Here is a VF34(left) and GCG GT2871 (right) Mao is fitting on a GC8, they didnt take photos to compare my VF48 and my GT2871
. The turbine housing is similar size but compressor is bigger.
Like Nick's 1.5XTR, car lost mid range punch, and power becomes more linear running 1 bar. My plan is to slowly increase boost until my knock analyser sees knocking, then run a few settings below it, ie daily, track and drag.
