My mates EP3 Type-R could out-accellerate my std VX220 above 100 leptons at Bruntingthorpe - thats with a 250+KG advantage - they are very quick once they are moving (and aerodynamics are key) having a half decent driver who can keep it in the power band.
Id agree with jamee at 215-220BHP, in that case the Z22SE would have much more torque for the bottom end to pull your extra weight and a comparable terminal speed. In other words, not really worth it 🙁
