so i have a fc rx7 turbo II with a POS engine and i was going to do a 1uz-fe swap but that didn´t work out but i have now a 3.7 v6 mazda engine , that it is in fact a cyclone engine from ford also used in the mustang f 150 and others, my question is has anybody worked with these engines before, i will be doing a twin-turbo setup with twin garret gt28´s , according to my research on stock internals it´s good for 450 -500 whp , with good examples of several tunes with vortech and procharger setups and stock internals doing under 500 whp, and that is a very good number for me. if anybody has worked with these engines and has any useful info please contribute
