I've recently since discovered i no longer have 34 n1 turbos in my car, the only thing that is partly the same is the rear turbine, and whats left of the compressor cover..
they are now more like gt2871r, with a 71mm front wheel in a .42 compressor housing (they should be in .60 housings) machined to suit..
still hopefully will net me somewhere around 400-450kw @ 1.7-2bar hopefully i wont need to update the compressor housing to something bigger. i guess it will only be something holding back top end power.
