look what u asking me, i doh drive a rotree nah honestly, don't know the specs and the exhaust gases, considering the higher comp. than a turbo engine u running would probably make me think between 2 and 3k rpm's which would be a sweet spot since these cars make power from that part of the power band
assuming it fit (i can't say for sure), it won't be ideal. might get boost about 1000 rpm earlier. t25 or t28 and stock manifold will make some good power. pulsar t28 would be ideal.
