I've been looking at sending him my current 72 4094 to have the 71 turbine and lots of porting and vane work done to it, has anyone ran one of his turbos or had any luck with them? He is a very knowledgeable guy and knows his bearings/balancing. I believe he calls it the 71 monster. 71.4 inducer and 104 exducer compressor wheel. Lots of up pipe passage porting and he will also change my downpipe to an HX40 flange to fit my fleece downpipe. Any help would be appreciated
