The VF26/27 combo is the best available for the twins....they will flow better and produce more power than the Vf32/33 combo from the rev d BH models. Straight forward bolt on upgrade for the 26/27, tho a remap would give the best of these. I had my 97 RS-B JDM mapped to 310bhp on original VF18/19 combo, with an ESL daughterboard fitted in the 4G ECU. Ultimately the most power you could get from the 26/27 is around 320bhp..........single turbo conversion is way forward!!
