to a point yes you are quite abit better off with a beams...
but even then you are chasing quite large numbers from a BEAMS n/a...you'd spent most your budget on buying the motor/aftermarket ecu and installation...
my question is...why do you WANT/NEED 130rwkw+?
if you are attempting to keep up with your nissan owning mates in the traffic light grand prix...sell up and buy a r32 gtr already..
