Looking for opinions on what boost levels I should run rb25

[Marahutay]

Greetings guys! My rb25 build is nearing completion, and I need some opinions on what would be a safe level of boost to run on my factory fuel system/tune. I have a Precision 34/31E turbo that I know can easily surpass the factory injector capabilities, so I was wondering what would be the strongest spring I could put into my waste gate that wouldn't be risking any damages? I have a wideband to reference but I'm not familiar with the limitations of the factory tune on the r33 ecu. I am also running a z32 MAF. I planning on putting just an 8psi spring In, until I have the money to have it dyno tuned and I plug the haltech in and put in the 740cc injectors unless y'all think I would be okay with more boost than that.

Thanks for your time!!.

i wouldn't even go into boost until its tuned correctly.. surely wouldnt go above factory boost... keep an eye on your wideband.

A factory z32 maf on a 25 ecu will not read correctly, keep the factory maf untill your ready to tune but why not ditch the maf for a map of your going to be running a standalone??
