just curious how would this conversion go in a A31 Cefiro? and gearbox wise i've heard that the best gearbox to use for a cefiro drivetrain conversion is a VLTurbo MX7 gearbox because it runs a cable speedo drive? and out of the MX7 and the R33 which is the better box would they handle alot of power and which one 'feels' the best for those with experience? cheers
