All Rb25's from my understanding have the same boost set at 7 psi
it's what you can do with the turbo that is different, just because you have a neo you have to find out which neo you have, there are different versions that I have found out, aleast for the turbo
For this the easiest way is to take a look at the turbo and find out what the numbers are and if the compressor is single or dual fin.
after that get the numbers off the exhaust housing as well then look it up
hopefully you have the steel version and can be boost crazy with yours but for now don't go over 12 psi just to be safe.
you can also verify if you have steel or ceramic wheels just by using a magnet and testing them.
This is what I have learned with mine after reading about this from the last 6 months.
I have a Neo turbo as well...
Just trying to simplify all those threads out there on this subject so good luck!
