stupid idea. the gs-r i/m has dual set of butterflys. one opens up at 4400rpm and the second at 6000rpm. so unless you get a chipped gs-r ecu then theres no point. just get the obd2-1 harness made and chip a p28. it will dump fuel and make you happier. and it will change your vtec crossover point. sometimes if you go to the right person they can set your vtec at whatever you want like custom sort of. but to simply answer your question no it won't benifit you. good luck.
