terms of vibration, and it would not want to rev out much (or do so without extra stress).
