I am thinking of buying pipes
My long therm goals will be to put a mc21 hrc tt-f3 motor in a mc28
Is it possoble to use a mc28 rotor on a hrc motor ? If it is not can you change the crank web on that side to take the mc28 rotor

Will the best pipes for a tt-f3 motor be RS250 nf5 pipes with jha flanges ... ?
