I have rebuilt my LDK, Molnar rods and Wiseco pistons.
How much boost can hold this config ?
I'm now on 25 PSI on my K04+
Thanks for the advice

I'm on 28-29, Tom I think is on 29. I'd suggest ask ZZP I'm sure they've pushed it farther than we would. It's plenty on 28psi on e47 on an S257.

I'm sure you can push it well into the 30 psi don't know how much that will help you with the +

Go do some research. More boost won't help.

But honestly above 27 won't do you any good. I have a + also and it spikes to 27 and fades from there. A bigger turbo you could go 28-30.

be more worried about the headstuds than the block itself. even my LNF was tested to 30 psi a few times on the EFR and still didn't push coolant.

I was running 28 psi on stock lnf for 2 years on 6758 before turbo went and I bought a built engine. now I run 30 psi on s257. well 30.5ish. so ya, 25 on a built bottom end is no problem. as long as ur not doing it on like stock k04 or something, which is not meant to run over 23ish, cause it just blows hot air and more likely to knock and do damage. I wouldn't run any more on the turbo u have
